Environment variables in alphabetical order

C

CASSPOOL_LOCK_RETRY_COUNT
Category: JES
If errors are experienced by the spool module, the number of times it retries to obtain a record lock can be adjusted using this environment variable.

Syntax

SET CASSPOOL_LOCK_RETRY_COUNT=count

Values

count The number of retries made to obtain a record lock.

Default

If not specified, this variable defaults to 20.

CCITIMEOUT

Allows the specification, in tenths of seconds, of the maximum time out period that will be used with any LSC style application, such as Drag and Drop, SourceConnect, or the Monitor. The maximum value that can be used is 2,147,483,647.

Syntax

SET CCITIMEOUT=value

Default

The default is 1200 (2 minutes).

Example
This example sets the value to 4 minutes:
SET CCITIMEOUT=2400 
CCIERRLOG
Specifies the output location and filename of ccierr.log content which tracks first-instance errors reported from the operating systems. CCIERRLOG overrides any entries found in CCI.INI, where the syntax and content is explained in detail.
CCITCP2
Instead of using the CCI Configuration Utility to set the TCP address of the machine running the CCITCP2 registration daemon the environment variable "CCITCP2" can be used instead. This may be useful if you need different processes on the same machine to contact different registration daemons.

Syntax

set CCITCP2=hostname

Parameters

hostname is the TCP hostname or dotted decimal IP address of the machine running the CCITCP2 daemon you wish to contact from that session.

Comments

The environment variable value will always take precedence over any value set using the Configuration Utility. To restore a process to using the value set by the Configuration Utility simply set the environment variable to an empty string, such as

set CCITCP2=

Alternatively, if this environment variable is set system-wide (by creating a system variable in the system environment settings, or by using a CONFIG.SYS file) then this value will always take precedence over any value set using the Configuration Utility.

CCITCP2_PORT
The port that is being used for the registration process.

Syntax

set CCITCP2_PORT=port
Parameters
  • port The port on which the CCITCP2 registration program operates.
CCITCPS
To start a CCI server on a fixed port, you can associate the Server Name with the port value by using the CCITCPS_ environment variable instead of appending the information on the Server Name itself.

Syntax

set CCITCPS_server_name=port

Parameters

  • server_name is the name of the CCI server
  • port is the fixed TCP post to use

Note that this will only work if the server application process is started in the same session or process that has this environment variable set.

Example

set CCITCPS_server_name=MFPORT:3000
CCITCPT

If a client is known to be trying to connect to a server with Server Name server_name, and the TCP address and port (e.g. 3000) that the server is using is known, then the client can be made to connect directly to it by setting this environment variable.

Syntax

CCITCPT_server_name=MFNODE:server_hostname,MFPORT:port_number

Note that this can be used instead of setting the client Machine Name value. This is useful if the Machine Name value the client specifies cannot be altered by an application defined method.

Parameters

  • server_name The server to which the client is trying to connect.
  • server_hostname The TCP address.
  • port_number The TCP post number.

Example

CCITCPT_server1=MFNODE:server2,MFPORT:3000
CCITRACE
Part of the process to enable CCI tracing is to specify the degree of information that will be traced, which can be done by setting the CCITRACE environment variable as follows:

Syntax

CCITRACE=filename [options]
Parameters
  • filename The name of the log file you want the trace output to go to. If you do not specify this parameter, the log file ccitrace.log is created in the current directory with all options set to their default states.
  • options Any, or all, of the following:
/F or -F logs the details of CCI API calls to the trace file. The default is OFF, unless a filename any other trace option is specified, in which case it is always ON.
/P or -P logs the details of protocol-level calls to the trace file. The default is OFF. If this flag is OFF, then only the details of the CCI user-level API will be traced. If this flag is ON, the level of function tracing may be greatly increased.
/D or -D logs the contents of all buffers passed to and from the CCI functions. The default is OFF. Data tracing may not be allowed if the application has been coded to prohibit data tracing for security reasons.

So to create a CCI trace file with the default name of ccitrc1.trc (with matching ccitrc1.idx file) which traces CCI API function flow, along with the underlying protocol function flow, but with no tracing of the user data passed to these calls, the value of the CCITRACE environment variable would be /P.

The CCI.INI file can also be used to control trace options, but any values specified by the CCITRACE environment variable will take precedence.

CICS_SIT
The name of the SIT used by the region.
Values
  • The name of the SIT that the region uses.
COBCONFIG

Specifies a run-time configuration file that tailors the run-time configurable options in some way.

Syntax

SET COBCONFIG=pathname

Parameters

  • pathname The name of the COBOL configuration file that tailors the runtime

Comments

If $COBCONFIG is not set then the file $COBDIR/etc/cobconfig is searched for instead.

Example

SET COBCONFIG=/home/mydir/cobconfig
COBCONFIGJVM
Specifies a Java properties file that tailors the run-time configurable options for Java Virtual Machine applications. Use this instead of COBCONFIG in COBOL applications intended for use on a Java Virtual Machine.

Values

  • The location of a properties file.
COBCONFIG.BLOCK
The location of the application configuration file.
COBCPY

Specifies the directory or directories that the Compiler and Animator should search for copyfiles.

Syntax

SET COBCPY=pathname[:pathname]...

Parameters

  • pathname

    A directory that the Compiler and Animator are to search when looking for copyfiles. When more than one pathname is present, a null pathname represents the current working directory.

Example

SET COBCPY=/home/group/sharedcopy::mydir/mycpy

causes the Compiler to search for a copyfile in /home/group/sharedcopy, then in the current directory and finally in ./mydir/mycpy until either the copyfile is found or it can be considered not found.

COBDATA
Specifies one or more locations, separated by ; (Windows) or : (UNIX), in which to search for data files at run time. As long as the file assignment does not contain a sub-path (that is, a string containing \ or /) then the file assignment is appended to each location specified by COBDATA in order to locate the file.
Note: Users modernizing RM/COBOL or ACUCOBOL-GT legacy code can use a sub-path in the file assignment, but only by compiling with the relevant DIALECT or IDXFORMAT values for the respective File Handling systems; setting these values in the File Handling configuration file is not sufficient to achieve this.

Specifies the directory or directories that the run-time system is to search for data files. Provides you with the facility to map data files globally, thus enabling you to put working data files in a directory whose name is not known until run time.

Syntax

COBDATA=pathname[:pathname]...
Parameters
  • A list of search directories, each item separated by a semicolon. The runtime system is to search these when looking for application data files. When more than one pathname is present, a null pathname represents the current working directory.

Comments

COBDATA affects the compiler and other utilities. During compilation, for example, program source is regarded as a data file by the compiler. If you intend to use any COBOL development system utilities, we recommend that the COBDATA value starts with a colon (:).

COBDATA is considered set if there is an environment variable of this name in your environment space, and its value is non-empty.

The full mapping order for files is:

  1. Any dd_ environment mappings
  2. Any ASSIGN TO EXTERNAL mappings
  3. Any COBDATA environment variable mappings

For multiple directory paths specified either in the COBDATA environment variable or a dd_ environment variable, the system searches the first directory specified followed by a slash (/) as a prefix to the user name.

If the filename is not found, or is not readable, the search continues with the next directory until the final directory has been searched. If no file is found, the first directory is used if a file is to be created.

Any dd_ and COBDATA mappings are ignored for any filename that starts with a hyphen () or a slash (/). In addition, it is illegal to have a hyphen in an environment variable name.

When using this facility, you should not use a filename that starts with "COB... "(these are reserved for the COBOL system).

You can use the COBDATA environment variable for files open in any mode (including OUTPUT) and for fixed or variable length files. If you are using indexed files, both the data and index files must be in the same directory.

The COBDATA environment variable affects file deletes, using the rules given here, as well as file opens.

If you intend to use COBOL development system programs, we recommend that you first unset COBDATA, as many of these programs open data files and are thus affected by the value of COBDATA. If you have to set COBDATA, you should include the paths :$COBDIR/dynload/helptbox.lbr and :$COBDIR/dynload/check.lbr at the beginning of the COBDATA value. If you want to see the Animator Help pages, also include COBDIR/dynload/advanim.lbr.

Note: Users modernizing RM/COBOL or ACUCOBOL-GT legacy code can use a sub-path in the file assignment, but only by compiling with the relevant DIALECT or IDXFORMAT values for the respective File Handling systems; setting these values in the File Handling configuration file is not sufficient to achieve this.

Example

SET COBDATA=:demo:/home/data:progs

causes COBDATA to be set to instruct the runtime system to search for data files in the current directory, then in the directory ./demo, then in the directory /home/data and finally in ./progs.

COBDIR

Specifies the directory where the required Micro Focus COBOL system is installed. Many of the COBOL system components and utilities require and use this information. If the COBDIR environment variable is not set then the COBOL system acts as if it had been set to the default COBOL system directory.

Syntax
SET COBDIR=pathname

Parameters

  • pathname The directory that contains the required Micro Focus COBOL system software.

Comments

The Micro Focus COBOL system is normally installed in the default COBOL system directory and so does not require COBDIR to be set. COBDIR only needs to be set when your COBOL system has been installed in a different directory such as when more than one version of the COBOL system is available at the same time.

Example

SET COBDIR=/home/products/cobse20

This causes the Cob utility to search the directory /home/products/cobse20 for the Micro Focus COBOL system software.

COBJVM

Specifies which Java Virtual Machine (JVM) to load.

Syntax
SET COBJVM=platform_nnn

Parameters

platform_nnn where

platform is a threecharacter code that indicates the platform on which you are running Server Express, for example:
  • ibm IBM AIX
  • unx SCO UnixWare
  • sun Oracle SPARC
nnn indicates the version of the JVM, for example:
  • 122 Version 1.2.2
  • 130 Version 1.3.0

Comments

You might need to set COBJVM if you are developing distributed applications with both COBOL and Java components.

Example

SET COBJVM=ibm_122
COBKEYTIMEOUT

Specifies the maximum elapsed time, in tenths of a second, for the connected terminal to transmit any valid escape sequence to the runtime system.

When a terminal key is depressed, the terminal might send in response a single character or a group of characters to the runtime system. Typically, such a group of characters starts with an escape character and the group of characters is known as an escape sequence. A terminal might send an escape sequence for one depression of a function key. It might also send the same sequence of characters for a depression of the Escape key followed by the depression of one or more alphabetic or numeric data keys. The only difference apparent to the runtime system is the interval between the arrival of each character; the user cannot type as fast as the escape sequence is generated by the terminal.

If a terminal is connected over a network that sends the characters to the runtime system in discrete packets, then the network can alter the intervals between each character arriving at the runtime system. COBKEYTIMEOUT is available to help compensate for typical network delays so the runtime system identifies escape sequences correctly.

Syntax

SET COBKEYTIMEOUT=n

Parameters

n A number in the range 1 through 126 that represents the maximum elapsed time required for a terminal to transmit any valid escape sequence to the runtime system over the line or network connection. On encountering a lone Escape character, the runtime system waits n tenths of a second before assuming that the character does not introduce an escape sequence. The runtime system calculates an appropriate default value for n from the baud rate of the terminal.

COBLANG
The language environment in which your COBOL program runs.
Values
  • A COBOL language environment (LE) value.
COBLPFORM
This configuration variable is used to define and print to printer channels C01-C12. Specify the line numbers for each channel with the COBLPFORM configuration variable. Null entries are ignored. Those channels that have line number zero, function-names S01-S052, CSP, or are undefined, are set to line 1.

Example 1:

COBLPFORM 1:3:5:7:9:11:13:15:17:19:21:23

In this example C01 equals 1, C02 equals 3, and so on.

Example 2:

COBLPFORM :3::5: :9

In this example, C01 equals 3, C02 equals 5, C03 equals 1, and C04 equals 9. You can specify only a single line number for each channel.

In example 2 above, channels C05 - C12 are undefined. If a print statement specifies channel C05 - C12, the line is printed at line 1. In addition, in the example shown, C03 equals 1 because its value is a space and therefore undefined.

Any WRITE BEFORE/AFTER PAGE statements cause positioning to be at line 1. Each line advance increases the line number by one. A request to skip to a line number less than or equal to the current line causes a new page to begin. The appropriate number of line feeds are then generated.

COBMAINSTACK

Specifies the size of the main stack.

Syntax

SET COBMAINSTACK=n

Parameters

n A number in the range 1 through nnn that represents the size of the main stack.

Comments

You might need to set COBMAINSTACK in any of the following circumstances:

  • If you are deploying OO COBOL Enterprise JavaBeans (EJBs) to WebSphere on the AIX platform
  • If you are using the multi-threaded run-time system

    If you have IF STATEMENTS with a very large number of ELSE clauses

COBPATH

Specifies the directory or directories that the runtime system is to search for dynamically loadable .int and .gnt files, or callable shared objects.

Syntax

SET COBPATH=pathname[:pathname]...

Parameters

pathname A list of search directories, each item separated by a semicolon, that the runtime system is to search for a dynamically loadable program (.int, .gnt or callable shared object) file. When more than one pathname is specified, a null pathname represents the current working directory.

Example

SET COBPATH=u:/home/mydir/srclib:otherlib
COBPRFDIR
Location of .ipf files created by programs compiled with the PROFILE compiler directive.
Values
  • A list of search directories, each item separated by a semicolon.
COBPRINTER

Specifies the name of a print spooler that is to receive, via its standard input stream (stdin), output from any DISPLAY UPON PRINTER statement.

Syntax

SET COBPRINTER=command-line

Parameters

  • command-line A command line supported by your system and that can be executed by the system shell. Typically, it is simply the name of a print spooler or other executable, but if the shell is escaped when setting the value then any command-line arguments can be used.

Comments

Each DISPLAY UPON PRINTER statement executed by your COBOL program causes a new invocation of command-line. Each invocation receives the data referenced in the DISPLAY statement, and is followed by a system end-of-file condition.

Example

SET COBPRINTER="myspooler -a $TMPDIR\spoolfile"
COBSSL
If using SSL connections specifies the location of the DemoCA directory. If not found, SSLDIR is inspected instead.
COBSW
Specifies the run-time system switch settings for the run-time system to observe when running an application.

Syntax

SET COBSW=[+/-}s...
Parameters

A list of the runtime switches to set or unset.

  • + sets a switch.
  • - un-sets a switch.

Example

SET COBSW=+0+D

This enables runtime switch 0 and the ANSI COBOL debug switch.

Values

  • The location and name of the default database.
DBG_MVSPSKEL
The skeleton JCL for debugging.

E

ENTRYNAMEMAP
Specifies the locations of entry name map files to be used.

Syntax

SET ENTRYNAMEMAP={filename|directory}; ...

Parameters

filename An entry map file.

directory A directory containing an entry name map file. The name of the entry name map file must be mfentmap.dat.

Comments

You must set the entry_name_mapper tunable to enable entry point mapper support.

If ENTRYNAMEMAP is not set, the runtime system searches for an entry name map file called mfentmap.dat in each folder specified by the COBDIR environment variable.

If the runtime system finds more than one entry name map file and same entry point is defined differently in different files, precedence is given to the definition in the entry name map file that was found first. To change the order in which the runtime system finds entry name map files you need to change the order in which the files appear in the COBDIR or ENTRYNAMEMAP environment variable paths.

ES_ABORT_PLTPI_ERROR
Enables the user to set the error on which to abort PLTPI processing, bypassing the prompt.
Syntax
ES_ABORT_PLTPI_ERROR=xx
Values

Values for xx can be:

  • YN - Abort on PGMIDERR
  • NY - Abort on ABEND
  • YY - Abort on PGMIDERR or ABEND

Comments

By default, when an error occurs during PLTPI processing, mainframe CICS enterprise servers display a prompt that enables the user to cancel the startup or ignore the error. Set ES_ABORT_PLTPI_ERROR to bypass the prompt and automatically abort the initialization as dictated by the value provided.

Default
If this is not set, mfuser will be used as the default user to sign in to ESMAC.
ES_DFS3650
The default transaction to execute or MOD file to be displayed after successfully signing on to IMS. You specify these by setting environment variables prior to the start of the region: ES_DFS3650 - set to MOD if a MOD file is to be sent, or TRX if a TRANSACTION is to be executed. If you set to MOD, ES_MOD3650 needs to be set to the name of the MOD you want to display. If you set to TRX, ES_TRX3650 needs to be set to the name of the transaction.
Syntax
ES_DFS3650=value
Values
  • MOD - ES_MOD3650 needs to be set to the name of the MOD you want to display
  • TRX - ES_TRX3650 needs to be set to the name of the transaction
Default
No default transaction or MOD.
ES_ECI_MAX_RESP
Specifies the maximum expected response size (in bytes) to use when using Micro Focus ECI support to invoke CICS programs.

Syntax
ES_ECI_MAX_RESP=value
Values
  • Maximum value is 16777215.
Default
If this is not set, the maximum expected response size is calculated dynamically by multiplying the size of the TIOA by 2.
ES_ESM_CMDSEC
Indicates whether CICS processing honors the CMDSEC option specified on a transaction's PLT definition.
Syntax
ES_ESM_CMDSEC=value
Values
  • YES - CICS overrides the CMDSEC option, and always calls its command security checking routine to issue the appropriate call to the SAF interface
Default
CICS honors the CMDSEC option defined in a transaction's resource definition. CICS calls its command security checking routine only when CMDSEC(YES) is specified in a transaction resource definition.
ES_ESM_IDPW_CASE
Forces the case of user ID and password for single attempt ESM authentication. You use the environment variable with a format ES_ESM_IDPW_CASE=xy, where "x" is the folding option for user ID, and "y" the option for password.
Syntax
ES_ESM_IDPW_CASE=xy
Values

Values for both x and y are:

  • U - Always upper case.
  • L - Always lower case.
  • M - Mixed case and case sensitive

Default

Legacy behavior.

Comments

When this environment variable is set, Enterprise Server will only make one attempt to identify a user presenting the user ID and password as is (M), folded to uppercase (U) or folded to lower case (L). If this environment variable is not set, the legacy Enterprise Server behavior will be used.

For the legacy behavior for CICS, the User ID and the password are used as supplied possibly filtered by the uppercase translation configuration of the sign-on transaction.

For ESMAC and IMS, the legacy behavior is that, first, the user ID and password are used as supplied. If the authentication fails, the user ID is folded to uppercase and used again. If this fails as well, both the user ID and the password are folded to uppercase and then used.

Example

ES_ESM_IDPW_CASE=UM - a single authentication is tried with the user ID folded to uppercase, and the password used as-is.

ES_ESM_PLTPISEC
The level of security checking for PLTPI processing.
Syntax
ES_ESM_PLTPISEC=value
Values
  • NONE - You do not want any security checking on PLT initialization programs.
  • CMDSEC - You want CICS to perform command security checking only.
  • RESSEC - You want CICS to perform resource security checking only.
  • ALL - You want CICS to perform both command and resource security checking.

Default

NONE

ES_ESM_PLTPIUSR

Values
  • userid - The userid that CICS is to use for security checking for PLT programs that run during CICS initialization.
ES_ESM_RCF
Determines how RACF is used for command authorization
Syntax
ES_ESM_RCF=value
Values:

ES_IMS_LTERM_PREFIX
Note: This is a technology preview feature only. It is being made available to allow you to test and provide feedback on this new capability; however, this feature is not intended for production use and it is not supported as such.

Enables specification of a one- to four-character alternative LTERM prefix to apply when ES_IMS_SINGLE is set to N. The default is OTMA.

The default setting of this environment variable suggests that the LTERMS apply only to OTMA clients; however, this is not the case. LTERMS can also be applied to second and subsequent 3270 user connections.

To avoid confusion with regard to OTMA, and to also exercise control over name conflicts, change the default setting to a prefix of your choice.

In addition, Enterprise Server pads the value specified with numeric digits up to eight characters, enabling the LTERM pool to be expanded from 9999 up to 999999. The pool size is dictated by the number of characters used in the specified prefix. For example, the LTERM pool size for a four-character prefix is 9999; for a three-character prefix is 99999; and so on.

ES_IMS_LU_LTERM
Determines the value of the LTERM literal returned by the MFS system. Valid values are: Y to return the LU name; N to return the user ID.
ES_IMS_MESGQ

Y Cold start the resource definitions. Default.
S Cold start the statistics and resource state information.
Q Cold start the data store (system cold start).
cushion-size
The size of the cushion to be reserved for graceful lack-of-space behavior, represented as a number from 0 to 255. The specified number represents 32 times the actual percentage of max-blocks reserved for emergency use. The default is 4 (a raw value of 128).
ES_IMS_OPEN_TIMEOUT
Defines the wait period in seconds during which IMS retries the opening of a database file that is in use by another task. Default is 30 seconds.
ES_IMS_OTMA_DEST
Each specified destination consists of the destination name, the NONOTMA keyword, and the LU type (LU1 or LU3) separated by commas. Each destination definition is separated by a semi-colon.
IMS_OTMA_DEST=printerName,NONOTMA,LUtype[;...]
ES_IMS_PATH
The location of compiled COBOL applications.
ES_IMS_PLI_INDIRECT_PCBADDR

Determines whether the PL/I program converts the PCB address list from a direct to an indirect addressing technique. Set the variable to one of the following:

D
If the main program is a PL/I program, PCB addresses are converted from a direct to an indirect addressing technique.
Y
Always converts address as long as the PSB language is PL/I.
N
Never converts addresses.

The default is D (which stands for dynamic).

ES_IMS_RELEASE
Allows the user to specify the IMS Release returned to the AIBTDLI INQY ENVIRON call.
ES_IMS_REGION
Allows the user to specify the IMS Region returned to the AIBTDLI INQY ENVIRON call.
ES_IMS_ROLLBACK
Enables automatic Backward Recovery; enabled by default.
ES_IMS_ROLLFORWARD
Enables or disables Forward Recovery logging. Valid values are: Y to enable; N to disable. The default is N.
ES_IMS_SINGLE
Note: This is a technology preview feature only. It is being made available to allow you to test and provide feedback on this new capability; however, this feature is not intended for production use and it is not supported as such.

Enables specification of a one- to four-character alternative LTERM prefix to apply when ES_IMS_SINGLE is set to N. The default is OTMA

When ES_IMS_SINGLE is set to N, and a user attempts to sign on to an LU using a sign-on that is currently active at another LU, IMS Transaction Manager (TM) assigns a temporary LTERM to the user and LU using a name constructed from the ES_IMS_LTERM_PREFIX setting followed by a numerical value totalling eight characters (see the IMS_LTERM_PREFIX entry in this topic for details). The temporary LTERM is the destination for the user and LU irrespective of activity at other LUs controlled by the user. When a user disconnects from an LU that is served by a temporary LTERM, the LTERM is returned to the temporary pool for reuse.

Also when ES_IMS_SINGLE is set to N, the execution of /dis USER all returns a sublist for each user showing all active connections. These connections persist throughout a session, and are dynamically recreated during a warm start.

No KEYPOINT activity is associated with the use of ES_IMS_SINGLE.

ES_IMS_SPARSE_EXIT_LANG
Indicates the language of the IMS DB secondary index sparse routines. Set the variable to one of the following values:
  • C (for COBOL)
  • A (for Assembler)
By default, this variable is not set (sparse exits are disabled).

Note: When enabled, Enterprise Server reclaims space in the file when information becomes obsolete.
ES_IMS_TLOG_FLUSH
When set to 1, forces the frequent flushing of TLOG and database buffers to disk.
Warning: Depending upon the number of database updates, the frequency of commits, and other computer activity, use of ES_IMS_TLOG_FLUSH could result in significant performance degradation.
Note: This environment variable is deprecated. Use ES_IMS_DB_TLOG_WRITETHRU to flush TLOG buffers and ES_IMS_DB_COMMIT_FLUSH to flush database buffers.

ES_TMC_AGGREGATE
Controls the performance environment for IMS TM data stores.

Syntax

SET ES_TMC_AGGREGATE={[,N|,D]|nnn,Y}

Values

,N
Sets the default behavior, which is to unilaterally flush operating system buffers to your physical disk at each key transactional point. While this does not change the method used by default at startup, it does enable dynamic modification via ESMAC. Once set, you can then test the effect of various non-default settings by altering them dynamically.
,D
Disables the transactional flushing of operating system buffers to disk. This option can significantly enhance message queue performance; however it is at the expense of the transactional integrity of the message queue in the event of a system failure.
Note: To avoid unpredictable results when using this setting, we highly recommend that you also set the static options as follows on the Administration Server > Properties > MSS > IMS > TM > General tab:
  • Set Cold start to Everything (queue)
  • Check Persist

See Server Instance Properties: MSS IMS TM General for details.

nnn,Y
Enables the aggregated transactional flushing of operating system buffers to disk where nnn represents an interval of time, in milliseconds, during which additional buffers are allowed to accumulate before flushing. Valid values are 0 through 255.

Once a thread reaches a key transactional point and requests a flush, TM waits the specified interval to accumulate subsequent threads that also request a flush. At the end of the interval, one flush is performed for all accumulated requests thus potentially improving performance by reducing the number of flush commands issued to the operating system.

Note:
  • Threads requesting a flush wait until the flush is confirmed.
  • Generally, when the message queue resides on a higher performance I/O subsystem such as one using SSDs, a smaller value, e.g. 1 or 2, produces the best results. A value of 10 or higher seldom improves performance.

Default

,N

H

HCOBND (deprecated)
Specifies a directory to be used for bind files generated by the DB2 External Compiler Module (ECM).
Note: HCOBND is deprecated, and provided for backward compatibility only. We recommend that you use either the BIND or the BINDDIR compiler directive option instead.

Syntax

SET HCOBND=pathname
HCOBND=pathname
export HCOBND

Parameters

pathname The directory that the DB2 ECM is to use to store bind files.

Example

SET HCOBND=d:\mydir\binds

Comments

The DB2 ECM uses the specified directory until the variable is unset or reset to a different directory. The DB2 Compiler directive option BIND overrides this environment variable.

I

ICONN1
Controls the client TCP connection status of an IMS Connect emulator.
IMSCPY
The location of copybook files for DBDGEN, PSBGEN and MFSGEN utilities .
ISPPROF
The location of ISPF dialog profiles.

J

JAVA_HOME
Specifies the location of the JDK.

L

LIB
The location of the DB2 LIB directory

M

MAINFRAME_FLOATING_POINT
Specifies the format to use for floating point data items. Possible formats are IBM hexadecimal and IEEE.

Syntax

SET MAINFRAME_FLOATING_POINT=fpstatus

Parameters

fpstatus Which format to use for floating point data items. This must be one of:

  • true Specifies that IBM hexadecimal format floating point data items are to be used.
  • false Specifies that IEEE format floating point data items are to be used.

Setting MAINFRAME_FLOATING_POINT to anything other than true has the same effect as setting it to false.

The setting of this environment variable can be overridden by the NATIVE-FLOATING-POINT directive.

MF_ALIAS
Specifies program aliases. Each set (pair) is 16 characters long - 8 characters for the program-name, and 8 characters for the alias. You can specify up to 10 pairs. This list is searched first and thus can potentially override the built-in list. If not found, the built-in alias table is searched.
MF_AMODE31ONLY
Indicates that all programs are AMODE(31).
MF_CBLQDA
Determines if QSAM files are dynamically allocated when processing an OPEN I-O or OPEN EXTEND statement for an optional file (that is, a file opened using the SELECT OPTIONAL syntax in the FILE-CONTROL paragraph) or a file opened for OUTPUT (regardless of whether it is optional or not). Permissible values are OFF and ON; the default is OFF, which specifies that dynamic allocation is not permitted.
This is an emulation of the CBLQDA Language Environment (LE) run-time option.
When set to ON, and your JCL contains a misspelled or no DD statement for the file being opened, a temporary file is created as a result of the OPEN statement, and then deleted after the program has run. For optional files opened for I-O or for EXTEND, you receive a return code of 05; for files opened for OUTPUT, you receive a return code of 00.
This variable has no effect on VSAM applications or the JCL utility programs.
Note: For programs that use ESDS files and have this variable set ON, ensure that FILETYPE is set to 15 or 16; otherwise these files will be affected by the variable, and treated as QSAM files.
MF_CHARSET
Specifies the system character set (ASCII or EBCDIC).
MF_DUPJOBS
Enables jobs with identical names to run.
Values:
  • Y (Default)
  • N
MF_FALLTHRUCHECK
Specifies that MSS is to check that the main COBOL program ends by executing a GOBACK or STOP RUN.
Values:
  • y (default)
  • n
MF_JCL_AUDIT
Specifies that the audit log records audit information when a catalog entry is deleted.
Values:
  • DLET - Logs audit information each time an ESMAC/CAS utility deletes a catalog entry
  • DLEJ - Logs audit information each time a step in a JCL job deletes a catalog entry
  • DLET,DLEJ - Logs audit information each time either an ESMAC/CAS utility or a JCL job step deletes a catalog entry
MF_MFA
Specifies what dataset catalogs are to be searched.
Values:
  • ALL - Search for datasets first in the local catalog, and if not found, on the mainframe (default)
  • RJSE - Search for datasets in the local catalog only. No mainframe is performed.
MF_MVSJOB
Sets the number at which a job starts and finishes.
MF_MVSJOB=<lower value>{-|+}<upper value>
Where:
<lower value>
Number at which a job starts. Contains 7 digits - for example, 0000001
-
Sets the values but only on the first startup of the region.
+
Reset the values to these new ones each time the region is started.
<upper value>
Upper job number. Contains 7 digits - for example, 9999999
For example:
set MF_MVSJOB=0000010+0000100
This resets the values to start with job number 10 and run through to job number 100. When the upper limit has been reached you receive a message:
All job numbers in the range 0000010:0000100 are in use
At this point you need to remove some jobs from the spool - you can use the spool housekeeping functions to do this.

This environment variable can be used to enable a 7-digit Job number limit. If the <upper value> mentioned is greater than 99999, then 6+ digit job number support is enabled. The maximum value that can be set is 9999999.

Tip: To revert to 5-digit job number support, set MF_MVSJOB=<low number>+<high number>, where high number is less than 0099999, and ensuring that the + sign is used to separate the low and high values.

If a value set using this variable is not valid, the default values of <0001000>{-|+}<0099999> are set.

MF_NEWSPACE
Indicates whether SPACE is required for NEW datasets.
MF_PCRENAME_LAX
When an MVS dataset is renamed, the associated physical file is normally renamed only if it is in the Default Allocation Dataset Location (which is the default, MF_PCRENAME_LAX=N). Set MF_PCRENAME_LAX to Y to enable physical files in other locations to be renamed if the cataloged name is changed. Set MF_PCRENAME_LAX to D to indicate that a new directory structure and filename will be constructed, and the existing file moved to that location.
MF_NODD
Specifies what action MSS is to take at run time if a job step uses a file that has not been allocated.
MF_RCCF
Enables Remote Job Step Execution (RJSE).
MF_ROOT_CERT
Enables the MF Directory Server process and any client applications to pick up the value of the root certificate file.
MF_SMS
Enables SMS support

Default

The default is Y.

MF_SYSLOGDSN
The Syslog Dataset name.
MF_UCC11
Enables emulation of UCC11, a third party add-on to the mainframe that affects data set disposition processing. If UCC11 is enabled, a data set disposition of NEW is accepted even if the data set already exists.

Syntax

SET MFCSCFG=filename

Parameters

filename The name of the configuration file.

Example

SET MFCSCFG=/home/mydir/mfclisrv.cfg

Comments

The value of MFCSCFG is overridden by any value defined in the command line. If neither of the above yields a filename, the default filename mfclisrv.cfg is assumed, and is searched for in the current directory. If that in turn is not found, the default settings for the configuration entries are used.

MFE.SMS
Enables SMS support.
MFEXTMAP
Location of a mapper file.
MFIMS_ACBDUMP_TIMESTAMP
Suppresses date/time stamp display in ACB report.
MFIMS_BMPCHKP
Returns a QC to a checkpoint call when it the call includes an IO area.

MFIMS_PCBCALL
Allows a standalone EXEC DLI program to issue a PCB call.
MFJ_ALL_STEP_CHECK
The default behavior of this product is to not check COND CODES from steps prior to a restart step. This means that the steps after the restart step that have conditions that refer to any steps prior to the restart step might run. This is a change of behavior from releases 4.0 Patch Update 1 and earlier when these steps would have not run. Micro Focus recommends that you review and test the behavior before restarting the jobs.

Set this variable to Y to prevent steps after a restart step that have conditions that refer to any steps prior to the restart from running.

MFJ_INPUTDS_ERROR
When set to N, this will cause IEBDG, IEBGENER, IEBCOMPR, and DFSORT and ICETOOL emulation to treat missing files as though they were present but empty.
MFJSABCODE
Determines the abend (abnormal end) code issued when MFJSERET=ABEND is in effect. If a Sort or Merge operation fails with an unrecoverable error, it will abend with a code between S001 and S063.

Syntax

SET MFJSABCODE=code

Parameters

code A decimal value between 1 and 99 representing the abend code to be issued.

Any specified value outside of the range 1 to 99 will result in an abend code of S00D being issued.

Default

By default, this environment variable is not set. If so, and if MFJSERET=ABEND is in effect, an abend S00D (decimal code 16) is issued when a Sort or Merge operation fails with an unrecoverable error.

Example

MFJSABCODE=77

This example results in abend code S04D being issued.

MFJSENGINE
Specifies which sort engine the utility MFJSORT is to emulate.

Syntax

SET MFJSENGINE=value
Values:
  • DFSORT Emulates DFSORT
  • SYNCSORT Emulates SYNCSORT

Example

Default

The default is DFSORT.

MFJSERET
If this environment variable is not set, an unsuccessful operation and its program will terminate with an unrecoverable error (return code 16). See also MFJSABCODE.

Syntax

SET MFJSERET=ABEND

Parameters

ABEND The operation will abend and its program will continue instead of terminating with an unrecoverable error (return code 16)

Default

By default, this environment variable is not set.

MFJSSTRICTSORT
Enables or disables the following mainframe behavior:
  • All JCL statements must contain a SYSOUT parameter, otherwise they will abend.
  • Modification of a ZD number with value 0 through INREC or OUTREC processing now keeps its sign value.
  • Records that are shorter than the output file's LRECL will be padded with low-values instead of spaces.
  • Input RECFM is identical to the output RECFM or OUTFIL RECFM (unless FTOV or VTOF/CONVERT has been specified), otherwise it errors with return code 16.

Syntax

SET MFJSSTRICTSORT=ON|OFF

Default

The default is OFF.

Example

MFJSSTRICTSORT=ON
MFJSTATS

For a COBOL sort not running under mainframe emulation, setting the environment variable MFJSTATS to ON creates a report containing statistics for the SORT that is displayed to SYSOUT. If a report file already exists for a previous SORT, the new statistics are appended to the end of the previous one.

If you are performing a COBOL sort using mainframe emulation, you can create a statistics report by modifying the JCL statement.

Syntax

SET MFJSTATS=switch

Parameters

switch Switches report creation ON or OFF. The default is OFF.

MFJSWINDOW

Use this environment variable for Y2K compatibility, when two-digit year values are used.

Syntax

SET MFJSWINDOW=value

Values

To set a sliding century window, set a value between 0 and 100. For example, a value of 80 would set a century window of 1931-2030 in 2011, 1932-2031 in 2012, and so on.

To set a fixed century window, set a value between 1000 and 3000. For example, a value of 1973 would set a century window of 1973-2072.

Default

The default is a sliding value of 80 when emulating DFSORT, and a default value of 0 when emulating SYNCSORT. A value of 0 equates to a century window, starting in the current year.

Comment

You can use this environment variable instead of the Y2PAST sort option.

Example

MFJSWINDOW=25
MFLECONFIG

Specifies a configuration file for Language Environment (LE) runtime options.

Syntax

SET MFLECONFIG=filename

Parameters

filename The file containing the LE runtime options you want to use.

MFLOCKING
Enables Locking Support

MFREXX_OR
One or more characters to be used for the OR operator in addition to REXX's default, which is "|".
Values
  • One or more characters for each operator; each character you specify is used in addition to the default operator. Each additional character must be defined within single or double quotes, or in hexadecimal. Separate multiple characters with a space or a comma.
MFSUB
Specifies whether to use SUBI or ASUBI.
Values
  • SUBI
  • ASUBI

P

PROCLIB
When set to ON and under a mainframe emulation, a file status of 37 is returned when you open an existing VSAM file for OUTPUT and the file has or previously had some data written to it, or if the file format is different from the file on disk. The default for this variable is OFF.

R

RANDOM
If using SSL connections, externally generated random data that is stored as a numeric value in the RANDOM variable will be inserted into the initial salt value used to generate temporary key pairs used in SSL hand-shaking. The RANDOM value will only form part of the initial salt value and is an aid to generating more randomness and not an essential requirement.

S

SORTCOMPRESS
Tells the system whether or not to execute a compression routine on each record to be sorted.

Syntax

SET SORTCOMPRESS=5

Parameters

5 This is the only value that you can supply. It allows for run-length encoding of sort records, resulting in much better performance when records contain multiple repeated characters.

Comments

This variable is recommended if the sort records contain many single repeated characters, for example, multiple spaces, as it can be very effective in improving memory usage and therefore sort performance.

Example

SET SORTCOMPRESS=5
SORTSCHEME
Activates a sortscheme. Use in conjunction with SORTSPACE for improved performance.

Syntax

SET SORTSCHEME=1
Values
  • SORTSCHEME=1 - this is the only valid value for the environment variable. See SORTSPACE for more information.
SORTSPACE
The amount of memory to be allocated to internal workspace for SORT operations. This can be specified in different formats: for example, you could specify 64M, 2G, and 1000000 to give sort memory areas of 64 Megabytes, 2 Gigabytes and 1000000 bytes respectively.

Syntax

SET SORTSPACE=n[K|k|M|m|G|g]

Parameters

n[K|k|M|m|G|g The amount of memory to be allocated to internal workspace for SORT operations. K or k indicates kilobytes, M or m indicates megabytes and G or g indicates gigabytes. No letter indicates bytes. Defaults to 1 megabyte.

Comments

A larger value for SORTSPACE will generally result in a faster sort. However, if you specify a value that exceeds the capacity of main memory in your computer, such that the operating system has to page memory in and out, performance will be degraded.

Example

SET SORTSPACE=1024K

SORTTEMPSPACE
Specifies the amount of memory to be allocated to temporary workspace for SORT operations.

Syntax

SET SORTTEMPSPACE=n[K|k|M|m|G|g]

Parameters

n[K|k|M|m|G|g] The amount of memory to be allocated to temporary workspace for SORT operations. K or k indicates kilobytes, M or m indicates megabytes and G or g indicates gigabytes. No letter indicates bytes. 32 megabytes is the lowest amount of memory that can be allocated.

Comments

The memory allocation strategy used by SORT can be adjusted through use of SORTTEMPSPACE, which generally improves performance in systems suffering from memory fragmentation.

Example

SET SORTTEMPSPACE=250MB
SORTTYPE
Defines the sort type.

Syntax

SET SORTTYPE=2
Values
  • SORTTYPE=2 Forces SORT to use the file handler, so that format modifications are picked up from the extfh.cfg file.
  • Not setting this variable means that SORT will try to use CBL_ routines to read and write files to improve performance.
Note: 2 is the only valid value for this environment variable.
SSLDIR
If using SSL connections, this value specifies the generic location of the system's OpenSSL directory.
STEPLIB
The paths for Loader input load-members .390 files (must contain SYSLMOD) .
Note: For this environment, you can specify multiple paths, each separated by a semicolon.

T

The location of Micro Focus VSAM files.
TXMAPP
The location of the BMS load module.
TXRDTP
The location of MSS resource definition (RDO) files.
TXTRANP
The location of the CICS application object files.

V

VSE_STARTUP_CFG
The location of the VSE JCL configuration file

X

XFHLOG
Determines the location of the log file when the LOG option is active.

Syntax:

SET XFHLOG=DEFAULT

Parameters:

DEFAULT - generates the log file in the current directory.

Comments:

If the XFHLOG variable is not set, the log file is created in C:\ProgramData\Micro Focus\Enterprise Developer\[version-number].

The effect of this variable can be overridden by the LOGFILENAME configuration option.
