Enterprise Server Communications Environment Variables

Environment variables for configuring the input and output and the display.
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

CCITCP2=hostname
export CCITCP2

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

CCITCP2_PORT=port
export CCITCP2_PORT
Parameters
  • port The port on which the CCITCP2 registration program operates.
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.

ES_CAS_API
Indicates whether casout or cassub has been executed by a call and not from the command line.
ES_CONSOLE_LOG
Sends console messages to the Windows Event Log.
ES_CSKL_NO_MSG_CONSOLE
Stops CSKL writing messages to console.log.
ES_ESMAC_DISP_MAX_OVERRIDE
The number of items displayed in the ESMAC catalog view.
ES_LEGACY_ECI
Indicates that Enterprise Server must use Micro Focus ECI instead of IBM CTG.
ES_MAX_CATALOG_LINES
Restricts the number of entries displayed in ESMAC catalog view, and the default is 5000.
ES_MEM_STRATEGY
Selects the types of memory processes supported.
ES_OTMA_TIMEOUT
The time that an OTMA client should wait for an answer.
ES_SEP_DORMANT_TIME
Allows override of Transient SEP dormant time.
ES_SERVER
Server name (used if no -r switch is specified on casstart or casstop).
ES_SYSOUT_HOLD
The status of the SYSOUT files are set to Out Hold.
ES_TN3270_FORCE_ALT
Enables you to use a screen size other than the default when using a TN3270 terminal emulator.
ES_TN3270_MODEL_LOG
Writes the TN3270 emulator's model name to a temporary storage queue named TN32MODL that can be viewed using the CEBR transaction.
ES_USR_DFLT_CICS
Allows you to override the default user when no user is logged on for CICS authentication.
ES_USR_DFLT_ESMAC
Allows you to override the default user when no user is logged on for ESMAC authentication.
ES_USR_DFLT_JES
Allows you to override the default user when no user is logged on for JES authentication.
ES_ESM_DISABLE_DFLTUSER_ESMAC
Allows you to disable the default ESMAC user in order to increase the security of your server. Disables the DEFAULT button on the logon screen and forces users to always enter a valid userid and password.
ES_WS_RUNAWAY_TIMEOUT
Time in seconds that the client will wait for a response from the web service. Valid values are 0 to 65535 seconds.
IMSCPY
The location of copybook files for the DBDGEN, MFSGEN, and PSBGEN utilities.
ISPPROF
The location of ISPF dialog profiles.
JAVA_HOME
Specifies the location of the JDK.
LANG
Specifies the locale.

Syntax

LANG=language[_territory[.codepage]]
export LANG
Parameters
  • language The language in which your program is to run.
  • _ (underscore) The delimiter for language and territory, if territory is specified.
  • territory The country in which your program is to run.
  • . (period) The delimiter for territory and codepage, if codepage is specified.
  • codepage The character set to use for your program.

Example

LANG=fr_FR
export LANG
LINES
Specifies the depth of the terminal screen or window, overriding the specified terminal default.

Syntax

LINES=n
export LINES

Parameters

n The depth of the terminal screen or window, in lines.

Comments

The default, when LINES is unset or null, is to use the lines value as defined in the specified terminal's terminfo entry, or the current depth of the terminal window if you are using X windows. The terminal type is specified via the standard UNIX environment variable, TERM.

On non-windowing environments, where the terminal screen area cannot be resized, the LINES values does not need to be set.

In windowing environments, where the size of windows can be changed, the initial size of the window is used in preference to the lines value in terminfo. When the window is resized, the new size is reread. If the new size is greater than the initial size then the extra lines might not be used.

If you want to use the full depth of the window you might need to set LINES to the current depth of the window on some platforms.

Using LINES values that do not correspond to the actual depth of the window produces unexpected results.

Example

LINES=50
export LINES
LD_LIBRARY_PATH

Specifies the directory or directories for the UNIX system, Cob and the run-time system to search for shared libraries and callable shared objects. It must be set to include $COBDIR/lib on all platforms, except AIX (which uses LIBPATH). It should also include any directories that contain callable shared objects used by your application.

Syntax

LD_LIBRARY_PATH=pathname[:pathname]...
export LD_LIBRARY_PATH
Parameters

pathname A path or a list of paths, each separated by a colon (:).

Comments

The list of directories must include $COBDIR/lib. The COBDIR environment variable is described earlier.

This environment variable is a system environment variable; see your UNIX documentation for more information.

Example

LD_LIBRARY_PATH=$COBDIR/lib:/home/mydir/myapp:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH
LIBPATH
Specifies the directory or directories for the UNIX system, Cob and the runtime system to search for shared libraries and callable shared objects. It is only available on AIX-based systems and must be set to include $COBDIR/lib. It should also include any directories that contain callable shared objects used by your application.

Syntax

LIBPATH=pathname[:pathname]...
export LIBPATH

Parameters

pathname A directory to search for shared libraries.

Example

LIBPATH=$COBDIR/lib:/lib:/usr/lib
MAINFRAME_FLOATING_POINT
Specifies the format to use for floating point data items. Possible formats are IBM hexadecimal and IEEE.

Syntax

MAINFRAME_FLOATING_POINT=fpstatus
export MAINFRAME_FLOATING_POINT

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_AMODE31ONLY
Indicates that all programs are AMODE(31).
MF_CHARSET
Specifies the system character set (ASCII or EBCDIC).
MF_USESCA5
Specifies that the server should use version 5 of the Open Service Component Architecture.
Values:
  • ON (Default)
  • OFF
MFCODESET
Specifies which translation tables to use.
Values
  • A pre-defined country code:
    Important: To specify a Euro codeset, meaning that it includes the Euro symbol (€), prefix an "E" to the appropriate country code listed below. A country code with no "E" prefix indicates a non-Euro code.

MFCSCFG
Specifies a configuration file to be used by the Client/Server Binding client program.

Syntax

MFCSCFG=filename
export MFCSCFG

Parameters

filename The name of the configuration file.

Example

MFCSCFG=/home/mydir/mfclisrv.cfg
export MFCSCFG

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.

MFEXTMAP
Location of a mapper file.
MFLOGDIR
Specifies a directory to be used by Client/Server Binding for log files.

Syntax

MFLOGDIR=dirname
export MFLOGDIR

Parameters

dirname The name of the directory for log files.

Example

MFLOGDIR=/home/mydir/logs
export MFLOGDIR
MFLECONFIG

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

Syntax

MFLECONFIG=filename
export MFLECONFIG

Parameters

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

MFPRELOAD_USE
Calls MFPRELOAD to improve perfomance.
MFSUB
Specifies whether to use SUBI or ASUBI.
MFSYSCATDIR
The location of the system catalog directory.
MFUSER
Default user ID.
MFUSERCAT_LOC
The fully-qualified name of the SMS dataset.
MQSERVER
The location of an WebSphere MQ Server installation.
MULTMFENTMAP
Specifies whether special characters such as < and & are replaced with the equivalent HTML entities (for example &lt; and &amp;).
OOSW
OO run-time switches.
PATH

Specifies the directories to be searched by all UNIX programs, including the runtime system, when finding executables to be run.

Syntax

PATH=pathname[:pathname]...
export PATH

Parameters

pathname A directory to search for executables.

Example

PATH=$COBDIR/bin:$PATH
export PATH
TERM
Defines the type of terminal being used.

Syntax

TERM=name
export TERM

Parameters

name The name of the terminal in the terminfo database.

Example

TERM=at386
export TERM
TERMINFO

Specifies the directory to be searched by all UNIX programs, including the runtime system, for the UNIX system terminfo database.

Syntax

TERMINFO=pathname
export TERMINFO

Parameters

pathname The name of a directory that contains the UNIX system terminfo database.

Comments

The UNIX system terminfo database is used by all UNIX applications that need to use a terminal. However, COBOL applications tend to make much fuller and sophisticated use of the terminal and require a fuller terminfo description than is required by typical UNIX applications such as vi. Some terminal capabilities, such as those set during the initialization of the terminal to control the use of function keys, commonly conflict with the needs of typical COBOL applications. In such cases, the terminal information required by COBOL can be stored in a separate terminfo database and referenced using COBTERMINFO.

TMPDIR
Specifies a directory in which to store temporary files in place of the UNIX system default.

Syntax

TMPDIR=pathname
export TMPDIR

Parameters

pathname The directory used by UNIX applications for any temporary work files. Temporary work files can be created by COBOL utilities such as Cob or by the runtime system when it executes statements such as SORT. If you do not specify a directory, the system default directory is used.

Comments

You might need to use this environment variable if the runtime system needs to page data to disk when creating heaps or sorting.

TX_TN3270_FORCE_ALT
Enables you to use a screen size other than the default when using a TN3270 terminal emulator.
TXMAPP
The location of the BMS load module.
TXRDTP
The location of MSS resource definition (RDO) files.
USER
Default user name.
