Mainframe Access Environment Variables

These environment variables relate to the Mainframe Access functionality.

AUTOCAT_IMP
Name of an input file name for automated catalog import using MFA Data Access Services.
Values
  • An input file path and name.
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 default is 2 minutes (1200), and the maximum value that can be used is 2,147,483,647.

Example for setting this value to 4 minutes:
SET CCITIMEOUT=2400 
COBCPY
Specifies the directory or directories that the Compiler and Animator should search for copyfiles.
Values
  • A list of search directories, each item separated by a semicolon.
DBG_MVSPSKEL
The skeleton JCL for debugging
ENTRYNAMEMAP
Location of the mfentmap.dat entry name map file.
Values
  • File path and name of the mfentmap.dat entry name map file.
GDG.RECALL
Controls the recall of HSM archived datasets when accessing mainframe GDGs using MFA Data Access Services.
HELP
The location of IBM PL/I help files
HOST_DISP
Determines whether JCL DISP will be honored for DELETE on mainframe resident datasets.
HOST_NEW
Determines whether JCL looks on the host for new datasets that are not cataloged locally.
MF_SET_USERID
Sets the default user ID.
MAINFRAME_FLOATING_POINT
Specifies the format to use for floating point data items.
Values
  • 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.
Note:
  • 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.
MFACLIENTINI
The complete path to the INI file containing mainframe logon credentials, which defaults to:

c:\users\USERNAME\appdata\roaming\micro focus\mfaclient.ini

MFAIMBEDDEDHEX
Indicates that you wish to have all source code embedded hex values handled in the same way as the MDECONV application, in that all translated hex values less than x'1f' will have a null character inserted before the hex value. The COBOL run-time system will properly handle these imbedded hex values. Example:
SET MFAIMBEDDEDHEX=COBOL
MFAMAXHOTLINKS
If using the hot-link software from Micro Focus, the LSC applications will route all communication request through this hot-link. The hot-link remains active to the mainframe until you shut down your workstation, or enter the command MFDAELSC CLOSE. The hot-link is able to allocate and load balance more than multiple simultaneous links and will start up an additional link if any request has to wait for more than 15 seconds for a time slice. The maximum number of simultaneous links can be specified, with a default of 4 and a maximum of 10, as follows:
SET MFAMAXHOTLINKS=4
MFAMAXSENDLENGTH
Sets the maximum length of data, in a single communication packet, that can be transmitted to or from the mainframe. This does not affect the size of the file that can be transmitted, but only the size of each of the numerous data chunks that are transmitted to make up the entire file. This is only useful, when there is a router that limits the transfer length of data to or from the mainframe, or there is a restriction in the length of data that can be transferred. Example:
SET MFAMAXSENDLENGTH=4000
MFASERV
Controls how mainframe access checks for a dataset name (DSN):
  • ON

    If a DSN is not found in the local catalog, then the catalog API calls MFA to check the mainframe for the DSN.

  • Not set

    The catalog API does not call MFA to check the mainframe for the DSN.

MFE.FALLTHRUCHECK
Enables messages to be issued if the user program does not return from a main program via GOBAK or STOP RUN.
MFUSERCAT_NODE
User catalog node
MVSCATIO_TIMEOUT
Time allowed for a catalog input/output operation to complete
NEWJCL
Controls ISPF skeleton JCL processing
SHOW_CATALOG_WAIT
Displays a message when the enterprise server is waiting for a response from the catalog server.
