UIEFRDER


1  UIEFRDER
1! Y
1 N
UIEFRDER
Specifies whether FM/IMS batch functions which are using PSBs that have update intent, use the IEFRDER DD specified in the JCL when they are run in DLI mode.
Y
Use the IEFRDER DD.
N
Do not use the IEFRDER DD.

If you specify UIEFRDER=N, then batch functions which are using PSBs that have update intent:

  • Check whether the IEFRDER DD was allocated by the job step and, if it was, frees this allocation.
  • Dynamically allocates an IEFRDER DD according to the LOG parameters specified in the FMNIMSIN input (when the parameters are specified and are not fixed) or the subsystem defaults for the LOG parameters (otherwise).

If you specify UIEFRDER=Y, then batch functions which are using PSBs that have update intent use the IEFRDER DD allocated by the job step (when the IEFRDER DD is allocated) or dynamically allocate an IEFRDER DD according to the LOG parameters specified in the FMNIMSIN input (when the parameters are specified and are not fixed) or the subsystem defaults for the LOG parameters (otherwise).

This parameter is optional. If it is not specified on the FMN1POPI macro statement, FM/IMS uses either the value that is specified on the FMN1POPD macro statement (if specified on that statement), or Y (otherwise).
