Running in the OPM Default Activation Group

When an IBM® i job is started, the system creates an activation group to be used by OPM programs. The symbol used to represent this activation group is *DFTACTGRP. You cannot delete the OPM default activation group. It is deleted by the system when your job ends.

OPM programs automatically run in the OPM default activation group. An ILE program will also run in the OPM default activation group when one of the following occurs:
  • The program was created with DFTACTGRP(*YES) on the CRTBNDRPG command.
  • The program was created with ACTGRP(*CALLER) at the time of program creation and the caller of the program runs in the default activation group. Note that you can only specify ACTGRP(*CALLER) on the CRTBNDRPG command if DFTACTGRP(*NO) is also specified.
Note: The resources associated with a program running in the OPM default activation group via *CALLER will not be deleted until the job ends.
