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.
