Cause . . . . . : &1 activation groups were deleted. The activation groups were deleted because they were not active and the job was not in debug mode and the activation groups were not shared. Refer to the preceding messages in the job log to find which activation groups were deleted. Technical description . . . . . . . . : If an activation group could not be deleted, it is either in use, the activation group is a shared group, or Debug is active. To see which activation groups are in use, display the job's call stack (WRKJOB OPTION(*PGMSTK)). If Start Debug (STRDBG) has been called for the job, activation groups are in use although they do not appear on the call stack. If no activation groups were deleted, there were none eligible.
