In order to support execution of multiple archive subtasks and provide the ability to keep CA Dispatch and its subtasks active 24x7 while still being able to perform daily maintenance, there was a functional change made in the CA Dispatch code that excludes entries on the CURRENTLY ACTIVE ARCHIVE VOLSER from being considered for deletion.
Once the volser is no longer the currently active archive volser, all entries that reside on this volser and that have exceeded their retentions will be deleted during the next execution of the batch archive cleanup maintenance process.
The ACTIVE ARCHIVE VOLSER is displayed on the VSGMU210 screen (option 9.A from the main menu) next to the "Tape ==>" field.
Dispatch will write to the currently active archive volser until either it becomes full and switches to a new SCRATCH volser. Or, the CLEAR command is executed to free the active volser.
