The features of the SQL Memory Guard can be activated or deactivated, though normally only at the direction of CA Support, by executing the following commands (for more information on DIAGOPTION, see the CA Datacom/DB Database and System Administration Guide):
Causes automatic debugging and abend prevention to begin either immediately or as soon as the trace table is allocated.
Causes automatic debugging and abend prevention to stop. If the trace table has been allocated, requests are still logged.
Causes the memory trace table to be allocated (approximately 32K) and activated (meaning memory requests are logged) when the next new RUN UNIT starts its first SQL request. In order to receive automatic debugging and abend prevention, also execute DIAGOPTION 2,2,ON as described in the following related section.
Causes the memory trace table to be freed (the memory manager makes the storage available for use by SQL only) when the next new RUN UNIT starts its first SQL request.
