DRA tracing

Tracing (logging) of activity does not occur in the DRA, but there is tracing in IMS DB of DL/I and Fast Path activity. The setup and invocation of DL/I tracing for IMS DB is the same as for IMS. The output trace records for CCTL threads contain the recovery token.

Fast Path tracing in IMS DB is different from IMS. Fast Path tracing in IMS DB is activated when a SCHED request to the DRA has the PAPLFTRD equal to ON (Fast Path trace desired for this UOR).

When this UOR completes, a trace output file is closed and sent to SYSOUT Class A.

If a thread request fails during Fast Path processing, the DRA might return the PAPL with the PAPLFTRR field equal to ON. This recommends to the CCTL that it request the PAPLFTRD field be equal to ON (Fast Path trace desired) in the SCHED PAPL if this failing transaction is run again by the CCTL.
