DRA snap data set

The DRA’s snap data set is dynamically allocated to the CICS® address space when DBCTL is connected.

The SYSOUT class used is determined by a parameter in the DRA startup table. The DRA dumps its control blocks (those associated with its own work unit and that of DBCTL) to this data set whenever a high order bit is set in PAPLRETC. (The participant adapter parameter list (PAPL) is a part of the DRA. For guidance on the PAPL and its contents, see the appropriate Exit routines in IMS product documentation.) The high order bit is set on if a thread is terminating. It then closes the snap file. The recovery token appears in the dump produced.
