Trace information

CICS® VR maintains an internal trace table to help you follow the order in which the CICS® VR modules are invoked before an abend.

The trace is wraparound, with this end mark after the last trace entry:
   ****************
Each entry consists of these two 8-byte character strings:
  • Module name field
  • Reason field

A trace entry with reason PROLOG is added on entry to the module. An entry with reason EPILOG® is added at exit from the module.

When the dump is online in machine-readable format, you find the trace table by scanning the dump and searching for one of these fields:
  • ****************
  • PROLOG
  • EPILOG®

Alternatively, you find the address of the trace table, and its end mark, in the BIB block of CICS® VR. You find the address of the trace table at offset X'440' in the BIB, and the address of the end-of-trace mark at offset X'448'.
