CICS® VR cannot flush trace buffers in storage to the trace writer data sets. So, in addition to having trace writer data sets available, storage dumps of the CICS VR server address space and CICS VR client's address spaces are required.
If the problem being traced does not result in a dump you can use the MVS™ DUMP command to produce an SVCDUMP-type dump containing the trace buffer data. See z/OS® MVS IPCS Commands for a complete description of this service.
It is possible that, with a sufficiently large trace table (8 MB recommended, use 16 MB if possible), no data is in the trace writer data sets.
