Capture the CICS Internal Trace Table

With CA SymDump for CICS, you can capture and review the CICS Internal Trace Table at any time. The CA SymDump for CICS online formatted trace utility captures an image of the CICS Internal Trace Table, and can replace the AUX TRACE facility for debugging system performance problems in many cases.

Before you capture and review your trace, complete the following:

1. Ensure that you have sufficient space on your PROTDMP file. The larger the CICS Internal Trace Table, the more space you need.
2. Expand your extended DSA allocation to accommodate the size of the trace you will review. You will need additional DSA of approximately twice the size of the CICS Internal Trace Table for each trace being viewed.
3. Expand the size of your CICS Internal Trace Table so you will not lose entries you may be trying to capture when the table wraps. To do this, use the CICS CETR transaction or modify the size of the CICS Internal Trace Table using the SIT TRTABSZ parameter.

Once you complete these steps, execute the transaction you want to trace. When you reach a point where enough trace entries exist, you have two methods available for capturing the trace with CA SymDump for CICS.
