Dump Data

The Dump Data user exit, CPSU, is called by system error processing. This exit provides an interface for dumps with an associated entry control block (ECB) that will enable a user to save dump data for on-line processing. Both SERRC and SNAPC dumps are supported. Dump data will be presented to the dump data user exit. Activating the dump data user exit does not bypass normal system processing.

Programming Considerations

  1. The released version of CPSU contains sample code which will release the dump data blocks and exit the ECB.
  2. Issuing a SNAPC dump in dump data processing will cause an infinite loop. Use the appropriate tests to terminate the loop when coding a SNAPC macro.
  3. The dump data user exit cannot be controlled independently for SERRC and SNAPC.
  4. A SYSTC tag, SBDTAC, is defined for this user exit. The tag specifies whether detached data blocks are presented. If the switch is on, there are detached data blocks. The maximum number of detached blocks, including both ECB data levels and DECBs, is specified by the DETDATAX constant in CZOCP.
  5. You can use the IDECB DSECT to map the DECB frames that are presented.
