Design overview

To provide corrective action in response to a programming error, you can code a program error program (DFHPEP). This program can then be assembled and link-edited to replace the dummy DFHPEP.

If provided, this program is invoked by the abnormal condition program (DFHACP) whenever a task terminates due to a task abnormal condition. However, it will NOT be called if a task is terminated due to an attach failure (for example the transaction is not defined) or when CICS® deliberately terminates a task to alleviate a stall.

The user can perform any kind of corrective action within a program error program.

Guidance information about PEP coding is given in the CICS Recovery and Restart Guide. Reference information about PEP coding is given in the CICS Customization Guide.
