The system recovery table (SRT) contains a list of codes for abends that CICS® intercepts. After it intercepts one, CICS attempts to remain operational by causing the offending task to abend.
You can modify the default recovery action by writing your own recovery program. You do this by means of the XSRAB global user exit point within the System Recovery Program (SRP). (See the CICS Customization Guide for programming information about the XSRAB exit.)
Note that recovery is attempted only if a user task (not a system task) is in control at the time the abend occurs.
