Example of resource manager processing

z/OS MVS Programming: Resource Recovery
SA23-1395-00

This section gives pseudo-code examples of resource manager processing in the following topics:

The examples assume SRB exit routines; see Using resource recovery services for information about SRB routines.

These examples indicate possible processing, but the processing can be done in other ways. For instance, in the first example on restart processing:
  • Commit and backout processing are performed inline. The resource manager could specify ATR_RESPOND_CONTINUE in the Respond_to_Retrieved_Interest call and perform the commit and backout processing in the COMMIT and BACKOUT exit routines.
  • The resource manager responds to all retrieved URs after it begins to process new URs. A resource manager can, however, respond to all retrieved interests before calling the End_Restart service.

Also, the examples emphasize processing related to RRS; processing related to database management is very high level.
