Syncpoints in z/OS batch applications

 

For batch applications, we can use the WebSphere MQ syncpoint management calls: MQCMIT and MQBACK. For backward compatibility, CSQBCMT and CSQBBAK are available as synonyms.

If we need to commit or back out updates to resources managed by different resource managers, such as WebSphere MQ and DB2, within a single unit of work we can use RRS. For further information see Transaction management and recoverable resource manager services.
