Syncpoints in IBM MQ for z/OS applications

This topic explains how to use syncpoints in transaction manager ( CICS and IMS ) and batch applications.

• Syncpoints in CICS Transaction Server for z/OS applications
  In a CICS application you establish a syncpoint by using the EXEC CICS SYNCPOINT command.
• Syncpoints in IMS applications
  In an IMS application, establish a syncpoint by using IMS calls such as GU (get unique) to the IOPCB and CHKP (checkpoint).
• Syncpoints in z/OS batch applications
  For batch applications, we can use the IBM MQ syncpoint management calls: MQCMIT and MQBACK. For compatibility with earlier versions, CSQBCMT and CSQBBAK are available as synonyms.
