Answer:
This occurs when a programmer Issues a EXEC CICS Syncpoint command. this is called two phase because CICS will first commit changes to the resources under its control like VSAM files, and the DB2 changes are committed. Usually CICS signal DB2 to complete the next phase and release all the locks.
