Hi Rambabu,
This occurs when a programmer Issues an 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 then DB2 changes are
committed.
Usually CICS signals DB2 to complete the next phase and releases all the locks.
