Answer / anna
if we have cics/db2 programm we issue two phase commit.
cics issue syncpoint and send request to db2.
db2 prepare to commit send yes to cics.
cics prepare to commit and when cics ready
db2 commit the updates after cics commit is done.
this logic is called two phase commit.

Answer / reddy
This will happen when we are using EXEC CICS SYNCPOINT.
IT will commit all the resources(VSAM FILES, QUEUES) and DB2
changes are commited.
NOTE:
if we are not using SYNCPOINT, the DB2 changes are
commited, not VSAM,QUEUES until end of job.
