Hi All,

I am reading the records from the VSAM file in CICS program with update option.

First read record will be locked because of update option used. When second record read will the lock on the first record will be removed or not?

Regards

If you do not update the record, release the lock by issuing an UNLOCK. Any other behavior will, sooner or later, cause program abends, anguish, wailing, gnashing of teeth, and so forth. Attempting to lock a second record in a file without unlocking the first can result in anything from a non-zero response code to a completely frozen CICS region that requires bringing the region down and back up to fix.
