Hi We are trying to read a VSAM RLS file in a cics region. Can we do that using partilal key? The way we want to update VSAM RLS file as well. Could you please advise what are the things to keep in mind using RLS READ UPDATE. Any documentation , links or any read update sample code will be of great help..thanks

VSAM RLS provides the record locking and buffer coherency functions across CICS and batch. But the transactional recovery function for applications is provided by CICS. CICS creates a backout log record for each change made to a recoverable file, and VSAM RLS obtains and holds a lock on each changed record. The lock remains held until the transaction ends. If a transaction fails, CICS backs out all changes made by the application to recoverable files, thus isolating the other sharing applications from the failure.

I am surprised, Why as yet none of your CICS Admin/support staff don't have answer for this? or You are the one who don't want to reach them for the answers at first place?
