Hi All,

Can anyone can tell when the CICS read random is done to the VSAM file with required key,does CICS go to buffer allocated in CICS for the VSAM file to check if the requested record present or not? Or it directly go to the file to retrieve the record.

Thanks,
bnsahoo

The whole point of LSR processing is to keep the frequently referenced records in buffers in memory to prevent CICS from having to go to the file to retrieve a record.
