TEMPORARY STORAGE TABLE (TST)
The temporary storage table (TST) is a list of generic mnemonics
used:
1. To identify temporary storage DATAIDs for which CICS is to
provide recoverability in the event of abnormal termination
of CICS and subsequent emergency restart.
2. To identify DATAIDs for which security checking is to be
performed.
3. To identify DATAIDs on a remote system.
4. To map selected remote system SYSIDs to shared queue pools.
Each recovery entry in the table specifies the leading characters
of user-defined DATAIDs for which CICS will provide protection
(enqueueing) during a logical unit of work by an application
program and automatic logging of the status of the data at task
termination (or sync point). CSATSTBA in the CSA optional
features list (CSAOPFL) points to the temporary storage table
(TST).
