What is the difference between a transient and a temporary data queue in CICS?

Transient Data Queue:

• A transient data queue exists only during the CICS transaction execution and is automatically deleted when the transaction ends.
• It is useful for temporary data storage within a single transaction and is not persistent across multiple transactions.

Temporary Data Queue:

• A temporary data queue is a more persistent storage mechanism that persists beyond a single transaction in CICS.
• Data stored in a temporary data queue remains accessible even after the transaction that created it has ended.

Summary:

The main difference between a transient and a temporary data queue in CICS is the persistence of the data. Transient data queues are temporary and exist only during the transaction execution, while temporary data queues are more permanent and persist beyond a single transaction.
