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

In CICS, a transient data queue is a temporary storage area used for passing data between programs within the same CICS region, while a temporary data queue is a temporary storage area used for passing data between programs running in different CICS regions.

Transient data queues are specific to the local CICS region and are automatically deleted when the CICS region is shutdown or restarted. On the other hand, temporary data queues can be accessed by multiple CICS regions and are manually managed by system administrators.

It is important to understand the distinction between transient and temporary data queues in CICS to effectively manage data communication between programs within and across different CICS regions.
