Difference between Transient Data and Temporary Storage Queue in CICS

In CICS, Transient Data and Temporary Storage Queue are two different types of storage that can be used to hold temporary data. Here is the difference between the two:

Transient Data

• Transient Data is a temporary storage area that is dynamically created and maintained by CICS.
• It is typically used to hold data that is needed for a short period of time and is specific to a particular transaction or program.
• Transient Data is automatically deleted when the transaction or program that created it finishes executing.

Temporary Storage Queue

• Temporary Storage Queue is a storage area where data can be stored temporarily in a FIFO (First In, First Out) manner.
• It is typically used to pass data between different transactions or programs within CICS.
• Data stored in a Temporary Storage Queue persists until it is explicitly deleted or until the CICS region is restarted.

Overall, Transient Data is more short-lived and specific to a single transaction or program, while Temporary Storage Queue is used for passing data between different parts of the CICS system.
