Difference between TSQ and TDQ in CICS

Temporary Storage Queue (TSQ) and Transient Data Queue (TDQ) are both types of queues used in CICS for temporary data storage. Here are the key differences between them:

• Scope: TSQ is specific to a CICS transaction and exists only for the duration of that transaction. TDQ, on the other hand, can be accessed by multiple transactions.
• Lifetime: TSQ data is retained until explicitly deleted or the transaction ends, while TDQ data is automatically deleted after being read.
• Persistence: TSQ data persists across multiple program executions within the same transaction, whereas TDQ data is transient and does not persist beyond the current transaction.

Understanding the differences between TSQ and TDQ in CICS can help you effectively manage data storage and retrieval in your CICS applications.
