In an on-line environment, how can you prevent more than one user from accessing the same Transient Data Queue at the same time?
technology mainframe

  1. By issuing an EXEC CICS ENQ against the resource.

  2. By issuing an EXEC CICS EQN against the resource.

  3. By issuing an EXEC CICS DEQ against the resource.

  4. By issuing an EXEC CICS DQE against the resource.

  5. By issuing an EXEC CICS TDQ against the resource.

Show answer
Correct Option: A
Explanation:

To answer this question, the user needs to know about Transient Data Queues (TDQs) and how to prevent multiple users from accessing the same TDQ at the same time.

Option A: By issuing an EXEC CICS ENQ against the resource. This option is correct because an ENQ command is used to obtain a lock on a resource, such as a TDQ, to prevent other transactions from accessing it simultaneously. By issuing an ENQ command against the TDQ, a lock is obtained, and other transactions are blocked from accessing the same TDQ until the lock is released with a DEQ command.

Option B: By issuing an EXEC CICS EQN against the resource. This option is incorrect because there is no such command as EQN in CICS.

Option C: By issuing an EXEC CICS DEQ against the resource. This option is partially correct because a DEQ command is used to release a lock on a resource, such as a TDQ, after it has been obtained with an ENQ command. However, it does not prevent multiple users from accessing the same TDQ at the same time.

Option D: By issuing an EXEC CICS DQE against the resource. This option is incorrect because there is no such command as DQE in CICS.

Option E: By issuing an EXEC CICS TDQ against the resource. This option is incorrect because a TDQ command is used to read from or write to a TDQ, but it does not prevent multiple users from accessing the same TDQ at the same time.

Therefore, the correct answer is:

The Answer is: A. By issuing an EXEC CICS ENQ against the resource.
