Question
Command used to release the queues after IPL is:
A. $HQ,ALL
B. $AA,ALL
C. $HA,ALL
D. $AQ,ALL
Answer
D. $AQ,ALL
Explanation
After an Initial Program Load (IPL) on a mainframe system, the $AQ,ALL command is used to release all the queues. This is the correct answer among the options provided.
The $AQ,ALL command is a JES2 command that releases all the jobs in the queues, allowing them to be processed. When a mainframe system undergoes an IPL, the queues are initially held to prevent jobs from starting prematurely before the system is fully initialized and stable. Once the IPL is complete and the system is ready, the $AQ,ALL command is issued to release the queues and allow normal job processing to resume.
The other options mentioned are incorrect:
- $HQ,ALL is not a valid JES2 command
- $AA,ALL is not related to releasing queues
- $HA,ALL is used to halt a specific address space, not release queues
In summary, $AQ,ALL is the command used to release all queues after an IPL on a mainframe system running JES2. This command is critical to resume normal batch job processing following a system restart.
