DFS4453I LTERM MSGQ|EMHQ MESSAGES UNLOCKED FOR xxxx
Explanation
When an IMS terminates abnormally in an IMSplex environment, the LTERM messages that were locked from the MSGQ or EMHQ structures must be unlocked so that they can be made available to terminals or users accessing another IMS system in the IMSplex. The surviving IMS in the IMSplex unlocks the messages with cleaning up resources. In addition, when a restarting IMS connects with CQS, it unlocks any remaining messages, which also results in appropriate CQS cleanup.
The message text indicates which messages were unlocked, MSGQ or EMHQ. The variable xxxx indicates the system for which messages were unlocked.
System action
When the unlock process is performed by a different IMS, the unlocking is performed asynchronously and normal online processing continues. When the unlock process is performed by the restarting IMS, normal restart resumes after unlocking is complete.
