Error description
In the MQ Appliance, if there are multiple Queue Managers sharing a common suffix in their names and one of them transitions to an "ended" state, it affects other QMgrs with a similar suffix. Specifically, the HA control is disabled. Steps to recreate: 1) crtmqm -sx AAATEST 2) crtmqm -sx ATEST 3) endmqm -w AAATEST 4) status -l The result reported status is: QM(AAATEST) Status(Ended unexpectedly) Queue manager file system: 0.2GB total, 50MB used [42%] HA role: Primary HA status: Normal HA control: Disabled HA preferred location: This appliance HA blocked location: None QM(ATEST) Status(Running) CPU: 1.91% Memory: 189MB Queue manager file system: 0.2GB total, 50MB used [42%] HA role: Primary HA status: Normal HA control: Disabled HA preferred location: This appliance HA blocked location: None
Local fix
Start the queue manager that has the same suffix as the one showing HA control as disabled.
Problem summary
**************************************************************** USERS AFFECTED: MQ appliance users using High Availability queue managers with same suffix in the queue manager names Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: When a queue manager is stopped, a defect in the logic used to filter the QM names caused the HA control of a different QM with same suffix as the queue manager that was stopped, to go into disabled state.
