Before introduction of MQ Appliance version 9.0.1, it was required to manually start all queue managers which are not configured for high availability after every restart of appliance. Although restart of appliance is deemed a rare operation on a production running system, it still required an intervention of administrators to bring queue managers back to running. This might be a small inconvenience for some users, or something more important in cases when system must get up and running as quick as possible after planned or unplanned reboot. And so, the 9.0.1 version introduces the fix, allowing to configure queue managers to start automatically on system start-up.
Configuring queue manager for auto start
The initial configuration of the auto-start option is done when creating queue manager using the new -sa option:
Editing auto-start option
Changing auto-start option of a queue manager is performed by setting Startup key in its configuration value, which is done using setmqini command. The key can be set either to Automatic or Manual value to switch the auto-start option On or Off.
Checking auto-start option
To check current configuration of the auto-start option the dspmqini command can be used, which displays different configuration values of a queue manager. For example, the command below displays the value of the Startup key:
High availability queue managers
Unlike traditional queue managers, high availability queue managers always start during system start-up or after being created. Checking their Startup key provides a different value:
Being a small feature, the auto-start option becomes handy when performing MQ appliance maintenance tasks involving system restart. Administrators no longer need to worry about bringing the system to the up and running state.
