Hi!

I need to use an MQseries in two Unix machines (Main and Standby). Both are linked to an external storage. Question? What is enough to make MQseries avaliable on these enviromment? May I mount storage on /var/mqm mount point?

Both machines will run exclusive-mode, so storage will be accessed only for one machine in same time. This will prevent of lock files or strange behavior, but if one machine stops responding, the MQSeries files will be usable in another node, or another machine will believe that MQ files are corrupted for any reason?

Regard´s

See MC91 for the supported HA/failover configurations. The requirement that MUST be fulfilled is that only one running instance of the queue manager must be allowed to access /var/mqm at any one time. If two running instances read/write the data at the same time - even for a moment, unintentionally - the MQ data will almost certainly become corrupted. MQ was desgined to have one running instance at any one time.
