installation of MQ for VCS active/standby setup
I am settting up an active/standby MQ cluster in an AIX environement. Do I have to install the MQ binary on both nodes? Also seems MQ is an package, I can't seem to install just once for the 2 nodes. If I do so, that other node will have no MQ package information from lslpp. Or it does not matter?
Thanks!

- If MQ needs to be installed as a package to run on the system, then the binaries/packages need to be installed on both cluster nodes.
As you already mentioned, if MQ is only installed on one system, if you go to failover to the standby system later, it won't have any binaries/package information so won't be able to run (similar to if you attempted to run MQ on a standalone node that hadn't had MQ installed!)
If you were talking about something simple such as a shell script that didn't have dependencies, then it would be sufficient to locate this on shared storage that failed over between each node; however as MQ does have package dependences, the binaries do need to be installed on both/all cluster nodes where it needs to run.
