We have two machines on each one we have a queue manager.
If one machine goes down we want to start the other queue manager
in the same stat and data from the persistence logs.
It is enough to point to the same log directory?
If yes, they (queue manager) need to be in the same name?

This is a very complicated thing; failing over a queue manager across hardware. Are you using some third party failover product? Also, are you planning on failing over the IP address as well? Any channels running to the queue manager that goes down will go into retry mode unless the new machine picks up the IP. Of course, you don't have to do it this way, but not failing over the IP would require the other queue managers to know that queue manager A has gone down and failed over to queue manager B...

Please view the SupportPAC mc6a. This SupportPAC deals with failover of
MQSeries using Veritas Cluster Server. |

We use MC Service Guard, and we have a floating ip.
Machine B will have the Machine A ip as well.
The question is, if they can share the same log directory for recovery?

| installing mq on local disks on both sides and having object and log files on shared disks seems fine to me (assuming you'll only have the 1 qmgr) on either box. If you have many qmgr on both sides of pair then you need to be a little smarter with your mount points. |

Try this:

It's the Support Pac for configuring MQSeries under Service Guard.
