Hi All,

We have an issue with the Multi instance queue manager:

NFS setup is in cluster.

There is a multi-instance Queue Manager configured using NFS clusters

Whenever there is a failover in NFS1 , Queue manager is also shifting from primary to secondary server

While NFS failover, the secondary nfs(NFS2) will be active with threshold of 40sec

Can we make queue manager wait in primary server, while failover of nfsserver from NFS1 to NFS2

Thanks in advance
Any help is appreciated

MQ uses files locks to coordinate MI failover. If the NFS failover breaks that lock, which it sounds like it does, then the MI will failover.

Jeff:
Is there any parameter which we can set that will make the Queue Manager wait, let's say for a minute (60 seconds) before it fails over to the standby

That's a PMR question.
