nfs - What are the implications of using NFS3 file system for multi-instance queue managers in WebSphere MQ -

we stuck in hard scenario in our new mq infrastructure implementation using multi-instance queue managers using websphere mq v7.5 in linux platform. concern our network team not able configure nfs4 , hence still having nfs3 version. understand multi-instance queue managers not function nfs3. there issues if define queue managers in multi-instance fashion in nfs3 , expect work perfect single instance mode.

thanks

i not expect have issues running single-node queue managers nfs3, on regular basis. requirement nfs4 file locking mechanism required multi-instance queue managers determine when primary instance has lost command , secondary queue manager should take over.

if define queue manager multi-instance, , queue manager effort failover, may not successfully, @ worst may corrupt queue manager files.

if command failover - in, shutdown queue manager on 1 node , start 1 time again on node - should work you, there no file sharing taking place , files shutdown on primary node before beingness opened on secondary node. have create sure secondary queue manager not running in standby node -- ever.

i hope helps.
