Abstract
IBM MQ Multi-instance queue manager setup in Linux using NFS
Content
This documentation has the steps for setting up and verifying the IBM MQ multi-instance queue manager in Linux.
The setup is small to illustrate the concepts involved.
.
Multi-instance queue manager means the instances of the same queue manager configured on two or more computers.
Multi-instance queue managers and HA clusters are alternative ways to achieve high availability for your queue managers.
By starting multiple instances, one instance becomes the active instance and the other instances become standbys.
If the active instance fails, a standby instance running on a different computer automatically takes over.
.
You can use multi-instance queue managers to configure your own highly available messaging systems based on IBM MQ, without requiring a cluster technology such as HACMP or MSCS. HA clusters and multi-instance queue managers are alternative ways of making queue managers highly available. Do not combine them by putting a multi-instance queue manager in an HA cluster.
Multi-instance queue managers include the following two main features:
- Basic failover support integrated into IBM MQ
- Faster failover than HA cluster
