Hi ,
I am having a problem with my production Broker on clustered servers,
Yesterday when i checked it appears to be running , with a ps -ef |grep [/b]bip command , and this morning when i check it appears to be stopped , and i also checked the log files , it shows that the broker was down since the 22nd April,
What i want to find out is :
is there a possibility that a ps command can be wrong in any other cases , or what could have happened
Thanking you in advance |

Clustered how? WMQ cluster? Or failover cluster?

This is an OS question, but the ps command is fairly reliable. If this is a failover cluster, you could be looking at the standby (non-running) node.

When there's nothing to write.

Then your failover script has a fault that needs fixing. The broker should be started on failover like any other software.

If it is a Sun Cluster and broker is not able to start automatically on the other node then "makgotsophemelo" need to ask Sun Team/Unix team to configure the Broker for the failover alon with MQ.
makgotsophemelo also need to ensure whether the Broker queue manager is able to failover successfully on the other node in case of failure?
If queue manager is not able to failover on other node then this is the problem due to wong failover cluster setup of MQ.
[makgotsophemelo write] i also checked the log files , it shows that the broker was down since the 22nd April[/makgotsophemelo write]
Which log files have you checked for Broker? Have you checked the queue manager was running on the same node or the other node?
Best Regarrds,
