Hi,
I am doing an Active-Active HACMP setup for WMQ 6 on AIX 5.3. I am taking reference from supportpac MC91
I have two Nodes, NodeA and NodeB. Each Node has 1 Resource Group. Each resource group will have only 1 Queue Manager. The shared disks are on the SAN.
I have a few questions, can you please help?
>> Will there be two separate Shared Storages required for Active-Active configuration? one SAN storage for each Node.
>> Will there be different mount points of the Shared Disks from each Node?
>> if there are different mount points, how will the halinkmqm command work when run from the takeover node?
Say, for instance, I have created a Queue Manager ha.csq1 on NodeA, the filesystem for data on the SAN being /MQHA/ha.csq1/data
Now, i have to run the halinkmqm from the takeover Node, NodeB
I understand that the command will be something like this
$halinkmqm ha.csq1 ha!csq1 /MQHA/ha.csq1/data
here /MQHA/ha.csq1/data is the filesystem in the SAN for Queue Manager's data in the NodeA. How can we access this filesystem (mounted on NodeA) from NodeB if the mount points are different.
addtionally, What changes have to be done to the start and stop script (provided with MC91) in order to make it work for active-active set-up
Can you please help?
Thank You And Merry Christmas |
