Hi there,

Currently we are on the middle of migrating from Power with AIX to x86 with RHEL for client entire SOA Architecture (MQ, ACE, BAW, ITX, and WSRR).

Previously on AIX in order to connect to the Database and the other server, they didn't use DNS and use hostname that they defined on /etc/hosts file. With that in mind, they create their hostname with format soa.xxy where xx is the target of server (ps for WPS, mb for WMB, etc) and y as the specific server number. This hostname is the one that being used on the CONNAME of the Auto-Defined Cluster Channel.

But, when we are moving to RHEL, our client planned to add RAC to their Database system and need to add the DNS on the OS level. Because of this, the previous format causing the OS level to think the hostname as fdqn and it will take longer for the channel to connect (From INACTIVE to STARTED). Initially, they want to have the same as the one on Power Machine, but the RAC of their Database is the requirement long after the initial plan. Because of this, the client change the hostname to soaxxy, where they takes out the '.' character. With that change, we need to to update the CONNAME of the Auto-Defined Cluster Channel and all of our other channels.

Is it possible to update the CONNAME on the Auto-Defined Cluster Channel? If it's possible, is there any step and documentation that we could follow to update the CONNAME?

Thank you

Hello Gregorius,

You might remember that in the cluster the auto-defined sender channel is based on the cluster receiver channel. So if you update the conname in the cluster receiver channel, it will update it in the auto-defined sender channel.

Remember the correct sequence to update a cluster receiver channel: 

1. remove cluster attribute
2. update the conname
3. set cluster attribute

Have fun

As the change happens, ensure the Channels state returns to RUNNING; else some where int he cluster it would be in RETRY causing unwanted headache.
