R12.1.3 internal concurrent manager not running (upgraded from 11.5.10.2)

Question

I have an instance that I have upgraded from 11.5.10.2 --> 12.1.1 --> 12.1.3 (db is 10.2.0.4)
oldservername CRMTESTAPP (still machine name)
newservername CRMR12 (alias in DNS and hosts to same machine)
After doing the upgrade I ran into an issue where the hostname.domainname was 31 characters long, which created an issue trying to start the ICM due to column limits in FND_CONCURRENT_PROCESSES (doc 413164.1)
We created an alias to the server that was shorter and I ran the adcfgclone to configure the instance with the new server name.
Everything ran, completed and the ICM will still not start. It seems to be looking for the FNDFS_oldservername instead of using the newservername
in FND_NODES only the newservername and authentication are listed. I shut everything down, ran cmclean.sql and I have also tried the CM Recovery wizard.
In OAM when you click the ICM, and click Edit it shows the newservername as the only node listed, yet still when you click Log you get:
"An error occurred while attempting to establish an Applications File Server connection with the node FNDFS_CRMTESTAPP. There may be a network configuration problem, or the TNS listener on node FNDFS_CRMTESTAPP may not be running. Please contact your system administrator."
Also when I click Internal Manager, then click the Environment button it seems to be referencing the old 11.5.10 install directories instead of the new ones.
How can I define which server the instance needs to use other than the methods I have tried?
Thanks

Answer 1

None of the env files reference the old host
What about other CMs?
All are defined as the correct node
Can you find any errors in the CM log file?
None other than the 30 chararcter limit error.
If the internal manager shows the correct hostname, then you should find it in the table. For now, take a backup of this table, and update the target_node column for all CMs and try again.
I have updated the table, however it doesn't make a difference because none of the other CM will run without the ICM running according to their diagnostic logs.
I was looking through document 413164.1 and noticed it said that hostname / domainname has to be less than 30 characters. Is this to say hostname has to be less than 30 AND domainname has to be less than 30 OR hostname.domainname together have to be less than 30?
I also looked on our current 11.5.10.2 instance which has the same 30 character limit on the node_name column in fnd_concurrent_queues and it only populates with hostname. Which I assume is what R12 would do as well, which means I am well under the 30 character limit for just node_name.
Is there something I can trace to see what the insert statement is trying to put into the node_name column? The ICM according to OAM is still configured to point to the old 11.5.10 home as opposed to the new 12 home? Autoconfig files have nothing to reference the old home that I have found, where does the ICM pull the environment settings from?
Thanks again
