Below reponse would help you understand the ERROR and its severity.
ERROR [Monitor Guaranteed Message Logger Thread] [CCM_10322] While logging messages to the Log Service, the following error occurred: [[DOM_10022] The master gateway node for the domain is not available. Electing another master gateway. Wait for the election of the master gateway node to complete. If the problem persists, verify that the master gateway node is running.]. Fix the errors written to the node.log file.
The most common causes are:
During Domain startup when services have already started while the Master Gateway election is still ongoing. In this case, the error can be safely ignored and should not occur again once the Master Gateway node has been elected.
During a failover where the Master Gateway node has just gone down and a new one has not been elected.
If another Master Gateway node can be elected in the domain, all services will automatically become available again and will resume normal operation.
In this case, the error itself can be safely ignored, although you might want to investigate the reason for the failover.
If the domain does not become available and the error continues to occur, check $INFA_HOME/tomcat/logs/node.log on all configured Gateway Nodes in this domain to identify why no Gateway could be elected. This could indicate an issue with the network or the domain database.
Thanks Yuva for the reply.
We are only a one node domain.
This does not happen during the domain start-up. All our services have been up and running fine.
How can we identify what is causing the node election while it was already available before. Do the attached logs suggest any specific reason for the node being re-elected as the master gateway? Are there any other logs that I can look for this information?
If this was a DB connectivity or network issue, wouldn't the logs capture it?
Please refer to the document:
You will need to set the MasterDBRefreshInterval option as shown here.
Please look for the paragraph that starts with "From PowerCenter 9.5.1 onwards, even single gateway nodes would go down with the DOM_10094 error message if node process fails to update the Master election table for 12 times."
