Importance of Administration Port on WebLogic
This feature is very important for WebLogic domain management but WebLogic admins usually don’t take advantage of “WebLogic Administration Port” property.
I am highly recommending enabling “Administration Port” for WebLogic domains which have high transaction traffic.
Why WebLogic Administration Port?
By enabling Administration Port, you can separate administration traffic from application traffic in your domain. That’s fair enough to switch your WebLogic management to administration port.
Oracle Documentation: In production environments, separating the two forms of traffic ensures that critical administration operations (starting and stopping servers, changing a server’s configuration, and deploying applications) do not compete with high-volume application traffic on the same network connection.
How to do it?
1. Firstly, shutdown all managed servers. This means for the production systems, you have to make a planned system work. If you don’t want to make and downtime do the restart job one by one.
2. Click “Domain name” on the Domain Structure menu. On “$Domain_Name > Configuration > General” tab, then make “Enabled Administration Port” checked as below (No: 1). Change default port value to another, I’ve set it to 9902 (No:2) Read the complete article here.
