Error :

Feb 5, 2014 2:45:02 AM weblogic.nodemanager.server.NMServer main SEVERE: Fatal error in node manager server java.net.BindException: Address already in use at 

Reason :

The error message : java.net.BindException: Address already in use at

Shows that the Port number used by the Node Manager process is being already  used by some other process .

Solution :

1 : First thing we need to check is whether Node Manager is already running on the machine :

For unix :

ps -ef | grep nodemanager

For windows :

netstat -a0 | findstr <Node_manager port>

tasklist | findstr nodemanager

2 : If you have not observe the running process then , check which process is using the using the port assigned to node manager using lsof command or other .

By default Weblogic Node Manager runs on port : 5556 if not just check nodemanager.properties

So, to check which process is using this port use the below command .

For unix :

netstat -an | grep 5556

For Windows :

netstat -ao | findstr 5556

3 : If this port is already used by some other process try to change the Node Manager Port number from file

Middleware_Home/wlserver_10.3/common/nodemanager/nodemanager.properties file :

ListenPort = XXXX

other wise before changing , verify the process & observe the wl server home... if it is same(which you are trying)... try to kill the process & start once again with below commands

4 : Now try to start the Node manager from :

Middleware_Home/wlserver_10.3/server/bin/startNodemanager.sh or

Middleware_Home/wlserver_10.3/server/bin/startNodemanager.cmd
