How to use Applications Manager's surun command to free up ports on Unix/Linux
Applicable to Applications Manager Versions: v7.1, v8.0
If a port required by Applications Manager (AM) is in use by another process the AM processes will not start and a message will be displayed that the port is already in use.
Stop the Applications Manager processes, and run the following command from the $AW_HOME/c directory to free up the port.
surun - free <port number>
This will free up the port so that you should be able to restart all of the Applications Manager processes successfully.
