12.x
1) Identify appropriate server.xml
a) For Autosys webserver it is : cd $AUTOSUER/webserver/conf
Note: For Windows, it is %AUTOUSER%
b) For WCC it is cd $CA_WCC_INSTALL_LOCATION/tomcat/conf
Note: For Windows, it is %CA_WC_INSTALL_LOCATION%
2) Backup existing server.xml
cp -p server.xml server.xml_original
Note: for Windows, copy paste the file via File Explorer
3) Edit the original file
vi server.xml
Note: For Windows, edit via notepad
4) Search for the following line:
<Server port="8005" shutdown="">
port 8005 is the default port number that has been chosen at installation time. It might be different in each environment or installation
5) Change port "8005" to "-1"
6) Save the file
7) Restart Autosys Web Server / WCC for the change to be effective
