Starting the Administration Server by Using WLST

To open WLST and start the administration server, perform the following steps:

1.	Open a terminal and navigate to the /wlserver_10.3/server/bin directory of your Oracle WebLogic Server installation.
2.	Use the setWLSEnv script to set up the environment needed for WLST. For example, on Linux: source setWLSEnv.sh
3.	Open WLST by entering the following command at the prompt: java weblogic.WLST
4.	Start the administration server by entering the following command at the WLST prompt. If necessary, replace the sample argument values with those that match your domain environment: startServer('SERVER_NAME', 'DOMAIN_NAME', 'SERVER_ADDRESS:SERVER_PORT', 'USERNAME', 'PASSWORD')

Changing a Server Property by Using WLST

To update a running server via the command line, perform the following steps:

1.	At the WLST prompt, enter the following command to connect to the running administration server. If necessary, replace the sample argument values with those that match your domain environment: connect('USERNAME', 'PASSWORD', 'SERVER_ADDRESS:SERVER_PORT') Tip: The supplied credentials should have access to the administration server. Tip: If not specified, the default protocol is 't3'.
2.	Change to edit mode by using the following command: edit()
3.	Change to the Log directory of your server by using the following command: cd('Servers/SERVER_NAME/Log/SERVER_NAME') Note: Replace SERVER_NAME with the name of your administration server.
4.	Start an edit session by using the following command: startEdit()
5.	Set the FileCount property of the administration server log file to 8 and then check whether the server property has been changed using the following commands: set('FileCount','8') ls()
6.	Save and activate the changes by using the following commands: save() activate()

Shutting Down the Administration Server by Using WLST

In this section, you use the Administration Console to modify the standard output severity threshold for the administration server.

1.
At the WLST prompt, enter the following:

shutdown()

By default, the shutdown command stops the server that you are connected to.
