Q. How do I provide user credentials for starting a server?

A. When you create a domain, the Configuration Wizard prompts you to provide the username and password for an initial administrative user. If you create the domain in development mode, the wizard saves the username and encrypted password in a boot identity file. A WebLogic Server instance can refer to a boot identity file during its startup process. If a server instance does not find such a file, it prompts you to enter credentials.

If you create a domain in production mode, or if you want to change user credentials in an existing boot identity file, you can create a new boot identity file. WebLogic Server does not support copying a boot identity file from one server root directory to another. For information on creating and using boot identity files, see Boot Identity Files in Administration Console Online Help.

Q. Can I start a Managed Server if the Administration Server is unavailable?

A. By default, if a Managed Server is unable to connect to the specified Administration Server during startup, it can retrieve its configuration by reading a configuration file and other files directly. You cannot change the server's configuration until the Administration Server is available. A Managed Server that starts in this way is running in Managed Server Independence mode. For more information, see Starting a Managed Server When the Administration Server Is Not Accessible in Configuring and Managing WebLogic Server.

Q. What is the easiest way to set the classpath?

WebLogic Server installs the following script that you can use to set the classpath that a server requires:
`WL_HOME``\server\bin\setWLSEnv.cmd` (on Windows)
`WL_HOME``/server/bin/setWLSEnv.sh` (on UNIX)

where `WL_HOME` is the directory in which you installed WebLogic Server. For more information, see "Setting the Classpath" in the WebLogic Server Command Reference.

Q. How do I edit the `config.xml` file?

A. The persistent configuration for a domain of WebLogic Servers and clusters is stored in an XML configuration file (`config.xml`). You can modify this file in the following ways:

- Use the Administration Console. See "Using the Administration Console" in the Administration Console Online Help.
- If you want to create scripts that automate domain management, use the `weblogic.Admin` utility. See "weblogic.Admin Command-Line Reference" in the `.`
- If you want to create Java-based management applications, use the Java Management Extensions (JMX) Application Programming Interface (API). See the Programming WebLogic Management Services with JMX guide.
- If you want to edit the `config.xml` file directly (not recommended), see the BEA WebLogic Server Configuration Reference.

Q. Is there a quick way to create and start a remote Managed Server?

A. The recommended approach is to use the Domain Configuration Wizard, as described in "Setting Up and Starting Managed Servers on a Remote Machine" in Creating WebLogic Configurations Using the Configuration Wizard at `http://e-docs.bea.com/platform/docs81/confgwiz/multi.html`.

For a streamlined approach, follow the instructions at "Starting Managed Servers From a WebLogic Server Script" in the Administration Console Online Help.

Q. The Tree View pane of the WebLogic Console is not visible in my browser. How do I enable it?

A. Enable the Sun Java Plug-In from the control panel.
