You use script files with the Jython commands for running scripts.
Take advantage of scripting language features, such as loops, flow control constructs, conditional statements, and variable evaluations that are limited in interactive mode. All WLST commands and variables that you use in interactive and script mode can be run in embedded mode.
Example illustrates how to instantiate the WLST interpreter and use it to connect to a running server, create two servers, and assign them to clusters. The following sections describe the actions you must take to satisfy WLST security requirements:. The administration port is a special, secure port that all WebLogic Server instances in a WebLogic domain can use for administration traffic.
By default, this port is not enabled, but Oracle recommends that you enable the administration port in a production environment. The default value for the administration port is Separating administration traffic from application traffic ensures that critical administration operations starting and stopping servers, changing a server's configuration, and deploying applications do not compete with high-volume application traffic on the same network connection.
The administration port requires all communication to be secured using SSL. By default, all servers in a WebLogic domain use demonstration certificate files for SSL, but these certificates are not appropriate for a production environment.
A WebLogic domain stores its configuration data in a collection of XML documents that are saved in the domain directory. For example, these configuration documents describe the names, listen addresses, and deployed resources in the domain. When one or more servers in a WebLogic domain are running, each server instance maintains an in-memory representation of the configuration data as a collection of Managed Beans MBeans.
You must use your own security measures to make sure that only authorized users can access your domain's configuration files through the file system. Anyone who is authorized to access the domain's configuration files through the file system can use a text editor, WLST offline, or other tools to edit the configuration files.
If you use WLST to connect to a running instance of WebLogic Server, you must provide the credentials user name and password of a user who has been defined in the active WebLogic security realm. Once you are connected, a collection of security policies determine which configuration attributes you are permitted to view or modify. When you invoke the WLST connect command, you can supply user credentials by doing any of the following:.
Enter the credentials on the command line. This option is recommended only if you are using WLST in interactive mode. Enter the credentials on the command line, then use the storeUserConfig command to create a user configuration file that contains your credentials in an encrypted form and a key file that WebLogic Server uses to unencrypt the credentials.
This option is recommended if you use WLST in script mode because it prevents you from storing unencrypted user credentials in your scripts. Invoke the connect command from a directory that contains the domain's boot.
By default, when you create an Administration Server, WebLogic Server encrypts the credentials and stores them in a boot. For example, if you have not deleted the domain's boot. Some attributes of a WebLogic domain's configuration are encrypted to prevent unauthorized access to sensitive data. The attribute values are saved in the domain's configuration document as an encrypted string. In a running server instance, the values are available as an MBean attribute in the form of an encrypted byte array.
The names of encrypted attributes end with Encrypted. To write an encrypted value, pass the name of the encrypted attribute and an unencrypted string to the set command. For example:. WLST offline does not display the unencrypted value of an encrypted attribute.
If you use the ls command to display management attributes, WLST offline returns asterisks as the value of encrypted attributes. If you use the get command, WLST offline returns a byte array that represents asterisks. Pass the name of the unencrypted attribute and an unencrypted string to the set command. Pass the name of the encrypted attribute and an encrypted byte array to the set command. You can use the encrypt command to create the encrypted byte array see "encrypt" in WebLogic Scripting Tool Command Reference.
When you activate the edit, WebLogic Server writes the encrypted value to the domain's configuration file. To read the encrypted value of the attribute, pass the name of the encrypted attribute to the get command. To read the unencrypted value of the attribute, pass the name of the unencrypted attribute to the get command. The user names and passwords of WebLogic Server users, security groups, and security roles are not stored in a WebLogic domain's XML configuration documents.
Instead, a WebLogic domain uses a separate software component called an Authentication provider to store, transport, and provide access to security data. Authentication providers can use different types of systems to store security data. Listing illustrates how to instantiate an instance of the WLST interpreter and use it to connect to a running server, create two servers, and assign them to clusters.
Otherwise, at a command prompt, enter the following command:. Successfully connected to Admin Server 'myserver' that belongs to domain 'mydomain'.
If you do not, the following warning message is displayed:. Warning: An insecure protocol was used to connect to the server. To ensure on-the-wire security, the SSL port or Admin port should be used instead. For detailed information about the connect command, see connect. Follow these rules when entering WLST commands. For example:. WLST incorporates two Jython functions that support running scripts: java weblogic. WLST filePath.
To run the script examples in this guide, copy and save the commands in a text file with a. Use the text file with the commands for running scripts that are listed below.
There are sample scripts that you can use as a template when creating a script. To prevent exiting WLST, use the -i flag. WLST -i filePath. Use the following command to execute the specified script after invoking WLST. The main steps include converting WLST definitions and method declarations to a. The Jython package manager processes the JAR files in your classpath. The Jython prompt appears:.
To display information about WLST commands and variables, enter the help command. If you specify the help command without arguments, WLST summarizes the command categories. To display information about a particular command, variable, or command category, specify its name as an argument to the help command. Just e-mail: and include the URL for the page.

You can specify the username and password on the command line, or you can specify ran encrypted password that is stored locally by specifying the locations of the user configuration and key files as arguments to the connect command.
For information about creating the user configuration and key files, see help 'storeUserConfig'. See the book code download for full script Successfully connected to Admin Server 'AdminServer' that belongs to domain 'mydomain'. Search BC Oracle Sites.
