Shakagul If you choose the first technique, then you need to provide the method with configuration IDs for both the cluster and the node. In this example, it makes sense to use the following long form option identifiers:. Even before writing a book about WebSphere Application Server Administration Using JythonI was aware of how few examples exist that describe how you might go about creating a scriptong script. This is a 3 part tutorial series. A user could specify a blank value surrounded by double quotes:. The modified lines occur in Lines 13 through 16, where the value of the specified identifier is retrieved.

Settings based on any other code page might cause the scripts to fail. The wsadmin tool supports a full range of product administrative activities. Restriction: The wsadmin tool does not apply to Liberty. See Administering Liberty from the command line instead.
The following figure illustrates the major components involved in a wsadmin scripting solution: Figure 1. A WebSphere Application Server scripting solution. This figure illustrates the major components involved in a wsadmin scripting solution. The wsadmin tool supports two scripting languages: Jacl and Jython. Five objects are available when you use scripts: AdminControl: Use to run operational commands. AdminConfig: Use to run configurational commands to create or modify WebSphere Application Server configurational elements.
AdminApp: Use to administer applications. AdminTask: Use to run administrative commands. Help: Use to obtain general help. JMX is a technology that provides a simple and standard way to manage Java objects. Important: Some wsadmin scripts, including the AdminApp install, AdminApp update, and some AdminTask commands, require that the user ID under which the server is running must have read permission to the files that are created by the user that is running wsadmin scripting. For example, if the application server is running under user1, but you are running wsadmin scripting under user2, you might encounter exceptions involving a temporary directory.
When user2 runs wsadmin scripting to deploy an application, a temporary directory for the enterprise application archive EAR file is created. However, when the application server attempts to read and unzip the EAR file as user1, the process fails. It is not recommended that you set the umask value of the user that is running wsadmin scripting to or to work around this issue.
This approach makes all of the files that are created by the user readable by other users. To resolve this issue, consider the following approaches based on your administrative policies: Run wsadmin scripting with the same user ID as the user that runs the deployment manager or application server. A root user can switch the user ID to complete these actions.
Set the group ID of the user that is running the deployment manager or application server to be the same group ID as the user that is running wsadmin scripting. Also, set the umask value of the user that is running the wsadmin scripting to be at least a umask value so that files that are created by the wsadmin scripting can be read by members of the group. Run wsadmin scripting from a different machine. This approach forces files to be transferred and bypasses the file copy permission issue.
To perform a task using scripting, you must first perform the following steps: Procedure Choose a scripting language. The wsadmin tool only supports Jacl and Jython scripting languages. Jacl is the language specified by default. If you want to use the Jython scripting language, use the -lang option or specify it in the wsadmin. Start the wsadmin scripting client interactively, as an individual command, in a script, or in a profile. What to do next Before you perform any task using scripting, make sure that you are familiar with the following concepts: Java Management Extensions JMX WebSphere Application Server configuration model wsadmin tool Jacl syntax or Jython syntax Scripting objects Optionally, you can customize your scripting environment.
For more information, see Administrative properties for using wsadmin scripting. After you become familiar with the scripting concepts, choose a scripting language, and start the scripting client, you are ready to perform tasks using scripting. This topic highlights what is new or changed for users who are going to customize, administer, monitor, and tune production server environments using the wsadmin tool.
Getting started with wsadmin scripting
The number and type of MBeans available to the scripting client depends on the server to which the client is connected. If the client is connected to a Deployment Manager, then all the MBeans running in the Deployment Manager are visible as are all the MBeans running in the Node Agents connected to this Deployment Manager, and all the MBeans running in the application servers on those nodes. AdminConfig has commands to list, create, remove, display, and modify configuration data, as well as commands to display information about configuration data types. Most of the commands supported by AdminApp operate in two modes: the default mode is one in which AdminApp communicates with the WebSphere server to accomplish its tasks. A local mode is also possible, in which no server communication takes place. The local mode operation is invoked by bringing up the scripting client with no server connected using the command line "-conntype NONE" option or setting the "com.

Kenris In the above command, X, Y, and Z are used as placeholders. The result of the interactive call is assigned to a variable Listing 2a, Line 1 because when you are done with your interactive parameter specification, the resulting call to AdminTask. The -lang argument indicates Jython will be used Jacl is the default:. Continuing with this interactive session in Listing 2b, you are prompted for the name of the cluster in which the member is to be created. Since they are default, you can decide later whether or not your script needs to provide these values. The wsadmin tool does not apply to Liberty.
