Using the script library to automate the application serving environment using wsadmin scripting

The scripting library provides a set of procedures to automate the most common application server administration functions. There are three ways to use the Jython script library.

• Run scripts from the Jython script library in interactive mode with the wsadmin tool. You can launch the wsadmin tool, and run individual scripts that are included in the script library using the following syntax:

  wsadmin>AdminServerManagement.createApplicationServer("myNode", "myServer", "default")

• Use a text editor to combine several scripts from the Jython script library, as the following sample displays:

  #
  # My Custom Jython Script - file.py
  #
  AdminServerManagement.createApplicationServer("myNode", "Server1", "default")
  AdminServerManagement.createApplicationServer("myNode", "Server2", "default")
  
  # Use one of them as the first member of a cluster
  AdminClusterManagement.createClusterWithFirstMember("myCluster", "APPLICATION_SERVER",
      "myNode", "Server1")
  
  # Add a second member to the cluster
  AdminClusterManagement.createClusterMember("myCluster", "myNode", "Server3")
  
  # Install an application
  AdminApplication.installAppWithClusterOption("DefaultApplication",
      "..\installableApps\DefaultApplication.ear", "myCluster") 
  
  # Start all servers and applications on the node
  AdminServerManagement.startAllServers("myNode")
  

  Save the custom script and run it from the command line, as the following syntax demonstrates:

  bin>wsadmin -language jython -f path/to/your/jython/file.py

• Use the Jython scripting library code as sample syntax to write custom scripts. Each script example in the script library demonstrates best practices for writing wsadmin scripts. The script library code is located in the app_server_root/scriptLibraries directory. Within this directory, the scripts are organized into subdirectories according to functionality. For example, the app_server_root/scriptLibraries/application/V70 subdirectory contains procedures that perform application management tasks that are applicable to Version 7.0 and later of the product. The subdirectory V70 in the script library paths does not mean the scripts in that subdirectory are Version 7.0 scripts.

Each script from the script library directory automatically loads when you launch the wsadmin tool. To automatically load your own Jython scripts (*.py) when the wsadmin tool starts, create a new subdirectory, and save existing automation scripts in the app_server_root/scriptLibraries directory. Each script library name must be unique and cannot be duplicated.

To automatically load Jython scripts (*.py) that are not located in the app_server_root/scriptLibraries directory when the wsadmin tool starts, set the wsadmin.script.libraries system property to the script location. For example, if your script libraries are saved in the temp directory on a Windows operating system, the following example sets the script path in the wsadmin command line tool:

bin>wsadmin -lang jython -javaoption "-Dwsadmin.script.libraries=c:/myJythonScripts" 

To load multiple directories, specify each directory in the system property separated by a semicolon (;), as the following example demonstrates:

bin>wsadmin -lang jython -javaoption "-Dwsadmin.script.libraries=c:/myJythonScripts;c:/AdminScripts;c:/configScripts"
