Automating application configurations using wsadmin scripting
The scripting library provides Jython script procedures to assist in automating your environment. Use the application management scripts to install, uninstall, export, start, stop, and manage applications in your environment.
About this task
- 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:
Save the custom script and run it from the command line, as the following syntax demonstrates:# # 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")
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.
You can use the AdminApplication.py scripts to perform multiple combinations of administration functions. Use the following steps to use the scripting library to install an application on a cluster and start the application:
Procedure
Results
The wsadmin script libraries return the same output as
the associated wsadmin commands. For example, the AdminServerManagement.listServers()
script returns a list of available servers. The AdminClusterManagement.checkIfClusterExists()
script returns a value of true
if the cluster exists,
or false
if the cluster does not exist. If the command
does not return the expected output, the script libraries return a
1 value when the script successfully runs. If the script fails, the
script libraries return a -1 value and an error message with the exception.
true
as the last argument for the script
procedure, as the following example displays: wsadmin>AdminApplication.startApplicationOnCluster("myApplication","myCluster","true")
What to do next
Create custom scripts to automate your environment by combining script procedures from the scripting library. Save custom scripts to a new subdirectory of the app_server_root/scriptLibraries directory.
