Starting applications using wsadmin scripting

Use scripting and the wsadmin tool to start an application that is not running.

Before you begin

There are two ways to complete this task. This topic uses the AdminControl object to start an application. Alternatively, you can use the scripts in the AdminApplication script library to start, stop, and manage applications.

Procedure

Start the wsadmin scripting tool.

Identify the application manager MBean for the server where the application resides and assign it the appManager variable. The following example returns the name of the application manager MBean.

Using Jacl:

 set appManager [$AdminControl queryNames cell=mycell,node=mynode,type
=ApplicationManager,
process=server1,*]

Using Jython:

appManager = AdminControl.queryNames('cell=mycell,node=mynode,type
=ApplicationManager,
process=server1,*')
print appManager

Table 1. queryNames command elements . Run the queryNames command to get the name of the application manager MBean.
Command element	Description
`set`	is a Jacl command
`appManager`	is a variable name
`$`	is a Jacl operator for substituting a variable name with its value
`AdminControl`	is an object that enables the manipulation of MBeans running in a WebSphere® Application Server process
`queryNames`	is an AdminControl command
`cell=mycell,node=mynode,type=ApplicationManager` `,process=server1`	is the hierarchical containment path of the configuration object
`print`	is a Jython command

Example output:

WebSphere:cell=mycell,name=ApplicationManager,mbeanIdentifier=ApplicationManager,
type=ApplicationManager,node=mynode,process=server1

Start the application. The following example invokes the startApplication operation on the MBean, providing the application name that you want to start.

Using Jacl:

$AdminControl invoke $appManager startApplication myApplication

Using Jython:

AdminControl.invoke(appManager, 'startApplication', 'myApplication')

Table 2. invoke command elements . Run the invoke command to start the application.
Command element	Description
`$`	is a Jacl operator for substituting a variable name with its value
`AdminControl`	is an object that enables the manipulation of MBeans running in a WebSphere Application Server process
`invoke`	is an AdminControl command
`appManager`	evaluates to the ID of the server that is specified in step number 1
`startApplication`	is an attribute of the modify command
`myApplication`	is the value of the startApplication attribute
