You can enable or disable a background application using scripting
and the wsadmin tool.
About this task
Background applications specify whether the application must initialize
fully before the server starts. The default setting is false and
this indicates that server startup will not complete until the application
starts. If you set the value to true, the application starts on a
background thread and server startup continues without waiting for the application
to start. The application may not ready for use when the application server
starts.
Procedure
- Locate the application deployment object for the application. For
example:
Using Jacl:
set applicationDeployment [$AdminConfig getid /Deployment:adminconsole/ApplicationDeployment:/]
Using Jython:
applicationDeployment = AdminConfig.getid('/Deployment:adminconsole/ApplicationDeployment:/')
where:
set |
is a Jacl command |
applicationDeployment |
is a variable name |
$ |
is a Jacl operator for substituting a variable name
with its value |
AdminConfig |
is an object that represents the WebSphere Application
Server configuration |
getid |
is an AdminConfig command |
Deployment |
is a type |
ApplicationDeployment |
is a type |
adminconsole |
is the name of the application |
- Enable the background application. For example:
Using Jacl:
$AdminConfig modify $applicationDeployment "{backgroundApplication true}"
Using Jython:
AdminConfig.modify(applicationDeployment, ['backgroundApplication', 'true'])
where:
$ |
is a Jacl operator for substituting a variable name
with its value |
AdminConfig |
is an object that represents the WebSphere Application
Server configuration |
modify |
is an AdminConfig command |
applicationDeployment |
is a variable name that was set in step
1 |
backgroundApplication |
is an attribute |
true |
is the value of the backgroundApplication attribute |
