Work with EJB container properties files

We can use properties files to change EJB container properties and associated stateManagement, cacheSettings and timerSettings attributes under a server.

Determine the changes to make to your EJB container configuration or its configuration objects.

Start wsadmin.sh.

To start wsadmin using the Jython language, run...

WP_PROFILE/bin/wsadmin -lang jython

Use a properties file, you can modify an EJB container object and its configuration properties.

Run administrative commands using wsadmin to change a properties file for an EJB container, validate the properties, and apply them to the configuration.

Actions for EJB container properties files. We can create, modify and delete EJB container properties.

Action	Procedure
create	Not available
modify	Edit properties and then run applyConfigProperties.
delete	Not available
create Property	Set properties and then run applyConfigProperties.
delete Property	To delete one or more properties, run deleteConfigProperties with only those properties to delete in the properties file.

Optionally, you can use interactive mode with the commands:

AdminTask.command_name('-interactive')

Procedure

• Create or edit EJB container properties under a server.

  1. Specify EJBContainer properties in a properties file.

     Open an editor on a properties file. Example properties for an EJBContainer under a server follow. A property under EJBContainer has a name of myName and a value of myVal. We can copy the example properties into an editor and modify the stateManagement, cacheSettings and timerSettings attributes under the server as needed for your situation.

  2. Run applyConfigProperties to change an EJBContainer configuration.

     Run applyConfigProperties applies the properties file to the configuration. In this Jython example, the optional -reportFileName parameter produces a report named report.txt:

     AdminTask.applyConfigProperties(['-propertiesFileName myObjectType.props -reportFileName report.txt'])
     

• Delete EJB container properties.

  To delete one or more properties, specify only those properties to delete in the properties file and run deleteConfigProperties; for example:

  AdminTask.deleteConfigProperties('[-propertiesFileName myObjectType.props -reportFileName report.txt]')
  

Results

We can use the properties file to configure and manage the EJB container properties.

What to do next

Save the changes to the configuration.
Extract properties files using wsadmin.sh
Create server, cluster, application, or authorization group objects using properties files and wsadmin scripting
Delete server, cluster, application, or authorization group objects using properties files
