Work with object cache J2EE resource properties files

We can use properties files to create, modify, or delete object cache J2EE resource custom properties.

Determine the changes to make to your object cache J2EE resource configuration.

Start the wsadmin scripting tool.

To start wsadmin using the Jython language, run the wsadmin -lang Jython command from the bin directory of the server profile.

Use a properties file, you can create, modify, or delete object cache J2EE resource custom properties.

Run administrative commands using wsadmin to change a properties file for an object cache J2EE resource, validate the properties, and apply them to the configuration.

Actions for object cache J2EE resource properties. We can create, modify, and delete object cache J2EE resource custom properties.

Action	Procedure
create	Not applicable
modify	Edit properties and then run the applyConfigProperties command to modify the value of an existing custom property.
delete	Not applicable
create Property	Set properties and then run the applyConfigProperties command to create a custom property.
delete Property	Specify the properties to delete in the properties file and then run deleteConfigProperties to delete an existing custom property. The properties file must contain only the properties to be deleted.

Optionally, you can use interactive mode with the commands:

AdminTask.command_name('-interactive')

Procedure

• Create object cache J2EE resource properties.

  1. Specify ObjectCacheInstance J2EEResourcePropertySet custom properties in a properties file.

     Open an editor and specify object cache J2EE resource properties in a properties file. We can copy the following example properties into an editor and modify the properties as needed for your situation.

     To specify a custom property, edit the AttributeInfo value and properties values.

     #
     # Header
     #
     ResourceType=J2EEResourcePropertySet
     ImplementingResourceType=ObjectCacheInstance
     ResourceId=Cell=!{cellName}:Node=!{nodeName}:Server=!{serverName}:CacheProvider=myCacheProvider:
     ObjectCacheInstance=jndiName#myObjectCacheJndiName:J2EEResourcePropertySet=
     AttributeInfo=resourceProperties(name,value)
     
     #
     #Properties
     #
     existingProp=newValue
     newProp=newValue
     
     
     #
     EnvironmentVariablesSection
     #
     #
     #Environment Variables
     cellName=myCell04
     serverName=odr
     nodeName=myNode03
     

  2. Run applyConfigProperties to create or change an object cache J2EE resource 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 '])
     

• Modify existing object cache J2EE resource properties.
  1. Obtain a properties file for the object cache J2EE resource to change.

     We can extract a properties file for an ObjectCacheInstance J2EEResourcePropertySet using the extractConfigProperties command.

  2. Open the properties file in an editor and change the custom properties as needed.

     Ensure that the environment variables in the properties file match the system.

  3. Run applyConfigProperties.

• If you no longer need an object cache J2EE resource custom property, you can delete the custom property.

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

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

Results

We can use the properties file to configure and manage the object cache J2EE resource 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
