Work with dynamic cache properties files

We can use properties files to change dynamic cache properties under a server.

Determine the changes to make to your dynamic cache 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 a dynamic cache object and its configuration properties.

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

Actions for dynamic cache properties files. We can create, modify and delete dynamic cache 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 dynamic cache properties under a server.

  1. Specify DynamicCache properties in a properties file.

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

     serverName=myServer
     nodeName=WASNode04
     

  2. Run applyConfigProperties to change a DynamicCache 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 dynamic cache 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 dynamic cache 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
