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 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. Using a properties file, we 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 your 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 the applyConfigProperties command. delete Not available create Property Set properties and then run the applyConfigProperties command. delete Property To delete one or more properties, run deleteConfigProperties with only those properties to delete in the properties file. Optionally, we can use interactive mode with the commands:
AdminTask.command_name('-interactive')
- Create or edit dynamic cache properties under a server.
- 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 the situation.

- Run the applyConfigProperties command to change a DynamicCache configuration.
Running the applyConfigProperties command 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 manage dynamic cache properties.
Save the changes to your configuration.
