DynamicCache command group

We can use Jython to manage the dynamic cache service. Use the commands in the DynamicCache command group to create object and service cache instances with wsadmin.sh.

Use the following commands to manage your dynamic cache configuration:

• createObjectCacheInstance

• createServletCacheInstance

createObjectCacheInstance

The createObjectCacheInstance command creates an object cache instance in the configuration. An object cache is a location where the dynamic cache stores, distributes, and shares data.

Target object

Specify the instance of the cache provider that the system stores the object cache instance objects under.

Required parameters

-name

Name of the object cache instance to create. (String, required)

-jndiName

JNDI name for the object cache instance to create. (String, required)

Return value

The command does not return output.

Batch mode example usage

• Jython string:

  AdminTask.createObjectCacheInstance('CacheProvider(cells/myCell/nodes/myNode/servers/myServer|resources-pme502.xml#
  #CacheProvider_1055745612404)','[-name objectName -jndiName myJNDI]')
  

• Use Jython list:

  AdminTask.createObjectCacheInstance('CacheProvider(cells/myCell/nodes/myNode/servers/myServer|resources-pme502.xml#
  #CacheProvider_1055745612404)',['-name', 'objectName', '-jndiName', 'myJNDI'])

### Jython

AdminTask.createObjectCacheInstance('-interactive')

createServletCacheInstance

The createServletCacheInstance command creates a servlet cache instance in the configuration. A servlet cache instance specifies the location where the dynamic cache stores, distributes, and shares data.

Target object

Specify the instance of the cache provider that the system stores the object cache instance objects under.

Required parameters

-name

Name of the servlet cache instance to create. (String, required)

-jndiName

JNDI name for the servlet cache instance to create. (String, required)

Return value

The command does not return output.

Batch mode example usage

• Jython string:

  AdminTask.createServletCacheInstance('CacheProvider(cells/myCell/nodes/myNode/servers/myServer|resources-pme502.xml
  l#CacheProvider_1055745612404)','[-name servletName -jndiName myJNDI]')
  

• Use Jython list:

  AdminTask.createServletCacheInstance('CacheProvider(cells/myCell/nodes/myNode/servers/myServer|resources-pme502.xml
  l#CacheProvider_1055745612404)',['-name', 'servletName', '-jndiName', 'myJNDI'])
  

Interactive example...

### Jython

AdminTask.createServletCacheInstance('-interactive')

Use the DistributedMap and DistributedObjectCache interfaces for the dynamic cache
Use object cache instances
