You can use properties files to create, modify, or delete
object cache properties and custom properties.
Before you begin
Determine the changes that you want to make to your object
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.
About this task
Using a properties file, you can create, modify, or delete
an object cache instance. You can also create, modify, or delete object
cache custom properties.
Run administrative commands using wsadmin
to create or change a properties file for an object cache, validate
the properties, and apply them to your configuration.
Table 1. Actions for object cache
properties files . You can create, modify, and delete
object cache properties.
Action |
Procedure |
create |
Set required properties and then run the applyConfigProperties
command. |
modify |
Edit properties and then run the applyConfigProperties
command to modify the value of a custom property. |
delete |
Run the deleteConfigProperties command to delete
a property. If the deleted property has a default value, the property
is set to the default value. To delete the entire ObjectCacheInstance
object, uncomment #DELETE=true and then run the deleteConfigProperties
command. |

Optionally, you can use interactive mode with the commands:
AdminTask.command_name('-interactive')
Procedure
- Create or edit an ObjectCacheInstance properties file.
- Set ObjectCacheInstance properties as needed.
Open an editor on an ObjectCacheInstance properties file.
Modify the Environment Variables section to match your system and
set any property value that needs to be changed. An example ObjectCacheInstance
properties file follows:
#
# Header
#
ResourceType=ObjectCacheInstance
ImplementingResourceType=ObjectCacheInstance
ResourceId=Cell=!{cellName}:Node=!{nodeName}:Server=!{serverName}:CacheProvider=myCacheProvider:
ObjectCacheInstance=jndiName#myObjectCacheJndiName
#DELETE=true
#
#
#Properties

diskCacheEntrySizeInMB=0 #integer,default(0)
defaultPriority=1 #integer,required,default(1)
useListenerContext=false #boolean,default(false)
pushFrequency=1 #integer,default(1)
memoryCacheSizeInMB=0 #integer,default(0)

diskCacheSizeInGB=0 #integer,default(0)
enableCacheReplication=false #boolean,default(false)
cacheSize=2000 #integer,required,default(2000)

- Run the applyConfigProperties command to change an object
cache 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 '])
- If you no longer need the object cache or an existing custom
property, you can delete the entire object cache instance or the custom
property.
Results
You can use the properties file to configure and manage
the object cache instance and its properties.
What to do next
Save the changes to your configuration.
