Work with eviction policy properties files

We can use properties files to set eviction policy properties, custom properties, and configuration objects.

Start wsadmin...

cd profile_root/bin
wsadmin -lang jython

...then run administrative commands...

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 eviction policy, uncomment... #DELETE=true ...then run the deleteConfigProperties command.
create Property	Not applicable
delete Property	Not applicable

Optionally, we can use interactive mode with the commands:

AdminTask.command_name('-interactive')

Create or edit an eviction policy properties file

1. Set eviction policy properties as needed.

   Open an editor on a MemoryCacheEvictionPolicy or DiskCacheEvictionPolicy properties file. Modify the Environment Variables section to match your system and set any property value that needs to be changed. To specify a custom property, edit the AttributeInfo value and properties values. An example eviction policy properties file follows:

   #
   #  MemoryCacheEvictionPolicy
   #
   ResourceType=MemoryCacheEvictionPolicy
   ImplementingResourceType=ServletCacheInstance
   ResourceId=Cell=!{cellName}:CacheProvider=myCacheProvider:ServletCacheInstance=jndiName#myServletCacheJndiName:MemoryCacheEvictionPolicy=
   AttributeInfo=memoryCacheEvictionPolicy
   #DELETE=true
   #
    #
   #Properties
   #
   lowThreshold=80 #integer,default(80)
   highThreshold=95 #integer,default(95)
    
   #
   # DiskCacheEvictionPolicy
   #
   ResourceType=DiskCacheEvictionPolicy
   ImplementingResourceType=ServletCacheInstance
   ResourceId=Cell=!{cellName}:CacheProvider=myCacheProvider:ServletCacheInstance=jndiName#myServletCacheJndiName:DiskCacheEvictionPolicy=
   AttributeInfo=diskCacheEvictionPolicy
   #DELETE=true
   #
    #
   #Properties
   #
   algorithm=NONE #ENUM(RANDOM|SIZE|NONE),default(NONE)
   lowThreshold=90 #integer,default(90)
   highThreshold=95 #integer,default(95)
    #
   EnvironmentVariablesSection
   #
   #
   #Environment Variables
   cellName=myCell04

2. Run the applyConfigProperties command to create or change an eviction policy 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 the entire eviction policy object or the custom property

• To delete the entire object, specify DELETE=true in the header section of the properties file and run the deleteConfigProperties command; for example:
  AdminTask.deleteConfigProperties('[-propertiesFileName myObjectType.props -reportFileName report.txt]')

• To delete a custom property, specify only the property to be deleted in the properties file and then run the deleteConfigProperties command.
