Work with object pool provider properties files

We can use properties files to create, modify, or delete object pool provider properties and custom properties.

Determine the changes to make to the object pool provider configuration or its configuration objects.

From the server profile bin directory, run wsadmin -lang jython

Using a properties file, we can create, modify, or delete an object pool provider instance. We can also create, modify, or delete object pool provider custom properties.

Run administrative commands using wsadmin to create or change a properties file for an object pool provider, validate the properties, and apply them to your configuration.

for object pool provider properties files. We can create,

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 ObjectPoolProvider instance, uncomment #DELETE=true and 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 object pool provider properties file.

  1. Set ObjectPoolProvider properties as needed.

     Open an editor on an ObjectPoolProvider properties file. Modify the Environment Variables section to match the system and set any property value that needs to be changed. An example ObjectPoolProvider properties file follows:

     #
     # Header
     #
     ResourceType=ObjectPoolProvider
     ImplementingResourceType=ObjectPoolProvider
     ResourceId=Cell=!{cellName}:ObjectPoolProvider=myObjectPoolProvider
     #DELETE=true
     #
      #
     #Properties
     #
     classpath={}
     name=myObjectPoolProvider # required
     isolatedClassLoader=false #boolean,default(false)
     nativepath={}
     description=Default Object Pool Provider providerType=null #readonly
      #
     EnvironmentVariablesSection
     #
     #
     #Environment Variables
     cellName=myCell04

  2. Run the applyConfigProperties command to change an object pool provider 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 we no longer need the object pool provider or an existing custom property, we can delete the entire object pool provider 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.

Results

We can use the properties file to configure and manage the object pool provider instance and its properties.

What to do next

Save the changes to the configuration.
