Work with object pool properties files

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

Determine the changes to make to your object pool 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 create, modify, or delete an object pool instance. We can also create, modify, or delete object pool custom properties.

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

Actions for object pool properties files. We can create, modify, and delete object pool instances.

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 ObjectPool instance, uncomment #DELETE=true and then run the deleteConfigProperties command.
create Property	Not applicable
delete Property	Not applicable

Actions for object pool custom properties. We can create, modify, and delete object pool custom properties.

Action	Procedure
create	Not applicable
modify	Edit properties and then run the applyConfigProperties command to modify the value of an existing custom property.
delete	Not applicable
create Property	Set properties and then run the applyConfigProperties command to create a custom property.
delete Property	Specify the properties to delete in the properties file and then run the deleteConfigProperties command to delete an existing custom property. The properties file must contain only the properties to be deleted.

Optionally, we can use interactive mode with the commands:

AdminTask.command_name('-interactive')

• Create or edit an object pool properties file.

  1. Set ObjectPool object properties as needed.

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

     #
     # Header
     #
     ResourceType=ObjectPool
     ImplementingResourceType=ObjectPoolManagerInfo
     ResourceId=Cell=!{cellName}:ObjectPoolProvider= myObjectPoolProvider:ObjectPoolManagerInfo=
     jndiName#myObjPoolJndiName:ObjectPool=poolClassName#abc,poolImplClassName#abc
     AttributeInfo=objectPools
     #DELETE=true
     
     #
     #Properties
     #
     #
     #Properties
     #
     poolClassName=abc #required
     poolImplClassName=abc #required
     #
     EnvironmentVariablesSection
     #
     #
     #Environment Variables
     cellName=myCell04

  2. Run the applyConfigProperties command to change an object pool 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 '])

• Create or edit object pool custom properties.

  1. Set ObjectPool custom properties as needed.

     Open an editor on an ObjectPool properties file. Modify the Environment Variables section to match the system and set any property value that needs to be changed. To specify a custom property, edit the AttributeInfo value and properties values; for example:

     #
     # Header
     #
     ResourceType=ObjectPool
     ImplementingResourceType=ObjectPoolManagerInfo
     ResourceId=Cell=!{cellName}:ObjectPoolProvider=myObjectPoolProvider:ObjectPoolManagerInfo=
     jndiName#myObjPoolJndiName:ObjectPool=poolClassName#abc,poolImplClassName#abc
     AttributeInfo=properties(name,value)
     #
     
     #
     #Properties
     #
     existingProp=newValue
     newProp=newValue
     
     
     #
     EnvironmentVariablesSection
     #
     #
     #Environment Variables
     cellName=myCell04

  2. Run the applyConfigProperties command.

• If you no longer need the object pool or an existing custom property, we can delete the entire object pool 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.

Results

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

Save the changes to your configuration.
