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 wsadmin.sh.
To start wsadmin using the Jython language, run the wsadmin -lang Jython command from the bin directory of the server profile.
Use a properties file, you 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 the 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 deleteConfigProperties 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 deleteConfigProperties to delete an existing custom property. The properties file must contain only the properties to be deleted. Optionally, you can use interactive mode with the commands:
AdminTask.command_name('-interactive')
Procedure
- Create or edit an object pool properties file.
- 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- Run applyConfigProperties to change an object pool configuration.
Run 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.
- 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- Run applyConfigProperties.
- If you no longer need the object pool or an existing custom property, you 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 deleteConfigProperties.
Results
We can use the properties file to configure and manage the object pool instance and its properties.
What to do next
Save the changes to the configuration.
Extract properties files using wsadmin.sh
