Work with thread pool properties files

We can use properties files to create or change Message Listener Service thread pool properties under a server.

Determine the changes to make to your thread pool configuration or its configuration objects.

Start wsadmin.sh.

cd $WP_PROFILE/bin
./wsadmin.sh -lang

Use a properties file, you can create, modify, or delete a thread pool object and its configuration properties.

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

Actions for Message Listener Service thread pool properties files

Action	Procedure
create	Set properties and then run applyConfigProperties.
modify	Edit properties and then run applyConfigProperties.
delete	Uncomment #DELETE=true and run deleteConfigProperties.
create Property	Not applicable
delete Property	Not applicable

Optionally, you can use interactive mode with the commands:

AdminTask.command_name('-interactive')

Create a thread pool and its properties

1. Create ThreadPool properties in a properties file.

   Open an editor and specify thread pool properties. We can copy the following example properties into an editor and modify the properties as needed for your situation. The example defines a thread pool under the MessageListenerService under a server.

   #
   # SubSection 1.0.1 # MessageListenerService ThreadPool
   #
   ResourceType=ThreadPool
   ImplementingResourceType=GenericType
   ResourceId=Cell=!{cellName}:Node=!{nodeName}:Server=!{serverName}:ApplicationServer=:EJBContainer=:MessageListenerService=:ThreadPool=
   AttributeInfo=threadPool
   #
   
   #
   #Properties
   #
   maximumSize=50 #integer,required,default(5)
   name=Message.Listener.Pool
   minimumSize=10 #integer,required,default(1)
   inactivityTimeout=3500 #integer,required,default(5000)
   description=null
   isGrowable=false #boolean,default(false)
   
   EnvironmentVariablesSection
   
   #Environment Variables
   cellName=WASCell06
   serverName=myServer
   nodeName=WASNode04
   

2. Run applyConfigProperties to create a thread pool configuration.

   Run applyConfigProperties 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'])

Modify an existing thread pool

1. Obtain a properties file for the thread pool that you want to change.

   We can extract a properties file for a ThreadPool object using the extractConfigProperties command.

2. Open the properties file in an editor and change the properties as needed.

   Ensure that the environment variables in the properties file match the system.

3. Run applyConfigProperties to change a thread pool configuration.

If you no longer need a thread pool

If you no longer need a thread pool, you can delete the entire thread pool object.

Specify DELETE=true in the header section of the properties file and run deleteConfigProperties; for example:

AdminTask.deleteConfigProperties('[-propertiesFileName myObjectType.props -reportFileName report.txt]')
