  5. Click on the Save button to save the new thread pool or click the Cancel link to abort the procedure.
    • If you click the Save button, the dialog will close and the new thread pool will appear in the list.
    • If you click Cancel, the dialog will close and no new thread pool will be created.

Procedure 16.10. Create a Thread Pool using the CLI

  1. Launch the CLI tool and connect to your server. Refer to Section 3.3.4, “Connect to a Managed Server Instance Using the Management CLI”.
  2. Use the add operation with the following syntax. 
    /subsystem=ejb3/thread-pool=THREADPOOLNAME:add(max-threads=MAXSIZE, keepalive-time={"time"=>"TIME", "unit"=>UNIT"})
    • Replace THREADPOOLNAME with the required name for the thread pool.
    • Replace MAXSIZE with the maximum size of the thread pool.
    • Replace UNIT with the required time unit to be used for the required keep-alive time. Allowed values are: NANOSECONDS, MICROSECONDS, MILLISECONDS, SECONDS, MINUTES, HOURS, and DAYS.
    • Replace TIME with the integer value of the required keep-alive time. This value is a number of UNITs.
  3. Use the read-resource operation to confirm the creation of the bean pool. 
    /subsystem=ejb3/strict-max-bean-instance-pool=THREADPOOLNAME:read-resource

Example 16.7. Create a Thread Pool using the CLI

[standalone@localhost:9999 /] /subsystem=ejb3/thread-pool=testmepool:add(max-threads=50, keepalive-time={"time"=>"150", "unit"=>"SECONDS"})
{"outcome" => "success"}
[standalone@localhost:9999 /]

Example 16.8. XML Configuration Sample

<subsystem xmlns="urn:jboss:domain:ejb3:1.2">

   <thread-pools>
      <thread-pool name="default" max-threads="20" keepalive-time="150"/>
   </thread-pools>

</subsystem>
