Procedure 23.13. Edit a Thread Pool using the Management Console

  1. Login to the Management Console. Section 3.4.2, “Log in to the Management Console”.
  2. Click on the Configuration tab at the top of the screen. Expand the Container menu and select EJB 3. Select the Thread Pools tab.
  3. Select the thread pool you want to edit.
  4. Click Edit.
  5. Edit the details you want to change. Only the Thread Factory, Max Threads, Keepalive Timeout, and Keepalive Timeout Unit values can be edited.
  6. Click Save to finish.

Procedure 23.14. Edit a thread pool using the CLI

  1. Launch the CLI tool and connect to your server. Refer to Section 3.5.4, “Connect to a Managed Server Instance Using the Management CLI”.
  2. Use the write_attribute operation with the following syntax for each attribute of the thread pool to be changed.
    /subsystem=ejb3/thread-pool=THREADPOOLNAME:write-attribute(name="ATTRIBUTE", value="VALUE")
    • Replace THREADPOOLNAME with the name of the thread pool.
    • Replace ATTRIBUTE with the name of the attribute to be edited. The attributes that can be edited in this way are keepalive-time, max-threads, and thread-factory.
    • Replace VALUE with the required value of the attribute.
  3. Use the read-resource operation to confirm the changes to the thread pool.


When changing the value of the keepalive-time attribute with the CLI the required value is an object representation. It has the following syntax.
/subsystem=ejb3/thread-pool=THREADPOOLNAME:write-attribute(name="keepalive-time", value={"time" => "VALUE","unit" => "UNIT"}

Example 23.10. Set the Maxsize Value of a Thread Pool using the CLI

[standalone@localhost:9999 /] /subsystem=ejb3/thread-pool=HSThreads:write-attribute(name="max-threads", value="50")
{"outcome" => "success"}
[standalone@localhost:9999 /]

Example 23.11. Set the keepalive-time Time Value of a Thread Pool using the CLI

[standalone@localhost:9999 /] /subsystem=ejb3/thread-pool=HSThreads:write-attribute(name="keepalive-time", value={"time"=>"150"})
{"outcome" => "success"}
[standalone@localhost:9999 /]
