Procedure 16.14. Edit 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 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. 
    /subsystem=ejb3/thread-pool=THREADPOOLNAME:read-resource

Important

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 16.10. 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 16.11. 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 /]
