Procedure 19.14. Edit a thread pool using the CLI
- 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”.
- 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
, andthread-factory
. - Replace VALUE with the required value of the attribute.
- 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 19.10. 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 19.11. 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 /]
