Configuring the mediation thread pool

Use this task to configure the mediation thread pool.

Before you begin

The wsadmin tool must be running. For more information, see ../../com.ibm.websphere.express.doc/info/exp/ae/txml_launchscript.html.

Why and when to perform this task

You need to configure the mediation thread pool if you want to change the number of threads used when running mediations concurrently. The maximum size of the thread pool determines the maximum number of messages that can be mediated concurrently for a messaging engine.

The mediations thread pool, attribute name mediationsThreadPool, is an attribute of the messaging engine. By default, mediationsThreadPool does not exist, and a default thread pool is created and used at runtime. In this task, use the wsadmin tool to create a threadpool object, and then modify its properties using Jacl, as shown in the examples below:

Steps for this task

  1. Use this example to create a mediationThreadPool object:
    $AdminConfig create ThreadPool $messagingEngine {{name stitch.server1-bus2-mediationThreadPool}} mediationThreadPool
    Tip: In this case, the thread pool name is based on the name of the messaging engine. Although it is not required to do this, it makes it easier to find the thread pool name when using Performance Monitoring Infrastructure (PMI).
  2. Use this example to modify a mediationThreadPool object:
    $AdminConfig modify [$AdminConfig showAttribute $messagingEngine mediationThreadPool] {{maximumSize 10}}
    {{maximumSize}} can contain any of the mediationsThreadPool properties. To add additional parameters, insert {attribute name attribute value} within the outer curly brackets ({}).
    Tip: There is a space between attribute name and attribute value.
