Setting thread pool values

Set the thread pool values for an IBM® Sametime® Gateway server and the SIP container to improve performance between the SIP container and the Sametime Gateway application server layer. By using a thread pool, server components can reuse existing threads, which helps improve performance by reducing the overhead of creating new threads at run time.

Procedure

  1. From Integrated Solutions Console, click Servers > Server Types > WebSphere application servers > RTCGWServer, and then in the "Additional Properties" section, click Thread Pools.
  2. Click New, and then type a name of your choice, such as STGWPool, in the Name field.
  3. Type 30 in the Minimum Size field.
  4. Type 30 in the Maximum Size field.
  5. Keep the default value of 5000 for thread inactivity.
  6. Click OK, and click Save to save changes to the master configuration.
  7. Click Servers > Server Types > WebSphere application servers > RTCGWServer, and in the "Container Settings" section, select SIP Container Settings > SIP Container.
  8. From the list of Thread pool, select the thread pool that you just created.
  9. Set Maximum dispatch queue size to 5000.
  10. Keep the default values of 120000 for Maximum application sessions, and 5000 for Maximum messages per averaging period.
  11. Click OK, and click Save to save changes to the master configuration.
  12. If Sametime Gateway is clustered, repeat the preceding steps for each node of the cluster.
