Tuning the SIBWS

You can use the administrative console or a Jacl script to tune performance settings for the service integration bus Web services enablement (SIBWS).

Why and when to perform this task

The SIBWS dynamically selects an optimized route through the code where possible. If you migrate Web services from the WebSphere Application Server Version 5 Web services gateway, and you do not use mediations to support previous Gateway filter applications, then your messages avoid being routed through the internal infrastructure that enables additional SIBWS functionality. This fast-path route through the bus is used if the following criteria are met:

If your Web services use the fast-path route, you need not tune mediations or the service integration bus. However it is good practise to do so, because a typical environment will have at least one non-fast-path (for example, mediated) service.

To improve the performance of the SIBWS, you can tune the following parameters:

If you have mediations that act on SOAP headers, you can improve performance by inserting the associated header schemas (.xsd files) into the SDO repository.

To tune the SIBWS, complete one of the following two steps: If you have mediations that act on SOAP headers, also complete the following step:
