Tune Web services based on Web Services for J2EE
Overview
Performance considerations are the same for Web services applications that are developed and implemented based on the Web Services for Java 2 platform, Enterprise Edition (J2EE) and regular J2EE applications. See Tuning performance for more information about analyzing and tuning J2EE applications.
Overview
You can use the Performance Monitoring Infrastructure (PMI) to measure the time required to process Web services requests. To monitor Web services application performance:- Enable PMI services
in appserver through the administrative console.Select
the Web Service module, named webServicesModule, in step 7.
- Monitor performance with Tivoli Performance ViewerIn the left-hand pane of the performance view, expand the host and server and select Web Services. Run the Web services client application.
Results
Measurements are available for the following items:
- Number of Web services loaded by the appserver
- Number of requests received
- Number of requests dispatched to an implementation bean
- Number of requests dispatched with successful replies
- Average time in milliseconds between receiving the request and returning
the reply
- Average time in milliseconds between receiving the request and dispatching
it to the bean
- Average time in milliseconds between dispatch and receipt of reply from
the bean
- Average time in milliseconds between receipt of reply from bean to return
of result to client
- Average size of request and reply
- Average size of request
- Average size of reply
