CLM 4.0.5 performance reports

To coincide with the CLM 4.0.5 release, the performance team has produced six — that’s six! — reports.

Collaborative Lifecycle Management performance report: RTC 4.0.5 release compares the performance of an unclustered Rational Team Concert version 4.0.5 deployment to the previous 4.0.4 release. With the workload as described in the report, we found no performance regressions between current release and prior release.

RTC for z/OS recently introduced a Java API to access JFS (Jazz Foundation Services) instead of using the HTTP APIs which provides the potential for significant performance improvements. The Rational Team Concert for z/OS performance impact of Java JFS API adoption in 4.0.5 report compares the performance before and after RTC for z/OS adopted the Java JFS API in part of the resource operations and queries. Comparison is made between the 4.0.5 RC1 development version and the previous 4.0.4 release.

Collaborative Lifecycle Management performance report: RRC 4.0.5 release compares the performance of an unclustered Rational Requirements Composer version 4.0.5 deployment to the previous 4.0.4 release.

Similarly, Collaborative Lifecycle Management performance report: Rational Quality Manager 4.0.5 release compares the performance of an unclustered Rational Quality Manager version 4.0.5 deployment to the previous 4.0.4 release.

There were design changes to ETL functionality for RM which are highlighted in Collaborative Lifecycle Management performance report: Export Transform Load (ETL) 4.0.5 release. This report presents the results of “Extract, Transform, and Load” (ETL) performance testing for CLM. The ETL type includes Java ETL and DM ETL. Data load includes full load and delta load. The article focusses on ETL performance comparison between the 4.0.5 release and the 4.0.4 release.

Finally, the CLM Reliability report: CLM 4.0.5 release presents a sample of the results from a CLM 405 Reliability test. Reliability testing is about exercising the CLM applications so that failures are discovered and removed before the system is deployed. There are many different combinations of pathways through the complex CLM application, this test scenario exercises the most likely use cases. The use cases are put under constant load for a seven day period to validate that the CLM application provides the expected level of service, without any downtime or degradation in overall system performance.
