Performance troubleshooting

This page is the starting point for information and techniques to help diagnose performance issues when using the IBM Rational Collaborative Lifecycle Management (CLM) family of products (Rational Team Concert, Rational Requirements Composer, and Rational Quality Manager).

How to use this performance troubleshooting guide

The situations listed below are divided into two groups: situations likely to be encountered by administrators, and situations likely to be encountered by users of the CLM products.

If you are new to troubleshooting, see How to start a troubleshooting assessment.

Administrator situations

• Why is the database consuming so many resources?
• Why do I get out-of-memory (OOM) errors in the log files?
• Why do my ETLs take so long to run?
• Why is my CPU spiking?
• How do I determine if my server has enough memory?
• How do I determine if the database has a problem?
• How do I determine if my network has a problem?
• Troubleshooting problems in virtualized environments
• Why do some pages take two minutes to load?

User situations

• Why is browser performance slow?
• Why does my Rational Team Concert plan take so long to load?
• Why is the Rational Team Concert client slow?
