Increase the query cache size to prevent Query Expired issue

Technote (troubleshooting)


This technote explains the Query Expired error message that can occur when using IBM Rational Team Concert, and describes how to resolve it.


The Eclipse client or the Web client sometimes shows a Query Expired error message when running a query:

Only part of the query runs.

The query returns some results but does not report the total number of work items.

This problem applies to both 1.X and 2.0, and both to the Eclipse UI and the Web UI.
