The statement cache is configured on the Data Source properties in WAS. You probably want to check with your WAS admin what's the minimal way of flushing it without bouncing WAS itself ( bouncing the app alone wont help)

During a performance tuning session we found a query using an index that did not have a vital column. We added the missing column to the end of the index on a test database and using a db2 query analyzer we saw a big performance gain. We moved the index to our production servers and see similar gains using db2 tools, however we do not see the benefit in the WebSphere application. How/Where are are prepared statements cached and how can I clear them to get a plan that takes advantage of the new index.
