Re: Websphere SQL prepared statement cache

We have a java app that write records to a database and this morning after websphere server had started and someone started using the application the database has one character field expanded using CHGPF. We ended and restarted that java app but when the user went to use it the server was throwing a data truncation error when it tried to write to the database. We started the same app on the test server and it worked fine. Back on the production server we found the app would work for some people but not others. We believe the server has cached the SQL statement for the connection pool based on the old field sizes and wanted to clear it to see if it fixed the problem. We did think about restarting the app server but that would take down a lot of applications.

Ending WebSphere does that but I have to ask why would you want to?

Does anyone know if there is a way to clear the SQL prepared statement cache in Websphere?
