If you are installing the Full-Text Search server component as part of ClearQuest version 8.0 or 9.0 on a 64-bit Operating System and your installed version of WebSphere is also a 64-bit edition, Full-Text Search will not work in update mode record extraction when it is run from within WebSphere's 64-bit WAS profile.
ClearQuest version 8.0 and 9.0 Full-Text Search calls into the 32-bit JNI library; WebSphere 64-bit does not support running 32-bit JNI application within a 64-bit WAS profile.
Resolving The Problem
Install the WebSphere 32-bit edition.
