Troubleshooting Change In Behavior Following Fix Pack Install
 Technote (troubleshooting)
 
Problem(Abstract)
Temporary/test fixes applied to the <wasroot>/classes directory can change product behavior following a Fix Pack install
 
Symptom
Change In Behavior Following Fix Pack Install
 
Cause
Temporary/test fixes applied to the <wasroot>/classes directory can change product behavior following a Fix Pack install if allowed to remain in the <wasroot>classes directory.
 
Diagnosing the problem
On occasion, a temporary or test fix may be provided by IBM® support. If install directions include copying the provided fix to the <wasroot>classes folder then caution must be exercised while applying a Fix Pack install.
The Update Installer tool does not consider the classes folder and will not remove any fixes in that folder. You should receive a warning that there are entries in the classes folder that should be removed. This warning does not stop the update from being applied.

Code which remains in the <wasroot>/classes folder following Fix Pack install takes precedence over other WebSphere® Application Server binaries and may cause a regression for a particular component.
 
Resolving the problem
For a change In behavior following Fix Pack Install
1) Verify that the updateinstaller completed successfully by checking the update installer logs in the <wasroot>/logs/update folder

2) Verify that there are no files present in the <wasroot>classes folder. If temporary or test fixes are in the <wasroot>classes directory, remove the files from the <wasroot>classes directory and restart WebSphere Application Server to see if this is the cause of the problem.

3) If a change In behavior persists, check the IBM support site for known issues or contact IBM WebSphere Application Server Support
