Update Installer abnormally ends and core dumps while applying a fix pack or interim fix
 Technote (troubleshooting)
 
Problem(Abstract)
The Update Installer can abnormally end and produce a core dump and a javacore while applying a fix pack or interim fix. This commonly occurs in environments where IBM® WebSphere® Application Server files are owned by an group ID that is not valid.
 
Cause
When creating a CD on one system for installation on another, it is possible that the username or userid does not match from one system to the other. This results in files that are owned by a username or userid that does not exist on the system, or username to userid mappings do not match.

A listing (ls -laR) of the WAS_HOME/java directory showed the following :

Notice the owner and group are numeric values. This owner cannot be found in the look-up table for username and userid. This causes the core dump and/or javacore.
 
Resolving the problem
Run the following change owner command on the directories affected to change ownership to user root, group root. The -R means to traverse through the directories recursively.

chown -R root:root *

Rerun the fixpack or fix install.
