Portal Fix Pack 6.0.1.7 error on linux

The error message bellow appears when the owner of the file wpsconfig.sh is different from the owner of the Fix Pack 6.0.1.7 files

Error ( 2 ): IOException creating RunTime(): /opt/ibm/WebSphere/PortalServer/config/WPSconfig.sh: cannot execute
Error 112 -- Return code (888) differs from the expected code (0).

To solve the problem change the owner of the WPSconfig.sh to match the owner of the Fix Pack files.
