ConfigEngine.sh database-transfer generates a NullPointerException

Technote (troubleshooting)


Problem

When running the database-transfer task, a nullpointer exception is thrown.

ConfigEngine.sh database-transfer -DPortalAdminPwd=<password>
-DWasPassword=<password>

Reviewing the ConfigTrace.log we see the following.

Symptom

The database-transfer task fails, but some tables are able to transfer after reviewing the ConfigTrace.log.

Cause

This exception occurs when the user installs Portal as root user, then tries to run the task as a non-root user, but have not properly set up the WebSphere file structure for non-root ownership.

When attempting to do the database-transfer, the task tries to access the release domain dat file for the Derby database (which is part of the WebSphere file system), but due to the lack of permissions, the task fails.

Resolving the problem

Recommended that the user check the database dat files to ensure that the non-root user can access all the log<n>.dat files found at:

/wp_profile/PortalServer/derby/wpsdb/log.


The quick solution would be to chown everything to the non-root user for complete access.
