Description:
Upgrade fails because uorai<ver>.sql scripts are run for versions earlier than the current TIBCO iProcess Engine (iPE) version.

Symptoms:
When the option to upgrade files and database is chosen, during the Oracle upgrade section, uora<ver>.sql scripts are run for earlier versions of iPE resulting in errors being written to the tablelog. The errors relate to tables already existing, for example:

About to configure Oracle database to run TIBCO iProcess Engine
Configuring DB Users ...
Upgrading Oracle Tables (This may take some time) ...
Running upgrade script uorai111_00.sql

Cause:
The user running the installation does not have write permission to the temporary directory used for the iPE installation set.

Error while upgrading TIBCO iProcess Engine 11.3.0.

Ensure the user performing the upgrade has write permissions on the iPE installation set temporary directory.
