Running the Unicode Upgrade Utility while upgrading from TeamTrack 6.6.1 to Serena Business Mashups 2009 R1 in combination with Oracle 11g may result in the following error: Connecting to database. Oracle database client must be 9i or 10g.
When TeamTrack is required to work with multiple character sets their TT database must configure be configured for UTF-8 . With Oracle it is also a requirement for the NLS_LANG parameter to be set on the client to that of the database character set so that the data is correctly written to the database e.g. AL32UTF8.
