Possible causes for this message.
Resolution:• if you just had created the database and want to create a new instance: access the application and choose the appropriate system type you want to be created. The application then creates the database structure and fills the tables with records• if you already had a running instance and get this error, contact a DBA to check the application user's permissions to access the existing tables• if you had an existing instance but there are no more tables in the DB you need to have a database backup being recovered by your DBA
Thanks for the tip Debbie!
