Cause:
=====

1). The required table may be absent in the domain's Database. Follow the steps in Resolution 1 to resolve this issue.

2). This is a rare scenario in which the table was actually present but the above error was still being thrown by Administrator. It could also be caused due to an  ORACLE server "Bug 9577583 - False ORA-942 or other errors when multiple schemas have identical object names". Follow the steps in Resolution 2 to resolve this issue.

While saving Global Variable changes or deploying an application, TIBCO Administrator throws "ORA-00942: table or view does not exist.:

1). Check the Database and compare with your local setup to verify if any tables are missing. If the tables are missing then the customer can restore the DB from backup to recover the domain temporarily..

2). Use the workaround for ORACEL "Bug 9577583 - False ORA-942 or other errors when multiple schemas have identical object names".
   Workaround : Flush the SQLID of the problematic SQL statement from the SQL Area to force Oracle to reparse the statement.
   
The problematic SQL statement can be found by following the below steps.

   (i) If you enable detailed tracing on the TIBCO Administrator, perform the activity which is causing the exception.

   (ii) Check the Administrator.log file for the above error. Just before the error is thrown you will be able to locate the SQL statement that Administrator was going to fire as detailed tracing is enabled.
   
Flush the SQLID of the problematic SQL statement from the SQL Area to force Oracle to reparse the statement. You will need DBA's help at the customer end for these activities.
