Q

ORA-03121 while attaching database

A general exception has occurred during operation 'attach database' while trying to retrieve text for error ORA-03121. How do I fix this error? ORA-03121 is not listed in any of the links.

Oracle does not support attaching databases like SQL Server does. The closest thing Oracle has is the Transportable

Tablespace (TTS). To attach a tablespace with TTS, you would need the metadata dump file, the tablespace's datafiles, and the Oracle import utility.

The ORA-3121 error is "no interface driver connected - function not performed". Without knowing exactly what you were doing, and how you were doing it, I cannot guess as to why this error was received other than to say that attaching a database is not an Oracle-supported operation.
