Determining the Status and Version of the Repository
The version of the repository must be compatible with the version of the Oracle Data Miner client. If the client and server versions are not compatible, then the client cannot connect to the server.
Backing Up and Restoring the Repository
Before upgrading the Oracle Data Miner repository or performing a database upgrade, you should perform a full backup of Oracle Data Miner, including ODMRSYS and the Oracle Data Miner user schemas.
