If you plan to stop using Data Miner, you should drop the Repository. When you drop the Repository, all workflows and internal tables are dropped. Models created by Oracle Data Miner are dropped. Tables created by the Create Table or View node are not dropped.
Before you drop the Repository, check that no projects or workflows are open. If any connections are open, the process may fail.
During the process of dropping the repository:
The Database does not allow any new connections to be established during this process.
Any connections granted rights to the Oracle Data Miner Repository is disconnected.(This is to ensure there are no conflicts in dropping the repository.)
All workflows and internal tables are dropped. Models created by Oracle Data Miner are not dropped. Tables created by the Create Table or View node are not dropped.
Follow these steps to drop the repository:
Select Tools > Data Miner > Drop Repository
Select the connection where you want to drop the repository. You can add and edit connections, if necessary.
Log in as SYS. Click OK.
Click Start to start the drop of the repository. This process may take a several minutes. After the operation finishes, examine the log file to validate that the operation was performed.
