7.5.2 Uninstall OML4R Server from Oracle Database 12c and Earlier

To uninstall OML4R Server, run the server script with the --uninstall option.

You can perform either a full or a partial uninstall. A partial uninstall is performed by default.

WARNING:

Do not use the server.sh script to uninstall Oracle Machine Learning for R components from Oracle Database Release 18c or Release 19c. Doing so results in important files being deleted from the database. Instead, for an 18c or later database, use the rquncfg.sql script.

This topic has the following sections:

• Performing a Partial Uninstall
  A partial uninstall removes the RQSYS metadata and PL/SQL packages from the database but leaves the libraries and R packages that support OML4R Server in Oracle home.
• Performing a Full Uninstall
  A full uninstall removes the RQSYS schema metadata and PL/SQL code from the database and removes all OML4R Server libraries and R packages from Oracle home.
