You can install Oracle R Enterprise Server in one or more pluggable databases (PDBs) within a multitenant environment. Oracle R Enterprise Server must be installed in a pluggable database, not in the root database.
If you have more than one instance of Oracle R Enterprise Server installed in a Multitenant Container Database (CDB) and you want to uninstall one instance but retain the others, you can perform a partial uninstall as described in Performing a Partial Uninstall.
