7 Removing Oracle Database Software

Use the deinstall command that is included in Oracle homes to remove Oracle software. Oracle does not support the removal of individual products or components.

Caution:

If you have a single-instance database on a node in a cluster, and if you have multiple databases with the same global database name (GDN), then you cannot use the deinstall command to remove one database only.
