Drop Pluggable Database

Use this dialog box to drop a PDB.

Database Name: Name of the PDB.

Datafile Action: Determines whether to retain or delete the data files associated with the PDB after the PDB is dropped.

Keep: Retains the data files associated with the PDB after the PDB is dropped. The temp file for the PDB is deleted because it is no longer needed. Keeping data files may be useful in scenarios where a PDB that is unplugged from one CDB is plugged into another CDB, with both CDBs sharing storage devices.
Including: Deletes the data files associated with the PDB being dropped. The temp file for the PDB is also deleted. (Including must be specified if the PDB was created with the SNAPSHOT COPY clause)
