When you drop a PDB, the control file of the multitenant container database (CDB) is modified to remove all references to the dropped PDB and its data files. A PDB can either have its owner temporary tablespace, or if it is created without a temporary tablespace, it can share the temporary tablespace with the CDB.

The following statement plugs in the PDB: You can unplug an application container from a CDB. When you specify a .pdb file, it contains a compressed archive of the XML file that describes the application seed and the files used by the application seed (such as the data files and wallet file).
