Example 11-1 Unplugging PDB salespdb Into an XML Metadata File

This ALTER PLUGGABLE DATABASE statement unplugs the PDB salespdb and creates the salespdb.xml metadata file in the /oracle/data/ directory:

ALTER PLUGGABLE DATABASE salespdb UNPLUG INTO '/oracle/data/salespdb.xml';

Example 11-2 Unplugging PDB salespdb Into an Archive File

This ALTER PLUGGABLE DATABASE statement unplugs the PDB salespdb and creates the sales.pdb archive file in the /oracle/data/ directory. The sales.pdb archive file is a compressed file that includes the XML metadata file and the PDB’s files (such as the data files and wallet file).

ALTER PLUGGABLE DATABASE salespdb UNPLUG INTO '/oracle/data/sales.pdb';
