EF An XML metadata file describes the unplugged PDB and the files associated with the PDB (such as the data files and wallet file). An archive file includes both the XML metadata file and the PDB files. The USING clause of the CREATE PLUGGABLE DATABASE statement specifies a XML metadata file or a compressed archive file with a .pdb extension.
