 Unplugging the PDB

To unplug a PDB, you first close it and then generate an XML manifest file. The XML file contains information about the names and the full paths of the tablespaces, as well as data files of the unplugged PDB. The information will be used by the plugging operation.

 


SQL> alter pluggable database BSNL close;

 

Pluggable database altered.

 

Unplug the closed PDB 

 

SQL> alter pluggable database BSNL unplug into '/home/oracle/bsnl.xml';

 

Pluggable database altered.

 


Verify the status of the unplugged PDB

 

SQL> select pdb_name, status from cdb_pdbs where pdb_name in ('BSNL');

 

PDB_NAME

--------------------------------------------------------------------------------

STATUS

----------

BSNL

UNPLUGGED

Plugging the PDB

SQL> create pluggable database "BSNL" using '/home/oracle/bsnl.xml' nocopy tempfile reuse;

 

Pluggable database created.

 


 Verify the status of the unplugged PDB


SQL> select pdb_name, status from cdb_pdbs where pdb_name in ('BSNL');

 

PDB_NAME                      STATUS

--------------------------------------------------------

BSNL                                NORMAL
