Since Pluggable Database is New Topic to post about , I Cannot post Everything in One Post so i decide
to do it as tutorial and this one part (3) , every Topics uploaded Here on my blog or on my Account on
Shareslide here.
In This topic:
 How to unplug database.
 Plugging Database to another Container Database.
Let's Start :
SQL> select name, con_id from v$active_services ;
NAME CON_ID
--------------------------------- ----------
new2 4
new 3
db12cXDB 1
db12c 1
SYS$BACKGROUND 1
SYS$USERS 1
As you see i already create two pluggable database new, new2 and now:
SQL> alter pluggable database new close immediate ;
Pluggable database altered.
SQL> alter pluggable database new2 close immediate ;
Pluggable database altered.
Unplug database included with xml file:
SQL> alter pluggable database new unplug into '/u01/app/oracle/oradata/new.xml';
Pluggable database altered.
SQL> alter pluggable database new2 unplug into '/u01/app/oracle/oradata/new_2.xml';
Pluggable database altered.

Drop Database:
SQL> drop pluggable database new keep datafiles ;
Pluggable database dropped.
SQL> drop pluggable database new2 keep datafiles ;
Pluggable database dropped.
Make sure you drop database:
SQL> select pdb_name, status from cdb_pdbs ;
PDB_NAME STATUS
----------- -------------
PDB$SEED NORMAL
Before Plug Database to any Container you need to make sure from compatibility, there's PL/SQL code
written by Oracle to check compatibility.
SQL > DECLARE
compatible BOOLEAN := FALSE;
BEGIN
compatible := DBMS_PDB.CHECK_PLUG_COMPATIBILITY(
pdb_descr_file => '/u01/app/oracle/oradata/new.xml');
if compatible then
DBMS_OUTPUT.PUT_LINE('Is pluggable PDB1 compatible? YES');
else DBMS_OUTPUT.PUT_LINE('Is pluggable PDB1 compatible? NO');
end if;
END;
/
Is pluggable PDB1 compatible? YES
PL/SQL procedure successfully completed.

The same will be for new2.xml
Now Let’s Create Database Using With Two Way:
SQL> create pluggable database newdb_plug using '/u01/app/oracle/oradata/new.xml' nocopy tempfile
reuse ;
Pluggable database created.
SQL> select pdb_name, status from cdb_pdbs;
PDB_NAME STATUS
------------------ -------------
NEWDB_PLUG NEW
PDB$SEED NORMAL
Another method to plug database:
SQL> create pluggable database new_plug_copy using '/u01/app/oracle/oradata/new_2.xml'
2 copy
3 FILE_NAME_CONVERT=('/u01/app/oracle/oradata/New2','/u01/app/oracle/oradata/new_plug_copy');
Pluggable database created.
SQL> select name,open_mode from v$pdbs;
NAME OPEN_MODE
------------------------------ ----------
PDB$SEED READ ONLY
NEWDB_PLUG MOUNTED
NEW_PLUG_COPY MOUNTED
Therefore
 Copy Clause :
o if you want the files listed in the XML file to be copied to the new location and used for
the new PDB.
 Nocopy Clause
o if you want the files for the PDB to remain in their current locations.

But what if i want to move all datafiles and create new pluggable database, oracle 12c provide you with
new clause to do this which is "move" check below:
SQL> create pluggable database new_plug_move using '/u01/app/oracle/oradata/new_2.xml'
2 move
3 FILE_NAME_CONVERT=('/u01/app/oracle/oradata/New2','/u01/app/oracle/oradata/move');
create pluggable database new_plug_move using '/u01/app/oracle/oradata/new_2.xml'
*
ERROR at line 1:
ORA-65122: Pluggable database GUID conflicts with the GUID of an existing container.
The above error is normal because i already create pluggable database using new_2.xml to solve it
SQL> create pluggable database new_plug_move as clone using '/u01/app/oracle/oradata/new_2.xml'
2 move
3 FILE_NAME_CONVERT=('/u01/app/oracle/oradata/New2','/u01/app/oracle/oradata/move');
Pluggable database created.
SQL> select pdb_name, status from cdb_pdbs;
PDB_NAME STATUS
------------------- -------------
NEWDB_PLUG NEW
PDB$SEED NORMAL
NEW_PLUG_COPY NEW
NEW_PLUG_MOVE NEW
You can open any database now and work on them.
Thank you
