PDB Creation with Various methods

In the next 2-3 posts we are going to see all the methods used to create Pluggable Database

There are following methods available to create Pluggable Database :

• Clone a regular PDB
• Create remote pdb using dblink
• Create a regular pdb to an application PDB
• Unplug and Plug a non-CDB
• Unplug and plug a regular PDB
• Unplug and plug an application container

1. Clone a regular PDB :

We can simply clone a regular Pluggable Database to create a new pluggable database.

I have one PDB created named PDBB121 and I want to create new PDB which should be a clone of PDB121 database.

Step 1: Connect to the CDB database

[oracle@localhost ~]$ sqlplus / as sysdba

SQL*Plus: Release 12.1.0.2.0 Production on Mon Jul 30 12:13:13 2018

Copyright (c) 1982, 2014, Oracle.  All rights reserved.


Connected to:
Oracle Database 12c Enterprise Edition Release 12.1.0.2.0 - 64bit Production
With the Partitioning, OLAP, Advanced Analytics and Real Application Testing options

SQL> select name,open_mode from v$database;

NAME	  OPEN_MODE
--------- --------------------
CDB121	  READ WRITE

Step 2: Check database which you want to create exist

SQL> show pdbs

    CON_ID CON_NAME			  OPEN MODE  RESTRICTED
---------- ------------------------------ ---------- ----------
	 2 PDB$SEED			  READ ONLY  NO
	 3 PDB121			  READ WRITE NO

Step 3: Clone database using create the pluggable database

SQL>  CREATE PLUGGABLE DATABASE CLONEPDB FROM PDB121 FILE_NAME_CONVERT=('/u02/oradata/cdb121/pdb121',
'/u02/oradata/cdb121/clonepdb');

Pluggable database created.

As I don’t have OMF enabled I need to pass the FILE_NAME_CONVERT parameter.

2.Create remote pdb using dblink

3. Clone a regular pdb to an application PDB :

4.Unplug and Plug a non-CDB

5.Unplug and plug a regular PDB

Step 1: Connect to CDB :

Step 2: shutdown pluggable database which you want to unplug and plug to another cdb.

SQL>alter pluggable database pdb1 close immediate;

Step 3: Unplug database using the following statement

SQL>  alter pluggable database pdb1 unplug into '/u02/pdb1.xml';

Pluggable database altered.

Step 4: Connect to Container database where you want to plug the pdb1 database.

Step 5: Create a pluggable database using the .xml file

SQL> create pluggable database app_pdb  using '/u02/pdb1.xml';

Pluggable database created.

6.Unplug and plug an application container

Unplug and plug application container
