Oracle 12c Database: Cloning PDB using SQL Developer

How to clone a PDB1 database using of SQL Developer

Modify the State to Read Only (If Open then Shutdown and Open in Read Only mode)


Use the Clone Pluggable Database Option

First you have to shutdown the PDB1 database.

 

See the status of PDB1.

 Start database read only mode.

 Right click on PDB1 database and select the Clone Pluggable database option.

 Change the Database Name: NEW_PDB & Select the File Name Conversion option.

Goto to SQL tab and change the Clone database files path.

Clone database created.

You can start the clone NEW_PDB database.

Create the new connection for "test" user which ready created in PDB1.

Verify the data in NEW_PDB database.

 

Now you start the PDB1 database for normal operation.

Oracle 12c: Opening a PDB Using SQL Developer

You can open Pluggable database using SQL Deverloper

Make a connection to the CDB and using the DBA view expand the container database.

Select the PDB1 database

 Right click on PDB1 & Select the Modify State.

Select the READ ONLY.

You can see the Status of PDB1 database. (Read Only)

Create user for testing....You are getting error because PDB1 database read only mode.

Now you start the PDB1 database.

 

Oracle 12c Database Enable Archive Log Mode for CDB using SQL Developer

Enable Archive Log Mode using SQL Developer

Enable the Archive mode

Edit the Listener.ora file.

\

Verifying if Archiver is started in CDB1

Verifying if Archiver is started in all pluggable databases like  PDB1 

Oracle 12c Database Recovering Pluggable Database

Oracle 12c Database Online Move Datafile

Prior to Oracle 12c, if you wanted to move a database’s file, you either had to shutdown the database, or take the datafile/tablespace offline. Here is an example of the steps you might take

SQL> ALTER TABLESPACE test OFFLINE;

SQL> !mv  /ora/test1/test01.dbf    /ora/test2/test01.dbf

SQL> ALTER DATABASE RENAME FILE ‘/ora/test1/test01' TO ‘/ora/test2/test01.dbf’;

SQL>ALTER TABLESPACE test ONLINE;

The good news is that Oracle 12cR1 now offers the ability to move entire datafiles between different storage locations without ever having to take the datafiles offline. The datafiles being moved remain completely accessible to applications in almost all situations, including querying against or performing DML and DDL operations against existing objects, creating new objects, and even rebuilding indexes online. Online Move Datafile (OMD) also makes it possible to migrate a datafile between non-ASM and ASM storage (or vice-versa) while maintaining transparent application access to that datafile’s underlying database objects. OMD is completely compatible with online block media recovery, the automatic extension of a datafile, the modification of a tablespace between READ WRITE and READ ONLY mode, and it even permits backup operations to continue against any datafiles that are being moved via this feature.
