RMAN : Cross-platform Database Transport Using RMAN Backup Image Copies

SCENARIO PREVIEW:

We will do cross platform migration of whole database using RMAN image backup  from linux to window Operating system.

There are 2 type of endian format Big and little

Database version : 12.2.0.1 

Endian format : Little

Cross platform migration : Linux to Window operating system

Source Database : Linux  (OEMDB )

Destination Database : Window (ORCL2 )

  • Open database in read only mode to make image backup in consistent mode.

SQL> select name,open_mode,database_role from v$database;

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

OEMDB     READ WRITE           PRIMARY

SQL> shutdown immediate;

Database closed.

Database dismounted.

ORACLE instance shut down.

SQL> startup mount;

ORACLE instance started.

SQL> alter database open read only;

  • Check database to be transported  to target platform

SQL> SET SERVEROUTPUT ON

ELSE

END IF;
