RMAN - Cross Platform Migration using Transport Tablespace using Expdp | Impdp backup

Scenario Preview:

We will do cross platform migration of tablespace using impdp from linux OS to window OS.

There are 2 type of endian format Big and little  Below list we can find out endian format using table view V$TRANSPORTABLE_PLATFORM;



Database version : 12.2.0.1 

Endian format : Little

Cross platform migration : Linux to Window operating system

Source Database : Linux  (OEMDB database )

Destination Database : Window (ORCL database)

KEYWORDS:

View Name : V$TRANSPORTABLE_PLATFORM

 Package : exec DBMS_TTS.TRANSPORT_SET_CHECK('MGMT_TABLESPACE', TRUE,TRUE);

Table Name : TRANSPORT_SET_VIOLATIONS

EXPDP: transport_tablespaces=MGMT_TABLESPACE,MGMT_ECM_DEPOT_TS,MGMT_AD4J_TS

RMAN:CONVERT DATAFILE

IMPDP : transport_datafiles




  • Check tablespace name from sysman user

SQL> select USERNAME,ACCOUNT_STATUS,DEFAULT_TABLESPACE from dba_users where username='SYSMAN';

---------------------------------------- -------------------------------- ------------------------------
SYSMAN                                   OPEN                             MGMT_TABLESPACE

  • We are using transport tablespace from linux to window Endian platform from  V$TRANSPORTABLE_PLATFORM

SQL> SELECT PLATFORM_NAME, ENDIAN_FORMAT FROM V$TRANSPORTABLE_PLATFORM WHERE UPPER(PLATFORM_NAME) LIKE '%LINUX%X86%64-BIT%' OR UPPER(PLATFORM_NAME) LIKE '% WINDOWS%X86%64-BIT%';

PLATFORM_NAME                                                                                         ENDIAN_FORMAT

Microsoft Windows x86 64-bit                                                                Little
  • Endian Platform check on destination  window database
SQL> select name,open_mode,database_Role from v$database;

--------- -------------------- ----------------
ORCL      READ WRITE           PRIMARY


SQL>  SELECT PLATFORM_NAME, ENDIAN_FORMAT FROM V$TRANSPORTABLE_PLATFORM WHERE UPPER(PLATFORM_NAME) LIKE '%LINUX%X86%64-BIT%' OR UPPER(PLATFORM_NAME) LIKE '% WINDOWS%X86%64-BIT%';

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

Microsoft Windows x86 64-bit             Little

  • Check the tablespace transported is self contained  Check violations it should return no rows. check user list of violations. Below examples we can see some multiple violations. Fix it before proceed.
