SUMMARY[edit]
This document describes the procedure required to migrate a database from Windows to Linux using the RMAN Convert Database command. Both Windows and Linux platforms have the same endian format, which makes possible to transfer the whole database, making the migration process very straightforward and simple. To migrate between platforms that have a different endian format, Cross Platform Transportable Tablespaces (XTTS) needs to be used instead. 2/32 The Windows Database This exercise was done using a small default 10.2.0.4 database SQL> select bytes,file_name from dba_data_files;

3/32 Database Migration From Windows to Linux Using RMAN List of Steps Needed to Complete the Migration The migration process is simple, but as it has several steps it is convenient to be familiar with them before running it. 1. CheckplatformcompatibilitybetweensourceandtargetOS 2. Startthedatabaseinreadonlymode 3. CheckdatabasereadinessfortransportfromWindowstoLinuxusingDBMS_TDB.CHECK_DB 4. Checkifthereareanyexternalobjects 5. ExecutetheRmanConvertdatabasecommand 6. Copyconverteddatafiles,generatedTransportScriptandParameterFiletoLinux 7. Edittheinit.oraforthenewdatabase 8.

ExecutetheTransportScript 10.Change the Database ID 11.Check database integrity 4/32 Database Migration From Windows to Linux Using RMAN 1. Check platform compatibility between source and target OS You need to check the platforms to be sure they have the same endian format, also you need to save the platform_name string to use it later as part of the convert database syntax in RMAN.

Using the RMAN CONVERT DATABASE Command Having executed successfully the checkup steps, the database is open in read only mode, then the convert database command can be executed with Rman. In this example, I’m not using the db_file_name_convert '<source-path> '<target-path>' option because the database is using oracle managed files (omf); when using omf Rman does generate and display the new file names on the output of the convert database command. At the end of the convert process Rman does display information about how to complete the conversion on the target platform.

Copy Converted Datafiles, Generated Transport Script and Parameter File to the Linux We need to copy over the generated files to the Linux server, they include all converted datafiles, the transport script and the generated pfile. If needed create at this point the directories you will need on the Linux server, for dump destination and flash recovery area i.e.:
mkdir –p
mkdir –p
mkdir –p
mkdir –p
mkdir –p
You can use ftp to copy the required files to the Linux server. In my test I will mount on the Linux server the directory for the new database, so I just move over the converted files to a predefined directory. All converted files have the string 44TM as part of their names, i.e.: O1_MF_SYSTEM_44TM3OPF_.DBF, then, while being at the datafiles location I do execute the move command to the new destination: /oradisk/oracle/app/admin/ORCLLNX/adump /oradisk/oracle/app/admin/ORCLLNX/bdump /oradisk/oracle/app/admin/ORCLLNX/cdump /oradisk/oracle/app/admin/ORCLLNX/udump /oradisk/database/ORCLLNX/FRA  G:\TECHNOLOGY\ORCLW\DATAFILE>move *44TM* ..\..\ORCLLNX

* Your database has been created successfully!
* There are many things to think about for the new database. Here
* is a checklist to help you stay on track:
* 1. You may want to redefine the location of the directory objects.
* 2. You may want to change the internal database identifier (DBID)
* or the global database name for this database. Use the
* NEWDBID Utility (nid).

26/32 Database Migration From Windows to Linux Using RMAN 10. Change database identifier To change the database identifier you need to use the NEWDBID utility “nid”. It is run from within Sqlplus having the database mounted:
sqlplus "/ as sysdba"
startup mount
exit
To change the DBID
cd $ORACLE_HOME/bin
./nid target=/
To verify the DBID and database name
SELECT dbid, name FROM v$_database;
DBID Change, Execution Log:
