RMAN CONVERT DATABASE 的限制

普通的RMAN DUPLICATE/RESTORE/RECOVER(非convert database 方式)  對平臺有一定的要求:



對於不滿足以上要求的需要使用CONVERT DATABASE 進行跨平臺遷移
但是也有一定的限制具體如下:
---必須有相同的endian format
   可以透過以下檢視查詢
   SQL> COLUMN PLATFORM_NAME FORMAT A32
SQL> SELECT * FROM V$TRANSPORTABLE_PLATFORM;
 
PLATFORM_ID PLATFORM_NAME                    ENDIAN_FORMAT
----------- -------------------------------- --------------
          1 Solaris[tm] OE (32-bit)          Big
          2 Solaris[tm] OE (64-bit)          Big
          7 Microsoft Windows IA (32-bit)    Little
         10 Linux IA (32-bit)                Little

官方文件說明:
The principal restriction on cross-platform. transportable database is that the source and destination platform. must share the same endian format. For example, while you can transport a database from Microsoft Windows to Linux for x86 (both little-endian), or from HP-UX to AIX (both big-endian), you cannot transport a whole database from HP_UX to Linux for x86 using this feature. You can, however, create a new database on a destination platform. manually, and transport needed tablespaces from the source database using cross-platform. transportable tablespace as described in "Cross-Platform. Tranportable Tablespace: CONVERT DATAFILE or TABLESPACE".

Also note that some parts of the database cannot be transported directly:

Redo log files and control files from the source database are not transported. New control files and redo log files are created for the new database during the transport process, and an OPEN RESETLOGS is performed once the new database is created.
Note:
The control file for the converted database does not contain a copy of the RMAN repository information from the source database. Backups from the source database cannot be used with the converted database.
BFILEs are not transported. RMAN provides a list of objects using the BFILE datatype in the output for the CONVERT DATABASE command, but users must copy the BFILEs themselves and fix their locations on the destination database.

Tempfiles belonging to locally managed temporary tablespaces are not transported. The temporary tablespace will be re-created on the target platform. when the transport script. is run.

External tables and directories are not transported. RMAN provides a list of affected objects as part of the output of the CONVERT DATABASE command, but users must redefine these on the destination platform. See Oracle Database Administrator's Guide for more information on managing external tables and directories.

Password files are not transported. If a password file was used with the source database, the output of CONVERT DATABASE includes a list of all usernames and their associated privileges. Create a new password file on the destination database using this information. See Oracle Database Security Guide for more information on managing password files.
