Oracle cross-version migration using TTS

Others 2022-04-21 08:42:06 views: 0
TTS implements database migration and has the advantages of fast speed, cross-platform and cross-version support. This article documents the migration from 10g single to 11g RAC with TTS.
Source database version and character set settings: 
 
 
SQL> select * from v$version;

 1. Detect platform differences  
 
 
 source: 
 
 
 
 
 
SQL> SELECT d.PLATFORM_NAME, ENDIAN_FORMAT
2 FROM V$TRANSPORTABLE_PLATFORM tp, V$DATABASE d
3 WHERE tp.PLATFORM_NAME = d.PLATFORM_NAME;

PLATFORM_NAME ENDIAN_FORMAT
---------------------------------------- --------------
Linux x86 64-bit Little
 
 target： 
 
 
 
 
 
SQL> SELECT d.PLATFORM_NAME, ENDIAN_FORMAT
2 FROM V$TRANSPORTABLE_PLATFORM tp, V$DATABASE d
3 WHERE tp.PLATFORM_NAME = d.PLATFORM_NAME;

PLATFORM_NAME ENDIAN_FORMAT
---------------------------------------- ------------------------------------------
Linux x86 64-bit Little
 
 There is no difference between the two, and no platform format conversion is required.  
 
 
 
 
 2. Tablespace Self-Contained Detection  
 
 
 The tablespace for TTS must meet the self-contained conditions. If not, it needs to be adjusted until it is satisfied before TTS can be performed.  
 
 
 source: 
 
 
 
SQL> EXECUTE DBMS_TTS.TRANSPORT_SET_CHECK('tbs_postmall_data,tbs_postmall_idx', TRUE);

PL/SQL procedure successfully completed.

SQL> SELECT * FROM TRANSPORT_SET_VIOLATIONS;

no rows selected
 
 

 
 0 lines appear, indicating that the self-contained condition is satisfied.  
 
 
 
 
 3. Before Generate a Transportable Tablespace Set  
 
 
 generates a TTS set, you need to set the relevant tablespace to read only mode. 
 
 
 
 
 
SQL> alter tablespace tbs_postmall_data read only;

Tablespace altered.

SQL> alter tablespace tbs_postmall_idx read only;

Tablespace altered.
 
 Generate a metadata dumpfile of the relevant tablespace 
 
 
 
 
 
oracle@wls112:/data/oracle/dump> expdp system dumpfile=postmall_metadata.dmp directory=dump 
 
 
transport_tablespaces=tbs_postmall_data,tbs_postmall_idx logfile=tts_export.log;

 4. Transport the Tablespace Set  
 
 
 transfers the metadata dumpfile generated in the third step and the datafile of the related tablespace to the target side. The dumpfile is transferred to a directory on the target side, and the datafile is transferred to a temporary directory (target is ASM storage) or the datafile directory of the target database (target is file system storage).

 5. When transferring the datafile from the file system to ASM on the target side, the  
 
 
 asm cp command cannot be used directly for simple copying, but the convert datafile function in RMAN needs to be used to transfer the datafile

 , create the user first.

 7. Other objects imported by the user  
 
 
 cannot perform TTS because the system table is empty, so the objects of postmall_user in the system tablespace, such as sequences, PL/SQL packages, etc., cannot be migrated through TTS. So in the end, you need to use Data Pump to migrate other objects.

 The data are consistent, and there is no garbled characters in Chinese. Database migration was successful.  
 
 
 
 
 Summary: 
 
 
  1. The character sets (including NLS_CHARACTERSET and NLS_NCHAR_CHARACTERSET) of the databases on both sides should be exactly the same. If they are different, make sure that the character set of the source side is the true subset of the character set of the target side, and some restrictions must be added. For details, please refer to Instructions for official documentation.  
 
 
 2. Before generating and transmitting TTS Set on the source side, the related tablespace must be set to read only mode.  
 
 
 3. If you go from filesystem→filesystem, you can directly transfer the datafile to the datafile path of the target database. If you go from filesystem→asm, you need one more RMAN convert datafile operation. If it is asm→asm, it has not been tested yet.
