TTS實現數據庫遷移，具有速度快、支持跨平臺和跨版本等優點。本文記錄了用TTS從10g single遷移到11g RAC的過程。 Source數據庫版本和字符集設置： SQL> select * from v$version; BANNER ---------------------------------------------------------------- Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bi PL/SQL Release 10.2.0.4.0 - Production CORE10.2.0.4.0 Production TNS for Linux: Version 10.2.0.4.0 - Production NLSRTL Version 10.2.0.4.0 - Production SQL> select * from nls_database_parameters where parameter in (‘NLS_CHARACTERSET‘,‘NLS_NCHAR_CHARACTERSET‘); PARAMETER VALUE ------------------------------ ------------------------------ NLS_CHARACTERSET UTF8 NLS_NCHAR_CHARACTERSET AL16UTF16 Target數據庫版本和字符集設置： SQL> select * from v$version; BANNER -------------------------------------------------------------------------------- Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production PL/SQL Release 11.2.0.3.0 - Production CORE 11.2.0.3.0 Production TNS for Linux: Version 11.2.0.3.0 - Production NLSRTL Version11.2.0.3.0 - Production SQL> select * from nls_database_parameters where parameter in (‘NLS_CHARACTERSET‘,‘NLS_NCHAR_CHARACTERSET‘); PARAMETER VALUE ------------------------------ -------------------- NLS_CHARACTERSET AL32UTF8 NLS_NCHAR_CHARACTERSET AL16UTF16 1、檢測平臺差異 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 兩者並無差異，無需進行平臺格式轉換。 2、Tablespace Self-Contained 檢測 進行TTS的表空間必須滿足自包含條件，如果不滿足，則需要進行調整直至滿足才可以進行TTS。 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 出現0行，說明滿足自包含條件。 3、Generate a Transportable Tablespace Set 生成TTS set之前，需要設置相關的表空間為read only模式。 SQL> alter tablespace tbs_postmall_data read only; Tablespace altered. SQL> alter tablespace tbs_postmall_idx read only; Tablespace altered. 生成相關表空間的metadata dumpfile 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; Export: Release 10.2.0.4.0 - 64bit Production on Thursday, 14 March, 2013 10:57:34 Copyright (c) 2003, 2007, Oracle.
