在oracle10gR2中，oracle開始支持同字節(jié)序數(shù)據(jù)庫(kù)的跨平臺(tái)遷移，下面將linux下的數(shù)據(jù)庫(kù)遷移到windows。
Oracle 10g同字節(jié)序跨平臺(tái)遷移的測(cè)試
在oracle10gR2中，oracle開始支持同字節(jié)序數(shù)據(jù)庫(kù)的跨平臺(tái)遷移，
下面將linux下的數(shù)據(jù)庫(kù)遷移到windows。
這一技術(shù)實(shí)現(xiàn)有以下幾點(diǎn)注意事項(xiàng)：
1、 源平臺(tái)和目標(biāo)平臺(tái)需要具有相同的字節(jié)序
2、 重做日志文件和控制文件不會(huì)傳輸，遷移之后需要重建控制文件使用resetlogs的方式打開數(shù)據(jù)庫(kù)
3、 臨時(shí)文件不會(huì)被傳輸
4、 BFILE、外部表和Directories、口令文件不會(huì)被傳輸
1，確認(rèn)平臺(tái)及版本，看到源平臺(tái)和目標(biāo)平臺(tái)具有相同的字節(jié)序
SQL> column PLATFORM_NAME format a50
SQL> select PLATFORM_NAME, ENDIAN_FORMAT from v$transportable_platform
2 where platform_name in(’Linux IA (32-bit)’,’Microsoft Windows IA (32-bit)’);
PLATFORM_NAME ENDIAN_FORMAT
-------------------------------------------------- ----------------------------
Microsoft Windows IA (32-bit) Little
Linux IA (32-bit) Little
2，確認(rèn)遷移是否支持,linux的數(shù)據(jù)庫(kù)需處于read only模式打開，使用dbms_tdb.check_db進(jìn)行檢查
SQL> shutdown immediate;
SQL> startup mount
SQL> alter database open read only;
SQL> set serveroutput on
SQL> declare
2 db_ready boolean;
3 begin
4 db_ready:=dbms_tdb.check_db(’Microsoft Windows IA (32-bit)’);
5 end;
6 /
PL/SQL procedure successfully completed.
3，檢查外部對(duì)象，使用dbms_tdb.check_external來(lái)識(shí)別外部表、Directories或BFILES等，這些對(duì)
象所指向的外部數(shù)據(jù)不能被RMAN自動(dòng)轉(zhuǎn)移。
SQL> declare
2 external boolean;
3 begin
4 external:=dbms_tdb.check_external;
5 end;
6 /
The following directories exist in the database:
SYS.ADMIN_DIR, SYS.WORK_DIR, SYS.DATA_PUMP_DIR
PL/SQL procedure successfully completed.
4，使用RMAN進(jìn)行跨平臺(tái)文件遷移。執(zhí)行跨平臺(tái)遷移首先要通過(guò)RMAN對(duì)數(shù)據(jù)文件進(jìn)行轉(zhuǎn)移：

Edit init.ora file /oracle/product/10.2.0/dbs/init_00j64gcv_1_0.ora. This PFILE will be used to create the database on the target platform
To recompile all PL/SQL modules, run utlirp.sql and utlrp.sql on the target platform

先將控制文件的內(nèi)容給注釋掉，待建好控制文件后再改成正確的。
修改的參數(shù)文件如下 ：
# Please change the values of the following parameters:

最后不要忘記增加臨時(shí)文件
SQL> ALTER TABLESPACE TEMP ADD TEMPFILE ’D:oracleproduct10.2.0oradatalisad
