在oracle10gR2中，oracle開始支持同字節(jié)序數(shù)據(jù)庫的跨平臺遷移，下面將linux下的數(shù)據(jù)庫遷移到windows。
Oracle 10g同字節(jié)序跨平臺遷移的測試
在oracle10gR2中，oracle開始支持同字節(jié)序數(shù)據(jù)庫的跨平臺遷移，
下面將linux下的數(shù)據(jù)庫遷移到windows。
這一技術(shù)實(shí)現(xiàn)有以下幾點(diǎn)注意事項(xiàng)：
1、 源平臺和目標(biāo)平臺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
3、 臨時(shí)文件不會被傳輸
4、 BFILE、外部表和Directories、口令文件不會被傳輸
1，確認(rèn)平臺及版本，看到源平臺和目標(biāo)平臺具有相同的字節(jié)序
SQL> column PLATFORM_NAME format a50
SQL> select PLATFORM_NAME, ENDIAN_FORMAT from v$transportable_platform
2 where platform_name in(’Linux IA (32-bit)’,’Microsoft Windows IA (32-bit)’);
PLATFORM_NAME ENDIAN_FORMAT
-------------------------------------------------- ----------------------------
Microsoft Windows IA (32-bit) Little
Linux IA (32-bit) Little
2，確認(rèn)遷移是否支持,linux的數(shù)據(jù)庫需處于read only模式打開，使用dbms_tdb.check_db進(jìn)行檢查
SQL> shutdown immediate;
SQL> startup mount
SQL> alter database open read only;
SQL> set serveroutput on
SQL> declare
2 db_ready boolean;
3 begin
4 db_ready:=dbms_tdb.check_db(’Microsoft Windows IA (32-bit)’);
5 end;
6 /
PL/SQL procedure successfully completed.
3，檢查外部對象，使用dbms_tdb.check_external來識別外部表、Directories或BFILES等，這些對
象所指向的外部數(shù)據(jù)不能被RMAN自動(dòng)轉(zhuǎn)移。
SQL> declare
2 external boolean;
3 begin
4 external:=dbms_tdb.check_external;
5 end;
6 /
The following directories exist in the database:
SYS.ADMIN_DIR, SYS.WORK_DIR, SYS.DATA_PUMP_DIR
PL/SQL procedure successfully completed.
4，使用RMAN進(jìn)行跨平臺文件遷移。執(zhí)行跨平臺遷移首先要通過RMAN對數(shù)據(jù)文件進(jìn)行轉(zhuǎn)移：
[oracle@linx130 orcl]$ rman target /

修改參數(shù)文件，參數(shù)文件可以從前面自動(dòng)生成的參數(shù)文件中修改得到，傳輸過程略，放在D:oracleproduct10.2.0adminlisapfile下面，文件名改成init.ora
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:
# control_files = "/oracle/product/10.2.0/dbs/cf_D-LISA_id-1171353837_00j64gcv"
db_recovery_file_dest = "D:oracleproduct10.2.0adminlisaflash_recovery_area"

SQL> startup mount pfile=’D:oracleproduct10.2.0adminlisapfileinit.ora’

SQL> alter database open resetlogs;

由于源平臺和目標(biāo)平臺的oracle版本相同，打開比較順利，沒有出現(xiàn)需要升級的提示
建立spfile
SQL> create spfile from pfile=’D:oracleproduct10.2.0adminlisapfileinit.ora’;

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

Tablespace altered.
