記一次oracle 通過手動xtts的方法從WINDOW遷移到LINUX（一）
基本資訊*
| IP | 作業系統 | 資料庫版本 | 資料庫資訊 | |
|---|---|---|---|---|
| 源端 | 10.10.41.85 | windows | oracle11.2.04 | test(這裡用TEST代替真正的SID) |
| 目標端 | 10.10.41.50 | centos7.6 | oracle11.2.04 | test(這裡用TEST代替真正的SID) |
測試目的:
檢查確認TEST（這裡TEST代替資料庫名）從WINDOWS遷移到LINUX是否具有可行性。
這裡通過手動XTTS的方法進行遷移，由於XTTS的PERL指令碼不支援源服務端為WINDOWS，所以這裡用手動XTTS（RMAN備份集方式）。
遷移前檢查
1.檢查平臺
SELECT PLATFORM_id,PLATFORM_NAME, ENDIAN_FORMAT
FROM V$TRANSPORTABLE_PLATFORM
WHERE PLATFORM_ID =
( SELECT PLATFORM_ID
FROM V$DATABASE );
2.檢查字符集
select * from nls_database_parameters where parameter='NLS_CHARACTERSET';
3檢查時區
select dbtimezone from dual;
4.檢查命令進行自包含檢查(重點）
exec sys.dbms_tts.transport_set_check('TEST_INDEX,TEST1_INDEX,TEST2_DATA,TEST3_DATA,TEST4_DATA,TEST3_INDEX',TRUE);
select select * from TRANSPORT_SET_VIOLATIONS;
開始遷移
1.在源端 （進行全備份）
RMAN TARGET /
run{
allocate channel t1 type disk;
backup incremental level=0 tablespace TEST_INDEX,TEST1_INDEX,TEST2_DATA,TEST3_DATA,TEST4_DATA,TEST3_INDEX
format 'I:\pglng-backup\rman\TESTtbs0_%U'tag=TESTtbs0;
release channel c1;
}
2.在目的端進行全量恢復
DECLARE
devtype varchar2(256);
done Boolean;
BEGIN
Devtype:=sys.dbms_backup_restore.deviceAllocate(type=>'',ident=>'t1');
sys.dbms_backup_restore.restoreSetDatafile;
sys.dbms_backup_restore.restoreDatafileTo(dfnumber=>05,toname=>'/data/test/test1_INDEX.DBF');
sys.dbms_backup_restore.restoreDatafileTo(dfnumber=>06,toname=>'/data/test/test2_INDEX.DBF');
sys.dbms_backup_restore.restoreDatafileTo(dfnumber=>07,toname=>'/data/test/test3_DATA.DBF');
sys.dbms_backup_restore.restoreDatafileTo(dfnumber=>08,toname=>'/data/test/test1_DATA.DBF');
sys.dbms_backup_restore.restoreDatafileTo(dfnumber=>09,toname=>'/data/test/test2_DATA.DBF');
sys.dbms_backup_restore.restoreDatafileTo(dfnumber=>10,toname=>'/data/test/test3_INDEX.DBF');
sys.dbms_backup_restore.restoreBackupPiece(done=>done,handle=>'/u01/rman/leve0/testTBS0_0HV7GF2Q_1_1',params=>null);
sys.dbms_backup_restore.deviceDeallocate;
END;

進行資料庫割接
把要遷移表空間設為只讀狀態
alter tablespace exessa_data readonly;
alter tablespace exessa_index readonly;
alter tablespace appquery_data readonly;
alter tablespace appquery_index readonly;
alter tablespace fullquery_data readonly;
alter tablespace fullquery_index readonly;
最後增量備份（注最後增量備份前必須把表空間置為只讀，不然最後匯入元資料會報錯）
rman target /
run{
backup incremental level=1 tablespace test1_INDEX,test2_INDEX,test2_DATA,test1_DATA,test3_DATA,test3_INDEX
format 'I:\pglng-backup\rman\testtbs1_%U'tag=testtbs1;
}
