hp-ux利用rman將資料庫跨平臺遷移到aix平臺上
這次因為要遷移的資料庫大小並不大但也不是隻有幾十G所以選擇使用rman將生產資料庫從hp-ux遷移到aix上，資料庫是10.2.0.4
1.操作環境
1.1 源生產環境
資料庫名 CAIWU
例項名 CAIWU
DBID 338270341
資料庫 HP-UX 10.2.0.4.0 - 64bit Production
資料檔案目錄 /cwjc_data/CAIWU
文字初始化引數檔案:/oracle/product/10.2.0/dbs/init/initCAIWU.ora
1.2 目標生產環境
資料庫名 CAIWU
例項名 CAIWU
DBID 338270341
資料庫 HP-UX 10.2.0.4.0 - 64bit Production
資料檔案目錄 /yl_oradata/CAIWU
文字初始化引數檔案:/oracle/product/10.2.0/db_1/dbs/init/initCAIWU.ora
2 備份
2.1 備份注意事項
1. 遷移庫只能在同位元組順序平臺之間(即ENDIAN_FORMAT相同)且得是ORACLE所支援的平臺，可以在V$TRANSPORTABLE_PLATFORM中檢視。
2. 傳輸前需要將源庫置為只讀。
3. 生成的2個指令碼檔案要仔細根據需要修改。
2.2 源庫操作
2.2.1 將庫只讀，並檢查是否支援遷移
一．將庫只讀，並檢查是否支援遷移

2.2.3 利用dbms_tdb 包檢查資料庫
二．利用dbms_tdb 包檢查資料庫能否被傳輸以及列出外部表和DIRECTORY 等無法傳輸的物件資訊，
分別在hp-ux平臺資料庫透過SQLPLUS執行以下兩個儲存過程
SQL> set serveroutput on
SQL> declare
2 db_ready boolean;
3 begin
4 /* db_ready is ignored, but with SERVEROUTPUT set to ON any
5 * conditions preventing transport will be output to console */
6 db_ready := dbms_tdb.check_db('AIX-Based Systems (64-bit)',
7 dbms_tdb.skip_none);
8 end;
9 /
PL/SQL procedure successfully completed.
SQL> declare

The following directories exist in the database:
SYS.DUMP_CAIWU, SYS.DATA_PUMP_DIR, SYS.WORK_DIR, SYS.ADMIN_DIR, SYS.ORACLE_OCM_CONFIG_DIR

將init_00pjoiqb_1_0.ora引數檔案複製到$ORACLE_HOME/dbs目錄下
[IBMP740-2:oracle:/yl_oradata/CAIWU]$ cp init_00pjoiqb_1_0.ora $ORACLE_HOME/dbs
2.2.5 在目標生產機器上修改pfile引數檔案並將引數檔案init_00pjoiqb_1_0.ora重新命名為initCAIWU.ora
IBMP740-2:oracle:/oracle/product/10.2.0/db_1/dbs]$mv init_00pjoiqb_1_0.ora initCAIWU.ora
修改前引數檔案內容如下:
[IBMP740-2:oracle:/oracle/product/10.2.0/db_1/dbs]$vi initCAIWU.ora "initCAIWU.ora" 68 lines, 1556 characters __shared_pool_size = 2164260864 __large_pool_size = 16777216 __java_pool_size = 16777216 __streams_pool_size = 150994944 __db_cache_size = 1073741824 # Please change the values of the following parameters: control_files ="/yl_oradata/CAIWU/control01.ctl","/yl_oradata/CAIWU/control02.ctl","/yl_oradata/CAIWU/control03.ctl" db_recovery_file_dest = "/oracle/flash_recovery_area" db_recovery_file_dest_size= 2147483648 background_dump_dest = "/oracle/admin/CAIWU/bdump" user_dump_dest = "/oracle/admin/CAIWU/udump" core_dump_dest = "/oracle/admin/CAIWU/cdump" audit_file_dest = "/oracle/admin/CAIWU/adump" db_name = "CAIWU" # Please review the values of the following parameters: remote_login_passwordfile= "EXCLUSIVE" db_domain = "" dispatchers = "(PROTOCOL=TCP) (SERVICE=CAIWUXDB)" # The values of the following parameters are from source database: processes = 500 sessions = 555 sga_target = 3439329280 db_block_size = 8192 compatible = "10.2.0.3.0" # log_archive_dest_1 = "LOCATION=/yl_oradata/arch/CAIWU/" log_archive_format = "%t_%s_%r.dbf" db_file_multiblock_read_count= 16 undo_management = "AUTO" undo_tablespace = "UNDOTBS1" job_queue_processes = 10 open_cursors = 300 pga_aggregate_target = 858783744
修改後引數檔案內容如下:

2.2.6 修改重建控制檔案的指令碼caiwu.sql
修改後的caiwu.sql內容如下:

小結
1. 確保源庫與目標資料庫的字符集一致
2. 要確保源庫與目標資料庫的位元組編碼相同
3. 資料庫遷移後要把無效的資料庫物件重新編譯，確保正確執行utlrp.sql,utlirp.sql
4. 資料庫遷移後，確保應用系統使用者可以正確連線，登陸有效
5. 監聽要重新配置，檢查臨時表空間的屬主與可用性
6. 遷移完成後要立即進行一次全備份
