RMAN實戰系列之一：用duplicate複製資料庫

源平臺：

windows 2000

hostname=host1

ORACLE_BASE=e:oracle

目標平臺：

windows 2000

hostname=host2

ORACLE_BASE=d:oracle

db_name=hyb

資料庫版本：Oracle 9.0.1

目的：在host2上覆制host1的資料庫

1.       假定在host2上已經安裝好了資料庫軟體，以OFA的結構建立新資料庫的目錄架構，把host1上的初始化引數檔案複製到host2上，修改以下引數：

control_files/user_dump_dest/ background_dump_dest/ core_dump_dest

以及其他必須的引數。如

background_dump_dest=D:oracleadminhybbdump

core_dump_dest=D:oracleadminhybcdump

user_dump_dest=D:oracleadminhybudump

control_files=("D:oracleoradatahybCONTROL01.CTL", "D:oracleoradatahybCONTROL02.CTL", "D:oracleoradatahybCONTROL03.CTL")

用oradim建立windows服務：

oradmin –new –sid hyb –pfile d:oracleadminhybpfileinit.ora

用orapwd建立密碼檔案：

orapwd file=d:oracleora90databasepwdhyb.ora password=oracle entries=5

2.       啟動sqlplus，建立spifle，並startup到nomount狀態

create spfile from pfile=’ d:oracleadminhybpfileinit.ora’;

startup nomount;

    3.       在host1上全備份資料庫和歸檔日誌

rman>configure channel device type disk format “e:rman%t%U.bak”;

rman>backup database plus archivelog;

4.       在host2上e盤中建立rman目錄，把host1上的rman全備份複製到host2對應的rman目錄上。

5.       由於host2的目錄結構與host1不一致，使用SET NEWNAMW改變資料檔案的路徑，使用logfile子句修改重做日誌檔案的位置。

6.       啟動rman，連線到目標資料庫、恢復目錄資料庫和輔助資料庫。

7.       用命令DUPLICATE探測資料檔案的位置，使用rman提示符中顯示的指令碼：

rman>duplicate target database to hyb logfile 'D:ORACLEoradatahyb redo01.log' size 10m, 'D:ORACLEoradatahybredo02.log' size 10m nofilenamecheck;

上述命令會出錯：

RMAN-10035: exception raised in RPC: ORA-19624: 操作失敗，如果可能請重試

ORA-19504: 無法建立檔案"E:ORACLEORADATASIMISSIDB_RBS.ORA"

ORA-27040: skgfrcre: 建立錯誤，無法建立檔案

OSD-04002: 無法開啟檔案

O/S-Error: (OS 3) 系統找不到指定的路徑。

ORA-06512: 在"SYS.X$DBMS_BACKUP_RESTORE", line 1358

RMAN-10031: ORA-19624 occurred during call to DBMS_BACKUP_RESTORE.RESTOREBACKUPPIECE

無需理會，需要的是其中的指令碼：
