Clone An Instance

概要

操作系统感染病毒导致瘫痪，不得已重新安装了WindowsXP。原有系统中安装有Oracle10g，为了
恢复原有的数据库，在新的操作系统中进行了如下的操作。

Step 1：安装Oracle10g软件

备考： 安装路径中包含原来Oracle10g的安装文件，所以Oracle10g的重新安装在1分钟之内就结束了。

Step 2: 建立一个ORACLE_SID是ZQ03的空闲例程

oradim -new -sid ZQ03 -pfile F:\oracle\product\10.2.0\db_1\database\initZQ03.ora

备考： 利用了原有的initZQ03.ora作为pfile参数文件。
空闲例程建立后，在管理工具的服务中确认空闲例程已经启动。

Step 3：建立数据库密码文件

orapwd file=F:\oracle\product\10.2.0\db_1\database\PWDZQ03.ora password=oracle 
entries=5

备考： 原有的PWDZQ03.ora文件已经存在，因此省略了这步操作。

Step 4：启动Oracle监听服务

lsnrctl start

备考： 在管理工具的服务中确认监听服务已经启动。

Step 5：设置ORACLE_SID环境变量

set ORACLE_SID=ZQ03

Step 6：启动ZQ03instance

sqlplus "/ as sysdba"
    startup pfile=F:\oracle\product\10.2.0\db_1\database\initZQ03.ora nomount
    alter database mount;
    alter database open;

至此，原有的ZQ03例程重新启动成功，接下来利用ZQ03克隆一个SID为ZQ04的新历程。
利用rman克隆数据库之前，先取得一份ZQ03的全备份

rman target system/manager@ZQ03 nocatalog
    backup full database;
    sql 'alter system archive log current';
    backup archivelog all delete input;
    backup current controlfile;
    exit;

Step 1: 建立一个ORACLE_SID是ZQ04的空闲例程

oradim -new -sid ZQ04

Step 2：建立数据库密码文件

orapwd file=F:\oracle\product\10.2.0\db_1\database\PWDZQ04.ora password=oracle entries=5

Step 3：设置ORACLE_SID环境变量

set ORACLE_SID=ZQ04

Step 4：装载ZQ04空闲例程

sqlplus "/ as sysdba"
    startup pfile=F:\oracle\product\10.2.0\db_1\database\initZQ04.ora nomount

++Step 5：克隆ZQ03到ZQ04

rman target system/manager@zq03 auxiliary system/manager@zq04 nocatalog
RUN
{
set newname for datafile 3 to 'F:\oracle\product\10.2.0\oradata\ZQ04\SYSAUX01.DBF';
set newname for datafile 1 to 'F:\oracle\product\10.2.0\oradata\ZQ04\SYSTEM01.DBF';
set newname for datafile 2 to 'F:\oracle\product\10.2.0\oradata\ZQ04\UNDOTBS01.DBF';
set newname for datafile 4 to 'F:\oracle\product\10.2.0\oradata\ZQ04\USERS01.DBF';
set newname for tempfile 1 to 'F:\oracle\product\10.2.0\oradata\ZQ04\TEMP01.DBF';
DUPLICATE TARGET DATABASE TO ZQ04
LOGFILE
GROUP 1
(
'F:\oracle\product\10.2.0\oradata\ZQ04\REDO01_A.LOG',
'F:\oracle\product\10.2.0\oradata\ZQ04\REDO01_B.LOG'
) SIZE 50M,
GROUP 2
(
'F:\oracle\product\10.2.0\oradata\ZQ04\REDO02_A.LOG',
'F:\oracle\product\10.2.0\oradata\ZQ04\REDO02_B.LOG'
) SIZE 50M,
GROUP 3
(
'F:\oracle\product\10.2.0\oradata\ZQ04\REDO03_A.LOG',
'F:\oracle\product\10.2.0\oradata\ZQ04\REDO03_B.LOG'
) SIZE 50M;
}

备考： 上面的脚本中需要通过set newname命令修改数据文件的路径，对应文件名称不要出错。
用set newname for tempfile命令修改临时表领域文件的路径。
克隆数据库时候通过LOGFILE字句重建ZQ04的在线REDO日志文件
下面是rman脚本执行后的输出结果
