Oracle 10g Linux 单实例迁移 到 Oracle 10g rac 简要操作说明

1.从源端单实例数据库rman备份

包括：控制文件+归档+数据+pfile.ora

2.rac搭建，不需要创建实例

3.修改配置文件，先恢复单实例数据

sqlplus / as sysdba

STARTUP NOMOUNT pfile='/u01/oracle/backup/pfile.ora';

$ORACLE_HOME/bin/rman target /

restore controlfile from '/u01/oracle/backup/Oracle_20121012_LEVEL_0_CONTROLFILE_0_40.rman';

sqlplus / as sysdba

SQL> alter database mount;

Database altered.

SQL> select name from v$datafile;
