配置RAC+DG的过程简述
（1）RMAN备份主库（全库备份，包括归档日志）。将RMAN备份，pfile参数文件，密码文件，standby控制文件拷贝至备库。
（2）在备库修改pfile参数文件，用RMAN在nomount状态下恢复standby控制文件，mount状态恢复数据库。
（3）备库开启日志应用
（4）修改主库参数（为failover或switchover准备）
具体步骤
（0）前期检查，查看数据库监听情况，及tnsnames.ora配置。

（1）将RAC主库修改为归档模式，并开启force logging模式。
由于事先已经将数据库置为归档模式，故在此只需要修改force logging模式即可。

（2）主库全备，创建standby control file，生成pfile文件，复制密码文件。然后将准备好的所有文件复制到备库所在目录（最好对应主库的备份目录，方便RMAN恢复。）
