Oracle11gR2使用RMAN duplicate复制数据库——Backup-based database duplicate
本实例测试ORACLE 11g使用rman复制数据库。11g的RMAN duplicate 可以通过Active database duplicate和Backup-based duplicate两种方法实现。这里的测试使用的是Backup-based duplicate。 1、旧库或网络不可用，但是有备份 实验环境： target db： ip 192.168.56.10 oracle_sid=mydb oracle_version=11.2.0.3 auxiliary db： ip 192.168.56.150 oracle_sid=oradu oracle_version=11.2.0.3 1、备份target db RMAN> backup database include current controlfile plusarchivelog delete all input;
