Oracle 11gR2使用RMAN duplicate复制数据库——active database duplicate

Oracle 11gR2的RMAN duplicate 个人感觉比10g的先进了很多，10g需要在rman备份的基础上进行复制，使用 RMAN duplicate 创建一个数据完全相同但DBID不同的数据库。而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Active database duplicate，因为Active database duplicate 功能强大，不需要先把目标数据库进行rman备份，只要目标数据库处于归档模式下即可直接通过网络对数据库进行copy，且copy完成后自动open数据库。这对于大数据特别是T级别的数据库来说优点非常明显，复制前不需要进行备份，减少了备份和传送备份的时间，同时节省备份空间。下面来进行具体的duplicate操作。应用场景：1、旧库可以使用并且网络顺畅实验环境：target db：ip 192.168.56.10oracle_sid=mydboracle_version=11.2.0.3auxiliary db：ip 192.168.56.150oracle_sid=oraduoracle_version=11.2.0.31、在新库创建参数文件并启动实例到nomount状态--auxiliary db上执行[oracle@localhost ~]$ cat initoradu.oradb_name=oradudb_block_size=8192db_file_name_convert=（"/u01/app/oracle/oradata/mydb/","/u01/app/oracle/oradata/oradu/"）log_file_name_convert=（"/u01/app/oracle/oradata/mydb/","/u01/app/oracle/oradata/oradu/"）--由于这里使用的是不同实例，所以必须添加db_file_name_convert和log_file_name_convert，否则在复制的时候会报错无法创建数据文件，如果是同实例名复制，且两数据目录完全一样的情况下，这两个参数可省略。--在auxiliary db 上创建新库的数据文件在存放的目录mkdir -p /u01/app/oracle/oradata/oradu/[oracle@localhost ~]$ export ORACLE_SID=oradu[oracle@localhost ~]$ sqlplus / as sysdbaSQL*Plus: Release 11.2.0.3.0 Production on Sun Mar 20 12:56:36 2016Copyright （c） 1982, 2011, Oracle.
