通过RMAN克隆11g数据库（基于active database）
11g的RMAN duplicate 可以通过Active databaseduplicate和Backup-based duplicate两种方法实现。这里的测试使用的是Active databaseduplicate，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。
监听，口令文件配置，pfile配置，创建clone库相关目录等过程同基于备份的RMAN复制一样
