【RMAN】使用RMAN duplicate复制同机数据库遇到的问题

<b>1 参数文件中的 db_name为修改</b>

connected to target database: orcl (dbid=1286259285)

rman&gt; connect auxiliary sys/yang@yqldb

connected to auxiliary database: orcl (not mounted)

rman&gt; exit                                         

原因：实例名称和yqldb不符，修改inityqldb.ora文件中的db_name=‘yqldb’

修改后正常：

connected to auxiliary database: yqldb (not mounted)

<b>2 监听方面的问题：</b>

   linux error: 111: connection refused

修改 (global_name = plsextproc)为 (global_name = yqldb)
