duplicate database的时候,rman连接 auxiliary database的后状态不正确

auxiliary database 已经被startup nomount,但是rman连接后显示状态是not started

$ export ORACLE_SID=dupdb

$ sqlplus '/as sysdba'

SQL> startup nomount 



$ rman

RMAN> connect  target sys/oracle@ora11



connected to target database: ORA11 (DBID=785451981)



RMAN>  connect auxiliary sys/oracle@dupdb



connected to auxiliary database: DUPDB (not started)

#not started,说明我们连接到一个空闲例程,这种情况通常就是静态服务名中ORACLE_HOME配置不正确,或者SID配置不正确导致的。
检查监听文件,发现oracle_home路径最后多了一个'/'

SID_LIST_ORA11 =

        (SID_LIST =

                (SID_DESC =

                        (GLOBAL_DBNAME = ora11)

                        (ORACLE_HOME = /u11/app/oracle/product/11.2.0/dbhome_1)

                (SID_NAME =ora11)

                )

                (SID_DESC =

                        (GLOBAL_DBNAME = dupdb)

                        (ORACLE_HOME = /u11/app/oracle/product/11.2.0/dbhome_1/)

                        (SID_NAME =dupdb)

                )

        )

把上面代码中的'/'去掉即可。

另外我们通过sqlplus xxx/xxx@xxx as sysdba的方式也可以测试一下是否连接到启动实例的实例,还是连接上了空闲实例。
