今天用rman连接数据库报错[linuxidc@rhel55 ~]$rman target sys/Oracle@orcl ORA-12514: TNS:listener does not currently know

今天用rman连接数据库报错
[linuxidc@rhel55 ~]$rman target sys/Oracle@orcl

ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
[linuxidc@rhel55 ~]$lsnrctl stop

[linuxidc@rhel55 ~]$cd $ORACLE_HOME

[linuxidc@rhel55 db_1]$vim listener.ora

修改/u01/app/oracle/product/11.2.0/db_1/network/admin/listener.ora文件
加上
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = orcl)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)
)
)
然后重启lisener服务,就ok了[linuxidc@rhel55 db_1]cd[linuxidc@rhel55 ~]$lsnrctl start

[linuxidc@rhel55 ~]$
[linuxidc@rhel55 ~]$ rman target sys/oracle@orcl
