rman target / auxiliary sys/oracle@ standby ； RMAN-04006: error from auxiliary database: ORA-12528: TNS:listener: all appropriate instances are blocking new connections

备库LISTENER.ORA文件中全局服务名配错导致. 错误配置如下： SID_LIST_LISTENER=   (SID_LIST=      (SID_DESC=        (GLOBAL_DBNAME= primary .example.com)        (ORACLE_HOME=/u01/app/oracle/product/12.1.0/dbhome_1)        (SID_NAME=JDY)      )     (SID_DESC=        (GLOBAL_DBNAME= primary _DGMGRL.example.com)        (ORACLE_HOME=/u01/app/oracle/product/12.1.0/dbhome_1)        (SID_NAME= JDY )     )   ) 正确配置 SID_LIST_LISTENER=   (SID_LIST=      (SID_DESC=        (GLOBAL_DBNAME= standby . example.com)        (ORACLE_HOME=/u01/app/oracle/product/12.1.0/dbhome_1)        (SID_NAME= JDY )      )     (SID_DESC=        (GLOBAL_DBNAME= standby _DGMGRL.example.com)        (ORACLE_HOME=/u01/app/oracle/product/12.1.0/dbhome_1)        (SID_NAME= JDY )     )   )
