1 参数文件中的 db_name为修改
oracle@yangDB1:/home/oracle>export ORACLE_SID=orcl

connected to target database: ORCL (DBID=1286259285)
RMAN> connect auxiliary sys/yang@yqldb
connected to auxiliary database: ORCL (not mounted)
RMAN> 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：
oracle@yangDB1:/home/oracle>export ORACLE_SID=orcl
oracle@yangDB1:/home/oracle>rman target /
