              (SID_NAME = orcl)
                  (ORACLE_HOME = $ORACLE_NAME)

                   (ORACLE_HOME = $ORACLE_NAME)   #查看  echo $ORACLE_NAME
                   (SID_NAME = ORCL)  #查看 echo $ORACLE_SID
              )

cd   $ORACLE_HOME/network/admin/listener.ora,添加

orcl =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = ip地址)(PORT = 1521))

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME =db)    #查看SERVICE_NAME ：   sqlplu / as sysdba    

                                               #SQL>   show parameter service
