Question

当然要配置监听服务了，我这边有个例子scounix5.0.4+oracle7.3.4
编辑 etc/listener.oraLISTENER =
  (ADDRESS_LIST =
        (ADDRESS= (PROTOCOL= TCP)(Host= ip)(Port= 1521))
  )
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME= dbname)
      (ORACLE_HOME= /usr/oracle)
      (SID_NAME = sidname)
    )
  )
STARTUP_WAIT_TIME_LISTENER = 0
CONNECT_TIMEOUT_LISTENER = 10
TRACE_LEVEL_LISTENER = OFF在用oracle用户运行：lsnrctl start
