在一台机器上装了9.2.0.4和10.1.0.4数据库,启动监听时候发现有一个启动不了
9i监听配置

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST = xifenfei.com)(PORT = 1522))

      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
      )
    )
  )

  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = xifenfei)
      (ORACLE_HOME = /u01/oracle/9.2.0/db_1)
      (SID_NAME = xff)
    )
  )

10g监听配置

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /u02/app/oracle/db10g)
      (PROGRAM = extproc)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
      )
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST = xifenfei.com)(PORT = 1521))
      )
    )
  )

分别启动监听

这里很奇怪两个监听使用不同的端口,为什么不能提示Address被占用呢,难道9i的已经启动了

查看9i的监听状态

TNS-12618: TNS:versions are incompatible

9i监听不能启动原因
这里有重大发现TNS:versions are incompatible.我这台服务器只有一个9i和一个10g的数据库出现版本不兼容,那就是说这个命令可能访问了10g的库中的每个监听信息.继续往上看,发现(DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC))).
When a process is on the same machine as the server, use the IPC protocol for connectivity instead of TCP. Inner Process Communication on the same machine does not have the overhead of packet building and deciphering that TCP has.
通过这段话可以看出IPC(Inner Process Communication)是使用于本机的内部通讯,不用包的封装,可以很大程度上提高程序执行效率.看到上面的IPC提示,我们可以确定该错误是因为10g中已经启用了IPC,然后9i的监听也要来启动这个,从而导致该错误.

解决办法
因为在同一个机器上,只能其中的一个数据库启用IPC.修改9i的监听配置

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1522))
      )
    #  (ADDRESS_LIST =
    #    (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
    #  )
    )
  )

  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /u01/oracle/9.2.0/db_1)
      (PROGRAM = extproc)
    )
    (SID_DESC =

      (ORACLE_HOME = /u01/oracle/9.2.0/db_1)

    关于wndows 下用rman异机恢复后监听无法启动求指教.
    异机恢复好后用netca创建listeren监听一直启不来,ORACLE_HOME也设置过了.
