一天主机上有多个数据库，导致其中一个数据库的监听无法启动

今天看了飞总的一个博客，针对一台主机上有多个版本的数据库，导致其中一个数据库无法启动，监听不兼容，虽然一个9i的数据使用的是1522,10g的数据库的端口使用的1521，但是
数据监听不兼容ipc冲突，需要注释了一个

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

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /u01/oracle/9 .2.0 /db_1 )
      (PROGRAM = extproc)
    )
    (SID_DESC =
      (GLOBAL_DBNAME = xifenfei)
      (ORACLE_HOME = /u01/oracle/9 .2.0 /db_1 )
      (SID_NAME = xff)
    )
  )
