求助：linux AS3 Oracle10g LISTENER启动出错问题

jrill

oracle 能正常启动关闭，但LISTENER启动不了，出错如下：
TNSLSNR for Linux: Version 10.1.0.3.0 -Production
......
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC)))
TNS-12547: TNS:lost contact
  TNS-12560: TNS:protocol adapter error
    TNS-00517:Lost contact
     Linux Error: 104: Connection reset by peer
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=mytst)(PORT=1521)))
TNS-12541: TNS:no listener
  TNS-00511: No listener
    Linux Error: 111: Connection refused

listener.ora为：
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /home/oracle/product/10103)
      (PROGRAM = extproc)
    )
)
LISTENER =
(DESCRIPTION_LIST=
   (DESCRIPTION =
     (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
      )
      (ADDRESS_LIST =
       (ADDRESS = (PROTOCOL = TCP)(HOST = mytst)(PORT = 1521))
       )
     )
  )

tnsnames.ora为：
ORA10G =
   (DESCRIPTION =
     (ADDRESS = (PROTOCOL = TCP)(HOST = mytst)(PORT = 1521))
     (CONNECT_DATA =
       (SERVER = DEDICATED)
       (SERVICE_NAME = ora10g)
     )
    )
EXTPROC_CONNECTION_DATA =
   (DESCRIPTION =
     (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
      )
      (CONNECT_DATA =
       (SID = PLSExtProc)
       (PRESENTATION =RO)
     )
   )

jrill

经过查看trace日志，发现有如下报错信息：
Attempted load of command line source
Parameter source was not load
.......
No process parameters set
........
查看过参数的相关要求配置，估计与地址配置有关，后想到修改linux地址
及主机名时系统自动去掉了默认的地址及别名，试着加上原有别名localhost，再启动lsnrctl start LISTENER，一切OK!真是不可释疑。
