今天打开监听程序时，报以下错误：
TNS-12560: TNS:protocol adapter error
  TNS-00507: Connection closed
        Linux Error: 29: Illegal seek
开始认为是Linux本身内部错误，检查hosts文件： 
[oracle@localhost ~]$ cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1               localhost.localdomain localhost
::1             localhost6.localdomain6 localhost6

没有什么问题。


检查listener.ora:
LISTENER =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521))
  )


SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =       
      (GLOBAL_DBNAME = jing)
      (ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
      (SID_NAME = orcl3939)
    )
    (SID_DESC =
      (GLOBAL_DBNAME = tai)
      (ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
      (SID_NAME = orcl3939)
    )
  )




SID_LIST_WEN =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
      (PROGRAM = extproc)
    )
  )
WEN =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1522))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
    )
  )

检查tnsnames.ora:

diy =
(DESCRIPTION =
    (ADDRESS_LIST =
        (ADDRESS=(PROTOCOL=TCP)(HOST = localhost.localdomain)(PORT = 1522))
    )
)

SQL> show parameter local_listener;


NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
local_listener                       string      DIY
SQL> show parameter service_names;


NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
service_names                        string      a,b,c,d,diy
SQL> show parameter instance_name;


NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
instance_name                        string      orcl3939

以上检查没有异样。
然后重启os后，竟然可以启动监听程序：
[oracle@localhost ~]$ lsnrctl start listener

以上原因不清楚是OS还是oracle造成的。网上有朋友遇到同样错误解决的方法 blog.chinaunix.net/uid-20048945-id-471098.html，尚不明白我重启后可以使用。
