sqlplus登录问题，
用system/orcl可以登录，用system/orcl@orcl就登录不了，就死在那里，没有任何提示.

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = d:\oracle\product\10.2.0\db_1)
(PROGRAM = extproc)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = hhs)(PORT = 1521))
)
)

不知道哪位高手可以解决一下，先谢了！
------解决方案--------------------
遇到过，没有通过修改参数等解决。
后来被迫无奈的重新安装了。
------解决方案--------------------
不用主机名用ip地址试试呢
------解决方案--------------------
C:\>lsnrctl status
C:\>lsnrctl stop
C:\>lsnrctl start
看看有什么异常么？还有就是看看Alert文件和trace文件，
里面记录了什么信息。
------解决方案--------------------
完全正常，看不出什么问题了
