这样可以连接d:\>sqlplus scott/tiger@ora9i
报错：ora-12535：TNS：操作超时何因？？？？数据库是本地的数据库，数据库名和实例名都为：ora9itnsnames文件如下：
ora9i =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = hs-chy)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = ora9i)
)
)INST1_HTTP =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = hs-chy)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = SHARED)
(SERVICE_NAME = MODOSE)
(PRESENTATION = http://HRService)
)
)EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
)
)
sqlnet.ora文件如下：SQLNET.AUTHENTICATION_SERVICES= (NTS)NAMES.DIRECTORY_PATH= (TNSNAMES, ONAMES, HOSTNAME)
大侠指教，谢谢。
