ORACLE的连接问题

[konma]

刚安装好QRACLE，一直都无法连接。监听不成功。附上两个参数文件内容，求高手帮忙

这里，HOST不是localhost吗？mydba1是什么？
SERVICE_NAME这里，是mydba吗？

mydba1是计算机名字吧
将 mydba1 换成 IP

这是我的配置文件，你对着比对下：

# SQLNET.ORA Network Configuration File: C:\oracle\ora92\network\admin\sqlnet.ora
# Generated by Oracle configuration tools.

SQLNET.AUTHENTICATION_SERVICES= (NTS)

NAMES.DIRECTORY_PATH= (TNSNAMES, ONAMES, HOSTNAME)

# TNSNAMES.ORA Network Configuration File: C:\oracle\ora92\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.

INST1_HTTP =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = www-9921c3c9704)(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)
)
)

OYPDB =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = www-9921c3c9704)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = oypDB)
)
)

1.删除监听器
2.删除连接服务
3.新建监听
4.新建服务

祝你好运！
