2. 测试一下 c$ share 是否成功. 方法是在cmd里打net use \\localhost\c$ 失败会是这样子...: 系统错误53
The network path was not found. 成功是这样子: 命令成功完成。
3. 如果第2步失败, 检查"服务"里的"TCP/IP NetBIOS Helper"服务是否已开启, 没有的话启动它即可. 解决系统错误53的经过：
使用命令net usenet use \\localhost\c$时，发生错误53，找不到网络路径。我在虚拟机中输入：net share命令，发现只有一个IPC$（原来默认共享被关闭了），经过一翻百度后，找到了解决办法：第一步：检查AutoShareServer和AutoShareWks注册表值，以确保未将它们设置为0。依次点击“开始→运行”，输入regedit，然后按回车键进入注册表编辑器。
第二步：找到并单击HKEY_LOCAL_MACHINESystemCurrent ControlSetServicesLanmanServerParameters。 第三步：如果LanmanServerParameter
s子项中的AutoShareServer 和AutoShareWks DWORD值配置的数值为0，则将该值更改为1
打字不易，如满意，望采纳。
前提回现修改了主机名，由hyldb修改为hyl。
问题现象
配置监听，警告提示，如下所示：
解决方法
1、检查1521端口
[root@hyl ~]# netstat -a
--查看端口占用情况，查明1521端口并未被占用

2、检查hosts
[root@hyl ~]# vi /etc/hosts
修改前：
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 hyldb localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
192.168.56.101 hyl
~
~
~
--由于修改了主机名（hyldb修改为hyl），将之前配置中hyldb内容删除
修改为：
# 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
192.168.56.101 hyl
~
~
~
~
3、检查network
# vi /etc/sysconfig/network
--确认添加了如下信息
NETWORKING=yes
HOSTNAME=hyl
4、检查ipv6是否关闭
查看ipv6状态，查看其是否被关闭
[root@hyl ~]# lsmod |grep ipv6
ipv6 435105 17 cnic
xfrm_nalgo 43333 1 ipv6
[plain] view plain copy 在CODE上查看代码片派生到我的代码片
补充：关闭ipv6方法
1） # vim /etc/modprobe.conf
在其中加入下面这一行，
install ipv6 /bin/true
保存并退出。
2）# vim /etc/sysconfig/network
在其中加入下面配置项：
NETWORKING_IPV6=no
IPV6INIT=no
重启后查询：
[root@hyl ~]# lsmod |grep ipv6
--没有显示ipv6相关信息，表示ipv6已经关闭
5、重启系统后，查看hostname
[root@hyl ~]# hostname
--查询主机名
hyl
6、再次执行netca
配置监听、dbca建库成功。
通过配置本地数据库的tns配置文件实现：去oracle安装目录下oracle\product\10.2.0\db_2\NETWORK\ADMIN\ 找到tnsnames.ora，用记事本打开，里边有远程数据库的tns连接配置串如下
ORCL23 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.3.23)(PORT = 1521))
)
(CONNECT_DATA =
(SID = ORCL)
)
)
添加好ip、端口和目标数据库的实例名(SID)，然后确保tns名称(ORCL23)在整个文档中唯一，保存后打开数据库连接工具，输入远程数据库上的用户名密码，选择数据库对象为你配置的连接名就可以了
