环境：
操作系统：win 7 x64
BIEE版本： 11.1.1.7
RCU数据库：Oracle 11.2.0.1
现象：
BIEE启动正常运行一段时间后，出现无法登录analytics应用的情况。
重启BIEE之后，analytics可用，但运行一段时间后再次出现无法登录的错误。
此现象周期性发生。
检查domain日志，发现如下错误信息：

检查日志发现，运行一段时间后，发生登录认证错误，错误为Root exception is java.net.ConnectException: Connection timed out: connect，因为无法链接到2001:0:9d38:90d7:4d9:e8cb:21d1:eb2c:7001（如日志中红色斜体加粗部分），无法连接LDAP来为内部用户bisystemuser获取认证，因此也就无法获得正在登录的用户（如weblogic）的认证凭证。
错误的根本原因在于2001:0:9d38:90d7:4d9:e8cb:21d1:eb2c无法连接，由字符串可知其为ipv6的地址。
通过ipconfig /all命令，发现
此地址被设为了首选地址，而ping此2001:0:9d38:90d7:4d9:e8cb:21d1:eb2c地址时，可发现2001:0:9d38:90d7:4d9:e8cb:21d1:eb2c无法连接，一直返回超时错误。
解决方法：
解决方法有两种：
1.简单的在Windows下禁用IPV6 的方法。 使weblogic启动时选择ipv4地址，可避免BIEE此故障再次出现。
禁用方法：
首先把网络链接属性里面的IPV6去掉，如下图
然后以管理员身份打开CMD 运行以下命令 手动关闭IPV6的隧道()
netsh interface teredo set state disable
netsh interface 6to4 set state disabled
netsh interface isatap set state disabled
这样就可以把IPV6禁用掉。
再运行一下 ipconfig /all
可以看到IPV6 的地址和IPV6--IPV4的隧道不再出现。
如果想还原再运行下面命令就可以了
netsh interface teredo set state default
netsh interface 6to4 set state default
netsh interface isatap set state default
2.手动修改weblogic的启动选项，添加-Djava.net.preferIPv4Stack=true属性。
需要修改的文件位于base_domain的bin目录下的startweblogic.cmd，在此文件中
找到call "%DOMAIN_HOME%\bin\setDomainEnv.cmd" %*
再下面添加一行
set JAVA_OPTIONS="%JAVA_OPTIONS% -Djava.net.preferIPv4Stack=true"
保存此文件，重启BIEE即可。
