IPV6 is not supported or compatible either with Oracle Portal 10.1.4.2.0 or Oracle Application Server 10.1.3.4 because of the underlying Apache 1.3 which comes default with these 10g versions
which does not support IPv6.
For more information you could refer to the note:338011.1 "Does OAS 10.1.2 10.1.3 10.1.4 Support IPv6?"
Thanks you answered part of my question (I read that Apache 2.0 is compatible with IPv6)
Can you please mention about webcache too.. As WebCache is first interaction point for Internet User.
Any patches or Upgrade Recommended ??
Webcache also doesn't support IPV6.
So the workaround is to comment out IPV6 or disable the IPV6 .
