I have been doing a number of installations of SAS 9.2 eBI / eDI over the last week, to get a bit of practice in.

When I did installs on VM instances everything worked fine.

But when I did the install on a native machine, none of the Web Apps (SAS Portal, Web Report Studio etc) would  deploy and I would just get an error when trying to access the url via a browser (i.e /SASPortal/).

Eventually I tracked it down to an issue with the IPv6 setting.

So I changed the setting in the wrapper.conf file under:

<sas-config-dir>/Lev1/Web/Applications/RemoteServices/

And changed the line:

wrapper.java.additional.6=-Djava.net.preferIPv4Stack=true -Djava.net.preferIPv6Addresses=false -Dmulticast_udp_ip_ttl=0

to become

wrapper.java.additional.6=-Djava.net.preferIPv4Stack=false -Djava.net.preferIPv6Addresses=true -Dmulticast_udp_ip_ttl=0

So effectively switching from IPv4 to IPv6.  Reboot the server and we are away.

No idea what IPv6 does so need to do some research.

There is some more detail on IPv4 vs IPv6 and SAS 9.2 in this tech support note:
