I am having a problem with Data Director for Web. I have a server that
is in the DMZ and am trying to talk to it from within the internal
network. I can connect to it using the DMZ ip address using Ilogin and
can use dbaccess with no problem. When I try to use DDW's sitemanger
to make changes to the web pages, the sitemanager will lock up. The
sitemanager will display the databases then the projects under the
databases. When I try to display the webpages under these projects,
sitemanager will lock and it will cause a "Checkpoint Required" which
never goes away. I have to then bring Informix down and back up to
clear the problem. When I move the server from the DMZ to the internal
network, this condition goes away but this will not work as the outside
world would not be able to access the system.

By the way, this system receives data from another Informix system
inside the internal network. This portion works well.

I am using Redhat Linux 8 with DDW 2.00.TC5 and Linux IDS 9.40.UC5.
Also the Apache webserver.

Any help would be greatly appreciated.

Which version of Apache and which version of the WebBlade. If you
don't have a default INFORMIXSERVER set then DDW can mis-behave, but
iLogin/DBPing are fine. The later versions of DDW also do a full
screen, i.e. data, refresh when navigating around screens, this can
cause sitemanager to appear to hang. It is especially bad over a slow
connection.

Cheers
Paul

Paul,

I am using Apache 1.3.31 and Datablade web.4.12.UC1. I tried using
web.4.13.UCx but I got the same result so I decided to try an earlier
version.

Harry,

Paul,

I am using web.4.12.UC1 and Apache 1.3.31. I was using web.4.13.UCx
but when I was having the same problem, I decided to revert back to see
if it would help. It did not.

Thanks,
Harry

Harry

what you are trying to do and the versions should be fine, and we run
our internal systems as you describe. Stick with 4.13 it's a better
version with some added predefined functions, although some only appear
to be in the FC version.

One of our remote system has a similar problem to yours, I could telnet,
ssh etc to the server but I couldn't connect to the DB. It turned out
to be a firewall problem and was solved by addding static route

Cheers
Paul

Paul,

I have discovered the problem. It is a DNS resolver problem. When you
take the DNS out of the resolv.conf so that it has to use the
/etc/hosts, DDW will work. It will bring up the web pages and will
allow all functions. As soon as you place it back in so it will use a
DNS, it will stop working.

When not working, it will allow you to select the server, then the
database, then the project and then the (image, text, dynamic tags).
Once you try to select any one such as "text", it will lock up.

We have tested this several times and it acts the same way every time
so this is definately the problem. I can get around the problem but
Informix needs to know about this so they can address it. Who do you
think would be the best person to send this to?

Harry,

Try changing your nsswitch.conf to use hosts first. All our prod
servers use files dns, our webblade installs have every similar versions
to yours and I've not seen this problem
