I am running Mapserver 4.6 CGI on Windows/IIS and attempting to make it work
in a twoserver cluster. I have all the shape files, map files, template
files etc duplicated on both servers.
When I attempt to generate a map it appears that the template is generated
on one server but the image may be generated in the /tmp directory of the
other server, causing no image to appear on the HTML page. If I look into
the /tmp directory of both servers I will find the missing image on one of
them and can double click and display it just fine. If I refresh the HTML
page enough times they will sync and the image will appear.
Obviously this is a problem. Can anyone running a cluster help me with
this?
Sure, I can try. I had the same issue when I first setup my web cluster.
Are you running a Linux Virtual Server? If so, you may need to consider
changing the scheduling algorithm. Currently, it sounds like you are
using a round robin, where each HTTP request is rotated between real
servers. You will need to change it to use a scheduler which schedules
requests from clients to the same real server during the session for each
client.
I have been running such a setup with mapserver without any reported
errors like the above.
