HA with Zope

Hello Pound Users!

(I am a Pound Newbie)


This is my pound.cfg

ListenHTTP 192.168.10.171,80
ExtendedHTTP 1
WebDAV 1
LogLevel 2
Alive 3
#HIGH-AVAILABILITY 5

          UrlGroup ".*"
          BackEnd 192.168.10.206,8080,1
          BackEnd 192.168.10.211,8080,1
          EndGroup

Is this a HA and LoadBalancing Solution? What happens if one BackEnd is down?
I see nothing in LogFiles that onw BackEnd is down!

Thx in advance

christian

Hi

Yes it is an HA solution - the requests are distributed between the two 
back-end servers. To convince yourself try putting some load on Pound and 
immediately disconnect one of the back-ends from the network (or stop the 
server) - the following requests will be sent to the remaining back-end 
without an error. Reconnect the cable and you'll start seeing requests coming 
to it.

BTW, your Alive is a bit short (it's OK, but it will eat quite a bit of 
bandwidth; try a value of 10 for something more reasonable). You could also 
try LogLevel 3 (or 4) for more information.

Hope this helps some.[...]
