Hi All,

I'm in the process of clustering 2 machines running W2K
Advanced Server that have IBM HTTP Server installed and
running.

My question is - Will the IBM HTTP Server running on the
secondary act as the fail safe support for the one running
on the primary?

If anyone has tried this before, please reply asap.

thanks in anticipation,
Vinayak
 
Hi,

I have an active passive cluster, as we speak for IIS. I would recomend to
implement this solution. Actually we are going to get rid of this strategy
an only use it for our SQL server databases. It is not the best strategy for
IIS. I would recomend Windows Network Load Balance for this. Both of you
servers will serve web pages, and if one fails, the other one will take the
load.

To answer your question about failover... yes a second node in an active
passive cluster will take over and own the cluster. If you are nated, you
will need to update your arp cash once the failover is completed. If you do
not, your websites arp entries in your gateway, may not be acurate. I have
not found a was to updated the arp cash automatically. Each time a failover
occurs, I have to refresh the arp cash manually.

For the IBM HTTP Server, if your question is related to a specific IBM
product, I do not know the answer.

To update your arp cash, simply create a generic resource that will
run a small script/batch file updating the arp cash. Have the resource
dependant on the web services. Every time they fail and come back
online the batch/script will run updating the arp cash.

NLB is a better solution for the fault tolerant IIS but its still the
same basic principles.
