John, On page 19, bout half way down it states Load balancing between the clients and web servers without setting a sticky bit
If the web servers in your AR System were installed in a cluster (with fail-over enabled), then setting the sticky bit on the load balancer between the clients and web servers is not needed. This tells me directly that I can turn the sticky bit off on my web load balancer if I cluster my web server. Am I reading that wrong?....yes, I may need to add the distributable attribute to the mid-tier web.xml, but that shows as 'ok' to me based on the above statement from BMC, right? -----Original Message----- From: Action Request System discussion list(ARSList) [mailto:arslist@ARSLIST.ORG] On Behalf Of John Baker Sent: Friday, April 22, 2011 12:16 PM To: arslist@ARSLIST.ORG Subject: 7.6.04 - Load balancing Hello, I'm referring to the load balancing document and I think there may be some confusion. The document states the sticky bit isn't required for the LB between MIdtier and AR System server, but I can not see (and forgive me for not fully reading the document in detail) any reference to the LB in front of the Midtiers and the sticky bit. I therefore conclude that the LB in front of the Midtiers needs the sticky bit set because the Midtiers do not cluster. Further to that, the Midtier web.xml file doesn't contain: <distributable /> Which as you can see in this page: http://tomcat.apache.org/tomcat-6.0-doc/cluster-howto.html (Under clustering basics) needs to be included for Tomcat (and other servlet engines) to distribute sessions.
