Not significantly. They both depend on a library that gets plugged in to the server, they both bootstrap etc. > For what we have been experiencing (IIS [separate server] | CF702/JRun 4 > updater 7 [2 servers, 2 instances each]; recently JVM1.5), > it seems to me that there is too much dependence between IIS and individual > CF instances. > - at times, if one instance does off line, the whole site goes down. > - if an instance is off-line when IIS comes up, it is not added to the > cluster when it comes back on-line I have experienced both issues quite frequently. Luckily so far this behavior is pretty consistent and detectable befor you bring systems online. Once you have a working setup it keeps working. > - IIS needs to be restarted if there is a change in the cluster For some changes that is correct. For instance, if you switch on sticky sessions the connector library in the webserver needs to re-initialize so it knows it has to start paying attention to the jsessionid. For that you need to restart the webserver. > Has any one noticed any improvements in clustering in CF8? > > Updater 7 for JRun was meant to have clustering fixes, but we have not > noticed it :-( I have noticed differences between a JRun installed with the CF 7.02 installer + JRun Updater 7 + CF 8.01 EAR files + JDK 1.6U5 versus a clean CF 8.01 install with the same CF 8.01 EAR files. In my setup (and I do some tricky things to get EAR file autodeployment working) I see more errors in the upgraded setup as in the clean setup.
