Tomorrow (Friday) I will be presenting at CFUnited on Clustering and HA (High Availability) in ColdFusion.  This is at 2:00PM and I am working toward making this worthwhile, for those who are good enough to take the time to attend.  For most of today I have been trying to finish up my presentation using the Enterprise Manager in ColdFusion 8.01 Enterprise.  This has proved to be relatively fruitless and this has happened many times before.  This typically revolves around the Cluster not seeing one or other of the instances as running, even though they were re-started several times in Windows services (this is Windows 2003).  I have observed this many, many times on site with clients.  So what will I do about this as it pertains to my presentation?

Well, firstly I will be soldiering on to make it work, as I am currently.  Secondly, if I am unsuccessful I will move to creating a cluster via JRun-manually.  Lastly, we will at the very least have a very lively Q-A session and field any and all questions you may have.   The stark reality is that clustering is hard and unreliable to configure via CFAdmin but we will find a reliable work-around for this, as I believe clustering CF reliably, is an imperative.

I am commenting on my own blog post here, this is an update, a postmortem on my presentation. I eventually got clustering to work reliably it took three uninstalls and re-installs of CF Enterprise. These were very clean uninstalls I cleaned the registry fully and made sure all directories and files were removed between each try. Eventually on the third attempt the cluster members saw each other and I was able to do what I aimed to do, run a load test live against a real application whilst removing cluster members (shutting down servers). I hope the presentation was useful to those who attended.

Good to know that such kind of posts are there to help ignorant and novice people.
