If so, I have some very good news--and some not-so-good news. (Some may know that you can find this info also by running the CFC Explorer--more on that in a moment.) The unfortunate news is that it's not yet COMPLETELY documented, but it's still a good start.

In this post, I want to elaborate on one more common mistake. Well, mistake may be too strong word. It's about a default option when you run a Java JDK installer (see the other post for more on JDK vs JRE options).

In short, I make the case here for why you should NOT let the JDK installer implement its "public jre" option.

And you'll likely be in panic mode. Many find after applying a ColdFusion update that either CF won't start at all, or they can't access the ColdFusion Admin, or some part of CF or their app doesn't work. Or perhaps the problem may not become clear for hours or even days.

Typically the issue is that there was an error during the update process which CF attempts, and that might be rather easily confirmed and resolved. In this post, I share several tips and observations related to all this, based on my years of providing remote CF troubleshooting support.

You can find them listed as "whitepapers" at the bottom of ColdFusion.com (as I view it today, at least), so keep an eye there to see if perhaps any others may ever be added.

Here are the docs, with some observations also about their size and version, if available:

In this post, I'll share how to get past that prompt, if this happens to you. (And despite that image on the right showing ColdFusion 11, this could conceivably happen in CF10, CF9, and so on, and this same solution applies to all.)

For the anxious folks who want to "skip the waffle" and context/setup, the solution is at the very bottom. :-)

I offer the list of topic titles (and links to them) below, and have even created a YouTube playlist with them, but note that the links below go to pages that the author had created where he offered a helpful introduction to each video (more than appears in the Youtube description for each).

I had also wanted to offer here this brief overview of them, to set the context and encourage you to view them, so as not to dismiss them if other tech video series haven't impressed you. Whether you're new to IIS 7 or 8, or an old hat user, there really is something for everyone, including wonderful little tips he shares in passing during most videos (which average about 10-20 minutes each).

The solution is relatively easy, and the problem could maybe be fixed (or at least warned about) by Adobe (and I just filed a bug report for it). Until that happens, I wanted to share this. For more, read on.

That said, there are some concerns I have, with respect to how I fear some may read and take action based on it (especially the notion of deleting the cfclasses files, as a possible solution to the problem).

I'm not contradicting Rahul here, just elaborating on some points, as someone who (like some on the CF team) helps people with CF server troubleshooting every day.

I started to write these thoughts as a comment there, and (as often happens) it grew long so I thought it better to be a blog entry rather than a long comment, and point people here. Once I did that I decided to go further still, hoping to really help those interested to consider the issue more carefully. (It also gives me a chance to highlight again the Adobe CF team blog, something I recommend EVERYONE reading this should follow!)

One quick point (and update) for the TL;DR crowd: My recommendation is that you move the cfclasses folder out of that location, as a temporary test, to see if it makes CF startup happen faster. If it does, I explain why and what the implications are in the choices of renaming, deleting, moving, or disabling the related "save class files" feature. Also, I add an update in E.1 below (since posting this) which you may really want to read: consider turning off your anti-virus software's real-time protection against the cfclasses folder to see if that alone helps with startup.
