There's a new tool available to help automate the process of configuring CF Admin datasources to be monitored (wrapped) by FusionReactor. What used to be a multi-step manual process is now just a single button.
Check out the JDBC Wrapper Tool. For now it's technically a "community contributed" tool (not in labs, and not from Intergral as a formal product). But it was written by an Intergral employee, Dave Stockton, and the company is very interested in your feedback about it. (Intergral is the company behind FusionReactor and FusionDebug.)
Check out the page for the download, docs, screenshots, a change log, tested databases and CFML server configirations, and more. (And note that it's not just for CF, but is intended to work with others. Railo support is listed coming soon **that's an update from the original post, where I said Railo support was there**.) If you can try it on other DBMSs and CFML servers, they'd welcome that input.
For those who have needed to monitor/wrap datasources, especially many, or on many servers, this is a real gem. Whether you are or not using a supported server, it's worth a few minutes of your time to check things out. I've used it, and it worked great.
For those not sure what this datasource monitoring/wrapping is all about, check out an entry I wrote earlier this year, What is the FusionReactor datasource monitoring feature? Why would I use it? Powerful stuff!. Both that and the docs I link to will give you more info. The datasource monitoring really is really a great tool for troubleshooting and trend analysis.

It's a busy one, with 2 official Max talks, 2 Unconference talks, 2 Unconference panels, among other things. Here are the times and details.
Two Official Max talks:
Two Unconference talks:
Two Unconference Panels
I also may be giving a talk to an internal Universal Mind mini-conference going on the Saturday before the conference, held for all UM consultants (employees and contractors, like myself. I occasionally do consulting for them.)
So busy week, and that's before attending any sessions, BOFs, and so on! See you there. :-)

If you try to open the CF8 server monitor and get the error "ColdFusion Server is unavailable", the problem may be in your web server configuration. In this entry, I help you confirm if you're getting the problem I refer to here, and of course I show the solution (3 actually), with a caveat.

Someone asked for help on one of the Adobe forums, with a problem about users reporting that the server was not responding for extended periods.
After checking the logs (CF, Windows event, and IIS logs) and not "seeing anything to indicate errors", he wondered if somehow "you can set site availability windows".
I replied to him that, no, there are no features to set "windows of availability" for CF. So either CF was up and responding, or it wasn't. Even if it was, it may also be that his problem was with IIS. There are a few things that he could check....

Someone noted that an old entry that had been entered previously in my UGTV repository now broke. I looked into it, found the answer, and am sharing it here for others.
It's understandable, since Breeze was renamed to Connect a long time ago, but the bummer is that so many folks have for so long pointed to such recordings, and now they will all break. I've changed all the UGTV entries.
Here is a table of the old URLS and new ones that I've found to work for each. It's not always quite as obvious as it may seem:
| Old URL | New URL |
|---|---|
| These need adobe.acrobat.com | |
| adobechats.adobe.breezecentral.com | adobechats.adobe.acrobat.com |
| adobechats.breezecentral.com | adobechats.adobe.acrobat.com |
| mmchats.breezecentral.com | mmchats.adobe.acrobat.com |
| mmusergroup.breezecentral.com | mmusergroup.adobe.acrobat.com |
| seminars.breezecentral.com | seminars.adobe.acrobat.com |
| These just need acrobat.com | |
| experts.breezecentral.com | experts.acrobat.com |
| stevenerat.breezecentral.com | stevenerat.acrobat.com |
| mmse.breezecentral.com | mmse.acrobat.com |
Of course, I'm sure there are many other URLS out there using breezecentral.com. I'm only listing those that were in my UGTV database, that I tested and changed.
So for example, Doug Smith had noted that this entry from a 2006 talk by Sean Corfield, on "Objects and Persistence" failed (with domain not found):
http://adobechats.adobe.breezecentral.com/p31075720/
The correct new URL is:
http://adobechats.adobe.acrobat.com/p31075720/
So I've taken care of the UGTV entries. If you have your own listing of such URLs, I hope you'll take note of all this and make the changes for yourself and your readers.

Sadly, many (sometimes most) of the entries in the logs are innocuous (you don't need to worry about them), but sometimes they're useful. And if have noticed the logs, perhaps you'd like to know more about them.
There's a useful MS document, Error logging in HTTP API, with more about the HTTPERR logs, including their location, format, and info on the kinds of errors reported within them. Hope that's helpful to my readers.
Here's another (more brief) introduction to the files: in the technical reference section of the IIS 6 docs.

Of course, we take it as a given that this could happen in many places today, but what's interesting is this isn't an account from today, or yesteryear. Not 100 years ago, nor even 1,000 years ago, but the late 4th century AD!
Here's what he had to say (and how we can relate):

Instead, it's at 2pm.
I've updated that entry, but those who get the feed of this blog won't get notified of that update, I've decided to do this new entry.
"Intermediate ColdSpring: Remote CFCs", with Tom Chiverton
Thursday, Oct 16, SPECIAL TIME 2:00pm US EDT (GMT-4)
The unusual time in the early afternoon (in US Eastern time) is because our presenter is in London, where it will be his 6pm.
Of course, the first talk (at noon, with Isaac Dealey) is on at its scheduled time. More info in the notice last week.

Some of these offer knowledge and understanding, others offer specific steps to follow. Most offer links to still other resources (including often specific entries in Books Online).
Note that some may be written more to those still running SQL Server 7 (less likely) or SQL Server 2000 (not so unlikely), though many do cover SQL Server 2005 as well. Just keep this in mind while reading, both if some step doesn't seem to follow, and also in case it may be that some setting that suits one release may not suit another. In fact, some of the resources specifically discuss how things have changed in later releases, and how in fact some settings or techniques for older releases may be very different for later ones. All this just calls for discernment while you read.
These are all in addition to a couple of entries I wrote back in April (starting here) on some other advanced tools and techniques for diagnosing SQL Server problems.
Sometimes CF gets blamed for problems when in fact the problem is in the DBMS--and it's not always a problem due to the SQL being sent from CF. Sometimes the same code can run very differently one time than another. In that case, you really need to understand why this is happening. I hope the resources above may help you. If you ever want direct assistance, this is one of the things I help people with in my available consulting.
