CF911: Help, How do I connect sites to a new instance w/ the ColdFusion 10/11 webserver config tool?

Note: This blog post is from 2015. Some content may be outdated--though not necessarily. Same with links and subsequent comments from myself or others. Corrections are welcome, in the comments. And I may revise the content as necessary.
This one causes a lot of heartburn for folks: you add a new instance in CF10 or 11 (in editions other than Standard, which do support adding instances), and you find that you can't seem to have the web server configuration tool (wsconfig) connect sites to that new instance(s). You never see the new instance listed in the UI of the wsconfig tool. What gives?

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.

Updates, updates. Get your CF updates! The CF Team has been busy fixin' bugs!

If you'd not noticed, the CF team has been busy fixin' bugs! Over 300 in CF11 in just the past month. Check out these two announcements today of prereleases of update 5 for CF11 and update 16 for CF10:

This is on top of the release earlier this week of the final version of CF11 Update 4 (which had been in prerelease for a couple of weeks):

Great to see the CF team cranking on the bug fixes. I count just under 120 in the technotes for CF11 update 5, and just under 40 in CF10 update 16. And there were just under 200 fixes in Update 3 of CF11, which again was released just in recent weeks.

Yeah, but what about all those bugs?

Yes, I know some could twist things and say "yeah, but the problem is that there are so many bugs to be fixed". Sure.

Still, for others who may have longed to see their bugs fixed,

Free, simple code to find out what SQL statements are running slow in SQL Server right now

Often when people are trying to troubleshoot seeming problems in ColdFusion (or whatever app server you may use), they may wonder if (or have tools which suggest that) their CF requests are being held up waiting for a query to run in the database, which seems hung up.

Wouldn't it be nice to know, at any moment (such as when things are going badly), just what queries (or stored procedures or commands) were running in the database at that point in time?

Well here's good news: if you're running SQL Server, the following SQL query will show you just that: the currently running SQL statement(s) and some additional details about each query including their duration, their database name, the program executing the SQL, the session id, and much more.

For more (including why things like Activity Monitor, sp_who2, and others aren't the answer, as well as what to do if you may be unable to run this code), please read on.

Understanding SQL Server Statistics: A great, free, relatively brief ebook

Note: This blog post is from 2015. Some content may be outdated--though not necessarily. Same with links and subsequent comments from myself or others. Corrections are welcome, in the comments. And I may revise the content as necessary.
If you want to understand the important concept of SQL Server statistics (a mechanism within SQL Server which tracks metadata about your data, and which can significantly affect query performance if not managed well), I think you can do no better than than to spend an hour or so reading the free 40-page e-book, SQL Server Statistics, written by Holger Schmeling and offered by Red-gate. book cover

The book is a quick read, and really well done, including a discussion of what statistics are, why they're important, how to diagnose trouble with them, and how to use the SSMS interface and/or SQL statements/commands to better understand them.

There are plenty of screenshots and it's written in a tutorial manner. And while it's from 2010 and covers only up to SQL Server 2008, most of the concepts apply just as well to SS 2012 and beyond, and of course many organizations are still running on SS 2008 or even earlier!

Most important, Schmeling explains why it's important that you take responsibility to both create and maintain statistics (rather than leave it as something that "the database" should handle. And if you are leaving it as something "the db should handle", you can use this to make sure that person is doing their job with respect to statistics.)
