CF2016: What's deprecated and/or 'no longer supported' (note: nothing 'removed')

Note: This blog post is from 2016. Some content may be outdated--though not necessarily.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.
Continuing a series of posts I started last week on ColdFusion (2016 Release), aka CF 2016, I'd like to highlight the items that Adobe has chosen to deprecate and/or declare as "no longer supported", as of CF 2016.

Stuck running the ColdFusion 'Migration wizard'? Here's how to get past that

CF Admin migration wizard screenSomeone presented a problem on a discussion list where they found that upon installing CF, they got to the "migration wizard" screen, and though it offered the option to "continue" if it hung up, it did not continue for him.

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. :-)

Great set of substantial, practical, but brief videos on IIS

Note: This blog post is from 2016. Some content may be outdated--though not necessarily.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 isn't "new" information, though it was new to me this week. I came across this excellent set of youtube videos, 50 substantial yet brief overviews of key IIS topics from IIS/.NET/Windows guru Scott Forsyth.

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).

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.

Solving slow CF startup: my elaborating on an Adobe blog entry on a possible solution

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.
The fine folks at the Adobe CF blog posted a blog entry today, on "Sometimes ColdFusion services refuse to start normally post server restart" (by Rahul Upadhyay), which offers some helpful information on one possible solution to the stated problem of slow CF startup.

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 cloud: 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.

CF911: 'Help! I've updated the JVM which ColdFusion uses, and now it won't start!'

Note: This blog post is from 2014. 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.
Has this happened to you? You wanted to update the JVM which CF uses to use a new version...
  • so you found some resource on the web showing how to update, and it seemed simple enough
  • and then you tried restarting CF and wham, it won't start, or the admin won't open, or code starts failing
  • and maybe it's that things didn't fail immediately, but within hours or days folks report things breaking since you made the change
  • and now you're stuck wondering, "what happened? and how am I supposed to fix this?"

It's a tough position to be in, and tragic of course if CF won't start. But no, you do NOT need to reinstall CF!

Often it's just one thing you did by mistake, though there are indeed several possible reasons why your attempt to update CF's JVM can fail or lead to unexpected problems. And as you google about, you may find all kinds of helpful but often misinformed or spartan suggestions that may or may not help much.

So I offer here over a dozen of things you can and should consider/look at, some of which you may quickly recover from or be able to undo (depends on what you did). And all this applies to Lucee, Railo, and BlueDragon as well, though folder locations will differ.

If you're facing this bind right now, you can skip over the following to the the section, "So what went wrong?", where I present each likely problem and solution.

My reply to: 'The price for CF troubleshooting consultants is a joke. They're taking us for a ride'

Note: This blog post is from 2014. 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.
Ok, so that's clearly not my sentiment but rather that of a certain "Simon" (no other identifying info offered) in a blog comment in one of the recent CF team blog entries.

After complaining about how poorly he felt CF had responded to his seeking help, he threw in additionally that "the existing private consultants prices are a total joke - they are taking us for a ride!".

Well, I just couldn't let go his comment go unremarked.

I started to write my reply there, but it grew long (as is my wont). So rather than post there (where most comments are brief), I decided to post it here instead and point to it there. Perhaps some of my readers here may appreciate it as well, as I also talk about some thoughts on CF troubleshooting in general.

Hidden Gem: Importing CF Admin settings in ANY release via 'import wizard', even AFTER installation

Note: This blog post is from 2014. 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.
Have you ever faced the challenge of needing to migrate the CF Admin settings (datasources, mappings, scheduled tasks, etc.) from one machine to another, and from one CF version to a newer one? Did you know that there is an "import wizard" that you can (with proper configuration) run at any time to import settings from one release to another?

Before I discuss that, you may know of a couple of other solutions for this challenge: the CF admin ColdFusion Archive/CAR mechanism, available in some but not all editions (more below), and this same "import wizard" which runs at the end of CF installation, importing settings from an older CF version if found on the same box.

But what if either of those solutions don't work for you, and you have dozens of dsn's, scheduled tasks, mappings, or other settings you want to get from one machine/version to another?

You are NOT stuck having to manually copy settings from one screen to another! (And you should be very careful about the common hack solution of copying neo*.xml files from one instance to another, which may not always work and may break things.)

In this entry I'll discuss how you CAN indeed import the CF admin settings from nearly ANY release of CF into nearly ANY OTHER release of CF, in a fully supported way, and which CAN be done even after installation of a new CF release. (I say "nearly", because I worked with someone wanting to do this import of CF7 settings into CF10, and that large a jump was was not supported.)

I'll also mention an important potential gotcha to beware, as well as how to to get around that.

Hidden Gem in ColdFusion 11: ColdFusion Archive (CAR) support now in Standard

Note: This blog post is from 2014. 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.
Here's a nice surprise for some about a change in CF11: you can now create and read CAR files (ColdFusion archive files, a CF Admin feature) in the STANDARD edition of ColdFusion 11. In prior releases, it was available only in ColdFusion Enterprise.

Read on for more, including a gotcha regarding importing from previous release Standard editions, but for many this news will be a delight and all they need to know.

For more on what the CAR mechanism is, finding more on it, the gotcha (and what NOT to do if you hit that gotcha), and info on still more hidden gems in CF, read on.

Find ColdFusion installers, updaters, hotfixes, and docs for all recent releases at CFMLRepo.com

Note: This blog post is from 2014. 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 won't be new info for some, but many folks remain confused by the fact, that after Adobe released ColdFusion 11 2018, they can seem to only find ColdFusion 11 2018 installers on the Adobe site. What if you need installers for 2016, 11, 10, or 9, or 8, and so on?

(Update: I wrote this post originally after CF11 came out, but it applies as well and still now that CF2018 has come out, so I have changed the references to that from here on.)

Find CF installers, updaters, and docs for past several releases

The good news is that if one wants to find ANY installers for most ANY version of CF, they can be found on an external repository setup by Gavin Pickin (and added to by myself and others, to include updates, hotfixes, and docs):

Gavin Pickin's CFML Repo

The name, CFMLRepo, may confuse some if they presume it's a repo of CFML. It's not. What it is is that originally it did originally have only CF installers (and updates, etc.) but then some contributed installers for Lucee and such, so he chose the more "generic" name.

(There used to be a longer and hard-to-remember URL, when I posted this originally in 2014, and I had created a shortened url, http://bit.ly/cfdownloads. It's now not "shorter", so I leave this here for posterity.)

Thanks so much to Gavin for creating the repo, and to him and others for maintaining it. Let's hope it remains a viable solution to find downloads for years to come.
