CFMeetup: Updating the Java underlying ColdFusion (View video , Show Description )With Java updates happening about quarterly (and one just last week), it's important that ColdFusion administrators and/or developers keep up to date on the Java version which underlies their CF (or Lucee) deployments. While the simplest question may seem to be "how do I do such an update, effectively" (and it really can be quite simple), there's a good bit more to updating the Java (aka jvm, jdk, jre) which underlies your CFML engine.
In this session, veteran troubleshooter Charlie Arehart will share his experience helping people deal with this topic for many years, including:
- Considering, planning the jvm update (what jvm do you have, what can you update to, why should you?)
- Performing the jvm update (where to get it, how to install it, how to configure CF to use it)
- Avoiding various potential gotchas when updating the JVM
- How to be made aware of new JVM versions
Whether you use CF or Lucee, deployed traditionally or via Commandbox (or even containers), most of the discussion will apply to you.

CF Summit 2021: Hidden gems in CF2021, a year later (View video , Show Description )It's been a year since the release of CF2021, and also since Charlie Arehart offered his “hidden gems” talk at last year's CF Summit. Perhaps you caught his talk then, or not, and maybe you've started using the release–or still have not. Either way, there've been a number of updates as well as some changes in features since the release. In this updated talk, Charlie helps both audiences consider aspects of CF2021 that they may have missed.

CFMeetup: Migrating apps to ColdFusion 2021 from earlier versions (View video , Show Description )While CF2021 has been out now for a year (released in Nov 2020), many orgs may only now be considering moving to it, whether from CF2018 or perhaps CF2016, CF11, CF10, or even earlier. How have the versions changed, in ways that some older code may not run on CF2021? And if you're skipping some CF version/s, what might have tripped you up in those, though not really "new" in CF2021 itself? And what can you do to mitigate such challenges?
In this session, CF troubleshooter Charlie Arehart will share from his experience helping folks make such migrations the past year (and for years with previous CF versions), whether in his role as an independent consultant or providing assistance to the CF community. He'll cover things you can consider in advance of the migration as well as things that might help during or after the migration. Most important, this talk will focus on the differences between CF2021 and various earlier CF versions. (Note that he has previously given a talk on migrating CF admin settings, and he plans a future talk on some other aspects of migration.)

ColdFusion at 25: not the kid most have stuck in their minds (View video , Show Description )As ColdFusion turns 26 next month, many seem stuck remembering it only as the "teen" they knew or even the "child", when instead it's grown up to be a capable "adult", impressive in many ways, and even more so recently. In this session, we'll look back at how CF has indeed evolved into a very capable platform, with quite modern features that seem to surprise many--including people working with it currently. If you struggle "finding CF people" or "getting buy-in", perhaps these observations could help you with both challenges. If nothing else, they're things designed simply to help you get your job done, while keeping up with modern practices.
We'll start with many modern coding techniques--which will be familiar to those using more "modern" languages but that many don't realize CF supports, and may have for years. We'll then look at ways things such as CF installation/deployment, configuration/administration, monitoring, security, and more have improved over the years. And we'll look not only at CF itself but the community surrounding it, ranging from resources for help and learning to tools and services that others have created, making CF a far more complete ecosystem than most give it credit. Put another way: it's not your father's CF!

CFMeetup: Installing CF2021: choices, challenges, and solutions (View video , Show Description )If you're considering moving to CF2021, there are some things to consider before or as you may install it. First, there's a new "zip" install option, in addition to the traditional full installer. What's that about? why should you use it? what are some challenges, and why might you not want to? We'll cover that.
Second, even with the full installer there are new options and choices, and perhaps it's been a while since you have installed even other CF versions. We will cover some of the key choices presented.
We'll also discuss aspects of migrating CF admin settings from an old version to a new, and touch briefly on the pros and cons of installing a new CF version alongside an old one.
There are certainly other challenges with installing ColdFusion, and we will also open the floor for questions about that and cover whatever else we can in the hour allotted.

Hidden Gems in CF2021 (View video , Show Description )It's that time again: another new ColdFusion version, and another chance for Charlie Arehart to reprise his classic "hidden gems" approach to finding what all is new that you might miss, like he's been doing since CF4.0.1. Some may be modest features that few would use, while others may be pretty bug deals but which just don't get much press. There are always FAR more new things with each release than people realize--usually several dozen (and CF2021 is no exception), then more that may come in updates to follow. Charlie will identify them, highlighting some, as well as discussing edition differences, pricing, migration issues, and pointing to resources for learning more.

CFMeetup: Differences between CF Ent & Std: more than you may think (View video , Show Description )Most people know that there are differences between CF Enterprise and Standard, most notably the price, of course! But if pressed, I suspect most people could not name more than a couple other differences or perhaps a few, but there are literally dozens. And while you may think you "don't need" Enterprise when it "costs so much more", you may be surprised to find some things that could in fact be "worth it" compared to remaining on Standard: whether from a performance standpoint, in terms of certain tags that are throttled in Standard; or from a licensing standpoint, in terms how many more CPU cores are supported by Enterprise than Standard. It may even be possible that it would be less expensive for you to license CF Enterprise rather than Standard.
In this session, veteran server troubleshooter Charlie Arehart will walk through the many areas that there are differences, some having to do with how CFML features may vary, or how CF Admin or even how CFBuilder features may vary. Is CF Enterprise right for you? Or is Standard "good enough"? In this session, it should become more clear for you, or at least you can be more confident/accurate about discussing the differences. Again, there's a LOT of misinformation/misunderstanding, as I watch discussions of the differences in the community. (And yes, of course, many will want to point out that there is the entirely free Lucee engine. If it suits your needs, that's an option. It doesn't suit everyone's needs, so it's not like it's "pointless" to discuss the differences between paying for CF Enterprises vs Standard.)
You may even learn about things that are possible in Standard that you didn't know where there, when discussed relative to or indeed as as an alternative to Enterprise-only functionality.

CFMeetup: Migrating or comparing CF Admin settings (View video , Show Description )Have you ever wished you could easily compare the CF Admin settings between one instance and another? Whether on different machines or multiple instances on the same machine, or even between one version of CF and another? What about between CF and Lucee?
And when you install CF, you may know that it offers to import Admin settings of a previous instance found on the same machine, but what if you need to migrate settings from one instance to another, again perhaps even between versions? Or what if you skip that auto-import and want to run it again?
In this session, veteran CF troubleshooter Charlie Arehart will walk you through all these scenarios, showing tools that are either built into CF or can be used for free, including one that's coming in the next release of CF (and which has been shown publicly already). One of the tools even helps with BOTH migration AND comparison between instances AND between CF engines! But each tool has its place and and may be new to you. Come see what's possible!

CFMeetup: Keeping CF (and Java) updated: challenges and solutions (View video , Show Description )Are you keeping up on whatever updates are available for the CF version you're running (2018, 2016, or so on)? And how about updating the Java/JVM that CF uses? You should be, for security as well as bug fix reasons. And what about the web server connector (wsconfig)?
Ever since CF10, the mechanism to update CF has been a single-click operation in the CF Admin--or at least, that's how it's supposed to be. But sometimes things go amiss, and you can be left with CF not coming up, or the admin not opening, or something in your app failing to work right which you may not notice for even days or weeks.
And the same is true when it comes to updating the Java/JVM that CF uses: there are several things you can easily do "wrong" that will have CF not starting. And even if you do it "right", there may be something amiss (because you missed an important step) that might not bite you for some days--when someone tries to make an https call out of CF. And you may wonder, "what version of Java can I use with my version of CF?"
The good news is that there are answers and a few key best practices to follow in updating CF, the JVM, and wsconfig, which if followed can ensure that each is a quick and painless task. In this session, veteran CF troubleshooter Charlie Arehart will walk through all this, based on his decade-plus experience in helping people troubleshoot such problems daily. The session will apply both to those using the Admin or command line for such update mechanisms.

Troubleshooting with FusionReactor, part 4: Post-crash Troubleshooting (View video , Show Description )In the previous sessions of this series we have talked about aspect of using FusionReactor which were focused on what it could tell you while problems were happening or starting to happen. But what if your monitored instance or server has crashed/restarted?
FusionReactor tracks up to 1 week's worth of information in the core metric graphs if the server crashed or restarts, this information is no longer available (as it's stored in memory). But FR still has the information in the logs and it's still available in the Archive metrics.
In this final session introducing troubleshooting, we will focus on the aspects of FusionReactor which can be used AFTER a crash/restart of your monitored instance. In addition to two features which have long existed in FR (alerts and logs), we will especially focus on two newer features that can dramatically ease the process of post-crash troubleshooting:
- Archived metrics
- Alerts and logs
- FR cloud: alerts and profiles
