CFMeetup: Lessons Learned Configuring ColdFusion 10 on Windows View video , Show Description )Let me show you some things I have learned since ColdFusion has changed from JRun to Tomcat. In this presentation you will get an overview about ColdFusion 10, Tomcat, Connectors and how those interface with a web server. You will be shown some effective ways to freely monitor the ColdFusion10 environment.

CFMeetup: JVM configuration and CF View video , Show Description )The JVM underlies CF operation, so optimal configuration can often have significant influence on how well CF runs. How does the JVM use memory and perform garbage collection? How does one monitor the JVM? And what are the effects of JVM configuration options on the CF environment? Answers to these questions should be of interest to anyone who administers a CF system.

CFMeetup: Options for running Redis (or Valkey, etc.), locally or as-a-service View video , Show Description )You may be considering use of Redis (or alternatives like Valkey), whether for caching or as a document store/db or as an alternative repository for sessions (such as is an option for ColdFusion sessions since CF2016). But before you can USE Redis you need to have some IMPLEMENTATION of it. In this session, veteran server troubleshooter Charlie Arehart will review different approaches for implementing Redis (and/or Valkey, and other plug-compatible replacements): with most approaches being free, while some come at a cost.
We'll review options first for installing it (including challenges and solutions for Windows machines), then options for running it via Docker/containers, or finally on a VM (or WSL). Then we'll identify cloud service implementations of Redis, and not only from AWS, Azure, and GCP, but also online services focused specifically on offering Redis (or alternatives) as-a-service--some free and some at a cost. Different options will appeal to different folks, but you really can be at least testing/demonstrating your possible use of Redis within minutes, for free, and that's the main motivation for this talk. (I have another talk focused more on using Redis for sessions in CF and Lucee. This talk supplements that one.)

CFMeetup: CF Scheduled Tasks: there’s more than you may know View video , Show Description )If folks were asked to discuss CF scheduled tasks, I suspect most would feel "there's not much to say". But there really is a lot more to working with them than simply "setting a given url to run on a given schedule" (did you know it could be a CFC, for instance? Did you know about the cron time feature? Did you know about clustering scheduled tasks--even with ColdFusion Standard?). Besides there being more features than many may realize, there are also some common problems people face when running them, and there are tools and techniques to help with that.
In this talk, veteran CF troubleshooter Charlie Arehart will address all these and more, starting with several ways to create them (yes, even more than just cfschedule and the CF Admin UI) then more on those more advanced/easily missed features, as well as tools and techniques for solving common problems with them. We'll also explore configuration files and features for managing tasks. Finally we'll also cover ways CF scheduled tasks may NOT work well and discuss alternatives to them.

CFMeetup: Migrating CF Admin settings between versions, safely View video , Show Description )When moving from one CF version to another (or even to the same version but from one machine or instance to another), someone will face the need to "bring along" the CF Admin settings, including such things as datasources, scheduled tasks, mappings, and so on. How can that be done quickly and safely? (Note that you should NOT just "copy over the neo xml files", nor must you "open two tabs/screens and start copy/pasting between them".) Did you know there are a few different ways to migrate admin settings safely--one of which is new starting with CF2021?
In this session, veteran CF troubleshooter Charlie Arehart will walk through these options, some old and some new, some built into CF and some freely available. We'll also cover briefly COMPARING CF Admin settings between two CF instances--again, other than just eyeballing two tabs/screens--as such a comparison can be very helpful to check things whether before or after such a migration.

CFMeetup: The Many Capabilities of CF Package Management and cfpm View video , Show Description )You may or may not have heard that CF2021 added a new tool called cfpm, the ColdFusion Package Manager. It was introduced in CF2021, and while some are aware that it can help manage the new modular packages-based design of ColdFusion, many are unaware of the many features of this cfpm tool--and how this package management mechanism can be used to their advantage.
In this talk, veteran CF troubleshooter Charlie Arehart will introduce the feature (CF's package-based design and the package manager), including identifying the way it can manage the packages used in a current CF instance as well as in automating creation of new instances. Perhaps most useful, we'll see how the tool offers a mechanism to SCAN your CFML code base to identify what packages you would need. We'll also see how the tool can help with updating CF, as well as managing the update download "repo". And speaking of updates, we'll discuss ways the cfpm/package mechanism has evolved in updates since the release of CF2021 and in CF2023.

CFMeetup: Updating the Java underlying ColdFusion: considering it, doing it View video , Show Description )With Java updates now happening quarterly (and one just this week), it's important that ColdFusion administrators and/or developers keep up to date on the Java version underlying their CF (or Lucee) deployments. The simplest question may of course be "how do I perform such a JVM update, effectively"--and it really can be quite simple. But there's a good bit more to updating Java (aka the jvm, jdk, jre).
In this session, veteran troubleshooter Charlie Arehart will share his experience helping people deal with this topic about weekly for many years, including:
Considering and planning for the jvm update: On the many "current" JVM versions; what jvm do you have, what can you update to, and why should you
Performing the jvm update: where to get it, which one to choose and 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, and regardless of whether you deploy these traditionally or via Commandbox or even containers, most of this presentation will apply to you.

CFMeetup: Installing CF2023: choices, challenges, and solutions View video , Show Description )If you'll be installing CF2023, there are some things to consider before or as you do. First, be aware that besides the traditional full installer there's the new "zip" install option (added in CF2021). What's that about, why might you want to use it--or not?
Then there are are some options and choices during installation--some new also with CF2021. Perhaps it's been a while since you've installed even previous CF versions. We'll cover some of the key options to consider (including license activation, package/module management, and more) as well as post-install steps including updating CF and the JVM, and migrating in CF Admin settings (including using the new CLI/json admin config tool, cfsetup).
In this session, veteran CF troubleshooter Charlie Arehart will share his experience helping folks install CF thousands of times, including several dozen installs already of CF2023. We'll conclude with discussion of alternatives to installing CF (some which you may know about, some maybe not). We'll also open the floor to questions about other topics we might discuss in the time remaining.

CFMeetup: Migrating apps to ColdFusion 2023 from earlier versions View video , Show Description )While CF2023 has been out since May 2023, many orgs may only now be considering moving to it, whether from CF2021 or especially CF2018, CF2016, or CF11. Naturally, folks considering such a migration will wonder how have the latest version might affect affect existing code. But perhaps you're also skipping some CF version/s in your move: what might have changed in those versions (which would have tripped you up then) which would affect you now in moving to CF2023? And what can you do to mitigate such challenges? What tools and resources might help?
In this session, CF troubleshooter Charlie Arehart will share from his experience helping folks make such migrations the past several months (and for years with previous CF versions), whether in his role as an independent consultant or in 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 CF2023 and each of the past few CF versions that you may be migrating from. (Note that he has previously given talks on migrating CF admin settings, that you should consider also.)

CFMeetup:The Many Ways to Run CF or Lucee View video , Show Description )Depending on your experience you may tend to favor running CF and your CFML the way you've "always done it" (perhaps by installing CF or Lucee, or perhaps via Commandbox). But did you know there are in fact several ways to deploy CF or Lucee, including ways to run CFML without even needing to do that? In this session, veteran CF consultant Charlie Arehart will identify these, starting first with WHY it's useful to have different ways to be able to deploy CF/Lucee and CFML.
Then he will discuss and demonstrate those several ways--whether you prefer to run CF on your own machine or another (whether hosted or in the cloud), to include even being able to run CFML WITHOUT need of CF or Lucee to be "installed" at all. He will cover such topics as installers (GUI and console-based), silent installation (and updates), Commandbox, WAR file deployment, container-based (Docker/Kubernetes) deployment, serverless deployment, as well as CLI-based execution of CFML, and execution via cffiddle and trycf, among others.
Buckle up, buttercup, for a fast tour of this varied landscape.
