sirTangale, I have not heard of that being a limitation. Do you find it documented somewhere?   My understanding is that the ability of the redis client to handle a "moved" response from redis is a built-in feature of the jedis library cf uses. I've not explored what jedis version adds that support, and different cf versions can have different jedis versions--perhaps updated in a cf uodate, in fact.   But Kane refers to being on cf 2016. Kane, are you really still stuck on that, which last got any updates (including security updates) in 2021? That's a grave risk. Then also you could run into such issues6  with the old libraries it includes.   I've not yet tried myself to connect cf sessions to a Redis configured as a cluster, and I'd like to try it just to be sure.    But until then, Kane, here's another idea to consider: do a test of a cf page that you open in a new incognito/private window in your browser (or clear all your cookies). I'm wondering if cf may handle things better when it creates a NEW session and then redis implements that in its cluster member. That may cause it to better track where it is, thus preventing the MOVE operation. That's just a guess.   Finally, what is the version of the REDIS server you're connecting to? That may also have a bearing on things here.  ... View more

Yep, so you should find that this is resolved by simply a) stopping cf, b) deleting the cfusion/bin/felix-cache, then c) starting cf and testing of your datasource now works. We look forward to confirmation of success or failure.   And if it works, the big lesson (for all) to take away is the importance of reading the update technotes. Yes, it's like flossing. 🙂 I'll add that I also do a blog post on each update when they come out, where I highlight things that folks should pay attention to.

Thanks for the update. It makes me change my mind. I no longer think that the messages indicate an error. What makes me change my mind is the fact that you get the messages when ColdFusion starts or stops. Therefore the messages could be related to ColdFusion's package management.   You probably missed my last suggestion. I hope it will give us a clue: what happens when you manually create the directories C:\CF2021\ContentInstance2\wwwroot\WEB-INF\services and C:\CF2021\ContentInstance2\wwwroot\WEB-INF\modules, and then restart the ColdFusion instance? ...

Rick, as is often the case, there's what may seem a "simple answer" but then more to it, which some will want to be aware of.   To be clear there is no "feature" or "setting" in the CF Admin which will reflect if you have implemented this "patch"--in the sense that an admin page will refer to enabling this logging, if that's what you may mean. But there IS at least a way to know if this (or any such special hotfix) has been applied.   1) If you look at either the "system information" page (via the "i" icon in the top right of the admin) or the "settings summary" page (via the first "server settings" section on the left), those pages report dozens of things, one of which is the "CF Server Java Class Path" for CF--and it lists what jars were found IN the variously defined class paths, as found by CF at its startup.   And if you do a browser "find" on either of those pages for the string "8888", that is how name of the jar begins, as downloaded from the Adobe technote about the patch (like the hf202300-8888889.jar filename for the CF2023 version of the file.  If it's found, it's been loaded by CF; otherwise, it has not. (And note that these will NOT show the file if you have placed the jar file in the lib/updates folder but have not yet restarted CF.)   You should also see in that list the chf*.jar that corresponds to whatever CF update level you're on. BTW, it's a bit odd that the Adobe technote referred to this hotfix as a "patch". All past such things were called "hotfixes", as indeed is indicated by the hf in front of the name of the jar here. (And the "chf" means "cumulative hotfix".)   2) One last thing: some may want to point out that the two pages above also offer an "update level", which some argue is "how you can know what update has been applied". That is not a complete statement: this reported value only ever shows ONE jar of any found in that lib/updates folder. If you have two or more, you will only see ONE. Granted, you MAY see this special hf file there, but it's just not reliable as what I proposed above (because in fact this WILL list files found in that lib/updates folder--even if you have NOT yet restarted CF!).   FWIW, the challenge of this listed "update level" is not new.  I had blogged about it back in 2012 in a post on helping people determine what update level they were on--which was all the more challenging for those then still on CF9 or earlier. I also reiterated it in a 2019 post I did on dealing with such "special hotfixes" as this one. And that's also where I warned how they are REMOVED during any subsequent update, but can be reclaimed from the hf-updates "backup" folder for the applied hotfix. 🙂   Hope that's helpful. ...

I'll try to create a cf2023 update of that specific compose file, and will confirm it works then will post it in the repo.   As for yo/down vs stop/start, I hear you feeling the latter is more common. I've not experienced that, but we can have differing opinion. I'll also try to test doing that, in case I might learn anything to help you with. Or perhaps someone else already will know.   Finally, it's not new that the pdfg has been in a separate service. It's always been since it (and cfhtmltopdf) came out in cf11. More important to your concern here, it's been a separate process launched within the container setup since Adobe created the docket images originally with CF2016.  ... View more

I realize this is a few days after your original question, but assuming the problem remains (and beyond the ideas shared so far by bkbk and Dave), I want to turn our attention to your presumption that this a "cf2023" problem. Until you can offer a test case that allows us to prove that ourselves (between our own cf2018 and cf2023), I have a different question.   You say your cf2023 is on docker on aws. What's your cf2018 setup? Is it also a docker image? (Adobe did offer docker images for cf2018 originally.) Either way, it at least also on aws? (There could be some facet unique to that which would not happen otherwise.) Is the OS st least the same between the two cf instances (I don't expect that should change how the features work. I'm just helping consider possibilities.)    Indeed, are both cf instances talking to exactly the same database, and using the same driver type in cf? And what are your update levels for cf2023 and 2018? In particular, are you testing cf2023 update 11, since that has dozens of bug fixes. (And yes, Adobe has released a container image with update 11 pre-installed which should make it easy for you to try.)    I realize you may not want to "play 20 questions ". As I said, if you could offer some small example code (that is standalone and allows us to recreate your results) that could let us skip most of those considerations, if we could confirm it was SOLELY about cf2018 vs cf2023. Until then, perhaps these will help you find the cause of your different behavior.  ... View more

... I am going to convert all of our cfgrids to datatables . Thanks By @forrestmahannah   Wise move. That will help future-proof your code.   For some years now, the general advice in the ColdFusion community is to avoid using Coldfusion's UI tags, of which cfgrid is one.  See, for example, https://github.com/cfjedimaster/ColdFusion-UI-the-Right-Way . There you will find a practical example that uses Datatables as an alternative to cfgrid.   ... View more

Thanks for the response, Charlie. That idea makes sense, especially since I updated the JDK about 3 weeks ago on all our ColdFusion servers. I checked the logs though just to see if I made a mistake, but it looks like when I ran the update, I stopped the CF application service at 10:01:31 AM, installed the JDK, then started the CF application service at 10:03:21 AM. It came back up fine, and as far as I know, there had been no other updates on the JDK until this issue.   We do have a patching service in place on that server though, and while I confirmed it didn't touch the JDK on this last patch, I wasn't able to find out if it could have run an update before. Just to be safe, I did configure the patching service to exclude the Java folder going forward.   Have you ever seen any other service or application maybe lock up the Java 11 install? We do run OpenOffice on our servers too for cfdocument support. Although I suppose the could be using it's own JVM? ... View more

Hi @Madhabdhk ,  When you say you have "increased the RAM from 8 GB to 16 GB", do you mean you have increased the maximum heap size (Xmx) in ColdFusion from 8 GB to 16 GB? If so, then the situation still needs to be improved.   The Operating System's RAM is 16 GB. If ColdFusion's maximum heap is 100% of the Operating System's RAM, there will again be problems sooner or later. That is because ColdFusion will starve Windows of memory resources.   You can solve this in one of two ways:  Use for ColdFusion a maximum heap size (Xmx) that is lower than 16 GB. Say, a value in the range 12 to 14 GB. However, a Java application may, on rare occasions, use more memory than assigned on the heap. So we're still pushing it a bit here.    Increase the RAM on Windows to 32 GB or more, and use for ColdFusion a maximum heap size (Xmx) of 16 GB or more. FusionReactor will tell you just how much memory your application needs, to which you can add a margin.   I personally prefer the second option. It is more flexible, sustainable and future-proof.   On the subject of heap size, there is yet another point to consider: setting the initial heap size (-Xms) and the maximum heap size (-Xmx) to the same value, for example, -Xms16g -Xmx16g or -Xms12g -Xmx12g By default, Java adjusts the heap size dynamically between the (-Xms) and (-Xmx) values, as needed during runtime.  It might be that, on your system, Java does a lot of heap-resizing when the ColdFusion Launcher runs.  ...

@ronj46336389 , thanks to Charlie for revisiting this thread. In the time since your thread I found a way to reproduce the error you saw ( "coldfusion.document.webkit.PDFgErrorHandler$ConnectionVerificationFailedException: Connection verification failed." ). Finding that also led to a solution.   A - To reproduce the exception:   1)  Go to the PDF Service page in the ColdFusion Administrator. There you will see the PDF Service Manager, together with its domain name and port number. 2)  Click on the button to Verify All Service Managers. You should then see a Connection Status of OK. An OK means your settings are fine. In that case you are in a position to do the experiment of reproducing the exception.  ( Otherwise, the port number is probably incorrect. In that case, proceed to section "B - To find the correct PDF Service port number, hence solve the problem". ) 3) Click on the button to edit the PDF Service Manager. Doing so should automatically prefill the Add/Edit form: 4) Change the port number in the form, for example, by reducing it by 1. Here, from 8996 to 8995. Then press the button to Update PDF Service Manager. You will see that the registered PDF Service Manager is now listening on the new port. 5)  Click on the button to Verify All Service Managers. You should then see an error: If you view ColdFusion's exception.log, you will see the following error message:   "Error","http-nio-8500-exec-2","10/16/24","13:54:06","cfadmin","Connection verification failed.

OK, this took quite a bit of time, but we've narrow it down to rare instances when a function includes its own arguments as part of its return payload.   The Redis cache apparently doesn't handle this?   Take this code example we made up and just sent to Adobe:   <cfset cacheKey = "ThisIsATest123"> <!--- <cfset cacheremove(cacheKey)> ---> <cfif isNull(cacheGet( cacheKey ))> <cfset fromCache = false> <cfset testData = {}> <cfset testData = WTFFxn("test1","test2")> <cfset cachePut(cacheKey, testData , createTimeSpan(1,0,0,0),createTimeSpan(0,1,0,0) )> <cfelse> <!--- <cfset cacheremove(cacheKey)> ---> <cfset fromCache = true> <cfset testData = cacheGet( cacheKey )> </cfif> <cfdump var="#fromCache#"> <cfdump var="#testData#"><cfabort> <!--- --------------------------------------------------------------- ---> <cffunction name="WTFFxn"> <cfargument name="wtf1" required="true"> <cfargument name="wtf2" required="true"> <!--- If returned like this: Redis ERROR ---> <cfset ret = arguments> <!--- If returned like this: Redis ERROR ---> <cfset ret.wtf1 = arguments.wtf1 > <cfset ret.wtf2 = arguments.wtf2 > <!--- If returned like this: Redis OK ---> <cfset ret = { wtf1 = arguments.wtf1, wtf2 = arguments.wtf2 }> <cfreturn ret> </cffunction>   We're calling the 'WTFFxn" function which simply returns the arguments we send in.  We tried 3 methods of returning: Simply sending the arguments right back out, ret = arguments, results in the Redis 'error' Assigning the arguments to a new structure using dot notation, results in a Redis 'error' However, if we reassign the arguments to a new structure using curly braces, this is handled properly by Redis cache   Bizarre, and we normally don't return arguments in this way, but we found this code leftover from a dev's troubleshooting a completely different issue!   Again, this only happened to us when using Redis caching.  EHCache handles it no problem.   Anyway, seems like a bug.  I've reported to Adobe support and will also submit it as a bug.   Are others able to reproduce this? ...
