Re: [cfaussie] Best JVM version to use with CF9
It depends. .24 is as people have said - the latest, officially supported version. People have reported running it successfully with later releases - I'd personally do that if there's a particular bug fix or improvement you want to take advantage of.

RE: [cfaussie] Best JVM version to use with CF9
I'm not aware of any particularly impressive performance increases, no, at least not for those on CF 9. Of course, those on CF 8 or 8.01, who were still running 1.6.0_04 or earlier by default WILL see a performance increase by getting past the bug fixed in _10 (discussed in the blog entry), but the JVM in CF 9 and 9.01 is past that. So to your original question (the best JVM to use with CF), I was just focusing on the benefits of that authorized update to _24, for all the improvements it may offer (security, functionality, etc.) now that it was specifically supported by CF. That said, if anyone would wonder, I'd say that it's rare (in my experience as an independent CF troubleshooting consultant) that changing the JVM itself has ever been a vital solution to solving CF performance problems (except in that case of getting CF 8/8.01 past update 1.6.0_10). On the other hand, if one is facing performance challenges (and if that may have been why you were considering it Steve), there are many other usual suspects which are more likely.

RE: [cfaussie] Best JVM version to use with CF9
So following up my note below, I was talking about how changing the JVM is rarely the key solution to solving CF performance problems (except that one instance of the JVM bug prior to 1.6.0_10). I was saying that there are many other more usual suspects. And really, they are hardly ever about code. Instead, it's nearly always configuration (whether of CF or something it connects to, like the web server or database server), and/or that config may be challenged due to unexpected traffic (load or nature) that has not been contemplated. The key is to know what's really going on inside CF. And for that I always help my clients focus on using key diagnostics, whether built into CF by default (and more than most realize) or easily added for free. This can be logs, command line tools, monitors, emails generated by them, and more. Once you can find and use them, you can generally (perhaps with help at first) connect the dots to solving the problem. Again, it rarely ends up being about changing code, but instead configuration. Or just about better understanding how CF runs, and when and why requests take a long time, what they are waiting for, what they want to talk to, what may be generating more requests than you expect, what's creating more sessions than you expect, and so on. And some may notice I have not mentioned tweaking the JVM or GC algorithms, as is often proposed (and passed around, almost like trading cards). I know that some people (on this very list) will be able to offer some specific case where that was indeed THE one change that fixed things for them. But in my now hundreds of engagements to help solve problems, it's been the solution in maybe one or two. Honestly, I find that many recommendations to do that (or that focus on code tweaks to try, etc.) seem to come often from a stance of not having taken full advantage of available diagnostics, so that CF has felt like a black box and people are just willing to try what they can, until something works. And if CF's running poorly, just restart it. Those sort of solutions are so common in our circles as to rarely be challenged. I'm just stressing that a better approach is to find the right diagnostics, study them, connect them with others, identify the real problem, fix it, and repeat the process until the major (or perhaps a few key) problems are resolved. I realize that my pushing this point will make me seem a tall poppy to some (somehow I can't fail to raise that feeling in certain people, whenever I write). I just want to encourage people to look outside the box when facing challenges. Or more specifically, to look INSIDE the box more effectively. I plan to create some more targeted resources focused specifically on better CF server troubleshooting. Until then, besides my assisting people via consulting, I also do it via lists, my blog, presos, and articles. More at www.carehart.org. Back to your note, Steve, I realize that you may not have been missing or misunderstanding any of this yourself. You simply asked about possible performance increases from a JVM switch. :-) I just wanted to use it as chance to offer this additional encouragement (and perhaps different perspective for some readers), in case it may be helpful. (Off to bed for me now, so no replies until the morning, if needed.) And to those attending CF.Objective(ANZ), have a great time. (About 14 folks attended the daylong pre-conference class I did on this very topic last year. If you're hear and want to chime in on whether this approach has worked, please do.) /charlie From: cfaussie@googlegroups.com [mailto:cfaussie@googlegroups.com] On Behalf Of charlie arehart Sent: Wednesday, November 16, 2011 11:56 PM To: cfaussie@googlegroups.com Subject: RE: [cfaussie] Best JVM version to use with CF9 I'm not aware of any particularly impressive performance increases, no, at least not for those on CF 9.
