Re: asynch cfml gateway - working example
Windows hosts files? Potential external/unknown variables? Hmmm... What you are talking about? Give me a potential point of break. Merely that the http protocol is designed to provide communication between disparate systems, and as such the http request leaves the current system to initiate activity on another. In this case the other system happens to be the same current system, and of course, this is how the CF task scheduler has worked for quite some time. Yes, the odds are that a request from the current machine to itself won't fail, but it still potentially involves a windows hosts file, router, dns server... By comparison, a CF7 asynchronous CFML gateway is executed entirely within the context of the JVM -- it never leaves the system and so doesn't have those other things as potential points of breakage. As an (unlikely but theoretically viable) example, if you had 3 servers hosting the domain mydomain.com and had the IP address of one of these machines in the windows hosts file of the other two for that domain, then you wouldn't be able to connect to the current machine on that domain with an http request. If I were building a windows-only application which needed to use a lot of http I would certainly consider this tag as an option. Multithreading assumes cooperation between different parts of a task. So-called async gateways are just parallel and NOT cooperating DIFFERENT tasks. If this is what you want, try CFEXECUTE first. I'm not sure what you're getting at (or how it has anything to do with the questions I was asking)... I'm also not sure why you feel the need to talk down to me... Although the Asynch CFML gateway isn't inherently designed to produce cooprative tasks, using it to produce cooperative tasks isn't particularly difficult. Check out Sean Corfield's articles : http://corfield.org/blog/index.cfm?do=blog.searchsearch=Concurrency+l ibrary (I seem to have deleted the email from the guy who recommended these to me before and can't remember who it was now, but I wanted to say thanks.) Cfexecute isn't necessarily the best solution either for a number of reasons, not everything is available on the command line (although in this case we're talking about CF requests and iirc MX makes that available, though I've never used it), command line arguments vary between operating systems, etc. s. isaac dealey 954.522.6080 new epoch : isn't it time for a change? add features without fixtures with the onTap open source framework http://www.fusiontap.com http://coldfusion.sys-con.com/author/4806Dealey.htm ~| Logware (www.logware.us): a new and convenient web-based time tracking application.

RE: nevermind -- asynch cfml gateway - working example
It's a Unix plain text file. What exactly was virtually illegible about it? If you open a Unix text file with the Windows application Notepad, you won't see the intended newlines because of the difference between the way newlines are handled on Windows and Unix. Windows uses ASCII characters 13 and 10, while Unix just uses 10 if I recall correctly. So you get one big line with a bunch of unprintable characters in it.

I suppose the answer is, 'it depends', but curious on thoughts on this. The CF7 administrator allows you to assign the number of threads available to the gateways (all gateways share one pool, not just asynch), and the number of gateway requests to queue. By default it's 10 and 255 in developer mode. Not sure if the defaults are different for pro/ent. I suspect the thread pools are separate (one for gateways, another for http requests), though even if they share the same pool, the fact that the long running process(es) are passed off to a different thread should cause the spawning request to complete faster and thus release that thread sooner for the next request waiting in queue. In terms of mechanical efficiency there shouldn't be much difference -- the machine is performing the same tasks either way. But mechanical efficiency isn't really the purpose of asynch cfml -- it's purpose is to provide faster response times and as a result better experience to end-users. s. isaac dealey 954.522.6080 new epoch : isn't it time for a change? add features without fixtures with the onTap open source framework http://www.fusiontap.com http://coldfusion.sys-con.com/author/4806Dealey.htm ~| Logware (www.logware.us): a new and convenient web-based time tracking application.

Re: asynch cfml gateway - working example
Windows hosts files? Potential external/unknown variables? Hmmm... What you are talking about? Give me a potential point of break. Multithreading assumes cooperation between different parts of a task. So-called async gateways are just parallel and NOT cooperating DIFFERENT tasks. If this is what you want, try CFEXECUTE first. Looks nice, although I wouldn't use it for asynch processing...

Re: asynch cfml gateway - working example
I have not been able to play with this stuff yet, but D. Cooper's blog entry had this Imagine spawning off long running DB queries in parallel, for example. Page response times for most existing CF applications, in fact, would probably have some place that could make use of such a capability to dramatically make the user experience better. I'm really curious on how this could be accomplished. How can you break up one long running query to run in parallel?

What he's describing is either executing a long-running query without interrupting page delivery (if the query results aren't needed for display), and/or executing multiple queries simultanously (which may or may not be long running). But as the API for asynch doesn't natively provide the ability to return a response from the gateway to the calling page (something Sean's tools are designed to accomplish), the gateway isn't really designed with the intent of gathering content needed to deliver the current request. Rather it's designed primarily for features such as logging application activity to a database which can sometimes slow page delivery without providing any content for the user during the current request.

Re: asynch cfml gateway - working example
um, that's what I thought. Was chatting with coworkers today about this too. Their concern was thread use. Threads used in the async gateway are part of the pool in the JRun instance, no? So, if you have a box getting good load, introducing a script that runs in this parallel fashion, this would eat up more threads, eh? So, is it really beneficial? I suppose the answer is, 'it depends', but curious on thoughts on this. DK On 6/6/05, S. Isaac Dealey [EMAIL PROTECTED] wrote: I have not been able to play with this stuff yet, but D.

If I recall correctly, the gateway has its own thread pool, separate from the threads that are used to service regular requests.

asynch cfml gateway - working example
This just isn't my week... I'm guessing there's not a working exmaple of the asynch cfml gateway included in either of the example apps included with the Getting Started Experience since the only 2 gateway instances pre-installed were both SMS. Does anybody have some working code I can test with. I was certain I'd managed to get this CFML gateway to work ... once... and only once ... after that nothing, and no errors... with no significant changes... I've checked the cfc path in cf admin, i've restarted the gateway instance, I'm not passing a cfcpath element in the event data structure... and yet, without any errors being produced, I can't get the gateway cfc to either write to file or write to the cf logs... SendGatewayMessage() does return false some, but it also returns true at least as much. Errors occurring within gateway events are still reported in the Application.log right? That is -- the eventgateway.log only reports errors instantiating the gateway instance right? I was thinking this was just the same problems I've been having with the log files (which -- as it turns out, the log files consistently become deleteable again in windows [no sharing violation] after restarting CF Server) -- but I can't get the cfc to write to a text file with cffile either -- even when SendGatewayMessage returns true and no error is reported (which might be because of the log file issues). s. isaac dealey 954.522.6080 new epoch : isn't it time for a change? add features without fixtures with the onTap open source framework http://www.fusiontap.com http://coldfusion.sys-con.com/author/4806Dealey.htm ~| Find out how CFTicket can increase your company's customer support efficiency by 100% http://www.houseoffusion.com/banners/view.cfm?bannerid=49 Message: http://www.houseoffusion.com/lists.cfm/link=i:4:208636 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4 Donations Support: http://www.houseoffusion.com/tiny.cfm/54
