Re: Schedule task more frequent than 1 inute
Thanks for all the replies. Some background info. My app converts Office documents and each conversion may run for a few minutes which is why I did not want to run this 'inline' but break the upload away from the conversion. For this reason I have a scheduled task that checks the database for new uploads and then converts them. 99% of the time there will not be a new file, but when there is then I'd like to minimise the time between upload and conversion start. I considered threads but heard that there is a limit on CF Standard - potential headache if things get busy. Schedule the same task as many times per minute you need, starting at different times. I thought that too but what happens on server restart? Do all tasks re-init themselves at the same time? In the end I think once a minute is ok, but I will also ping now the page that handles the conversion shortly after the upload is complete. Out of interest: am I correct in thinking that if one task is running a conversion and the scheduled task fires again then this second process will not have to wait for the first conversion process to complete? So in essence I can achieve a level of multithreading in this way?

So in essence I can achieve a level of multithreading in this way? This is generally true for CF processes. However, it may not be true for things like converting documents - those things rely on functionality outside of CF that may well be single-threaded. Honestly, I don't know enough about how document conversion is handled in CF to answer that definitively, but if there are any problems you'll see them in testing.

IEvent Gateway's are not restricted to CF Enterprise anymore, they're part of the standard feature set - don't know when they did that, but they are available in CF8 Standard. DirectoryWatcher is a specific type of gateway... the Simple Interval Gateway is a custom gateway written in java that you put on the server, then in the admin console go to Gateway T ypes and add it, THEN go to Gateway Instances and add the specific instance of the gateway for your purpose.

Re: Schedule task more frequent than 1 inute
It's not possible AFAIK. Depending on your task, an EventGateway might be what you're after - if not, then I think you'll need a scheduling solution outside of CF.

There are several ways. Not in ACF that I am aware of. Off the top of my head You can set up a scheduled task in Windows and point it @ wget. Or in *nix you can use run a cron job or use something like Portable cron on windows. http://wiki.uniformserver.com/index.php/Portable_Cron HTH G!

Excellent point, you beat me to it. We have a couple of apps that needed really close occurring tasks (pre event gateways) and this is how we handled it.

Schedule the same task as many times per minute you need, starting at different times. Out of curiosity. Do the tasks fire off one exactly one minute after they are submitted or at every minute xx:xx:00? I am assuming they do. Thanx G!

Re: Schedule task more frequent than 1 inute
I would create a page that is scheduled to run every minute. That page would call an external request via CFHTTP, CFTHREAD or whatever could spawn a new CF request. Then, it would sleep for however long (20-30 seconds, for example) then call itself once or twice more. Then, in the next minute, that page is requested once again and the process repeats. mike ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:339740 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm

Re: Schedule task more frequent than 1 inute
Is there any way to schedule a task in CFadmin more frequently than once a minute? I need to run it 2-3 times minute if possible. Some people have already mentioned you can use threads and sleep, etc. However, I'd recommend that you take the task out of CF entirely, if possible, and implement it using your OS task scheduler. You'll generally get better performance that way, with less impact on the regular web serving tasks of your web application.
