Re: onApplicationStart and cfmail, when doess server start?
That is correct behavior. An application does not start until a page within its scope is requested. You have a few options though. Use onServerStart (CF 9+). Use another server to monitor it. Use a third party program such as FusionReactor. I highly recommend it and it's well worth the money spent.

Re: What event specifically triggers OnApplicationStart?
Ian Skinner - I owe you an apology. After studying the access logs from the web server, I can't say with 100% certainty but it looks like this happened because someone hit the web server using an IP address. They didn't use the password to force a call to OnApplicationStart so it must have been right after a server reboot. I've rewritten that code to be more robust. :-) ~| 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:343419 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
What event specifically triggers OnApplicationStart?
In Application.cfc, I know that OnApplicationStart is called when an application starts. I'd like to define that better. From what I've read, this is when the first page is requested from an app (also possible are event gateways and Flash remoting but I'm not using either). So, if I say: this.applicationTimeout = CreateTimeSpan(1, 0, 0, 0); in my Application.cfc and a day goes by since calling OnApplicationStart, isn't it true that the server doesn't invoke my code on its own (like a cron job). It waits for a day to go by and then invokes OnApplicationStart on the next page request - even if that request is hours later? I'm asking because I'm trying to track down some odd behavior in a customer's app. The OnApplicationStart code looks at CGI.SERVER_NAME to determine which config file to load (production, staging, dev, etc.). Twice in the last 6 months, the production system starts to think it's a dev system. Are there cases where CGI.SERVER_NAME could be empty or undefined or... when OnApplicationStart is called? Can I trust that CGI var's are always set correctly in this scenario? ~| 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:343352 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
Re: What event specifically triggers OnApplicationStart?
memory variables only timeout if they are not accessed the specified timeout period. every time anyone loads a page on your site, it accesses the application scope and their session scope, so the timeout is reset back to 0. An application will restart when ColdFusion restarts, when you reach the applicationTimeout, if you force a restart via code or via the CFADMIN/server monitor When you say you use cgi.server_name to determine which variables to use, are you being VERY explicity, as in the SERVER_NAME must match EXACTLY, or are you doing an if/else to say if its this then set as live else set as dev ?

Re: What event specifically triggers OnApplicationStart?
I think I can see one possible cause of your problem Dave. You may actually have 2 applications running. one on yourdomain.com and another on www.yourdomain.com So if someone goes to yourdoamin.com and then www.yourdomain.com they will NOT be seeing the same application. So perhaps most people go to www.yourdomain.com, but every so often someone visits yourdoamin.cominstead, which would restart the application if it was outside the timeout period. To avoid this you need to add a redirect, so that only 1 domain is in use. either redirect www.yourdoamin.com to yourdomain.com or vice versa.

Re: What event specifically triggers OnApplicationStart?
One thing to keep in mind, if you do not have a *unique *ApplicationName on your server, then the variables could be shared w/another application--which is especially dangerous on shared hosting. I've seen people roll out an application w/a common ApplicationName like MainApp and have issues w/their App scope being shared w/another application that also used a name of MainApp. Same thing happens if the Application.cfc/cfm doesn't define a ApplicationName. IMO, the safest thing you can do is name define ever ApplicationName with a hash of the current directory path: cfset this.name = hash(getDirectoryFromPath(getCurrentTemplatePath())) / That way you can use the same code w/every Application.cfc, but your virtually guaranteed to have a unique ApplicationName. -Dan On Mon, Mar 28, 2011 at 2:55 PM, Russ Michaels r...@michaels.me.uk wrote: I think I can see one possible cause of your problem Dave.

Re: What event specifically triggers OnApplicationStart?
I think I can see one possible cause of your problem Dave. You may actually have 2 applications running. one on yourdomain.com and another on www.yourdomain.com So if someone goes to yourdoamin.com and then www.yourdomain.com they will NOT be seeing the same application. So perhaps most people go to www.yourdomain.com, but every so often someone visits yourdoamin.com instead, which would restart the application if it was outside the timeout period. To avoid this you need to add a redirect, so that only 1 domain is in use. either redirect www.yourdoamin.com to yourdomain.com or vice versa. And also change your code to explicit to avoid this problem if CGI.SERVER_NAME IS blah.com else ... staging else ... dev else redirect to blah.com Russ - I'm not sure I follow 100%. Whether the subdomain is there or not, IIS is configured to point to the same docroot so the same code will execute. I thought that the code manipulated the same application object if this.name was the same (which it is regardless of subdomain). Or am I missing something? ~| 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:343364 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
Re: What event specifically triggers OnApplicationStart?
One thing to keep in mind, if you do not have a *unique *ApplicationName on your server, then the variables could be shared w/another application--which is especially dangerous on shared hosting. I've seen people roll out an application w/a common ApplicationName like MainApp and have issues w/their App scope being shared w/another application that also used a name of MainApp. Same thing happens if the Application.cfc/cfm doesn't define a ApplicationName. IMO, the safest thing you can do is name define ever ApplicationName with a hash of the current directory path: cfset this.name = hash(getDirectoryFromPath(getCurrentTemplatePath())) / That way you can use the same code w/every Application.cfc, but your virtually guaranteed to have a unique ApplicationName. -Dan Dan - That's a good tip but the app name is unique and I've verified that there are no unintended conflicts by dumping the application object's variables. (But, yes, I'm on shared hosting - meant to say that.) ~| 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:343365 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm

My diagnostic page only dumps the current config, not how it got there. I'm going to change that. Since I don't get an exception thrown within OnApplicationStart, I can assume that CGI is defined and CGI.SERVER_NAME is also defined.

Re: What event specifically triggers OnApplicationStart?
Which means that if I (or any joker poking at your site to see if they can do something) who requests your site by its IP address could set your production server into dev mode. Not necessisarily, that would depend on how the web server was set to handle requests. One of my application has a similar setup and IIS will only pass the request to the application if the IP and hostname bindings are correct. If you made a request on the IP itself you'd just get a 301 response with a redirect to the main URL. Of course, if you knew the dev URL you could get into the application in development mode (also assuming you had proper credentials), but you couldn't put the live application into dev mode just by tweaking the HTTP request. -Justin ~| 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:343371 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
Re: What event specifically triggers OnApplicationStart?
Is it possible that someone is accessing your site by it's ip address, in an attempt to fool it into something that could enable a hacking attempt? I've seen security scanning software do similar things. This is why I tend to have the production state be the default state, and have development and stage be explicitly defined. That way, if the system is not sure which configuration to use, it uses the most secure. Mark Sent from my mobile device.

Re: onApplicationStart
That's by design. CF knows when an application starts. You can 'force' it a few ways. 1) In CF9, within onRequestStart, add a check for url.init (or some such), and run applicationStop(), you then need to reload the current request. 2) Or even simpler, within onRequestStart, add a check for a url var and simply do onApplicationStart(); This will NOT single thread the call, but if you are just setting up a bunch of variables, you most likely do not need to be concerned. 3) I don't really recommend this, but you can also just rename the application.

Something a bit simpler may be to use the ApplicationStop function. From QuickDocs: http://cfquickdocs.com/cf9/?getDoc=applicationstopDescription Stops or resets the current application. The application is restarted on the next request to the application. As a caveat, its CF9 only so far. hth, larry You can have a cfif looking for a url variable such as reset.

Re: onApplicationStart Vs onRequestStart
OnApplicationStart runs the first time ANY user hits your site. It's commonly used for setting application variables that rarely change. Things like datasources are a good place for that or initializing a ton of cfobjects. I commonly put a cfif statement in my onRequest event to reset the application variables. like this: cffunction name=OnRequest cfif isDefined(attributes.resetVars) cfset onApplicationStart()/ /cfif /cffunction That way if you can rerun the function from any request.

Hi Sherif, Welcome to the community. :) The onApplicationStart and onRequest start events are simply events which occur at a given time and aren't actually tied to any variable scopes, other than the fact that onApplicationStart executes immediately after the application scope is created. But you can do whatever you want to in that method. For example, you can create request variables in the onApplicationStart method, even though it executes before onRequestStart. So the lifespan of an application looks like this: 1. onApplicationStart 2. onSessionStart 3. onRequestStart 4. index.cfm 5. onRequestEnd 6. return to 3 (onRequestStart) and repeat 7. onSessionEnd - user timed out 8. return to 2 (onSessionStart) and repeat for other users 9. onApplicationEnd - application timed out 10. return to 1 (onApplicationStart) the next time the site is visited You can use application variables in index.cfm -- they need to be properly scoped, but if you set them in the onApplicationStart method they should be available. Your onApplicationStart method may not be executing if you haven't specified a name for your application. So your Application.cfc should look similar to this: cfcomponent cfset this.name = myapplication / cffunction name=onApplicationStart access=public cfset application.ds = myDataSource / /cffunction /cfcomponent You can also look to see what variables you have in your application scope from your index.cfm template by dumping the structure like this: cfdump var=#application# / hth -- s. isaac dealey ^ new epoch isn't it time for a change? ph: 781.769.0723 http://onTap.riaforge.org/blog ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;207172674;29440083;f Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:313193 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4

For Example what does it mean by Application? First time a user comes to your site? Does it only run once? I tried to set a Variable in the onApplicationStart method like cfset APPLICATION.ds=myDataSource/ and I get an Error when I say use it in index.cfm. Am i allowed to use this outside in other files Or anything that gets set in onApplicationStart gets passed to onApplicationEnd and thats where the variable get used? Thanks. Hi Sherif, Welcome to the community. :) The onApplicationStart and onRequest start events are simply events which occur at a given time and aren't actually tied to any variable scopes, other than the fact that onApplicationStart executes immediately after the application scope is created. But you can do whatever you want to in that method. For example, you can create request variables in the onApplicationStart method, even though it executes before onRequestStart. So the lifespan of an application looks like this: 1. onApplicationStart 2. onSessionStart 3. onRequestStart 4. index.cfm 5. onRequestEnd 6. return to 3 (onRequestStart) and repeat 7. onSessionEnd - user timed out 8. return to 2 (onSessionStart) and repeat for other users 9. onApplicationEnd - application timed out 10. return to 1 (onApplicationStart) the next time the site is visited You can use application variables in index.cfm -- they need to be properly scoped, but if you set them in the onApplicationStart method they should be available. Your onApplicationStart method may not be executing if you haven't specified a name for your application. So your Application.cfc should look similar to this: cfcomponent cfset this.name = myapplication / cffunction name=onApplicationStart access=public cfset application.ds = myDataSource / /cffunction /cfcomponent You can also look to see what variables you have in your application scope from your index.cfm template by dumping the structure like this: cfdump var=#application# / hth -- s. isaac dealey ^ new epoch isn't it time for a change? ph: 781.769.0723 http://onTap.riaforge.org/blog ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;207172674;29440083;f Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:313195 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
Re: onApplicationStart Vs onRequestStart
The whole point of putting variables into the application scope is to cache them so you don't have to set them on every request. The reason your variables didn't get set after you added new ones was that your application had already started; OnApplicationStart doesn't run on every request. mxAjax / CFAjax docs and other useful articles: http://www.bifrost.com.au/blog/ 2008/9/29 Sherif Abdou Oh Ok I found what the problem is, I guess my Varaibles in the onApplicationStart got cached, so when I sent it once, launched and then I added another Variables after launched again the application variables dont' get updated.

You can have a cfif looking for a url variable such as reset.

Re: onApplicationStart
No, not really. I put all my initialization logic in a separate method of Application.cfc, and then invoke that method from onRequestStart if certain conditions are met (usually the presence of a reloadApplication URL param that is set to a specific value). Note that this doesn't expire the application, it just reinitializes it. So any pre-existing application variables will continue to exist unless your initialization explicitly overwrites or deletes them. cheers, barneyb On Jan 3, 2008 12:01 PM, Adkins, Randy [EMAIL PROTECTED] wrote: Question: When using the onApplicationStart within an Application.cfc, lets say I wanted to restart the Application to pickup some changes.

Re: onApplicationStart
You can try putting most of your OnApplicationStart code into cfinclude files and call those cfinclude file in some other reload page. This has an advantage over calling OnApplicationStart again if there are some things that OnApplicationStart does that you don't want to do a second time, such as reinitializing a list of logged-in users. If you just want to reload some application-scope variables or some cached functions, calling the entire OnApplicationStart again might be overkill. Another way to do this is to put conditionals in the OnApplicationStart block that only reinitializes certain sections depending on the input variables (commonly a URL variable). My guess is that you don't actually want to expire the application in order to reload a few variables. If you do want to expire the application, there are ways to do this. Setting the application timeout = 0 is one way. -Mike Chabot On Jan 3, 2008 3:06 PM, Brian Kotek [EMAIL PROTECTED] wrote: You can just call onApplicationStart() again, but be aware that it won't be thread safe as it is when the application starts up.

That's not necessarily true if there are multiple variables and the integrity of the code relies on them not being set inconsistently. In other words, race condition *can* still apply here depending on how atomic the initialization code is... As for the CFC, if you have init code like this: application.someVar = createObject(component,MyThing); application.someVar.someMethod(42); then that may well not be safe either - in particular if someMethod is actually init! - because the application code may depend on someVar being in at least the state that someMethod() puts it in (and other requests could access application.someVar after the createObject() but before the someMethod() call). A safer way to do that initialization is: var someVar = createObject(component,MyThing); someVar.someMethod(42); application.someVar = someVar; i.e., fully initialize the component before placing it in application scope. -- Sean A Corfield -- (904) 302-SEAN An Architect's View -- http://corfield.org/ If you're not annoying somebody, you're not really alive. -- Margaret Atwood ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:295800 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
Re: onApplicationStart cftry
It was pretty serious at the time. Seemed to be a problem with the JVM garbage collection but is sorted now. It affected a handful of sites connecting to the SQL server. One of them was failing on the connection storage for the client session varaibles, so I was thinking if this ever happened again it'd be good to be able to test for it in the code.

Hi, I've seen a few examples where this happens, but, I'm a little confused as to why you'd use cftry/cfcatch to test for a DB connection within onApplicationstart.

Wouldn't it be better to have this test within onRequestStart?

Re: onApplicationStart cftry
I think the idea is to cache the check and not rerun it on every request, which could be wasteful. It is a trade off. I'd probably use onRequestStart, and cache the last check time, and only check once an hour.

Because if you don't restart CF then the Application is already started and onApplicationStart will never fire.

RE: can't get onApplicationStart to fire...
Slight amendment The below should read Because if you don't restart CF then the Application is already started and onApplicationStart will never fire. The Application starts on the first request to the CF server that requests that Application.cfc (or another template that contains the cfapplication tag with that application name) after the CF server is started. - Calvin -Original Message- From: Calvin Ward [mailto:[EMAIL PROTECTED] Sent: Friday, February 11, 2005 7:02 AM To: CF-Talk Subject: RE: can't get onApplicationStart to fire...

Re: can't get onApplicationStart to fire...
You may also want to consider a very low app timeout while testing. You may also want to consider putting something like this in your onRequestStart: if isDefined(url.reinit) onApplicationStart() Unfortunately, this will only run you rmethod. It will not reset the Application like a true restart. But in most cases you don't really care. I've already bugged MACR about adding a real way to programatically restart an App/Session.

Re: can't get onApplicationStart to fire...
But I'm using createUUID() as the application name to ensure the application always starts on every request... (I'm only doing this cos i got bored of changing the name everytime i tweaked Application.cfc to try and get it to work) And either i'm using the same session, in which case session.startup should already be set, or its a new session, in which case it should be set. Or am i missing something?

Re: can't get onApplicationStart to fire...
I'm confused now: I'm i right in thinking that onApplicationStart()
should fire automatically when the application starts?
And by application starting i mean the first time a cfapplication
tag with a particular application name is run (assuming server has
just restarted).
If thats correct then i can't get it to work: my onApplicationStart()
never fires.
Or am i supposed to call it manually:
ie
cfapplication name=myApp
cfif NOT IsDefined('application.started')
cfset onApplicationStart()
/cfif
Cheers

No, you don't need to call it manually.
Does it work if you use Application.cfc to set the app paramaters?

Re: can't get onApplicationStart to fire...
Aha - thats what i was missing. So in order to use the onApplication and onSession methods you need to initialise the application in application.cfc, except instead of using the cfapplication tag you set the the parameters in the This scope. In other words, Application.cfc replaces both Application.cfm and cfapplication (unless you only want to use the onRequest methods) Thanks Bert On Fri, 11 Feb 2005 22:29:51 +0800, James Holmes [EMAIL PROTECTED] wrote: Does it work if you use Application.cfc to set the app paramaters? http://livedocs.macromedia.com/coldfusion/7/htmldocs/1115.htm ~| Discover CFTicket - The leading ColdFusion Help Desk and Trouble Ticket application http://www.houseoffusion.com/banners/view.cfm?bannerid=48 Message: http://www.houseoffusion.com/lists.cfm/link=i:4:194264 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
