Application_End

Ido
Hi,
If asp process is being recycled/restarted gracefully, will Application_End
allways be called?
In addition, according to :
http://www.codecomments.com/archive2...-2-393853.html one can understand
that Application_End may not be able to finish its execution before the
process is shut-down. That does not sound reasonable to me. What d'you say?

Thanks,
Ido

Hi Ido,
If asp process is being recycled/restarted gracefully, will
Application_End allways be called?
When the worker process is recycled, it is shut down, which means, yes,
Application_End will be called.
In addition, according to :
http://www.codecomments.com/archive2...-2-393853.html one can
understand that Application_End may not be able to finish its execution
before the process is shut-down. That does not sound reasonable to me.
What d'you say?
Well, Scott *is* an MVP, but first, to be fair, he didn't state
authoritatively that he knew how much time the process would have to shut
down. He guessed.

I'm not surprised that he guessed either. It took me over an hour to run
down this information for you. Luckily, it's Sunday! Here's the straight
dope:

When the ASP.Net worker process is shut down, there is a time limit set on
how long the server will wait before shutting down the process. How this
time limit is set on an IIS 6 box depends upon the execution model being
used for ASP.Net. By default, ASP.Net apps run in IIS 5 "Worker Process
Isolation Mode." This means that each worker process is run in an IIS 6.0
Application pool. The "Health" tab of the Application Pool Properties dialog
box is used to set the "Shutdown Time Limit" for that pool. This corresponds
to the "shutdowntimeou t" value in the <processmodel > section of the
machine.config file, which is used in IIS 5 for all ASP.Net applications,
and in IIS 6 ASP.Net applications running in "IIS 5.0 Isolation Mode."

It should be noted, of course, that one cannot guarantee that the code in
the Application_End method of the global.asax class will complete before the
time limit is reached. Good programming practice would dictate that you
handle the eventuality that it doesn't. Bottom line is, whenever you use
memory to cache data, make sure to account for the eventuality that the data
will disappear for one reason or another.

My .Net book states that the Application_End event handler in Global.asax gets called typically about 20 minutes after the last HTTP request.

I assume that if I put a breakpoint in my Application_End code, and then run the...

I have a small asp.net web app running on a shared host. It uses a Jet (Access) database. I included a routine to compact the database when the application_event fires if it has not been compacted for a certain period of time. A compact must be done into a new file. In other words mydb.mdb compacts into mydb2.mdb. The original file (mydb.mdb) then gets deleted and mydb2.mdb is renamed to mydb.mdb. This routine works fine on another shared...

I am trying to shutdown a database server in the Application_End event handler on the Global.asax page. So far I am trying this only on the development server that comes with Visual Studio 2005. When I close the browser, this does not cause the Application_End event to trigger. It also will not occur when I shut down the development server. At this point the application is no longer running, so why didn't the event handler ever get called?...
