[cfaussie] Coldfusion FORM scope randomly missing variables

[BarryC]

Hi,

I have a form scope issue that has me stumped.

I have a non coldfusion script on a 'server A' which posts data to a
coldfusion script on 'server B'.
The form scope on server B sometimes does not pick up that something
has been posted to it and is therefore empty. This seems totally
random and I cannot see any reason why this would happen.

I've tried this on three seperate coldfusion boxes with both
coldfusion 7 and coldfusion 8. the script I am posting to is a simple
 I've tried pointing the script on 'server A' to
a php script on another server and it works fine, so it seems to only
be a coldfusion thing.

Any ideas?

Thanks
Barry Chesterman.

[cfaussie] Re: CF Error Submitting An Interactive PDF to CFML page

[BarryC]

Maybe there are some characters in the string you are sending it that
it doesn't like.
Have you tried setting up a simple PDF form with a single field that
posts to a page?

are you able to see what the query string is that is actually being
processed given that it stops at the function parseQueryString()?

those 500 illegal argument errors are a bit tricky to work out :)

[cfaussie] Coldfusion and JRun server loads

[BarryC]

Hi, I'm not sure what most people have as a Coldfusion configuration,
but we run Coldfusion on windows servers using JRun4, we use IIS as
the web server and Jrun4 is set up as a connector.

I'm currently load testing and trying different values for the maximum
simultaneous threads, thread pool size, backlog size and timeouts.
I'm wondering if anyone here has had experience configuring these
values or knows enough about them to share some advice on them.

Here are some values I have at the moment (these aren't the same as
what we are using in our production environment).

activeHandlerThreads 60
backlog 500
maxHandlerThreads 500
minHandlerThreads 1
timeout 60
threadwaittimeout 60

What I'm trying to do is get a good balance for normal server use, and
also have the server not get bogged down and fall over if it gets
flooded with too many requests at one time (we do have a proxy server
in front preventing DOS attacks etc, but of course it doesn't prevent
legitimate cases of high usage)

I've seen around the net that Linux recommends about 200 to 400ish
maxHandlerThreads but windows servers can have 1000 to 3000 (which
seems odd, because I'm not convinced that windows could schedule that
many threads)

Any ideas / thoughts?

[cfaussie] Re: cfthread - can I see if a thread is still running

[BarryC]

You could just store a value in a persistent scope such as the
application scope.
When your ZIP thread completes, have it write a value to the
application scope (such as a date/time stamp).
The FTP thread can just check that value is set, if it is, then it
knows the ZIP thread has completed.

[cfaussie] Persistent Scopes and Memory

[BarryC]

Hi,

I have a quick question.
Does data in the application and server scopes get stored in the
"tenured" generation memory, or the "permanent" generation memory?

There seems to be conflicting statements all over the net about this,
and I was wondering if anyone could clarify it.

Adobe's website says this:
Tenured generation--This pool holds objects that live for a longer
duration. In ColdFusion this space holds objects like Client and
Session scope variables.
Permanent generation This pool holds persistent objects. In ColdFusion
this space holds permanent objects like Application and Server scope
variables.
(from 
http://www.adobe.com/devnet/coldfusion/articles/coldfusion_performance_02.html)


That statement goes against many which say the "permanent" generation
only stores class information or 'reflective' information

Thanks
Barry

As Gavin mentioned, firebug should do what you need.

Look in the 'Net' tab and it will give you a 'waterfall' view of all

[cfaussie] Re: Problems with webservice

[BarryC]

Care to post the actual web service function you are actually calling?
Normally that error means that the function you are calling does not
have its 'access' set to "remote" (in the case of coldfusion anyway),
or that function does not have those parameters available that you
passed to it.

[cfaussie] Calculate variable size in bytes

[BarryC]

Hi,

Does anybody know if there is a way in coldfusion (or the underlying
java language) to calculate the size of a variable in bytes?

I want to calculate the size of a struct in bytes, but I cannot find a
way to calculate it and there doesn't look to be any function that
does it?

Thanks :)

[cfaussie] Re: Persistent Scopes and Memory

[BarryC]

Just in case anyone is interested,

Today I did a test to answer my original question; "Does data in the
application and server scopes get stored in the
"tenured" generation memory, or the "permanent" generation memory?"

I found that Application, Session and Server scopes all stored their
'data' in the "Tenured" generation space. The "permanent" generation
is in fact used just for information about the data, 'classes' etc.
Our site is in fact very large (university website) with lots of
different classes, and our "permanent" generation was only using about
50 meg of the 250 meg allocated for it.

Note that we run JRun4 with the Sun 1.4.2 JVM and Coldfusion 7.

for tracking down a memory issue.

I have a suspicion that we are actually storing too much information
in our application scope, so I want to be able to run a script to spit
out the current size of the application scope, and possibly parts
within the application scope.

[cfaussie] Re: Calculate variable size in bytes

[BarryC]

oh, so that actually lets you see scopes like server, session,
application to see what overall size they have, and sizes of things
within them?
I was under the impression that you could only see the low level data
in memory.

If that's the case, then I'll give it a go :)

[cfaussie] Re: Trying to consume .Net Webservice

[BarryC]

Is there any directory authentication going on such as .htaccess or
IIS NTLM authentication?
Can you paste a copy of the error you get when you request the web
service?

a .Net web service should be just like consuming any other web
service, as web services are supposed to be a standard protocol.

[cfaussie] Re: Session timeout errors.

[BarryC]

I'm not sure what web server software you are running on, but if it's
IIS, could it be the session time in that? (not that I've had any
issues with IIS session times)
Also, just on the off chance, you haven't put the timeout numbers in
the wrong boxes, or the wrong values in the session input boxes in the
coldfusion administrator have you? (just in case you haven't already
double checked)

[cfaussie] Coldfusion 7 with JVM 1.6 and Verity

[BarryC]

Hi,

I was wondering if anyone here has managed to get Verity search to run
without error using JVM 1.6 (or anything over 1.5) on Coldfusion 7.
It is not officially supported to work with JVM 1.6 but i'm wondering
if there is a work around.

For the most part verity is actually working, but you can't manage
collections from within coldfusion administrator (throws up an error).

Any help would be great, but I'm not actually expecting a solution for
this as it's probably fairly uncommon.

Regards
Barry

[cfaussie] Re: CF7 (and 8) High CPU usage on production box

[BarryC]

There are many ways to go about finding what's going on in Coldfusion.
Elaborating on what Kai was mentioning about metrics/garbage
collection/memory..

Have you had a look in the logs from the JVM and ColdFusion to see if
there are any error messages that might be related?

The first thing you could do is turn on logging of long running
requests (somewhere in coldfusion administrator)
That might give you some clues as to what pages could be causing more
load / cpu usage.

Enable logging of metrics to see if you may have too many active
handler threads (concurrent running processes of requests), you may
need to configure some settings to optimise these values.

The second thing you could do is do some thread dumps (you can do this
either with a utility - there is one called StackTrace' or you can do
it manually from a command prompt after you manually start coldfusion)
Do several heap dumps every 10 seconds and see if there are common
functions or pages coming up in the thread dump (the things that need
more processing should come up more frequently in those logs).
Thread dumps are generally used if you find you are getting
bottlenecks in your application and you need to find what parts of
your app could be doing the bottlenecking. So if you aren't getting
long running pages then you may not need to do this.

If you think it's memory related (and if you are getting tight on
memory for your application, that will cause more 'Major' garbage
collection events using more CPU) then you can enable garbage
collection logging, a free analyzer tool called GCViewer
http://www.tagtraum.com/gcviewer.html lets you get a graphical view of
what's going on as a memory overview. If it looks like you have a
memory problem, then you can generate heap dumps and use something
like the Eclipse memory analyzer plugin (MAT) to view the heap dump
log.
Google will tell you how to generate heap dumps.

An awesome profiling tool that I found very useful was Oracle's
Jrockit Mission Control (used to be owned by BEA or something
arather). It's free for development and you can do profiling with that
and see pretty much everything that's going on in coldfusion.
You do have to update your config file to point to that though, and it
could be slightly dodgy running it in a production environment, it's
more something you use in a development environment.

There's a lot to learn when it comes to the under the hood performance
and memory stuff but it's quite interesting and very good to know as a
developer how all that stuff works.

[cfaussie] Coldfusion, Taking a thread dump when response times increase?

[BarryC]

Hi,

Does anyone know if there is a way to generate a thread dump
automatically when server response times increase? I know how to do
one manually, but that's no good if I'm not around when the response
times increase. Does FusionReactor do this by any chance?

Thanks
Barry

[cfaussie] Re: CF7 (and 8) High CPU usage on production box

[BarryC]

If you're stumped for optimisation of a long running task, then having
a scheduled task is a great idea, but even when the scheduled task
runs, unless it's optimised it could still cause a performance hit.
An idea might be to put a 'thread wait ()' in your loop to allow other
things to run otherwise it will try and run the loop as quickly as
possible.
Coldfusion 8 has a built in tag for that, for Coldfusion 7 or earlier
you need to call the a java thread function which is straight forward
but you need to google to see how to do it.
Depending on your environment, any heavy tasks are always worth
shifting off your production environment onto a separate one (and push
the result to production). Not always feasible tho :)

[cfaussie] Re: CF7 (and 8) High CPU usage on production box

[BarryC]

GCViewer as Kai mentioned is a good one, I have used that and it gives
you a good graphical view of when collections are happening.
http://www.tagtraum.com/gcviewer.html

Makes it really easy to see when major GC's are happening :)

It does have a real time view where you can watch it as it logs (but
i've found that a bit buggy) alternatively you can just load a log
file from several hours and just view that.

[cfaussie] FusionReactor vs built in Coldfusion 8 monitor

[BarryC]

Hi All

we are looking at getting FusionReactor, but will be upgrading from
Coldfusion 7 to Coldfusion 8  in several months.
How does FusionReactor compare to the Coldfusion 8 monitor tool built
in to the CF Administrator, does it provide much on top of the
Coldfusion 8 monitor, or is it worth just waiting till we upgrade to
Coldfusion 8?

Thanks
Barry.

[cfaussie] Coldfusion7 to Coldfusion8, JVM config

[BarryC]

Hi,

We are migrating from Coldfusion7 to Coldfusion8 and I wondered if
anyone was up to date on the config parameters for the JVM for
Coldfusion 8 (JRE 1.6.X) and has some recommendations.

What by the way (if somebody knows) is
Dsun.io.useCanonCaches or
DJINTEGRA_NATIVE_MODE or
DJINTEGRA_PREFETCH_ENUMS
and are any of those three required for CF8?

The following is the config line we use for our Coldfusion7
environment (seperated for easy reading):
java.args=-server
-XX:+UseParallelGC
-Xmx1450m
-Xms1450m
-XX:PermSize=110m
-XX:MaxPermSize=110m
-XX:NewSize=256m
-XX:MaxNewSize=256m
-Dsun.io.useCanonCaches=false
-DJINTEGRA_NATIVE_MODE
-DJINTEGRA_PREFETCH_ENUMS -
Dcoldfusion.rootDir={application.home}/

The following is what we have for our Coldfusion8 environment:
java.args=
-Xmx1450m (heap size to be tested, not implemented yet)
-Xms1450m
-XX:PermSize=110m
-XX:MaxPermSize=110m
-XX:NewSize=256m
-XX:MaxNewSize=256m
-Dsun.io.useCanonCaches=false
-XX:MaxPermSize=192m
-XX:+UseParallelGC
-Dcoldfusion.rootDir={application.home}/

Thanks
Barry Chesterman

Thanks.

We are in the process of running it in a test environment :)

[cfaussie] Re: CFBuilder

[BarryC]

You can easily import projects into CF Builder (there is an import
option somewhere through the right mouse menu in the project/navigator
panel).

I've tried the CFBuilder plugin in Eclipse and in Flash Builder
(Eclipse also) In normal eclipse it didn't work at all (but I think
that was to do with my eclipse version). In the Flash Builder eclilpse
install it seemed slow and frequently hung for about 5 mins or so.
I ended up installing a standalone CFBuilder to see how that goes
instead but I've found I have to turn off all the auto building,
project refreshing and on the fly error checking.

I'm pretty sure you can add other eclipse plugins into CFBuilder
tho :)

[cfaussie] Coldfusion XML, adding an XML node from another XML document object

[BarryC]

Hi,

I've hunted around for a solution to this but haven't found a simple
or clean one (maybe there isn't one) but maybe someone here has some
suggestions.

I have two XML objects and I want to take an XML node from one and
insert it into the other

XML Object 1:


  
background
#FF
  


 
border-color
#00A0AF
  


I want to take the  node in XML Object 2 and add/insert it into
XML Object 1 so I end up with this result:
