JDBC/Cold Fusion to 8.1.6 DB

I'm using the 8.1.7 JDBC client on a Win2K Cold Fusion Server. The client connects to the database, but frequently hangs in the midst of a simple query. When I look at the task manager in Windows, the jrun process has maxed out at 99% with very little RAM being used. I'm trying to figure if this is a JDBC problem or a java runtime bug.
anyone have suggestions?

Update: I am running the rmjvm.run( true ) procedure to remove the jvm install. This is hanging as well. It creates the 'MONSTER' rollback segment, via the initjvmaux.rollbacksetup call, but then hangs (it appears) after that...I'll let it run a bit longer but this getting very frustrating is to say the least (of course, I have said more @()$*&@$(*#&!!!).
If I do a fresh install on the same machine, same parameters, and everything works then Oracle needs to work on their conversion utilities...and I thought their problems were just limited to their GUI tools...oh well. Oh yeah, perhaps a class action lawsuit against big O for loss of productivity because their conversion utility didn't work as documented. Don't get me wrong, best DB on the market, unfortunely, that's where their success ends in my opinion.

How not to use Cold Fusion and Java

Overview
This write up is intended to give java developers that are
developing ColdFusion applications some beneficial information:
things that are not documented.
Scenario
The company builds enterprise class web application software
for fortune 500 companies. It had purchased a CF 7 based product,
had and existing proprietary J2EE based product, and needed to
integrate the two while meeting a host of new requirements. These
requirements were based on delivering a better user experience,
faster / cheaper integration, increased flexibility /
configuration, useablily, decreasing maintenance costs, the ability
to deploy in either install or ASP models. An initiative was
started to create a new framework that integrated the best of each
technologies. Tactically, this meant that we were to build a hybrid
CF and java application: one that used building blocks (decoupled /
cohesive components) that would allow applications to be rapidly
assembled, configured and deployed. This made sense on several
levels, the team was composed of Java and CF developers, the CF
rapid application development was very productive, there is great
functionality delivered in the CF platform and initial performance
tests showed no cause for alarm
The agreed upon design, based on requirements, and analysis
by both the CF and Java staff has us using CF in the presentation
layer, using a CF based MVC, use of CF based web services. The MVC
was deployed using CFC inheritance for model objects and views made
use of CF custom tags. The internals of the application, used a
rules engine, some proprietary java, ORM, and other J2EE
technology. The initial performance of the system was reasonable.
We pushed on with product implementation.
Then it was time to load test the application, and tune it.
Under load the response times were orders of magnitude slower,
sometimes the pages even timed out.
Armed with our profiler, oracle execution plans and we
charged ahead addressing issue after issue. Note that we took
meticulous care in tweaking the active thread pool and ensuring
that our CF setup was tuned for our application. None of the
observations here are a condemnation of the language; rather they
are aspects that, when considered together, not conducive for
building integrated java and CF frameworks that use a structured /
OO programming practices. Further detail can be provided on
request.
CFC inheritance should be avoided - resolution of variable
scope is expensive even if properly declared.
Since CF creates a class per method under the covers call
stacks become very large, especially if used in a loop. This is
nominally exacerbated by CF calls necessary to set up for the
method call (String.toUpper()).
Nesting of loops and if statements should be kept to a
minimum - the conditional for each lookup of logical operator like
LT, GT are synchronized. Under load this results in thread waits.
Jrun has as single thread pool - both http and web service
requests use the same pool. Under load this leads to thread
deadlock. There are work arounds, but they are painful.
Recursion should be avoided - we had a few recursive routines
and these had to be rewritten.
Custom Tags - should be used sparingly - each custom tag
makes a synchronized call to the license server - (This may be
fixed in CF 8)
Summary
In the end we got the performance to reasonable numbers, but
we ended up moving some code to java (Custom Tags) and getting rid
of 'good programming' practices (Inheritance, loops, etc), mandated
proper variable scoping for those things left over. We prototyped a
sans cold fusion implementation and had an order of magnitude
improvement in performance and number of requests served per
second.
The lesson? Use Coldfusion in its sweet spot: make a query,
iterate over the results and format for display. Extensive use of
structure programming techniques or OO CFCs should be avoided: they
will work but under load - but are better as a prototype. Building
frameworks in CF? Think twice, no three times, and, if you must, be
minimalist.

interesting aslbert123,
Not that I doubt you, but could you answer some questions
about your implementation that was so slow:
1.) Did you put your CFCs in the application or server scope?
2.) Were you initializing your CFCs, via CreateObject or
<cfinvoke>, on every request?
3.) Are you sure that you were properly Var'ing every
variable in your methods? (people typically forget about query
names and loop iterator variables)
4.) Could you give examples of how your inheritence was set
up?
5.) For CustomTags, did you call them the old <cf_tag>
way or the newer, better-performing <cfimport> way?
6.) How did you connect CF to Java exactly?
Thanks,
Aaron

Need to dial a phone number from Cold Fusion

My boss asked me if there was any way that a phone number
could be dialed from Cold Fusion. We have a website where at some
point we want to just click a button and dial that phone number. My
guess is that the conversation will then be carried through the
computer's microphone and speakers and using the computer's modem.
Let me know if there is a way, or what would be the easiest
way to accomplish this, even if it has to be using VOIP, since
that's an option for this project.
Thanks!

Is this an internal site or an public-facing site? If you are
talking about using this tool in your intranet and you have a
modern phone system in place, there may be an API to interfacing
with your phone system. We use a TAPI interface to create a phone
dialer so our callcenter agents can dial a phone number on their
phone just by clicking on a link. I'm pretty sure there are a bunch
of freeware/shareware TAPI COM objects you can use floating around
the interwebs (If your phone system supports TAPI).
If you are talking about a public-facing website, then I'm
afraid I can't offer much advice other than to check out the Java
Communications lead that Ted gave you.

How do you determine what version of PHP is on the cold fusion server

I am trying to find out what version of PHP is on my cold

PHP?

In the C:\Windows folder, locate the file called php.ini and
open it in Notepad.
<?php phpinfo() ?>
I answered it myself. Maybe it can help someone else.

Modifying cold fusion script not picked up by iis

We are running coldfusion 7, using iis6 on windows 2003 server. I am not a cold fusion developer and this is the only coldfusion script we have created by a previous developer. I needed to make some simple modifications to the script, including a change in the title. After having restarted IIS the modified script is still not showing the new title. What do I need to do for iis to show the changes in the cfm file?

It's in the CF Administrator, which is separate from the JRun Admin Console. You can often get to the CF Administrator with a URL like this:

Cold Fusion in a generic thread pool and enabling JAVA don't mix

I've got Cold Fusion MX installed on a server running Sun One 6.1. I ran into a problem trying to enable JAVA (for servlet support) which I had previous disabled because I didn't use it.
Well, when I went to enable JAVA on the server last week, the service wouldn't restart and the error logs gave me no indication of the problem.
Through a tedious trial-and-error process I've found that having Cold Fusion running under a generic thread pool while trying to have JAVA (the j2ee plugin) running under Sun One simply doesn't work (for whatever reason).
Once I killed the pool, everything runs fine.
Does anyone happen to know why this is? I keep CFMX under its own thread pool because there are certain elements to CFMX that aren't wholly stable and can result in CFMX crashing. If it crashes, the process keeps accepting requests, but never processes them. I'd like to keep the native thread pool free to keep accepting non-CFMX requests even when CFMX crashes.
Thus the separate thread pool for CFMX.
But now I can't run CFMX in a separate thread pool with JAVA enabled.
Anyone have any insights into why this is?
Thanks

Two things. Firstly, it's better to use private static final Object classLock = new Object();because that saves you worrying about whether any other code synchronises on it. Secondly, if you do decide to go for the delegation route then java.lang.reflect.Proxy may be a good way forward.

How to convert/download videos embedded with cold fusion?

Does anyone know of a free video conversion software that will convert and download online videos embedded with cold fusion ("cfmid=?") format/extension? I tried a few online sites and they do not support that format yet. Please help. Thank you so much!
Judy

Actually COLD FUSION was a hoax a few years ago. COLDFUSION is the app.
If you need content from a web site, talk to the developer.
fwiw - Since ColdFusion is an Adobe app, you should try asking your question on that forum. This one is here to primarily support Shake.
Have fun.

Cold Fusion Mac Compat?

Can you run the latest Cold Fusion version in association
with CS3 Web Premium for Mac on a Mac without a Windows
shell?

Scooter,
I use a Macbook Pro (OS X 10.4.9) and run CFMX 7.0.2 (on top
of JRun 4 and NOT as a standalone web server) with no issues. I
also have CS 2.3 Premium on my machine. I will be getting CS3 in
about a week or two when it releases but there should be no issues
whatsoever with this configuration.

Xp pro config question with cold fusion(newbie)

Hello,
I'm a beginner and I want to learn studio mx 2004.In trying
to learn Macromedia MX for windows ,I've gone thru the installation
process in the manual for installing Cold Fusion for the server
side of things.My question is, I'm not sure if IIS is mnadatory in
order to use cold fusion.Is it a case of using one or the other or
is the IIS service required to run Cold Fusion? Also im using cold
fusion5 is cold fusion mx = to cold fusion 6.1?

Thanks for answering. Is there any benefits to running both
servers? I
don't want to confuse myself with too many
options.Essentially,I could
learn Dreamweaver (my ultimate goal) by using either
installation.
No, while it is possible to run multiple versions of CF, it
takes extra
configurations to do so. I would say this is unnecessary for
just
learning. I would strongly suggest upgrading. CF 5 is the
oldest and
most limited version of CF still officially supported by
Adobe. The
latest version is 7.0.2. There is a huge, major, complete
rewrite of CF
and many other bug fixes and enhancements between CF 5.x and
the current
version.
The current version and all versions of CF are free for
download from
Adobe for a personal development copy. If you do so now,
before you
start writing code, the upgrade install IIRC is quite
painless and will
use the configurations you have already chosen.

How to change web server from inbuilt Tomcat to IIS in already configured Cold Fusion 10

how to change web server from inbuilt Tomcat to IIS in already configured Cold Fusion 10

You just need to run the Web Server Configuration Tool to connect ColdFusion to IIS. It can be found in the ColdFusion program group off of the Start menu. Be sure to run it "As Administrator".

Flex/cold fusion wizard & Visual Query builder has a problem

has anybody tried the cold fusion / flex application wizard in flex 3?
to get there follow these menu choices:
file new other cold fusion wizards coldfusion / flex application wizard
I previously installed cf8 and the rds query viewer works fine.
i simply choose from the following menus:
window other views... Cold Fusion RDS dataview
i was initially prompted for the rds password which i entered.
in the RDS Dataview, I can see the tables, columns, and data for all my existing datasources.
Unfortunately, when I use the COld Fusion/Flex application wizard,
I get to the page layout and design screen, add a page with the name artists, choose page type master, and click the Edit master page button.
Nothing happens when I click the Edit Master Page button. I followed the cf/flex tutorial exactly but there is no query builder.
I dont know if this is related but in the RDS query viewer, the Visual Query BUilder doesn't work.
I think this may be the problem (the visual query builder has a problem)
Unfortunately, how do I fix this problem

already found the answer
flex has to be run as administrator if using WIndows Vista
simply shut down flex, right click the startup icon, choose run as administrator, and the visual query builder runs fine.
Dont know why this occurs because you are always prompted for the rds password.
anyway, problem solved.

suggestion/help is really appreciated.

I am really interested about this topic. I am in the same

How to call C through Cold Fusion?

I have some legacy C code.Does anybody know how to
call it from Cold Fusion?
Thanks!

Depends on what it does and how you need to interact with the
code. Do you have the option of simply passing arguments and
retrieving output via CFEXECUTE? Is it something akin to CGI that
may require using the CFX framework?

Cannot browse server following installation of hotfix 4 to Cold Fusion 9.0.1

Hi
I've been tasked with updating a ColdFusion 9.0.1 installation to the latest patches. I've started with Hotfix 4. The installation appeared to go OK, and the services started after I applied the update. However, when I went to moved onto the next update (APSB13-10) starting by browsing to the update file I ran into a problem. When I click on the "browse server" button to locate the .jar file for the next update I encounter an error: "Unable to authenticate on RDS server using current security information". I've also found that if I try to put the full path into the Update File line and hit "Submit Changes" it errors.
This seems to be the same problem as http://forums.adobe.com/message/5256752#5256752, but there's no solution to the problem in that discussion.
I've checked the RDS settings, and RDS is unchecked. I notice that this screen is different from the pre-upgrade screen, but this seems to be as a result of, I think, APSB13-03, which is included in HotFix 4. If I try to make any changes on this screen it errors and logs me out of the Cold Fusion administrator. I've tried commenting out the RDS section in the web.xml file, but this gives me a different error.
I'm doing this on an isolated test server which has no access to the network. If I revert to the snapshot I took before the upgrade attempt ColdFusion runs as expected.
Any ideas what might be the problem? Thanks in advance.

In case it helps anyone I've realised what I was doing wrong here.
The main “problem” was that one of the updates included in Cumulative Hotfix 4 is APSB13-03 (http://helpx.adobe.com/coldfusion/kb/coldfusion-security-hotfix-apsb13-03.html). I knew this changed the behaviour of RDS but my knowledge prior to this work of ColdFusion and in particular RDS was very limited, and so I didn't understand the implications of this hotfix. What this update does is disable RDS by default; I wasn't really aware what the RDS status of my server was prior to the update, partly because before this update there is no "disable RDS" tick box to show whether it is enabled or disabled. With RDS disabled, you can't browse as the update instructions require you to do. Obviously RDS was enabled on my setup without me realising it.
My understanding of this wasn't helped by the fact that when I tried to paste a path into the box and hit the "update" button I got a different error, which I described in my original post. Similarly if I tried to change RDS settings, or do pretty much anything in the administrator, it failed and logged me out in the same way. It seemed to me that the whole thing was broken by the updates and I didn't know how to fix it.
So, following the excellent advice of Charlie Arehart in two articles: http://www.carehart.org/blog/client/index.cfm/2010/12/12/cfmyths_cumulative_hotfixes and http://www.carehart.org/blog/client/index.cfm/2011/10/21/why_chfs_may_break, I went back to the start and installed the cumulative hotfixes one by one. Although I don't think I actually needed to do this, as Hotfix 4 seems to contain all the previous hotfixes, it did help me realise that the browsing/RDS issue and the error and logout when I tried to do anything in the administrator were two different problems. After further bit of googling I found people suggesting that you should use https to access the administrator, but the shortcut I had was taking me to http (as far as I know I was using the default shortcut). I found that by going to https the problem of being logged out when trying to do anything disappeared and I could put a UNC path in to update the .jar file for the next update. I also was now able to enable RDS for single password and could browse like the hotfix instructions advise. I've since disabled RDS and accepted the inability to browse as a "feature", happy that it's more secure as a result.
So my “problems” were largely self-inflicted due to my own ignorance of the product, but it wasn’t helped by Adobe’s apparent inability to grasp that there may be similarly ignorant people attempting these updates. It would have been nice to see some guidance from them. Furthermore, the cumulative hotfix 4 page (http://helpx.adobe.com/coldfusion/kb/cumulative-hotfix-4-coldfusion-901.html) doesn’t even mention RDS, let alone that the default behaviour changes. It’s only when you check the individual hotfix information that you can see the information that helped me to realise where I was going wrong.
As for using https not http; great, but if I’m right that my shortcut is the default out-of-the-box shortcut, where’s the information to advise to change to using https as a result of one of the hotfixes included in hotfix 4 (originally, I think, hotfix 2)? It’s certainly not mentioned on the page for cumulative hotfix 4.
