CF8 Standard Hangs
Recently upgraded to CF8 on 6 of our servers. Our software
vendor recommended we go with coldfusion standard edition. We have
550 concurrent connections, with the users browsing pages and
generating PDF Quotes. Every couple of days coldfusion locks up and
we have to restart the Coldfusion server. I have to report to my
boss if upgrading to enterprise will correct the problem. Only the
18k we are going to spend in upgrading doesn't warrant any help
from Adobe they want me to pay $400.00 so an engineer can tell me
we need to spend another 18k. So I'm hoping someone else has
experienced a similar problem, or can point me in the right
direction where I can prove to my boss that the single threading of
CF8 cfdocument tag is causing the server to lock up.
Since standard does not have the built in monitor, one or
both of the
third party tools, (SeeFusion and FusionReactor) provide
great
monitoring features that can point out bottle necks and poor
preforming
code. They would show the threads piling up behind this
single thread
point, if that is what is happening.
They both have trials as well as very low costs so that would
be my
first sugestion.

CF8 Standard w/Apache Guidelines?
Web Server: Apache 2.2
CPU(s): Intel(R) Xeon(R) CPU, 5160 @ 3.00GHz, 2 core
Memory: 4G
Operating System: SUSE Linux Enterprise Server 10 (i586), VERSION = 10, PATCHLEVEL = 2

For 99% percent of the time we have a pretty light load with 1500 hits a day mostly info pieces and some light e-commerce to register for classes. On registration days we get annihilated jumping from 100 connections to 800 right when we open.
We have used jmeter to try and gauge exactly what our one server is capable of handling. And I guess we still really do not know. I have noticed that if we sustain anything over 700 apache connects JRUN will throw errors. This seems to be by a design limit and happens automatically regardless of the pages involved. We have used seefusion to make sure none of our pages are hanging the server. Nothing is excessive though very little bit helps.
Can anyone suggest some general guidelines as to how many apache connections we should allow and what cf8 standard should be able to handle. The registration process is db intensive requiring many calls per page to maintain session etc. We have to do this to maintain compatibility with our internal system.

Is it possible to accommodate 1,000 users with ColdFusion 8 standard? Yes it is possible, if the application is developed with this load in mind. Will CF8 magically accommodate 1,000 users no matter what, NO! No application server could.
Unfortunately there is no general answer, because EVERY application and server is different. Why do yo have to have so many database calls? What can you do to unload that to the database with procedures and packages? What can you do to cache content? What can be streamlined? What can be trimmed? What can be reused?
None of those answers are magic or automatic! The system and application have to be looked at systematically and anaylized and tuned. -
Install cf8 standard edition with remote apache?
I am interested in installing cf8 standard edition on a stand
alone server on a windows (win2003 standard 64 bit) box. An Apache
web server (centOS 5) and a mysql will be another two separate
servers.
So, I am wondering if this infrastructure is OK? I never
tried them like this. I'd appreciate if anybody may share practical
experience. Thanks.Have you had any luck with this? I'm pursuing a similar
configuration. It should be pretty straight forward since this is a
pretty normal set up, but the doc is limited.
It doesn't help that the connector for Apache seems to be
buried in the Linux install, which doesn't help when CF server was
installed on a Windows box. Am I missing something? -

CF8 Standard on Linux 64bit?
Hi all,
I tried to install CF8 64bit on a 64bit Linux machine and it automatically got reverted to a developer version as our license key is for a standard version and not for an enterprise version, ok so far so good. I went back and installed the 32bit version on the machine and entered the code, seems to work fine BUT: I have CF running behind an Apache web server and I configured the Apache connector to be able to access the CF Admin via a regular URL, eg. http://dev.company.com/CFIDE/administrator instead using the port (eg. http://dev.company.com:8500/CFIDE/administrator) on which CF is running. CF told me, that it won't work with an Apache 64bit. I must say I'm little bit confused. Some questions on that:
- Is it correct, I need an enterprise license to run CF8 64bit?
- Can I install and run my standard license somehow on the 64bit machine?
- Does CF9 help me in this case by being 64bit capable in the standard edition?
- Or at least can I install CF9 in a 64bit environment?
Thank you very much for any advice, cheers

Moving CF8 Standard Server License
Hi all,
I'm really nervous about this, because this is a production server. I'm wanting to know if there are problems or issues that I should be aware of.
Current Server:
Windows 2003 Standard 32-bit
Coldfusion 8.01 32-bit standard
1 or 2 proc license
New Server (presently running in 30 day trial mode)
Windows 2008 R2 SP1 64 bit Standard
Coldfusion 8.01 32-bit standard
1 or 2 proc license
Everything is working on the new server, sites are operating normally.
Is it really as simple as?
- copying the text string license number
- stopping CF8 on the old server
- pasting the text string license number inside CF Admin on the new server
- restarting CF8 on the new server
What am I missing? Will this same license work on 32-bit CF8 in a 64 bit environment (Windows)?
TIA,
MarkNope, it's even easier than that - put the key into the new server now and it'll just work. Only thing you'll get is the occasional info message in the server.log saying "oh hello, someone on the network is using my key", at which point you just carry on with your life.
Not even any need to restart CF8 I don't think, CFAdmin will just apply it for you. I used our key on countless servers once when I was playing around with different versions of Windows for our devserver, nothing will shut down, Adobe will not come knocking at your door. If it's a genuine swapover and you have enough licences for the servers you're using, I'd sleep well at night. -
Windows 2008 standard hangs during chkdsk
I have a file share server running windows 2008 standard edition. It is connected to a SAN via Fiber channel. There are 4 volumes presented to the Server via the SAN. After a critical error occured, I restarted the server and the OS requested
that I run chkdsk on the SAN volumes. I allowed it to run. It quickly got to the indexs, but then got hung at about 49% in stage 2. After letting it set for several hours, I was forced to hard boot. Upon restart, I did not allow the
chkdsk to run as this is a production server. The server booted up with no issues and all of the data was intact. I recently migrated the data via Thin Import to a new SAN. All of my data now resides on a brand new set of discs in my compellent
array. To save down time, I presented the volumes to the server using the same drive letters. The server immediatly asks to run chkdsk on these volumes. I run chkdsk and it still hangs in the same spot on the indexes. I've made snapshots
of the volumes and presented those to another server. After running a rescan in disk managment, that server requests a scan and fix. I let that run and it completes. I'm at a loss on how to correct this issue. The data seems fine, but
chkdsk will not complete.Hi,
Stage 2: Chkdsk checks the directories in the volume. Based on your description, please use
chkdsk /x command to force the volume to dismount. Then check if you can execute the process of chkdsk successfully.
Meanwhile, please go to Event Viewer and check if you can find some related errors.
Hope this helps.
Best regards,

Difference btw cf8 standard and enterprise
hi,
i've downloaded the pdf from adobe website stating the
difference btw standard and enterprise edition. But i'm quite
puzzled on this:
Enterprise feature that runs through the Enterprise Feature
Router (EFR). These features will run in the Standard
Edition. However, all features running through the EFR will
be limited to one shared simultaneous request.
What is EFR? And does it mean that for standard edition, all
the tags fucntion remains the same except that it only allow 1
request of such tag at 1 time?"What is EFR? And does it mean that for standard edition, all
the tags
fucntion remains the same except that it only allow 1 request
of such
tag at 1 time?"
For the effected functionality. This does not apply to all
Standard
Functions, just new Standard Functions that previously where
Enterprise
only such as gateways. Standard not has gateways, but only
one at a
time. I believe the same applies to some of the advanced PDF
functionality and similar features. -

FileNotFound exception when trying to overwrite or delete an image in CF8. Why?
I have CF8 Standard Edition installed in my server and when I try to use CFIMAGE to overwrite the uploaded file with a resized one, or to write an image previously resized with ImageResize or ImageScaleToFit, I get an internal server error caused by a java.io.FileNotFoundException with some images, many in fact. In other words, the error happens because the system cannot find the file to overwrite.
Apparently the process jrun.exe maintains the original image blocked in such a way that even rejects a file name change. I used the same CF version in an older server and everything run smoothly, but when I had to change the server and migrate my websites I found this problem. The server is IIS7 on a Windows Server 2008 OS. Of couse any CMS without a proper image management is unuseful, so that is a critical issue for me.
Can somebody help me?I have read the thread http://forums.adobe.com/message/844356#844356 and saw that the problem I had is due to a bug. Then ksmith posted: Try Patch for CFImage and Image functions in ColdFusion 8.0.1 (kb403411). And the patch works! wonderful! Problem solved!
Thank you very much for your fix. -
Standard vs Enterprise different?
I'm trying to find out how to calculate the maximum
connection/capability of a server in real life.
Let's say, I've a dual xeon with 4GB ram + HD RAID5 or SAS...
WIN or LINUX + CF8 32 or 64 Bit.
For your experience, in a company that has connection around
50 users. Is this enough for that hardware + CF8 Standard Edition?
Then when I should consider Enterprise version? One of my
customer has ~200 users, should I change hardware + version of CF?
The application is based on Flex + CF. Not much PDF
generation. Usually use Transfer-ORM, ColdSpring, + PostgreSQL
backend.
I've this problem because I don't have enough experience for
CF server. Please someone, guide me how to choose between Standard
& Enterprise version.jedt3d wrote:

I have seldom seen throughput or number of users as reasons
to choose
between standard and enterprise. They both will handle
considerable
load and numbers like 50 and 200 should be a drop in the
bucket for each
server depending on what type of heavy load tasks they may be
expected
to carry out.
I.E. a heavy processing application used by 10 users could
bring a
enterprise server to it's knees while a standard server could
easily
handle 10's of thousands of users on a well thought out and
properly
scaled application.
Factors you probably want to consider are features. Standard,
at this
time, is only 32 bit. So if you want to make use of 64 bit
hardware you
probably want to consider enterprise.
Enterprise allows multi-home and J2EE configurations.
Multi-home allows
for single box application isolation and roll over effects as
well as
the ability to make use of more memory then a single JVM can
access. A
bit under 2GB for a 32 bit installation. J2EE configuration
allows you
to use other Java Servers then the built-in JRun4.
Enterprise as more throughput for some tasks such as e-mail,
gateways
and such. Some of these features are single threaded on
standard while
they make full use of multi-thread capabilities in the
enterprise version.
My gut instinct from your original post is that Standard
would probably
be enough for you. But if you want to speak to somebody in
Adobe you
could provide real answers try one of these contacts.

Hi,
I have to upgrade an existing production server from CF7
Standard Edition to CF8 Standard Edition and have not found any
upgrade instructions specific to this version. I am running this on
a Win2003 Server using IIS as the web server.
Is it as simple as downloading the latest build of CF8,
installing as a standard edition and supply my upgrade Serial
Number?

Hi
I'm doing an upgrade from GW2012 sp1 to gw2014
We also have Datasync 1.2.5
GW2014 says update to GMS 2.0 before upgrading to gw 2014
GMS 2.0 requires GW2012 sp2
Do I need to update GW2012 sp1 to GW2012 SP2 (as GMS2.0 reqiures) before
I can upgrade to GW2014
or;
Can I stay on GW2012 sp1, upgrade to GMS2.0 and after that to GW2014
skipping the GW2012 SP2 step ?
/mats
I doubt you will run to any issues if you don't upgrade to 2012SP2.. Will you run GMS 2.0.1 for a long time against 2012 before upgrading to 2014SP1?

Enabling Windows Performance Monitor in CF8
Platform: Windows 2003 SP2, CF8 Standard (upgraded from CF7)
I can't seem to get the Windows Performance Monitor Counters
for CF8 to work in my newly upgraded installation.
1) In CF Administrator > Debug Output Settings I tick the
"Enable Peformance Monitoring" option and click Submit Changes.
Message: "Server updated" appears and the box remains ticked.
However If I refresh the page or navigate to another and return,
the tick is lost.
2) Restart CF Service
3) Open Perfmon and click Add Counters
4) ColdFusion 8 Perfomance Object and Counters are all listed
correctly, BUT there are "no instances" in the box on the right and
therefore the "Add" button is disabled, so I can't add any
counters.
5) Checking in CFAdmin again, the "Enable PM" tick is still
lost.
It all worked in CF7, however that was on W2K3 SP1.
SP2 is a new factor, could that be the cause?
Thanks.Fixed by editing the neo-metric.xml
