I am using Coldfusion MX8 server and one of the scheduled task was running from 2 years but now suddenly from 01/12/2014 scheduled tasks are not running. When i browsed the file in browser then the file is running successfully without error.
I am not sure is there any updatation or license expiration problem. I am aware that mid of this year Adobe closed the support for coldfusion 8.
The first most common problem of this problem is external to the server. When you say you browsed to the file and it worked in a browser, it is very important to know if that test was performed on the server desktop. Knowing that you can browse to the file from your desktop or laptop is of small value.
The most common source of issues like this is a change in the DNS or network stack that is interfereing with resolution. For example, if the internal DNS serving your DMZ suddenly starts serving the "external" address - suddenly your server can't browse to your domain. Or if the IP served by the server for the domain in question goes from being 127.0.0.1 to some other IP that the server can't acces correctly due to reverse proxy or LB or some other rule. Finally, sometimes the Apache or IIS is altered so that an IP that previously was serviced (127.0.0.1 being the most common example) now does not respond.
If it is something intrinsic to the scheduler service then Frank's advice is pretty good - especially look for "proxy schduler" entries in the log - they can give you good clues. I would also log results of a scheduled task to a file. Then check the file. If it exists then your scheduled tasks ARE running - they are just not succeeding. Good luck!
I've seen the cf scheduling service crash in CF8. The rest of CF is unaffected.
Have you tried restarting the server?
Here are your concerns:
Your File (works since you tested it manually).
Your Scheduled Task (failed).
Your Coldfusion Application (Service) (any changes here)?
Your Server (what about here).
To test your problem create a duplicate task and schedule it. Leave the other one in place (maybe set your new one to run earlier). Use the same file too. See if it completes.
If it doesn't then you have a larger problem. Since the Coldfusion Server sits atop of the JVM there could be something happening there. Things just don't stop working unless something got corrupted or you got compromised. If you hardened your server by rearranging/renaming the file structure to make it more secure...It would break your task.
So going back: if your test schedule works then determine what is different between the two. Note you have logging capabilities. Logging abilities for CF8
If you are not directly incharge of maintaining this server, then I would recommend asking around and see if there was recent maintenance, if so, what was done to the server?

I had installed ColdFusion 2018 recently and with the installation less than a month old (and my understanding of the technology even less), my Cold Fusion service has stopped working. I have tried a number of things and have referred to a number of articles and out of many such errors where the service is not being accessible, some of them were able to get it resolved. However, some other obscure reason that may be causing this error have been untouched and unknown.
Whenever, I try to restart the service, I get an error as shown below:
Windows could not start the ColdFusion 8 Application Server on Local Computer. For more information, review the System Event Log. If this is a non-Microsoft service, contact the service vendor, and refer to server-specific code error 2.”
Without much understanding, I started to google it out. Looking into every one of these posts, I tried
Configure JRE and try to relaunch the service by looking at "JAVA_HOME" variable and JVM.config
Run the batch files in every possible combination to find if anything clicks
Check if the present JAVA version works and is compatible with Coldfusion version installed
Fiddling with the "SessionStorage" var in neo-runtime.xml file as some suggested
and few other tricks coupled with a numerous service restart attempts and a few machine reboots as well.
A service that renders Cold Fusion pages should be shut down abruptly. To add to agony, the CF Admin also depends on the service and hence does not work.
Any pointers to any potential solutions?
I am currently using Jetty 9.1.4 on Windows.
When I deploy the war file without hot deployment config, and then restart the Jetty service. During that 5-10 seconds starting process, all client connections to my Jetty server are waiting for the server to finish loading. Then clients will be able to view the contents.
Now with hot deployment config on, the default Jetty 404 error page shows within that 5-10 second loading interval.
Is there anyway I can make the hot deployment has the same behavior as the complete restart - clients connections will wait instead seeing the 404 error page ?
Unfortunately this does not seem to be possible currently after talking with the Jetty developers on IRC #jetty.
One solution I will try to use are two Jetty instances with a loadbalancing reverse proxy (e.g. nginx) before them and taking one instance down for deployment.
Of course this will instantly lead to new requirements (session persistence/sharing) which need to be handled. So in conclusion: much work to do in the Java world for zero downtime on deployments.
Edit: I will try this, seems like a simple enough solution http://rafaelsteil.com/zero-downtime-deploy-script-for-jetty/ Github: https://github.com/rafaelsteil/jetty-zero-downtime-deploy
I have an Apache2 and Django (mod_wsgi) setup that provides a RESTful API. I have a set of automated tests for this, that executes ~1000 API requests (pure http GET/POST/PUT/DELETE) in sequential order.
The problem is, for every 80 requests or so, I get a strange lag/timeout for exactly 5s or 10s. See timestamp examples here:
Request 1: 2013-08-30T03:49:20.915
Response 1: 2013-08-30T03:49:30.940
Request 2: 2013-08-30T03:50:32.559
Response 2: 2013-08-30T03:50:37.597
I can't figure out why this happens. I have an apache config with KeepAlive Off (recommended setup setting for Django) but otherwise standard install for Ubuntu 12.04 LTS.
I'm running the tests from the same server where the webserver is, I first thought this was some kind of DNS cache thing, but I've added the hostname I'm requesting to /etc/hosts but the problem persists.
The system is idle and have lots of cpu and mem when this lag/timeouts happens.
The lag is not specific to a certain request (URL), it seems kinda random.
Considering that it's always exactly to the millisecond 5s or 10s, it feels like this is some specific setting somewhere causing this.
In case it provides some insight, watch my talk from PyCon US.
http://lanyrd.com/2013/pycon/scdyzk/
The talk deals with things like process churn and startup costs. One thing you shouldn't do is set maximum requests if you don't really need it.
Also consider trying New Relic to help diagnose where the issue is. That will save a lot of guessing if it is a web application of backend service infrastructure issue.
As far as seeing how such monitoring can help, watch another one of my PyCon talks.

This was a DNS issue, adding the domainname I used locally to /etc/hosts actually solved the problem. I just hadn't reboot the server for the changes to take effect, thought restarting networking would take care of that, but apparently not.

How to restart Coldfusion Application Server when application is timeout?
Currently I have an ColdFusion application that causes server issues. After 1-2 days that serve doesn't respond until a manual restart is done.
I know that I had to find what is going wrong in my scripts and I spend time and time for several weeks.
But pending I would make a script that restart automatically ColdFusion service if it is bugged.
I have not many knowledge in batch script etc.. but I guess that the test would be a request to a .cfm and the response would be serve until a timeout. ?
Has anyone ever met a script like this ?
Config: Win 2k8 Server R2 - Coldfusion 9(.0.0)
Thank you
Two things here
The real way is to fix the issue and you can do that with Fusion Reactor - http://www.fusion-reactor.com/fr/ It will help you monitor and restart and self heal as it needs.
You could create a batch file, and create a Scheduled Task in Windows that ran it.
Using Net Start / Net Stop Commands
net stop "Macromedia JRun CFusion Server"
net start "Macromedia JRun CFusion Server"
Thought this may not always work so I have a batch file:
c:\JRun4\uninstall\KillJRun.exe
net start "Macromedia JRun CFusion Server"
Which works for me.
Your best bet is to use Pingdom or another server monitoring tool. When the server goes down (responds with a 503 error, service unavailable) you may be able to have Pingdom send a response to a PHP script on the server that calls a batch file. I am not sure if Pingdom supports pinging another server is one is down, but you could have Pingdom email to an inbox that your PHP can check every few minutes.
This may end up being more work than figuring out what is wrong with your script though.
Edit: You may want to look at this question. This will only work if the service has stopped, whereas usually when a script crashes ColdFusion it is hanging. If you run the script that crashes the server, then look at the service, if it says stopped, then this may work for you.
The other thing that I would check is the JVM memory. Often times crashes are due to processing large amounts of data from files or the database and the JVM doesn't have the memory to do that.
Nope. It cannot be restart automatically when your CF services/server is hanging. The only one way is to restart by windows schedule.
You could also use Nagios+Plugins to fire a restart script when the service hangs. But following the previous advice & finding out what the problem is is your best bet.
Afternoon all,
We have a group of four BizTalk servers: two orchestration hosts and two adapter hosts. We have a number of orchestrations exposed as web services, and for the purposes of this question, it is important to note that these web services are hosted on the adapter servers, and run under the BizTalkServerIsolatedHost host instance.
This morning, we started seeing odd errors on both of the adapter servers when SOAP calls came into the web services, like this:
The Messaging Engine failed to
register the adapter for “SOAP” for
the receive location blahblahblah.
Please verify that the receive
location exists, and that the isolated
adapter runs under an account that has
access to the BizTalk databases.
We restarted IIS on both servers, which fixed the errors on ONE server, but the other server continued to fail. The errors continued after a reboot as well.
After chasing our tails for a while, we eventually discovered that the BizTalkServerIsolatedHost host instance on the still-failing server was gone. Just... gone. These applications have been in production for months. Everything had been working swimmingly through the morning, until this just happened.
I don't want to muddy the waters, because I think the problems are unrelated, but in the interest of providing enough information, this problem exactly coincided with a problem in our load-balancing network hardware. The load balancer, which provides a single URL to consumers, and round-robins between the two adapter servers, just stopped working. This problem has not been resolved, so I don't know what happened, but it certainly made troubleshooting more interesting...
So, I have two questions:
Has anyone seen this before, where a host instance disappears?
We cannot find anything in the event viewer or anywhere else that says the host instance was deleted. Is this logged somewhere?
Thanks,
Jason
