I had to change my web application on cfwheels-1.1.8 to a UNIX server with ColdFusion-10.
Now cfwheels can't find the specified data source (mysql-5) in config/settings.cfm.
The error message is: Wheels.DataSourceNotFound - The data source could not be reached. Suggested action - Make sure your database is reachable and that your data source settings are correct. You either need to setup a data source with the name db_source in the CFML Administrator or tell Wheels to use a different data source in config/settings.cfm
It worked fine on ColdFusion-9 and Windows Server 2003. I heard that this may have something to do with case sensitivity. I tried some different cases but that didn't solve the problem.
Does anyone have any ideas or know of a solution?

I have a web application which I developed which uses crystal reports for VS 2010. The reports work fine on my machine, but when I publish the web application, I get the following error when loading the report:
Error
This group section cannot be printed because its condition field is nonexistent or invalid. Format the section to choose another condition field. Error in File temp_9b46c401-8cdb-45a6-bade-4d3e37dda1fb {572D2B99-425A-4EC5-A758-6497001368A3}.rpt: Invalid group condition.
I've searched for this and from what I can understand it's a connection issue. But I've checked and the database connection string is fine. Other parts of web application work fine with it. Is there anything else I should be checking for?
I've resolved the issue. It was very frustrating and so I thought I should put this here in case anyone runs into this:
Make sure you have the same version of Crystal Reports Runtime installed on your server as on your development machine. I had 13.0.3 on my development machine and 13.0.1. on my server. Of course crystal reports gave an obscure error which makes it very difficult to know where to look.
After I did this, I kept getting a blank page. This linked help me resolve this issue: http://www.codeproject.com/Questions/287543/Crystal-Reports-not-rendering-when-webpage-is-serv. Apparently visual studio doesn't copy all the necessary files for it to render the reports.
Thanks.
I'm not so sure that the error is because of a database connection issue. If I were you I would look into a few things first:
Make sure that the database fields haven't changed. Is the application accessing the same database when deployed as it does in the development environment?
What about Null values? Have you checked the "Convert Database Null Values" in the Report Options?
What about the groups? Are there any formulas in them or are any of them based on groups? Browse the data to see if you get any errors.
Just because it runs on your development machine doesn't mean the problem isn't in the datasource. Maybe one of your report's formulas is expecting a field to be non-null, and there is a single null entry. Or a date somehow got entered as #01/01/9999# and a formula in the report is expecting a realistic date.
That should get you started and maybe even solve your issue. Give us some more info about the report and the datasource if you can.
I have been given an ad hoc reporting tool from another individual that has successfully deployed it to the field. He uses Web Logic servers and an Oracle database.
I tried to deploy the same application in my local environment (WAS 7 and Oracle). The first report runs flawlessly. However, when I run the second (or third or fourth) report, I get a very strange error: the second report is appended to the first report.
There is nothing in the code to account for this. This problem can be temporarily solved by stopping and starting the servers every time a report is run (obviously not a real solution). I think this has something to do with data sources and cached information. I then took a step back and tried to deploy it to a Tomcat server. It works perfectly, just like it does in the field. So my question is: are there any known issues between WAS 7 and Oracle 11g that could be causing this kind of problem? Any information would be very helpful.
Please ask about any specifics you may want to know and I will do my best to provide that information.
Thank you for your time.
EDIT: For anyone else looking into this, the problem was due to an incompatibility with the proprietary Oracle calls and Websphere. Once the application was edited to use only JDBC calls, everything works perfectly. Thanks.
This ended up being a incompatibility with using proprietary Oracle calls and Websphere. It was fixed by changing all of proprietary call to normal JDBC calls.
In order to help out one of our departments here I've cloned a machine that was on its last legs and is actually hosting some important data. The plan is to migrate to a VMware VM as soon as possible, but in the meantime I cloned the machine onto another PC for testing among other things.
I've renamed the original machine's hostname,
so the new machine is running ASP.NET and SQL Server 2005 (Express)
and the database-driven website (Intranet-only) is now back up and running but we're getting an error 4200 with ODBC about a login failed.
On checking the event viewer there's the following message:
However it seems that SQL server still sees the local accounts as being under a much older hostname (see below:)
If I try to add the user "CURRENTHOSTNAME\ASPNET" to the database in question it only sees the old hostname. Is this what's causing my problem ? I'm not sure.
I do know that to get IIS working in the first place I had to do "aspnet_reg.exe -ga CURRENTHOSTNAME\ASPNET" and that fixed my first problem but this second one has me stumped.
The third party company that supply the software are being very slow to help on this. I usually do PHP & MySQL so I've little to no knowledge of Microsoft SQL. If anybody can help me you'd really be saving my bacon as this is dragging on a couple of days now.
Thanks in advance!
Renaming a machine with a SQL server instance on it can be tricky. My guess is that you get the old machine name when you run this query:
SELECT ##SERVERNAME
If you do, the old computer name is still stored in the sys.servers table. You might be able to simply follow Microsoft's instructions at renaming, which is just running a couple of stored procedures:
sp_dropserver 'old_host_name'
GO
sp_addserver 'new_host_name', local
GO
By cloning a machine you're opening a big can of worms. My suggestion would be to backup data only and restore it to new computer with fresh installs of everything. But in your case, there are two things that I'd try:
after cloning you must reset SID - check this link
sql recognises users by their id/guid, so delete all users from sql server/database and add them from scratch
Okay it seems to be fixed now - I re-added the NEWHOSTNAME\ASPNET to Security\Logins under "Microsoft SQL Server Management Studio Express" and then it appeared under Databases\MyDatabase\Security\Users" or I was able to add it anyway (can't remember which) - not sure if renaming the server that shows up under SELECT ##SERVERNAME makes a difference, but this error is fixed now anyway
Sorry about the mishmash of words in the title, but that's how confused I am. I can't even summarize the error I'm getting in a simple sentence.
This flex/amfphp application works fine on my computer, even though it accesses an Oracle database on another server. However, when I try to access it from another computer, this is the error I get. I'll try and put the most relevant code in. (My browser tell me this is an ActionScript error).
Fault faultString="Send failed"
faultCode="Client.Error.MessageSend"
faultDetail="Channel.Security.Error error Error #2048: Security Area Violation..
Couldn't load data from http://localhost/.../amfphp/gateway.php
As I said before, it works on my machine for some reason. Now, when I try to access this remotely from other machines, it seems that the PHP engine is looking for gateway.php on the localhost of that machine?? Does this mean that PHP is looking for gateway.php on the client's localhost rather than on the server??
Correct me if I'm wrong, and thanks in advance
Your services-config.xml in Flex propably points to http://localhost/.../amfphp/gateway.php
You'll need to change the endpoint in that XML file and recompile the application.
You could also create your ChannelSet at runtime. In that case you don't need the services-config.xml anymore. Take a look at http://raghuonflex.wordpress.com/2008/06/05/endpointatruntime/ for some inspiration...
I've promised to take a look at an old DotNetNuke installation for a client with the intention of making a few, hopefully minor, changes. The installation is rather old - I believe version 3.0.013 - and the production copy is running against SQL Server 2000, Windows 2003 and .Net 1.1.
As the production server is live and significantly used we need a development installation first. I have attempted to install a copy on my local server - Windows 2003, SQL Server 2005, .Net 2.0, and although with a few tweaks I can successfully get it to display the site, I cannot login, or even access the login module (ie just putting in blank username and password attempting to generate a 'must enter username' type error) without getting the error 'Object reference not set to an instance of an object'
I've spent some time trying to get around this error, without success, although I am hampered by not having used this package before.
So my questions are
Has anyone managed to run DotNetNuke 3.0.x with this configuration (or do I need to setup a box with SQL 2000 and .Net 1.0 to get it to run)?
Any suggestions where I should start looking for this error, or has anyone come across anything similar before?
EDIT: Eventually chickened out and installed in on an old webserver with Win2003/SQL 2000/Net 1.1 and it went in fine on an identical install. So I guess the answer is no, it doesn't work straight out of the box.
My feeling is that you shouldn't have any trouble running in the above mentioned environment. But taking a closer look at the error itself will help us to prove that.
If the error is occurring only when you navigate to the Login module, it may be an issue loading the authentication provider. The best way to find out is to look in the DNN Event Log and take a look at the full error message.
Because you can't login to access the Event Log, you should probably just take a look at the row created in the database when you receive the error. The table is called EventLog and there may be a little bit of friction in parsing the error message out, as all of the details are stored in the database in an XML format.
In general, when moving a site from one environment to another there are only a couple of things that you'd need to do:
make sure you can connect to the database
set the file system permissions
It sounds like you already have database connectivity because you can load the site.
However, you may want to double check (just re-apply) the file system permissions for the root of the website on the machine in question. Make sure the identity of the website (typically ASP.NET Machine Account or Network Service) has 'Modify' permissions on the root website directory. Perhaps the web site can't load a particular assembly due to lack of permissions.
