Application Cannot Communicate With DB
Sep 24, 2007
I have a C# windows application which i've developed that uses an embedded SQL CE DB.
When i deployed the project, It worked fine for many PCs.
But for some PCs it seems it cannot (The application) communicate with the DB.
Why i am saying that ? That's because the application itself opens . but at the first task where the applciation requests the DB for information, It just CAN'T do that, And stands as if no action has happened (i.e. no button has been pressed)...
Any ideas ?

So SQLDependencies failed to do what I wanted them to do for my Cache Invalidating, so i'm going to humor another possibility for a half day - Triggers on my database table that communicate messages to my C# inside my ASP.NET App. Any advice on how to tap into a message queue with C#? I'm thinking that my messages could be 1 of about 100 different strings as far as what occurred on the Database Tables

Hi,
Just need some help on a job issue.
The job in question gives the below mentioned error when run
Error 22022: Unable to post notification to SQL
ServerAgent (reason: OpenFileMapping()returned error
2, 'The system cannot find the file specified')
This seems to have started after I changed the owner for the Agent and MSSQL service from local service to a domain ID.
FYI, I have also changed the job owner from sa to the domain ID and have tried restarting the agent service in the hope that the Job can speak to the agent .. but it doesnt :(
Microsoft suggests to change some registry entries but I am not sure if that'd work
http://support.microsoft.com/default.aspx?scid=kb;en-us;911841&sd=rss&spid=2852
The server on which this job is hosted is a production box .. so am a litle apprehensive about making any registry changes
Any Suggestions ?
Thanks.
Warm Regards,
Ranjit.

When I browse to http://localhost/Reports/Pages/Folder.aspx I am getting "Unable to communicate with report server. Please verify that the report server is operational". The http://localhost/ReportServer runs fine in the browser. Also the config files have the correct urls. I don't have any other service like Sharepoint installed on the machine
Any ideas?
Thanks

-> Communicate with WebService from MS SQL 2005 CLR Procedure, Quick Steps
1- Create SQL project in V.S 2005.
2- Add new Trigger Class, right click on project select Add -> New Item.
3- Add Web Service reference.
4- Use impersonation technique to communicate with Service.
Example:
using (WindowsIdentity id = SqlContext.WindowsIdentity)
{
WindowsImpersonationContext context = id.Impersonate();
/////////////////////////////
proxy = new WebServiceProxy();
proxy.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials;
proxy.HelloWorld();
/////////////////////////////
context.Undo();
}
5- Set SQL Project Permission Level to External, change from the project properties Database Tab
"Permission Level Select the permission level from the drop-down list to specify a set of code
access permissions granted to the assembly when accessed by Microsoft SQL Server. The value can be
Safe, External, or Unsafe; these values correspond to the SQL Server permission sets SAFE,
EXTERNAL_ACCESS, and UNSAFE, respectively. Safe is the default.
This setting corresponds to the PERMISSION_SET argument for the SQL Server CREATE ASSEMBLY command.
" MSDN
6- "The TRUSTWORTHY database property is used to indicate whether the instance of SQL Server trusts
the database and the contents within it. By default, this setting is OFF, but can be set to ON by
using the ALTER DATABASE statement.
Note:
To set this option, you must be a member of the sysadmin fixed server role." MSDN
ALTER DATABASE [Database Name] SET TRUSTWORTHY ON
.
7- Build and Deploy assembly.
8- The web service reference generates XmlSerializers assembly, there are many ways to resolve
this issue, a quick way would be to add the XmlSerializers assembly to the database where the
main CLR assembly is deployed.
From "SQL Server Management Studio" select the target database, goto "Programmability" then ->
"Assemblies", there right click "New Assembly" and specify reference.
Hope this is helpful to others.

Hello,
I've enabled full-text indexing on one of my tables, and the following query used to work:
SELECT *
FROM TempAttachment
WHERE CONTAINS(attachment, 'text')
However, now I get the following error:
Msg 9955, Level 16, State 1, Line 1
SQL server failed to communicate with Full-Text Service (msftesql). The system administrator must make sure that same service account is used for both services and the service account has the permission to auto start the full-text service.
I've checked the configuration and verified that both accounts are the same. I've restarted the services, and tried rebooting, and still no luck. I did a search on this error, and found this page from MSDN, which doesn't help me much: http://msdn2.microsoft.com/en-us/library/aa337365.aspx.
Has anybody come across this before? Any help would be greatly appreciated!

I am getting the following warning for my SSIS08 package: Could not open global shared memory to communicate with performance DLL; data flow performance counters are not available. To resolve, run this package as an administrator, or on the system's console. I did check Warning in SSIS 2008 , but didn't find any solution. The package processes data and executes fine , but why do I see this warning? When I run this package on my machine, I see no such warning, it's only when I deploy it to our DEV SSIS server, I get this warning.

Hi
I have created a Visual Basic application the connects to my SQL database.
The appliction lets a user click on a button, data is retrieved from the database
and then formatted in Excel. Everything works fine on my machine (this is probably
because i have both VB and SQL installed on my machine)
I have created a .exe and deployed the application on some users desktops. The
problem is that when they click on a button - nothing happens. I dont even get any
error messages! Everything else appears to be fine. I have tested the DSNs and
they appear to be fine too.
Does anyone know why this would happen ??
Thanks, Ruaidhri.

Whenever a user logs on to SQL-Server there´s
a message in the application log of windows NT
like
"Login succeeded for user 'Domainusername'. Connection: Trusted."
Since we have lots of users. The application log fills up twice a day.
Is there any way to prevent SQL-Server from doing this ?
(I know that there are settings in the event-viewer which clear events
whenever space is needed).
Thanks.

I'm not sure if this is the right section for the question, but here goes...
I have an application that needs to be run in network client mode. This app is supposed to connect to a SQL 2005 db hosted on a server. As I procede through the installation process I get a prompt when i populate the serverdb information.
'The listener port was responsice, but did not return a primary port number for <servername>. Please verify that <servername> is a valid and running database before proceeding.
A little background is in order:
Host:
Server 2003 Standard
SQL Server 2005
Installed instance of said db
Client:
Windows XP Pro sp2
Network config:
We have a domain with about 125 workstationslaptops. Windows firewall is turned off using a group policy (makes it easier to push apps out to clients). For giggles I made exceptions to the 'turned off' firewall policies for the needed ports etc. This was done on both the host server and the client.
Thank you in advance.
