I have Hangfire installed on my web server.
And it works. And i was able to access hangfire dashboard.
But suddenly today i tried to open dashboard and when trying to access http://localhost/hangfire
i get the following error:
An unhandled exception occurred while processing the request.

Since Dashboard is some internal Hangfire tool - i just don't have an idea here how is it possible to fix the issue.
As the sql is installed by Hangfire
And Hangfire is installed from nuget.
Did anyone experienced this issue?
Any idea how to make hangfire dashboard appear?
Thank you.
Sorry.
I just realized someone renamed [Key] column in one of hangfire tables.
Is all working.

On one of Client we have Dynamics 365 CE On Premises V 9.0.4xxx.
Environment is Development, single CRM server installation having claim based authentication using ADFS. Database and Reporting Services is on another server.
We are facing some performance issues, when we investigated we found that CRM Async Service is getting crashed with the last message which says that
"The locator service failed to connect to the configuration database (MSCRM_CONFIG). The error was: System.Data.SqlClient.SqlException (0x80131904): Invalid object name 'Datacenter'."
We enabled the CRM Trace Logs and found that Asynch Service is trying to query in the database against Datacenter object which is not to be found. We investigated on many other environments and this table, view or synonym is not to be found in any of the instances. Searched on Internet and though many users faced this issue but didn't found any solution. As a last resort from our end we are in process to move to latest release of Dynamics 365 CE which is 9.1.3.11 in hope if that is a product issue, it might already solved.
If anyone have faced the same issue and/or have a solution, it would be appreciated. Thanks
Complete error msg.

I have a simple but tough problem.
I am trying to add an user to a team through user interface, however I'm getting SQL Time Out for some users.
I got no plugins firing on association request. I also did not find any familiarity between the ones I am getting this error.
I have even turned the trace log on which did not give me much more details.
Following the error log generated by tracing tool.

I recently publish my ASP.Net MVC 3 web application (Entity Framework 4.1 for Data Persistence) to a live server. The application is located on one web server and the database (SQL Server 2008) is located on another separate server.
The site has only been live a few days with very few hits, and because of this there are very few records contained within the database tables (10- 20 max).
I also have ELMAH (Error Logging Modules and Handlers for ASP.NET) integrated into the site and I have received a few instances of the following error already
System.Data.SqlClient.SqlException: Timeout expired. The timeout
period elapsed prior to completion of the operation or the server is
not responding.

The occasions where this error has happened have been due to SELECT queries. These select queries are very simple, ie,
Select col1, col2, col3 from table where col1 = 1
And as I have stated, there is very little data within the database, so it isn’t as if the queries are pulling back 100’s of records.
I have done some research into this using both the Internet and Stackoverflow. Some people suggest to increase the dbContext CommandTimeout Property, however, I don’t understand why I should need to do this. Yes, if I were pulling back loads of records, but as I have said, these are simple SELECT statements pulling back 1-5 records at the most.
I also know that developers need to keep an eye on the SQL generated by the Entity Framework, so, I downloaded and ran this trial version http://www.datawizard.com in order to get a look at the SQL being created for the Entity Framework SELECT queries that were causing a problem. Again, the profiler showed these queries to be very simple syntax, so I don’t think that is the problem.
I am beginning to think maybe it has something to do with my database and web application being on separate servers, however, I am out of ideas!
Please if anyone can help or advise me with this issue, it would be greatly appreciated.
Thanks everyone.
Step 1)
I check that i can acess server:
(because i have offline handling to)
public static bool dbOnline(string timeOut="3")
{
bool online = false;
try
{
var testConn = new SqlConnection(Utils.ConnectionStr(timeOut));
testConn.Open();
online = true;
testConn.Close();
}
catch (Exception)
{
online = false;
}
return online;
}
2) It returns ok, then i Create dlinq instance !
_DataContext = new DataContext(Utils.ConnectionStr);//System.Data.Linq.DataContext
//then i point out a customer in DB
var customer = _DataContext.Customers.TableQuery().FirstOrDefault(c => c.ID == custid);
//Check its not null
if (customer != null)
{
customer.points+= _points;
customer.LastUpdated = DateTime.Now;
customer.SubmitChanges();
}
3) And sometimes i get this error, is it anything i can do to prevent this, or is it to
fix the network? (i know there is some trouble with the network), but can i do anything
different? - Thanks

A timeout is impossible to identify in isolation, however I would usually expect a network error to have a different error. The things I'd look at first:
is the data indexed correctly
was there blocking at the time, most likely by a long-running transaction that has a lock on the data
was there anything like a db grow happening at the time
was the server exceptionally busy at the time
My money would be on the second
Also, we can't see what TableQuery() is; if that returns IEnumerable<Customer>, then it could be related to pulling too much data (in your context, it should probably be returning IQueryable<Customer> at the minumum, but we can't see).
The real thing to do here is to run a SQL trace and try to catch it in the act - see what was happening.
I am using Linq against a DBML file, I believe this is Linq2SQL.
During development, I used a staging database called "Stage", and am now using a different database. My rights to the staging database have been removed.
When I use the following connection string
<add name="Management_Report_Emailer.Properties.Settings.DWConnectionString"
connectionString="Data Source=biqasql01;Initial Catalog=DW;Integrated Security=True"
providerName="System.Data.SqlClient" />
</connectionStrings>
and then pass that inner string to Linq
DWDataContext DWctx = new DWDataContext(CurrentServerConnection);
Some of my linq queries work, some dont. The one that doesn't work throws this exception
Error The server principal "mydomain\myusername" is not able to access the

QUESTION
Why the heck is it trying to access the wrong database "DWStage" ??? I've reduced this to only four lines of code in this application, none of them reference that string. I did a file search for that string and can't find it anywhere.
The correct answer is : Check your view!
I'm using a table in a different database in the referenced view, that my account doesn't have access to. SQL is correctly reporting that I can't view that other table.
