Reload failed- log shows General network error

deepti_singh — Tue, 30 Jun 2015 22:52:36 GMT

Hi,

I have a QVD that reloads everyday. It pulls data from ONLY one view which has 26,814,603 rows, using a simple select statement. The QVD ran successfully for many days and then suddenly failed to reload yesterday. The log shows the error "Error: ErrorSource: Microsoft OLE DB Provider for SQL Server, ErrorMsg: [DBNETLIB][ConnectionRead (recv()).]General network error. Check your network documentation."

I looked online and found that it may be due to generic timeout error.

My question is- this QVD failed to reload recently and was running successfully since it was created that is 6 months back. Why did it suddenly fail to reload and how can I overcome this error?

Thanks.

Deepti

Hi Deepti

Maybe at the time you reload you have some conection problem, could be that have lost the connection with the view, or some other conection problem like the user and password to connect to the database could change.

after that you continue with the problem?

hope help, Fernando

Hi Fernando,

The view has 26 million rows, so it must have lost connection with the database. I know for sure that he username and password didn't change- because that would cause all other dashboards to also fail, but they didn't.

The QVD didn't fail to reload today. So I am assuming it is just that there was too much load.

Can you tell me how I can improve the performance of such a large QVD?

Thanks.
