As per the Microsoft documentation
In these circumstances, SQL Azure will close an already established connection:
An idle connection was held by an application for more than 30 minutes.
You went to lunch and left your SQL Server Management Studio connection for longer than 30 minutes
Is there any way to increase the above mentioned duration to 2 hours?

I have this program that uses QLOLEDB (also tried using the MSOLEDBSQL) to connect to local sql server express 2014 (ver 12.0.2). The program always creates 2 connections, one for IDBCreateCommand and one for iOpenRowset which is used for fastload. The program is functioning well but it keeps on creating RING_BUFFER_CONNECTIVITY LoginTimers logs in sys.dm_os_ring_buffers when I try to release the database connections. No error were created in SQL server logs.
Using the SQL profiler, I know that the logging of RING_BUFFER_CONNECTIVITY happens during Audit Logout of the database connection, though I have 2 connections, only one of them is creating the RING_BUFFER_CONNECTIVITY log and it only happens when releasing connections that were not use (does not matter if it is using IDBCreateCommand or iOpenRowset). Using connections for running SQL query will not log RING_BUFFER_CONNECTIVITY when they are released.
The issue is also happening in MS SQL server 2016 express (ver 13.0.4001) but not in MS SQL server 2012 express(ver 11.0.5058), I am really running out of ideas as to what is causing this. Is there some added feature in SQL server 2014 and later versions that warns user of unnecessary database connections that were created? Like connections that were created but not even use? (I tried proving this by creating database connections using MS SQL management studio then closing it afterwards and it does not create a RING_BUFFER_CONNECTIVITY log... but looking at the sessions created using OLEDB and MS SQL management studio in sys.dm_exec_sessions.. sessions created using OLEDB has memory_usage = 0, while the latter has memory_usage = 3).
What am I missing?
Attached is the sample record created in sys.dm_os_ring_buffers.
I am making a website for PvP servers in PHP language. I have to comply with my own server so that my software does not have w-a-r-e-z. But I have to connect to the client's database with sql remote. (SQL Server 2014).
While the script is running very fast on the local connection, the remote sql connection opens 1-2 minutes late. This, in turn, will not please the customer. I can not imagine if they think you get 500-1000 hits. What can I do in this situation?
My organisation has taken a decision where i am asked to move the complete application along with Databases from azure PAAS to Google IAAS or on Premise architecture.
I had installed sql server 2016 and tried to restore a DB after taking back up from azure to On premise sql server and it got successfully restored. The .bacpac file size was 500MB. I used import functionality of the sql server to restore the Azure DB. How ever when i tried restoring the DB with .bacpac file size of 2 GB i got below errors:
Error SQL72016: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
The statement has been terminated.
Error SQL72045: Script execution error. The executed script:

I tried finding some knowledge doc to migrate DB from Azure PAAS to IAAS or on premise but couldn't find any.
Need help on this.
P.S. All my azure DB are on V12.
Its due to migration take long time, Please use SQL Database migration wizard, which can break data and schema transfers into multiple operations.

I installed OpServer on an virtual Server running Windows Server 2012 R2 with 2.5GB of RAM. I configured the SQLSettings.json to monitor the SQL Server cluster (SQL Server 2014 SP1). The cluster has three nodes at the moment with about 200 databases, more or less equally distributed.
The server, on which OpServer runs, is not busy with anything. The SQL Servers are also very relaxed.
Installation was "a snap". Configuration as well..
But now i have the issue, that the "main screen" does not refresh itself, even with "refreshIntervalSeconds": 20 in the SQL config file.
I tried to change the configuration, so that only the instances of the three SQL Servers are shown, but that does not change the time it takes to manually refresh.
If I press "refresh" it takes about 23 seconds until the screen is shown again.
Then, why does OpServer not refresh automatically? Do I need to configure something more??
If I run it locally on my PC, configured to some other SQL Server database servers, the refresh works and the manual refresh is quite fast. I cant test it with the same cluster servers on my local machine due to some multi domain configuration and firewall settings, which are not in my responsibility...
Does any one have an idea why I don't get an automatic refresh and why the manual refresh takes so long?
Thanks
I've changed the Connection Timeout to 10 seconds.
'...;Connection Timeout=10;..."
The code uses EF 6, .Net 4.5.1.
SQL Server Client has both tcp/ip and Named Pipes enabled.
Disconnected from the Network and then start debugging.
The timeout error happens at the 1 minute mark.
This seems to indicate the error happens when the sql server is not located.
Is SQL Server Ado.net client code is setting the network timeout?
I had thought this was fixed a while ago, like back in 2.0 days.
