I am trying to load from a SQL Server 2012 to Azure SQL Server using Talend. Job will read all the data from the source DB and load into destination. All the jobs are doing truncate and load. Lot of tables have records more than 7 millions. 5 tables have nearly 25 million records. I have one master job which will trigger all the jobs in parallel. I am facing a com.microsoft.sqlserver.jdbc.SQLServerException: Connection timed out (Read failed) issue.
When anyone of the job/table throws this error, all the jobs that are running parallelly also throws the same error. What is the reason for this issue and how to fix it?
Thanks,
"When you connect to a SQL Server 2012 instance running on Windows Server 2012, you get time-out error messages."
It's possible that the test server didn't get the same Windows updates as the production server. That might explain why production code and configuration are identical.
This is the Original Post, this issue might be caused by something unrelated to Java JDBC, such as SSMS or applications that do not use JDBC.
Verify that you can ping the SQL Server-installed server.
Verify that the SQL Server instance is up and operating.
Double-check that the connection codes you used are valid.

I have a .vbs script which is carrying out some modelling. This script is fired via a windows scheduled task and performs a fair amount of database selects, inserts and updates.
It has run many times over the years on SQL Server 2008 R2. Its now trying to run on win2016 Server running SQL Server 17.4. The job will run for a couple of hours ideally. Its stopping a little over an hour after almost 10,000 successful inserts, it throws me this error:
Database Error: -2147467259 Microsoft SQL Server Native Client 11.0 : Named Pipes Provider: Could not open a connection to SQL Server [5].
Is this SQL Server taking its resources back for some reason? Any ideas on resolving this would be very helpful?
Update : I have reduced the workload of the script. Instead of running for a couple of hours it now runs for less than one hour. The first two runs have been successful, no issues.
i supose that you try to conect to another server or to the local server across with one computer with network , so check if you have this correct configuration :

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 have a Microsoft server 2012 running Microsoft SQL Server 2017 Express database. I am trying to log in through SQL Server Management on a remote machine but the log in loads forever and gives no error.
If I put in the wrong username and password I do get an error that the username and password is wrong and the error shows in the SQL Server log so it does seem to be making some type of connection.
When I connect on the local server it connects right away.
I have TCP enabled in the server configuration.
Does anyone know why this hang might be happening?
Only reason seems to be large database server with too many fragmented databases and may be slow network speed at the moment.
I'm Trying to created a shared Data source from a sql server that is not local. the host of SSRS is a sql server 2014 and the DB source is a sql server 2008 R2.
I'm getting the same error whatever I do, which is
"An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)"
I know everything is correct because even though I get this error when I run the report, in MSSQL report builder when I create a dataset and go to query designer and run the query it actually runs without any issues.
furthermore also in report builder when I try to do a connection embedded in my report and when I'm in the connection builder (connection properties) and I test the connection from there it gives me "the test connection suceeded" however when I click ok, go back to the datasource properties, and click "test Connection" it fails and gives me the error above.
If I try to test a shared connection on the server it will fail too.
I've tried connecting in many different ways (using windows athentication (my user is admin on the server), SQL server authenticationm, promting, etc) but they all failed.
I've been at this for a while, the server is also accesed by a remote PHP server so I doubt there is any real issue on the SQL server. I've tried deactivating all of the firewalls I saw but I doubt it's a firewall issue since I"m able to do all these connections.
the issue was the port 1433 that didn't work between the SSRS server and the datasource server. however it did work between my computer and the sql server.
what was happening is that when I tested the connections, the first test was a quick test and went through my computer to test the connection thus it was sucessfull. when it did the real test it went through the SSRS server and it failed there.
the same logic applies when I did my requests, when I tested the dataset it worked because in report builder it went directly to the database through my computer, when I tried to run the report it went through the SSRS server and failed there.
so there is some issue with the firewall even though it is turned of on both servers it's the connection between the two that isn't working.
I usually create queries using Visual Foxpro 9.0 from a desktop computer to a MS SQL Server 2005 running on Windows Enterprise Server (2003). My queries are repetitive and sometimes, one session would query the SQL server 200,000 times in rapid succession. For the first few days, my program is running fairy well but then suddenly the SQL Server is refusing to process the queries.
On checking the logs in the SQL Server, I found out that a certain spid is killing my query process:
Process Id 71 was killed by Hostname SQLSERVER, Host Process ID xxxx.
I am confused because the hostname is not the SQL Server I am querying but another SQL Server.
From the activity monitor I noticed that the offending Process ID has the following information:
62 NO sa master sleeping 0 AWAITING COMMAND Sql Agent - Generic Refresher ..
The details shows a message:
SET NO_BROWSETABLE ON
Lastly, thinking that it may be a problem with visual FoxPro, I tried running queries from the desktop machine from within SQL Server Management studio, I still encountered the same problem when I tried queries to the SQL Server:
A transport-level error has occurred when sending the request to the
server. (provider: TCP Provider, error: 0 - An existing connection was
forcibly closed by the remote host.)
It's mind boggling because I am able to establish connections but my queries are refused by the server. Again, thinking that my desktop is the problem, I tried running the queries from another computer. It was running at first then suddenly the same problems occurred. Now these two desktops are refused by the server.
I am thinking that this might be a security but I don't know how to resolve this problem.
We also tried to restore our database backups to another host, the same scenario happened... Fine at first then the problem appeared after a few query sessions.
The following are the ODBC SQL Server Drivers:
Microsoft Ole DB Provider for Sql Server
Sql Server Native Client 10.0
Sql Server Native Client 11.0
I have search the web for a possible solution and I tried the suggested solutions, spid blocking, chimney offloading, rss, among others but to no avail. Please, In need your expert advise!
Thank you in advance.
