I need to connect to a remote database (Oracle) using a MS SQL Server (2019) linked server. What I did so far:
Installed Oracle Instant Client x64 and the ODBC drivers on the machine where the SQL server is running
Created a symlink to the central TNSNAMES.ORA (on a file share in the network) inside the Oracle Instant client folder.
Set the necessary environment variables
Created an ODBC connection to the database on the Oracle server on this machine
Restarted MS SQL Server
Created a linked server (Microsoft OLEDB Provider for ODBC Drivers) in the SQL instance
When connecting to the SQL Server using sqlcmd on this machine (I did not install SSMS there), I can query the linked database using OPENQUERY(). I can also read the file TNSNAMES.ORA using this command (note, the given file is the symlink, but it displays the contents of the linked file, as it should):
SELECT * FROM OPENROWSET(BULK 'C:\InstantClientx64\tnsnames.ora', SINGLE_CLOB) TNSNames
So far, everything is fine.
Now, when I connect to the SQL Server from my workstation using SSMS, i get the following error when trying to read TNSNAMES.ORA using the command above:
Cannot bulk load because the file "C:\InstantClientx64\tnsnames.ora" could not be opened. Operating system error code 5(Access is denied.).
I created a file test.txt in the instant client folder containing something like "Am I allowed to read this?" - and I was, no problems.
I started procmon on the server to find out what happens. When using the above command on the SQL server, I get a REPARSE (because it's a link!), and then SUCCESS, the file is displayed in the sqlcmd console.
When using this command in SSMS (on my local workstation), first appears the REPARSE (OK), then ACCESS DENIED.
In both cases it is the same user account which is displayed as "Impersonating" in the procmon's details. There is definitely no problem with a firewall, and the read permissions on the tnsnames.ora file on the network share are granted for Everyone. I am also able to create an ODBC item on the local workstation, and can connect and query the database from here.
I have done this in the past I don't know how often, and never had problems. What am I missing?
Why are you trying to read the tnsnames.ora file via SQL? The Oracle libraries will (should) internally open it and use it when your app connects to the DB.
The default location for network config files is shown in the Instant Client installation doc. In your case it will be C:\InstantClientx64\network\admin. Unless you have set the TNS_ADMIN variable, then start by creating this subdirectory and putting tnsnames.ora in it.
(A future version of Instant Client on Windows will create the network\admin subdirectory automatically, similar to the way it is created with the Linux Instant Client packages).
I stopped SQL Server (MSSQLSEVER) and SQL Server Agent services and deleted the backup file and data file was located at C:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL. Log file is still there:
Now I can't connect to SQL Server
Can not start SQL Server (MSSQLSERVER) and SQL Server Agent services as well
Could you suggest me a solution to connect to my SQL Server instance?
Image of the error message:
I really do not have enough information to diagnose this issue.
However, I have two ideas of what you did.
1 - What you showed me in the picture is the data and log directories. They contain all the system databases by default. See image below.
If you have not done a shift delete of the files and directory, stop the sql server instance and recover them from the recycle bin and restart the sql server instance.
Be VERY careful when deleting directories.
If you do not have these files handy, you might have to re-install SQL Server.
2 - If you data files are in another directory, which I doubt. Then, look in the windows event log and/or sql error log for errors. Please post more details.

You're not going to be able to connect to the SQL until the agent service is running again.
I think I need more information about what happens when you try to start the service. Also, I'd probably (if possible) try to restart the machine. Though that probably shouldn't be necessary, dependent on OS you're running it might help.
If you could post what happens when you try to start the service, that might be helpful.
Is the SQL service running? The agent service is not required for connecting to an instance. To regain access to SQL server after deleting required files, read the following msdn article: https://msdn.microsoft.com/en-us/library/dd207004(v=sql.120).aspx
I have two server. Server A is the application server, and server B is the database server. Normally I use SQL Management Studio in Server A to query. I intend to do a database backup (.bak), but whenever I do this through SQLMS, the file is created at server B. I dont have access to do a remote connection to server B.
How do I get the backup file?
You can specify a UNC path for the target of the backup. Keep in mind, however, that the account that the SQL Server service runs under will need network access to that path. This is one good reason why the SQL installer asks you which account to run the services under.
I ended up using generation script. But instead run all in a single script, I run 3 different script (create table, create stored procedure, and data) at a time. I do this because if I run in a single script, I ended up an error. By the way, the script can be compressed (zip) to give a smaller file size.
For some reasons I moved this folder : (Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL) to another drive, then returned it to the same location, but sql server has stopped working, showing this error when trying to start it again:
Windows could not start the SQL Server (MSSQLSERVER) on Local
Computer. For more information, review the System Event Log. If this
is a non-Microsoft service, contact the service vendor, and refer to
service-specific error code 3417.
I tried many solutions discussed in different forums, but none of them work for me.
The folder is not compressed or encrypted.
My sql server version is 2012:
Microsoft SQL Server Management Studio 11.0.3128.0
Microsoft Analysis Services Client Tools 11.0.3128.0
Microsoft Data Access Components (MDAC) 6.1.7601.17514
Microsoft MSXML 3.0 4.0 6.0
Microsoft Internet Explorer 9.0.8112.16421
Microsoft .NET Framework 4.0.30319.18047
Operating System 6.1.7601
Thanks for your kind help in advance.
Very simple to solve this problem.
Just open RUN window(Window+R) and type services.msc:
Services.msc window
Find the SQL within name column and right click on that.
right click on SQL as in screenshot
You will get properties option, click on properties.
One new window will be open and there you have to click on Log On tab. And select the Local System Account. then apply and okay.
Select Local system Account
After that come again in services.msc window. and right click on sql and click start.
And finally, SQL Server services started successfully. enjoy and keep learning.
Check if you did compress the driver or folder in where you put the .mdf file.
If so, plesae goto the driver or folder, change the compress option by
Properties -> Advanced and unticked the “Compress contents to save disk space” checkbox.
After above things, you should be able to start the service again.
Run this command after opening cmd as administrator
net start mssqlserver /T902
This command is called trace flag 902. It is used to bypass script upgrade mode. Every time when you try to start your sql service it also looks for script upgrades. and when the script upgrade fail your service unable to start. So, Whenever we have such upgrade script failure issue and SQL is not getting started, we need to use trace flag 902 to start SQL.
I hope this will help you..
In my particular case, I fixed this error by looking in the Event Viewer to get a clue as to the source of the issue:
I then followed the steps outlined at Rebuilding Master Database in SQL Server.
Note: Take some good backups first. After erasing the master database, you will have to attach to all of your existing databases again by browsing to the .mdf files.
In my particular case, the command to rebuild the master database was:
C:\Program Files\Microsoft SQL Server\110\Setup Bootstrap\SQLServer2012>setup /ACTION=rebuilddatabase /INSTANCENAME=MSSQLSERVER /SQLSYSADMINACCOUNTS=mike /sapwd=[insert password]
Note that this will reset SQL server to its defaults, so you will have to hope that you can restore the master database from E:\backup\master.bak. I couldn't find this file, so attached the existing databases (by browsing to the existing .mdf files), and everything was back to normal.
After fixing everything, I created a maintenance plan to back up everything, including the master database, on a weekly basis.
In my particular case, this whole issue was caused by a Seagate hard drive getting bad sectors a couple of months after its 2-year warranty period expired. Most of the Seagate drives I have ever owned have ended up expiring either before or shortly after warranty - so I'm avoiding Seagate like the plague now!!
This usually occurs when the master.mdf or the mastlog.ldf gets corrupt . In order to solve the issue goto the following path C:\Program Files\Microsoft SQL Server\MSSQL10.SQLEXPRESS\MSSQL , there you will find a folder ” Template Data ” , copy the master.mdf and mastlog.ldf and replace it in C:\Program Files\Microsoft SQL Server\MSSQL10.SQLEXPRESS\MSSQL\Data folder . Thats it . Now start the MS SQL service and you are done
I have had the same error recently. I have checked the folder Log of my Server instance.
x:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\Log\
and I have found this errors in logs
Starting up database 'master'.

SQL Server shutdown has been initiated
So for me it was an easy fix. I just added proper access rights to this files to the sql server service account.
I hope it will help
In My case I had to Upgrade the SQL Server since evaluation licence had been expired.
What is System Event Log saying?
Have you tried to repair:
Sql Server Installation Center -> Maintenance -> Repair
I was getting this error today. And above answers didn't help me. I was getting this error when I try to start the SQL Server(SQLEXPRESS) service in Services(services.msc).
When I checked the error log at the location C:\Program Files\Microsoft SQL Server\MSSQL13.SQLEXPRESS\MSSQL\Log, there was an entry related TCP/IP port.
2018-06-19 20:41:52.20 spid12s TDSSNIClient initialization failed
with error 0x271d, status code 0xa. Reason: Unable to initialize the
TCP/IP listener. An attempt was made to access a socket in a way
forbidden by its access permissions.
Recently I was running a MSSQLEXPRESS image in my docker container, which was using the same TCP/IP port, that caused this issue.
So, what I did is, I just reset my TCP/IP by doing the below command.
netsh int ip reset resetlog.txt
Once the resetting is done, I had to restart the machine and when I try to start the SQLEXPRESS service again, it started successfully. Hope it helps.
Go to the services and check if the SQL Server (MSSQLSERVER) service is running stop it and start your SQL Server (SQLEXPRESS) service it should work.
see the image:
Make sure both drive have the same partition - ( like FAT or NTFS, preferably NTFS ) also make sure he NETWORK SERVICE account, has the access.
Database rebuild fixed it for me as well. Also had to restore the old database from backup as it got corrupted during power outage...
The copy master.mdf procedure did not work for me.
i had the same problem before
the error code 3417 : the SQL SERVER cannot start the master database,
without master db SQL SERVER can't start
MSSQLSERVER_3417
The master database records all the system-level information for a SQL Server system. This includes instance-wide metadata such as logon accounts, endpoints, linked servers, and system configuration settings. In SQL Server, system objects are no longer stored in the master database; instead, they are stored in the Resource database. Also, master is the database that records the existence of all other databases and the location of those database files and records the initialization information for SQL Server. Therefore, SQL Server cannot start if the master database is unavailable
MSDN Master DB
so you need to reconfigure all settings after restoring master db
solutions
replace master mdf and ldf files with the same files from another instance of sql Server as long as its the same version reference
Rebuild System Databases refrence
reinstall sql server
I copied a master.mdf und mastlog.ldf from another Computer (luckily, we have a lot of Clients with the same configuration, otherwise template data would be perhaps necessary). I backed up the damaged master.mdf and mastlog.mdf. After that I replaced the bad ones with the ones from another Computer. And it worked. I needed to start the MSSQLSERVER Service of course. But, after that I had Problem that the user was already existing but orphaned (error code 15023), I executed the query
USE Database_name
EXEC sp_change_users_login 'Auto_Fix', 'username'
after that, everything was working smoothly. Hope this helps you and many thanks for this thread, saved me :)
Just rename the current ErrorLog to any other name like Errorlog _Old and change any old Log file to Error log file
try to start the SQL server services.. That's it. it will work..
Sql server error log file got corrupted. that is why it gives the problem even when you have all permissions.. when you delete it. new file will be generated.
I encountered this issue after changing database location. And I solved it by moving system databases back to their default locations. Although I will recommend not to move system databases like master and model to some other location. But if you want then you can refer to this article: https://learn.microsoft.com/en-us/sql/relational-databases/databases/move-system-databases?view=sql-server-2017
Re-entering credentials will help to start the services:
Start > Services
Right click on SQL Sever > Properties
Log On
Re-enter credentials and apply
Start the services now
The reason behind getting this Error Code : 3417 may be as follows:
One cause may be due to the Network account for the Data folder in
Program files.
The other reason may be because of some Windows
settings changed somehow.
Example: If for some reasons you have moved this folder (Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL) to another location then returned it to the same location. So, though it was returned to the same location the server may stop working and show error code 3417 when trying to start it again.
How To Fix SQL Error 3417
Go to "C:Program Files Microsoft SQLServerMSSQL.1MSSqLData"
Security/Permission settings
Network Service Account
Add a Network Service account
Then again check all
As stated here, you can try this third party tool as well.
A few times now, I've experienced various instances MS SQL Server to fail with this error after a Windows update. Most of the quick fixes above did not work for me.
What did:
copy all production databases over to some safe place
remove everything SQL Server via add/remove programs
get the latest SQL Server Express or Dev & install it
move the databases over to their home and reattach them.
For me, this was the fastest solution. Trying to find the cause of the error and fixing it is an afternoon of googling misty error messages. But YMMV.
In my case problem was about evaluation period expiration. I also went through this thread of StackOverFlow.You can investigate your problem by going to Event Viewer --> Windows Log (Application) and then search for your error id. For Step by Step guide to view error id in event viewer visit this...
I'm having a rather frustrating issue with using an SSIS Flat File source. I am developing an SSIS package on my local machine via VS 2008 and I'm using a flat file source that is stored locally. However, I need to deploy this package to a remote server that hosts our SQLServer and then run it as a scheduled job from that host. However, when I deploy the package, it obviously can't read the flat file source from my machine and fails the job. I have tried putting the file directly on the remote host in the exact same file location (ie. C:\Source.txt) but to no avail. Any ideas on how I can get my deployed SSIS package to read a flat file source?
Hopefully I'm just missing something extremely simple and will ultimately have a "DUH" moment, but if anyone can help I will greatly appreciate it.
If the account under which the SSIS package (for instance the SQL Server Agent service account) is running doesn't have rights to open the file, you will also have problems. So not only does the file need to be on a path that is valid relative to the server running the package, it must also have rights.
Nice answer by Cade.
Remember that you create a SQL Server Job, by default it runs under the credentials of the Service Account assigned to the SQL Server Agent.
If some steps on a Job need some permissions not owned by the Service account you can define a SQL Server Agent Proxy.
That way you can keep the principle of least privileges.
More info on how to create a Proxy here.
