im using oracle sql developer to make my database, but now i stopped to work.
it wrote this:
An error was encountered performing the requested operation:
Listener refused the connection with the following error: ORA-12514,
TNS:listener does not currently know of service requested in connect
descriptor
Vendor code 12514
i also tried to make new connection but it didnt help
pls help me,i dont know what to do, i need this to do my homework
when i tried to change connection it wrote this:
An error was encountered performing the requested operation:
ORA-01031: insufficient privileges
01031. 00000 - "insufficient privileges"
*Cause: An attempt was made to change the current username or password
without the appropriate privilege. This error also occurs if
attempting to install a database without the necessary operating
system privileges.
When Trusted Oracle is configure in DBMS MAC, this error may occur
if the user was granted the necessary privilege at a higher label
than the current login.
*Action: Ask the database administrator to perform the operation or grant
the required privileges.
For Trusted Oracle users getting this error although granted the
the appropriate privilege at a higher label, ask the database
administrator to regrant the privilege at the appropriate label. Vendor code 1031
Please check the services are running:
OracleOraDb11g_home1TNSListener and OracleServiceORCL.
You're going to have to do some troubleshooting; Here are a couple of suggestions:
ORA-12514 Tips
ORA-12514 TNS:listener does not currently know of service requested in connect descriptor
How to resolve error: ORA-12514
The service name ,you are using should be in sid column and not in service name entry box.
For example, the service name provided for you is overflow,you have to mention it in
ex:10.171.1.24:1521:overflow
Sid : overflow
Service : leave blank
Test the connection
Go to Services
check whether the "ORACLEServiceORCL" is running or not.
if not running then right-click on it and click start.
Your problem may solve this.
Happy coding :D
This worked for me- Close your SQL Developer and launch again.
I had the same issue after restarting my PC and could not access my local database. This fixed it.
Go to Run > services.msc > Services (Local) > OracleService
Right-click on OracleService > Properties > Log On
Make sure Local System Account is checked then press OK.
Stop the OracleService and restart it. It should be working now.
Mine was working fine till last night but this morning I found the said problem. I checked OracleOraDb11g_home1TNSListener and OracleServiceORCL was running and in "Started" status but still issue was there.
Just restarting both the services solved my issue. I suggest just try this once to save your time before exploring other solutions.
Cannot start LocalDB instance, I have installed and re-installed over and over.
Keep getting this error :
Start of LocalDB instance "v11.0" failed because of the following error:
Error occurred during LocalDB instance startup: SQL Server process failed to start.
Anyone any advice ? ?
Microsoft SQL Server 2012, i have ensured the FULL installation options, stopped all services SQL related and tried restarting .
sqllocaldb info
gives me :
Projects
v11.0
when i try
sqllocaldb start v11.0
I get the above error.
When all else fails and you don't care about data loss, delete and recreate your LocalDB\v11.0 database! At the command prompt
sqllocaldb delete v11.0
sqllocaldb create v11.0
(Sqllocaldb is in your PATH right? It was for me.)
I was getting a similar error, but when running
sqllocaldb start
The local db started successfully. Also when checking the event log I saw an error along the lines of
Windows API call WaitForMultipleObjects returned error code: 575
What fixed it for me:
In IIS, configure the app pool to run under an account with permissions to the DB on the server (advanced options of the app pool)
In the advanced option of the app pool, set Load User Profile to true
Reference: http://blogs.msdn.com/b/sqlexpress/archive/2011/12/09/using-localdb-with-full-iis-part-1-user-profile.aspx
It worths looking at LocalDB log files too, it is more detailed than event log:
%LocalAppData%\Microsoft\Microsoft SQL Server Local DB\Instances\ProjectsV12\error.log
Besides recreating the instance I had to delete the content of this folder:
%LocalAppData%\Microsoft\VisualStudio\SSDT\
This is where I have the mdf and ldf files.
My solution:
Go to: %LocalAppData%\Microsoft\Microsoft SQL Server Local DB\ and allow total control of the folder "Instances" to everyone group.
I know this is not OK but it solved my problem and i don't really care about the data of that folder as this is a developing and testing computer.
Same problem here. Here's how I fixed it using bits of the other solutions posted here.
I had dozens of these errors in the application event log:
Windows API call WaitForMultipleObjects returned error code: 575. Windows system error message is: {Application Error}
The application was unable to start correctly (0x%lx). Click OK to close the application.
Reported at line: 3730.
I realized that I had SQL Server Management Studio installed on my development machine, but no other SQL components. I installed the database engine, shared components, and localdb from SQL Express
https://www.microsoft.com/en-us/cloud-platform/sql-server-editions-express
After installing, I still get the same error in event log :(
Found this article:
Cannot start LocalDB
Run the following in cmd to get the localdb instance name:
C:> sqllocaldb info
In my install, I had:
MSSQLLocalDB
ProjectsV13
I ran the following to delete the instances:
sqllocaldb delete MSSQLLocalDB
sqllocaldb delete ProjectsV13
I ran into issues trying to delete/create these (sqllocaldb delete MSSQLLocalDB). I ended up deleting all of the folders and files under '%LocalAppData%\Microsoft\Microsoft SQL Server Local DB\Instances*' (You need to stop SQL Server and kill all sqlserver processes)
Then running 'sqllocaldb create' created and started the default instance and all files.
Had this issue suddenly too but saw nothing weird in logs. Was able to get it running by running the following in an administrator command prompt:
sqllocaldb start
I had this issue. I was trying to use Windows Authentication through an application, but the IIS App Pool credentials were wrong. I was using my Windows user name (ie: NETWORK\name) as my identity, but I changed it to the built-in "LocalSystem" and it worked.

What worked for me was the local IIS application pool I was using was the ApplicationPoolIdentity and that did not have permission to login to MSSQLLocalDB. As soon as a I changed the app pool identity to my windows login account - I was able to connect ok.
Had this issue on Windows 10 when our application was run with compatibility for Windows 8 enabled. Turning off the compatibility setting fixed it.
Before you try something drastic:
After waiting for about 5 minutes it "healed" itself.
(May be this is what this log message is pointing at: "The RANU instance is terminating in response to its internal time out")
I can not yet comment posts here but I really want to give a hint for the in my case extremely helpful post https://stackoverflow.com/a/30298863/8015089 above:
If your LocalDB instance is run by the Windows SYSTEM user (as in my case) the path to error.log is this (MS SQL Server 2012 Express LocalDB on Win11): C:\Windows\System32\config\systemprofile\AppData\Local\Microsoft\Microsoft SQL Server Local DB\Instances\<InstanceName> (enter this path subfolder by subfolder to avoid access problems!)
I am trying to deploy my website on windows server 2003.
Am i missing something or what is wrong from the following error message, how can I correct it? Thank

Typically, to troubleshoot this, you go to SQL Server Configuration Manager (SSCM) and:
ensure Shared Memory protocol is enabled
ensure Named Pipes protocol is enabled
ensure TCP/IP is enabled, and is ahead of the Named Pipes in the settings
Maybe it can help: Could not open a connection to SQL Server
Note : If this is a new instance of SQL Server be sure SQL Server and Windows Authentication is enabled
Right Click the Server in SSMS and pull up server properties
Go to Security--> Select 'SQL Server and Windows Authentication Mode'
Restart the Server and Login with the credentials
Check if your connection string has "Trusted_Connection=true" added.
I had this same error message, turns out it was because I didn't have mixed mode auth enabled. I was on Windows Auth only. This is common in default MSSQL deployments for vSphere, and becomes an issue when upgrading to vSphere 5.1.
To change to mixed mode auth you can follow the instructions at http://support.webecs.com/kb/a374/how-do-i-configure-sql-server-express-to-enable-mixed-mode-authentication.aspx.
I had the same error by in SQL Server Management Studio.
I found that to look at the more specific error, look at the log file created by the SQL Server. When I opened the log file, I found this error
Could not connect because the maximum number of ’2′ user connections
has already been reached. The system administrator can use
sp_configure to increase the maximum value. The connection has been
closed
I spend quite some time figuring this out. Finally running the following code fixed my problem.
sp_configure 'show advanced options', 1;
go
reconfigure
go
sp_configure 'user connections', 0
go
reconfigure
go

Edit
To view logs search for "logs" on windows startup button, click "view events logs". From there go to Applications under "Windows Logs". You can also choose "System" logs to see system wise errors. You can use filter on current logs by clicking "Filter Current Logs" on right side and then select "Error checkbox".
Just another possibility. I had to restart the sql server service to fix this issue for me.
The "real" error was in the SQL error log:
C:\Program Files\Microsoft SQL Server\MSSQL14.MSSQLSERVER\MSSQL\log\ERRORLOG
Path will depend on your version of SQL Server
You should enable the Server authentication mode to mixed mode as following:
In SQL Studio, select YourServer -> Property -> Security -> Select SqlServer and Window Authentication mode.
Goto to SQL server using windows Credentials - > Logins - > Select the Login - > in the Properties -> Check if the Log in is enabled/disabled.
If Disabled, make it enable, this solution worked for me.
Adding this to my connection string worked for me:
Trusted_Connection=true
In C# and SQL SERVER, we can fix the error by adding Integrated Security = true to the connection string.
Please find the full connection string:
constr = #"Data Source=<Data-Source-Server-Name>;Initial Catalog=<DB-Name>;Integrated Security=true";
By looking into SQL SERVER log file in "C:\Program Files\Microsoft SQL Server\MSSQL13.MSSQLSERVER\MSSQL\Log\ERRORLOG", it says
"Login failed for user 'XXXXX'. Reason: An attempt to login using SQL authentication failed. Server is configured for Windows authentication only. [CLIENT: ]"
The fixing method is to open "Microsoft SQL Server Management Studio" -> Right click the SQL server and then select "Properties" -> Security -> Change the authentication to mixed mode. -> Restart SQL server.
I was getting this error today. In my case, looking at the ERRORLOG file on the SQL server gave me this error:
Login failed for user ''. Reason: Failed to open the
database '' specified in the login properties.
This was because I had deleted the "Default database" of this user a few days ago. Setting the default database to my new database fixed the problem.
Hope this helps someone else.
I forgot to add the "Password=xxx;" in the connection string in my case.
I had the same error, Fixed it by ensuring that SQL server had SQL authentication mode enabled.
see images below.
To enable, go to server properties.
Click on the Security tab and select the SQL server and window server auth mode and press ok
You will need to restart the server for the changes to reflect, should be fine now.
Enable Mixed authentication mode while installing MSSQL server. Also provide password for sa user.
Hi Just enable both for server authentication as per screen shot attached below.
All good and valid courses of investigation especially the logs for more info.
For those hitting this it might be a simple gotcha where when you have created the DB User you may have enforced a password policy and left the user to change the password on first login (i.e. left the checkboxes around the password field at their default values).
Very easily done in SQL Management Studio and can of course cause authentication issues off the bat that are masked unless you look into the logs.
Check that the server name you're logging into with SQL Management Studio matches your connection string.
I was getting this error today.
It turned out that I hadn't realised the machine with SQL Server installed had multiples servers running. I had in fact put my database in a totally different server to the one I thought I was using. (So my connection string was pointing to a server with no database)
Hence, When .net tried to access the database it couldn't find anything and gave only a misleading error message about pipes.
I opened the correct server in SQL Management Studio, added my database to and then all worked fine.
(If the correct server isn't available in the dropdown, try browsing for it.)
In my case it was a spelling mistake in the database name in connection string.
This is old but I had the problem in the connect dialog that it was still defaulting to a database I had removed. And by running those commands the default database in the prompt wasn't changing.
I read somewhere I can't find now, that if you open the "Connect to Server" dialog and then select "Options" and select "Connection Properties" tab by typing the default database (no by selecting from the drop down) the database will then stay on that new value entered. This sounds like a flaw to me but in case someone was wondering about that, that should fix the issue, at least on SQL Server 2012
I know i am probably the only one that will have this problem in this way. but if you deleted the mdf files in the C:/{user}/ directory, you will get this error too. restore it and you are golden
I ran across this in a code-first application which expected the database to be there:
Make sure the database is created / the name in the connection string is correct.
I had the same problem. I tried all the suggested answers in this page but to no avail! Finally, I tried the steps below and it worked for me:
In SQL Server Management Studio Object Explorer, right-click the server, and then click Properties.
On the Security page, under Server authentication, select the new
server authentication mode, and then click OK.
In the SQL Server Management Studio dialog box, click OK to
acknowledge the requirement to restart SQL Server.
In Object Explorer, right-click your server, and then click Restart.
If SQL Server Agent is running, it must also be restarted.
Then try this in your Package Manager Console:
Scaffold-DbContext "Server=YourServer;Database=YourDB;Persist Security Info=False;User=YourUserName; Password=YourPassword; MultipleActiveResultSets=False;Encrypt=False; TrustServerCertificate=False; Connection Timeout=30;" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models -Context DatabaseContext -f
In my case, my situation was a little different.
1. My Mistake: I was missing a ";" in stringConnection. I know this is a newbie bug, but I am new to C # and SQL Server. I have one day :)
private string connectionString = "Data Source=localhost;Initial Catalog=FundamentalsCSharp"
+ "User=sa;Password=123456";
2. My Solution: Put a ";" it was missing after the phrase "FundamentalsCSharp" and it worked.
private string connectionString = "Data Source=localhost;Initial Catalog=FundamentalsCSharp;"
+ "User=sa;Password=123456";
3. Note: Change "FundamentalsCSharp" for your owned Initial Catalog.
I hope this can be of use to someone. Thanks!
In my case, my project is Asp.net Core 3.1 and this is my connection string
"ConnectionString": "Data Source=.; Initial Catalog=WebDB; user Id=sa; Password=123"
And database name in sql server webdb (lower case in sql server).
After many time change database name webdb in connecion string and worked fine.
For those doing entityframework code first, also check to enture you have done your migrations.
The best place to look for the root cause is the sql server error log
In my case My disk was full 99%, It worked after I freed up to 80% of the disk.
Scenario:
If i try to start the server as a window service it gives an error stating that ceradentials are not correct.However on correcting the credentials in boot.properties when i try to start the server again it gives the same error.Any alternative for starting the server.I gave the same username and password in my startup Script and Boot.properties.
Scenario 2: If i start the server remotely through console then will it come up?
Thanks in advance.
Regards,
Preet
If i try to start the server as a window service it gives an error stating that credentials are not correct.
Then they aren't. Maybe provide more details on what you do exactly and the error message.
If i start the server remotely through console then will it come up?
First, if your credentials are not correct, then it won't change anything. Second, if you don't have a node manager configured, this won't be possible. Provide more details.
I have this problem which I am trying to debug for a lot of time.
The setup is like this:
i. The application is a Windows application developed using VS2005, .net 2.0.
ii. I use the Cyrstal reports component Crystal Report Viewer and dynamically display various reports in the same form.
iii. The db is SQLSERVER Express 2005 and situated on a different machine.
When I run the application on the db server, I am able to view the report. However, when I run the application on a different machine which is connected to the above dbServer, I get an error. ( I dont get this error on my dev setup)

Use datasource=servername or ip address\instance name if available,port number
Default port number is 1433 or 1434
My problem was solved with this. Posting for the use of others.
If this is a standard installation of SQL Server Express, bear in mind that the only connection method installed by default is shared memory, and is only available on the server -- you would need to enable another connection protocol such as Named pipes or TCP/IP. To turn networking on, Use SQL Server Configuration Manager to enable relevant protocols and start SQL Browser.
It's telling you exactly what's wrong.

Great, we can't logon.

connection.
Okay. I bet we have "localhost" as part of the instance name in my connection string. Since I'm no longer on the "localhost", this obviously won't work. Let's try there first. Then perhaps it's the credentials that I'm using to query my database. Usually what I do is create a RO user that can only do selects on my db and use that for CR. If none of these are getting me close, let's try making sure that remote connections are enabled for SQLEXPRESS

Ok it's definitely a connection issue.
