Error "no sqljdbc_auth in java.library.path" installing TeamCity on Windows Server 2012

Question

I am installing TeamCity on a Windows 2012 Server. I'm at the database connection setup screen but getting this error.

"SQL error when doing: Taking a connection from the data source: no sqljdbc_auth in java.library.path"

I've copied the sqljdbc_auth.dll to the C:\\Windows\\System32 folder and added a system environment variable java.library.path that points to this folder.

Answer 1

Teamcity installs the 32-bit version even if you're on a 64-bit platform unless you deliberately use 64-bit. So I am just going to give you the 32-bit instructions for using Windows authentication with Teamcity SQL database setup. The instructions are the same for the 64-bit setup, just change x86 to x64

1. Create an empty database in SQL server
2. Make sure the Windows account configured on the TeamCity service(s) have access to the database
3. Copy sqljdbc42.jar to <TeamCity_data_dir>\\lib\\jdbc\\sqljdbc42.jar
4. Copy auth\\x86\\sqljdbc_auth.dll from the Microsoft download to <TeamCity_data_dir>\\lib\\sqljdbc_auth.dll
5. Open System > Advanced System Settings > Environment Variables and add a System variable TEAMCITY_SERVER_OPTS set to the value -Djava.library.path=<TeamCity_data_dir>\\lib or run setx TEAMCITY_SERVER_OPTS=-Djava.library.path=<TeamCity_data_dir>\\lib
6. Click OK on all dialogs and restart the Teamcity services.

Now you can connect Teamcity to the SQL server using Windows Authentication after which the wizard will create the database.

Edit: January 27, 2020

With the 2019.2.1 update I've had to move the sql_jdbcauth.dll file to <TeamCity_data_dir>\\system\\caches\\jdbc\\native\\windows-i386 This could be just a bug in the upgrade process.

This

helped me.

I used the JDBC 4.1 version.

Answer 3

I managed to resolve the issue by using SQL Server authentication instead of Windows authentication during the database configuration setup. Not sure why this should have fixed the error as it relates to a Java environment variable, but I can only assume that the error was generated by it's failure to login to the database and for some reason threw an unrelated error instead.

This appears to be an error with TeamCity throwing the wrong error message. If you get this error, try switching to SQL Server authentication.

Answer 4

如果您在 32 位上运行，您只需将sqljdbc_auth.dll的 x86 版本（从 jdbc 下载）复制到<TeamCityProgramDir>\\bin 。

Answer 5

You should check your TeamCity server log. Mine (located at c:\\TeamCity\\logs\\teamcity-server.log ) mentions the following:

[2019-03-20 07:54:56,045] INFO - jetbrains.buildServer.STARTUP - Native library sqljdbc_auth.dll was not found under either E:\\BuildServer\\lib\\jdbc\\native\\windows-i386 or E:\\BuildServer\\lib\\jdbc\\native; will continue looking in sun.boot.library.path and java.library.path.

After putting the sqljdbc_auth.dll library in E:\\BuildServer\\lib\\jdbc\\native\\windows-i386 and restarting the service everything was fine and dandy; without having to meddle with bin folders (they get reset during TC upgrades) or having to define environment variables.

Answer 6

In my case it didn't worked because there were some files from previous install and version TeamCity isntallation. I uninstalled TeamCity, deleted all TeamCity folders and installed again. Then it worked like a charm.

Answer 7

I was running into this issue today with TeamCity 10.x, with bundled Java, and I wanted to migrate an existing, internal, database to SQL Server.

1. Follow Setting up TeamCity with MS SQL Server until you need to setup the JDBC Driver.
2. Log into your TeamCity server with the same Windows account you setup SQL Server with.
3. With the current version they say to download the 6.0+ driver, but then reference the 4.x version. You want the version at Downloads\\Microsoft JDBC Driver 6.2 for SQL Server\\sqljdbc_6.2\\enu\\mssql-jdbc-6.2.2.jre8.jar , and to copy it to C:\\ProgramData\\JetBrains\\TeamCity\\lib\\jdbc\\mssql-jdbc-6.2.2.jre8.jar .
4. From that same 6.x driver download, copy Downloads\\Microsoft JDBC Driver 6.2 for SQL Server\\sqljdbc_6.2\\enu\\auth\\x86\\sqljdbc_auth.dll to C:\\ProgramData\\JetBrains\\TeamCity\\lib\\sqljdbc_auth.dll .
5. Add a new System Environment Variable called TEAMCITY_SERVER_OPTS with the value of -Djava.library.path=C:\\ProgramData\\JetBrains\\TeamCity\\lib .
6. So that the MaintainDB tool works, add another System Environment Variable called TEAMCITY_MAINTAINDB_OPTS with the same value ( -Djava.library.path=C:\\ProgramData\\JetBrains\\TeamCity\\lib ).

Now you can run MaintainDB without getting an error about the sqljdbc_auth.dll not being in the JAVA library path.

See Creating Backup via maintainDB command-line tool - maintainDB Startup Options for why both environment variables need to be set.
