SolarWinds does not support case-sensitive databases.

SolarWinds supports the following collations on the SQL Server:

  • SQL_Latin1_General_CP1_CI_AS
  • SQL_Latin1_General_CP1_CS_AS
  • German_PhoneBook_CI_AS
  • Japanese_CI_AS
  • Chinese_PRC_CI_AS


SolarWinds supports the following database collation:



These collations are supported when the SolarWinds server locale is set to en-US and the default login language is set to us-english.  Other configurations are not supported.


Orion Platform versions running 2015.1 or later


If you do not use a supported collation, you must re-install your instance of SQL and re-install it with the correct collation.

  1. Create a backup of your data.
  2. Re-install your SQL instance with a supported collation.
  3. Re-create your tables.
  4. Import your data.

It is also possible to change SQL Server Collation manually via cmd prompt command.
Doing so would mean your DBA would need to take ownership. SolarWinds cannot take these steps as there are risks involved and DBA will need to process with care.

Process below is useful where a new SQL Instance has just been installed and no database has yet been attached or created.

If you need to edit the SQL Server Instance Collation without reinstalling:

1. Check Collation in SQL Management Studio:



2. If need to edit the SQL Instance Collation,  stop the SQL Server Instance. (You can use Services.msc, cmd or SQL Management Studio to do this)



3. Execute the command below. The parameter -s is only necessary if more than one SQL Server instance exists on the target machine. Parameters used: 

  • [-m] single user admin mode 
  • [-T] trace flag turned on at startup 
  • [-s] sql server instance name 
  • [-q] new collation to be applied

Some SQL text will appear and at end of large amount of text will be Collation has updated successfully. From this point no user action is required, close the cmd prompt window after the execution ends.

sqlservr -m -T4022 -T3659 -s"MSSQLServer" -q"SQL_Latin1_General_CP1_CI_AI"
