Selecting a DBMS

When installing Administration Server, you can select the DBMS that Administration Server will use. When selecting the database management system (DBMS) to be used by an Administration Server, you must take into account the number of devices covered by the Administration Server.

The following table lists the valid DBMS options, as well as the restrictions on their use.

Restrictions on DBMS

DBMS	Restrictions
SQL Server Express Edition 2012 or later	Not recommended if you intend to run a single Administration Server for more than 10,000 devices or to use Application Control.
Local SQL Server edition, other than Express, 2012 or later	No limitations.
Remote SQL Server edition, other than Express, 2012 or later	Only valid if both devices are in the same Windows® domain; if the domains differ, a two-way trust relationship must be established between them.
Local or remote MySQL 5.5, 5.6, or 5.7 (MySQL versions 5.5.1, 5.5.2, 5.5.3, 5.5.4, and 5.5.5 are no longer supported)	Not recommended if you intend to run a single Administration Server for more than 10,000 devices or to use Application Control.
Local or remote MySQL 8.0.20 or later	Not recommended if you intend to run a single Administration Server for more than 50,000 devices or to use Application Control.
Local or remote MariaDB Server 10.3, MariaDB 10.3 (build 10.3.22 or later)	Not recommended if you intend to run a single Administration Server for more than 20,000 devices or to use Application Control.

If you are using SQL Server 2019 as a DBMS and you do not have cumulative patch CU12 or later, you have to perform the following after installing Kaspersky Security Center:

Connect to SQL Server using SQL Management Studio.
Run the following commands (if you chose a different name for the database, use that name instead of KAV):
USE KAV

GO

ALTER DATABASE SCOPED CONFIGURATION SET TSQL_SCALAR_UDF_INLINING = OFF

GO
Restart the SQL Server 2019 service.

Otherwise, using SQL Server 2019 may result in errors, such as "There is insufficient system memory in resource pool 'internal' to run this query."

Concurrent use of the SQL Server Express Edition DBMS by Administration Server and another application is strictly forbidden.
