Currently supported relational database engines are: 

Microsoft SQL Server (connection via ODBC drivers) 

Firebird SQL Server (direct connection via respective drivers) 

b)

Direct client connection to a different database engine 

It is also possible to connect to the above database engines directly using native APIs or ODBC access 

without the AVG TCP Server. This configuration can slightly improve performance but requires that all 

AVG clients have all the necessary libraries (ODBC etc.) and are properly configured. 

For the connection of AVG clients and the AVGADMIN application to the database engine (which is 

acting as AVG DataCenter instead of AVG TCP Server), it is necessary to enter a correct connection 

string. You can generally enter any string into the field of AVG DataCenter connection within the 

Remote Administration component in AVG Control Center. The component parses the string and 

tries to guess what kind of connection it represents. According to the predicted connection, the 

connection mode is chosen. The most common alternatives are offered in a menu that can be opened 

by pressing the 

 button. After selecting the connection mode you have to enter the identification of 

a concrete computer with the server running. 

Connection possibilities are as follows: 

String begins with http:// 

HTTP connection is chosen (AVG TCP Server usage is supposed). String syntax corresponds to 

general URL syntax. 

String begins with direct=firebird 

Module for direct connection to Firebird database server will be used. 

String begins with DSN= 

Specification of data source (Data Source Name) defined on a workstation follows. Module of 

ODBC connection will be used.  

Attention: 

It is necessary to have all the ODBC or direct connection drivers installed on client machines. When 

you are using, for example, ODBC for connecting to MS SQL Server, all of the AVG clients must have 

the corresponding MDAC component installed and configured properly. 

c)

AVG DataCenter configuration for a different database engine 

AVG DataCenter can be stored into a new or currently existing database. The installation SQL scripts 

are available as a part of the AVGADMIN installation; these scripts can be used for creating an empty 

AVG DataCenter in the respective database server. 

The scripts for the AVG DataCenter initialization according to the selected database server are 

generated in the C:\Program Files\Grisoft\DataCenter Scripts directory by default. 

7.10 Number of Clients Connected to AVG DataCenter  

Based on the number of client stations with installed AVG Anti Virus that are connected to the AVG 

DataCenter it is necessary to select the appropriate database type considering the following limitations: 

a)

Embedded Firebird   is a standard part of the AVG Remote Administration installation (no extra 

licence is required); this database is recommended for maximum of 150 client stations
