GeneXus Access Manager platforms are a set of external executable files and libraries (.jar, .rb. and .dll files) which implement GAM and all the GAM API.
The GAM external objects consolidated in the KB when GAM is activated (Enable Integrated Security property is set to TRUE) allow to access the GAM API. The mentioned external libraries implement the GAM API. Those libraries are dependent on the platform used (SQL Server, Mysql, etc) and are required for using GAM at compile and execution time.
The GAM platforms are also needed during the F5 process: connecting to GAM database, GAM tables creation, GAM metadata initialization, GAM Applications Registration process and the generation of Automatic Permissions generated by GeneXus.
There are requirements that must be met by the Genexus applications to be successfully compiled. One of them is to reference the appropriate GAM platform libraries depending on the generator and DBMS used.
- In the case of java applications, at compile time you need to specify in the Java Classpath Property all the .jar files belonging to the corresponding platform.
- The same for NET applications in which case you need to specify the Compiler Flags property = /r:bin\Artech.Security.API.Common.dll.
- In the case of Ruby generator, you do not need to do anything special in prototyping time.
As stated previously inside Genexus IDE the GAM platforms are used, and it is always used .NET for performing the necessary operations (connecting to GAM database, GAM tables creation, GAM metadata initialization, GAM Applications Registration process and the generation of Automatic Permissions generated by GeneXus).
So you always need .NET GAM platform installed for the DBMS you are using. As a consequence, you need to be able to connect to the DBMS using ADO Net.
In runtime, the GAM platform libraries need to be located in the web application.
- In the case of Java, they must be located under the lib directory of the web app.
- In the case of .NET generator, they have to be located under the bin directory under the web application directory.
- For Ruby applications, they are under the web application directory.

GAM platforms flavors
The GAM platforms are distributed for all the possible combinations: Mysql, SQL Server, Oracle, Informix, DB2 UDB, DB2 iSeries and Postgresql for Java and NET generators. In the case of Ruby only SQL Server and Mysql are supported.
By default, when Genexus is installed only two of these platforms are installed: SQL Server and Mysql. These are named the standard GAM platforms.
Using a non-standard GAM platform
If you want to use a DBMS other than SQL Server or Mysql, the GAM platform corresponding for this DBMS needs to be installed using the gamplatforms.exe setup located under Genexus installation folder Library\GAM\Setup.
The gamplatforms.exe is a setup which detects any other previous versions and suggests to install the new upgrade or build of the platforms.
Working in Genexus IDE, when you change the GAM datastore and there is no platform installed for it, the gamplatforms.exe setup launches automatically in order to help the user to install the required platform.
You need to keep updated with the GAM platforms version. When installing a new Genexus upgrade or version it is mandatory to update the GAM platform for the upgrade or GeneXus version. This is automatically controlled in the GeneXus setup where you are asked to upgrade the GAM platforms which are already installed.
