Hi.

Those connectors are user in pb client server applications. Powerserver will use the appropriate connectors based on your database configuration (database option under server setup).Of course you should have the client portion of the database(s) you are going to use in your server... PS app will use the .net core driver. ASE 16 and SQL Anywhere will use odbc.

Andreas.

thanks a lot to both of them for responding quickly.

I'm migrating the project to PowerServer over IIS. and in the runtime folder (C:inetpub\wwwroot\ClientApp\CloudAppPublisher\runtime\22.0.0.1892) I have compressed connectors (zip files) with other files of adiitional features.

When does the end customer use these connectors in zip format? or why they are added in this path. ?

since the end customer only makes requests and receives a JSON package (at best)
thanks 

Hi Damian;

  You will notice that there is a "Database" tab in the PS Project.

   When you define a DBMS requirement in the PS Project's DB tab, the PB IDE will download (from the DBMS vendor) a Nuget package of their comparable DB Client driver written in C# for the PS Server to use. The PS project though does use that DB definition to verify your PB App's SQL with that DB connection to check it's System Table definitions in order to verify the DML & then to generate the C# Web API code (also any required required .NET DW objects).  HTH
