I have migrated my PowerBuilder application to PowerServer 2021. I have been able to deploy to a Cloud test environment. My application starts up, but I have been unable to log in. I use an INI file to create the connection to the database. I have ensured that the Applicaiton.json has the appropriate connection information as well. I haven't figured out how the connection is established in this new version; this isn't working.

I can connect to the database using SQL Management and have a valid ODBC connection created. 

Fiddler debugging information from the "POST /api/ServerApi/ConnectAndCreateTransaction HTTP/1.1" call:

{"version":"1.0","requestid":"F671467E-C493-4409-AAE5-9BC9D05B4CFB","appname":"perfser_cloud_1","session":{"errcode":0,"errmsg":null,"sessionid":"37A0CC0B-5E82-44EC-AE7F-FDB94111E465"},"type":7,"transaction":{"sqlcode":-1,"sqldbcode":-1,"sqlerrtext":"A network-related or instance-specific error occurred while establishing a connection to SQL Server.

I am new to ASP.net development/deployment.

Any advice? Or can anyone point me to some documentation.

Thank you,

Teresa

Hi Theresa,

First of all, PowerServer is not client/server.  The database connection string is done in the C# Web API project... specifically the applications.json file.  The connection string in your INI has no affect.  

Secondly, for SQL Server database you cannot use ODBC... you must use the native driver, which is automatically incorporated into the Web API project.  So basically, you do not need to setup ODBC DSN.

I recommend you spend time reading the DB configuration guide: https://docs.appeon.com/ps2021/working_with_database_connections.html

Best regards,
Armeen

Yes. Everything is on one machine.

Hi Teresa,

Is the Database accessible from the machine hosing the Web APIs?
