Hello,

I created a small test application that emulates the way a real application works with the Oracle DB (using multiple transaction objects). After I'd deployed it to PowerServer and run it, I got an error message "Connection request timed out" in SQLErrText of a transaction object after calling the connect statement. I'm a little lost as to how to troubleshoot this.

I may guess that it's either that the webserver can't connect to the Oracle server or that there's something wrong in my transaction to cache mappings. But I don't really know how to test that the webserver can connect to the Oracle DB using the data I entered in the cache definition. It's a clean PC with no Oracle client installed, so I can't use the usual tnsping/sqlplus checks. Besides, that wouldn't help understanding whether the webserver can connect using the Oracle .NET Core driver and the data from the cache settings. Could someone suggest how to do this before looking into transaction to cache mapping?

Best regards,
Konstantin
