I have been using PowerBuilder R3 Build 2703 ( and deploying an application to PowerServer (PB Edition) 2020 Build 2703.00 (64 bit). I have tested my 64 bit Oracle and 32 bit Oracle connections from the PB front ends, and the PowerServer resources/data source, all make connections to the Oracle 19 database I have recently down loaded PB 2021 Build 1288, runtime and have been trying to configure the same Oracle connection in the PowerServer Project object. I downloaded the Oracle .Net driver, installed the Oracle driver and re-booted. I am getting the following error: OracleInternal.Network.AddressResolution when trying to test the connection in the (from the Web API tab) database Configuration area. How does one debug what the error is? I have tried some of the .Net sugguestions from a Google search.

After some playing in my System variables found that the 64 bit clients had to be first in the path, and no ORACLE_HOME variable set in the User Variables. BUT, a TNS_ADMIN variable needed to be added pointing to the tnsnames.ora file in the 64 bit client. The error went away.
