I have a PowerBuilder application that was converted from SAP 12.5 to Appeon 2019 R3 using an Oracle database. We have recently migrated the Oracle database from 12c to 19c. We have a Citrix server the application runs on that has numerous versions of Oracle installed with the 19C as the latest installation. The path has been modified to have the 19C client_1 t the top of the path but when the application runs it does not utilize this path, is there some reason the application is not using this path. Is the pbora.dll expecting a different version of Oracle? Is it not going to utilize the Oracle 19C software?
