I have an instance of "Oracle Express XE 18" loaded on a desktop.
Using this desktop -
I am able to connect to that XE with Oracle Developer, SQL+ and Toad - proving the validity of my tnsnames.ora and authentication protocols
I am NOT able to connect to that XE with PowerBuilder. When I attempt a connection I get error message: oerr ORA 28040 "No matching authentication protocol". PowerBuilder is able to connect to other external server resident Oracle databases, but not the local desktop resident Oracle Express XE.
Other likely pertinent information:
1. I have been using PowerBuilder for 20 years but recently upgrade to Appeon's version in order to migrate to Win10.
2. This is the first time PowerBuilder has been loaded on this particular desktop.
3. This is the first time I have tried to connect PowerBuilder to an Oracle Express instance
Is there some trick to connecting to an Oracle Express?
