I have an interesting problem. I've developed a client/server application at Uni. of Maryland that is used at 12 of our campuses across the state. The app is written in PB10.5 and has been run against an Oracle 9i db. Recently we upgraded to Oracle 11 and I've had to add two new users at different campuses. Here's the interesting problem. Once I've loaded the deployment libs and PB application, loaded Oracle 8.7 client - to get the odbc for Oracle - and wrapped up the install, I always log in to see that the application works for the user. Afterward I create the new user from sqlplus and send the user/pass to my new user. But they can't log in using the new user/pass from the newly set up computer. They can log in from an earlier set up on an older machine. These new machines are Dell running windows xp and nothing seems out of the ordinary. It's just weird that any user created before the Oracle 11 upgrade can log on these new machines, but new users can't, but they can log on machines set up prior to the O11 upgrade. Has anyone seen this kind of behavior?
