ANNOUNCEMENT: community.oracle.com is currently Read only due to planned upgrade until 29-Sep-2020 9:30 AM Pacific Time. Any changes made during Read only mode will be lost and will need to be re-entered when the application is back read/write.
In opening an existing connection in R3.2, I discovered that the password had changed. I then changed the password. I returned to R4 and changed the password for the connection and attempted to test it. I got the following error message:
Status: Failure - Test failed:oracle.jdbc.drive.T2CConnection.getLibraryVersionNumber()I
I get the same oracle jdbc error when I save the change and attempt to open the connection. I have retyped the password multiple times, and still get this error. In earlier versions, an incorrectly typed password produced a different error message.
The connection type (TNS) had switched from NETWORK ALIAS to CONNECT IDENTIFIER without my intending it. When I switched it back, the connection test worked.
