I have a Oracle home with 10g client and another with 11g client.
The default one is the 10g.
I have the same tnsnames is both.
If I start SQLNav and I start a session in 11g home
If I then try to start another session it always ask “The connection needs to use a different Oracle Home (…)”
(even If I choose that one as the default oracle_home for SQLNAV)
That question appears even before I choose the connection and (if I use the cancel button) after I choose try tho change the new connection Oracle home to the 11g (it always presents the 10g home by default for the second connection)
