Did anyone ever have any JDBC problems from application servers after a DB server OS upgrade ?
I had an Oracle 19C SE DB server on RHEL 7 with several instances. I have migrated the databases on a new one with RHEL 8, same Oracle 19 SE with the same IP and the same name of the former server. When the application servers tried to connect to it, it failed because of JDBC problems. Does it often occur after a RHEL OS upgrade?
