our remote server has oracle 8 and Oracle 10G. Oracle 8 installs very long before and oracle 10G installs today.
As sql developer cannot support to 8i; when i try to connect to oracle 10G i get the following error. ORA-12505
I have oracle in my laptop and can connect via sqlplus but cannot connect with sql developer.
C:\>sqlplus sys as firstname.lastname@example.org:1521/xxxx
