Hey guys im a beginner when dealing with oracle and sqlplus and i keep getting this error "ORA-12560: TNS:protocol adapter error" when i try to connect to oracle 12c database with sqlplus.Ive spent over 8 hours trying to fix this and after scouting most of the forum i decided to post because i havent a clue what to do now
Even with i input sys as sysdba i get this error.I made sure and took down all the usernames and passwords i had to when installing but still it seems to give this error.
I also tried starting all the oracle services but to no avail.
I have installed Oracle 12c and oracle developer suite on windows 10 64bit
Anyhelp is appreciated .
