SP2-0750: You may need to set ORACLE_HOME to your Oracle software directory


"SP2-0750: You may need to set ORACLE_HOME to your Oracle software directory" clearly indicates that you are missing one of your major Environment Variables in order to get connected to the Oracle. The Environment Variables should be properly defined in bash_profile (in Linux) or profile (in Unix) to avoid such issues.

But still if you want to continue without making the entries in the bash_profile or profile, just set the variables on terminal or Command Windows and continue. After setting the correct Environment Variables, SQLPLUS connectivity to Oracle Database will be successfully done.
