Hello,

By referring this note 1915302 - Database Software 12.1.0.2 Installation on Windows, I can start the database now.

Read/Modify access has been given to the Oracle folders for the Oracle user(It should not be an admin user and it should not be same as the Installation user), which is clearly explained in the above said note.

But now am facing another issue which is shown below,

SAPINST ORACLE start logging for

STARTUP;

exit;

Output of SQL executing program:

Please advice.
