i have installed the software in my laptop in the path i mentioned below, you also see the path where you have installed it. if at all didn't find any path, remove it and re-install carefully, i that process remember where your installing it. go to this path on your computer where oracle is installled. F:\app\SVS\product\12.1.0\dbhome_1\NETWORK\ADMIN 1.check listener.ora and tnsnames.ora to verify portnumber and hostname 2.check whether lsnrctl is sleeping. if so, make it start. 3.if you are fine with above steps and even showing the errors. finally check your input for user and password is valid. select service name & type orcl and press connect button. thank you.
