uninstall Oracle 12c from system

Question

I am not expert at oracle database, i was using the oracle server but now I wanted to remove that. So for removing the oracle server I have deleted the installation folder instead of using the oracle de-installer. But I can see some services in my system. Can some one please help me to remove those configurations as well. Please excuse my silly mistake.

Answer 1

That's not really Oracle problem any more, but Windows operating system's.

As you already are in "Services", double-click its name to see both

• service name
• display name

as sometimes they differ. Then open Windows' command prompt and run

sc delete "OracleJobSchedulerORCL"

where OracleJobSchedulerORCL is the service name . Double quotes aren't needed if there are no spaces in the service name.

If successful, you'll see the

[SC] DeleteService SUCCESS

message.
