Reset Oracle credentials
Ok, you're going to have to excuse my ignorance here. I'm no systems developer/web developer/programmer of any kind. But I hope someone here is kind enough to help me solve the situation I am in.
I have a Droplet (SFO2 - CentOS 6.9 x64) that has Oracle installed for an Apex DB. The developer who installed Oracle has now disappeared and left me without access to Oracle itself. He gave me several sets of usernames and passwords, but it seems this one is missing. So my question is: how can we reset the Oracle credentials? We can log in to the console but can't get access to Oracle.
I apologise upfront if I've used the wrong terminology.
