I am not that zero knowledge on oracle as I have attend Oracle 11g workshop, and also have more and more knowledge of Oracle like topology and theory as well as weakness of Oracle. I DO NOT have hands on setting up RAC, dataguard, ASM and replication on Oracle,.
Now I want to get Oracle OCP, for example, for 19c, any kind of resource/URL/video/book you oracle expertise can suggest me to read to pass OCP as easy as possible ?
12c, 18c and 19c is the version of focus.
I prefer online video training, as it is easier for me.
how about the same thing for MySQL ? I want to get OCP for MySQL too and I have a lot of hands on experience on MySQL , like replication, InnodB cluster , but NOT NDB cluster yet!
