Obvious But Not For Oracle Obviously

While dropping RAC database, I found error ORA-01081: cannot start already-running ORACLE – shut it down first from dbca log.

Looking up error: Cause is obvious

$ oerr ora 01081
01081, 00000, "cannot start already-running ORACLE - shut it down first"
// *Cause:  Obvious
// *Action:

Here is the process for 12.1.0:

Too Old To Remember

Is it required to run datapatch after creating database?

Why bother trying to remember versus running datapatch -prereq to find out?
