Initial Database creation in X4-2

Hello,

We are creating our first database in ODAX4-2(12.1.2.3) and would like to know couple of things.

- Is oakcli create database is the preferred way to create the db

- How and where should we specify the template/classes name, for eg:odb-02

- If we specify odb-02, does it assign 2 core by default

- How does the core licence work on ODA? Can we create multiple databases as long as we assign the licenced core to ODA_BASE?

Thanks in advance.
