Additional Core addition R12.2 RAC

[satish]

Dear erman,

We have 2 node rac DB
version 12.1.0.2

Erpdb1 2 core
Erpdb2 2 core

Erpapp01 2 core
Erpapp02 2 core

We are planning to add additional 2 cores to each DB server, so they become 4 core.

Do we need any additional licence for this.?

Thank you
