Great to be able to have some contribution to Oracle Community!! Mike is a Master Product Manager – Database Upgrade & Migrations at Oracle. He is an Oracle GURU in a scope of database upgrades.

Mike Dietrich mentioned me to have given him some info regarding insights on one of 2c hidden parameters https://blogs.oracle.com/UPGRADE/entry/gc_rac_issues_12_1. It really made my day!!

Thank you Mike!
