 1. For optimal performance, configure system with expected number
 of pages for every supported system pagesize prior to the next
 instance restart operation.
Sat Oct 28 18:48:39 2017
 2. Increase per process memlock (soft) limit to at least 30GB
 to lock 100% of SHARED GLOBAL AREA (SGA) pages into physical memory
