Memory Pressure Analysis Risk State

I have a Test database that is a 2-node RAC system. I am working towards the goal of getting the production database to Oracle in about a month’s timeframe. This of course means that I have to get Grid Infrastructure upgraded prior to the db upgrade. I have upgraded GI on my standby cluster and on my Test database as well.

A few of these standard tweaks have been put into the repvfy execute optimize command.    You can make all these changes individually, but if you want to get them all done at once, optimize is your tool.
