Personally I would lean toward following 278641.1. Document 813445.1 states clearly: *"This document is being delivered to you via Oracle Support's Rapid Visibility<https://support.oracle.com/CSP/main/article?cmd=show&type=NOT&doctype=HOWTO&id=813445.1#>(RaV) process, and therefore has not been subject to an independent technical review." * No such disclaimer found in docid 278641.1 and this document looks comprehensive, includes references and was last updated/published June 2010. The other document was last updated April 2009. If in doubt contact support before applying to confirm the correct order. That's my .02, Brent On Tue, Jul 27, 2010 at 7:35 AM, Ray Stell <stellr@xxxxxxxxxx> wrote: > 813445.1 says to apply cpu to primary first. > 278641.1 says to apply cpu to standby first. > Maybe it doesn't matter.
