UKOUG Tech14 Slides: Testing Jumbo Frames for RAC

Just a quick post to link to the slides from my presentation at the UKOUG Tech14 conference. The slides do not appear to be visible on the Super Sunday site, hence this post. The presentation was called “Testing Jumbo Frames for RAC”, the emphasis as much on the testing as on Jumbo Frames.


A discussion on the usage of Jumbo Frames for the RAC interconnect. We’ll cover background information and how this can be tested at the Oracle level and in the Operating system. We’ll also discuss how testing initially failed and why it’s interesting.

This is a topic that enters the realm of network and Unix admin’s but the presentation is aimed at DBAs who want to know more and want to know how to use Operating System tools to investigate further.



The conference itself was another success with particular highlights for me being James Morle talking about SAN replication vs DataGuard, Ludovico Caldara talking about PDBs with MAA, Richard Foote because I was like a silly little fanboi and Bryn Llewellyn purely for the way he weaves the English language in to something beautiful on the ears. All of my programs will have “prologues” and “epilogues” from now on, “headers” and “footers” are so passe 🙂

Equal to the presentations was the social side of things too. I do enjoy hanging around in pubs and talking shop.
