[...] I went to Oracle in October, the main purpose of the visit was to discuss Exadata. And so my initial post based on the visit was focused accordingly. But there were a number of other interesting points I’ve never [...]

Kevin,

Juan was probably there for the shortest stretch of time, possibly excepting Vishu Krishnamurthy, who was only invited when it became clear there would be time to talk about something besides data warehousing. I.e., Juan didn’t sit and stay much except during his actual presentation. So he wasn’t there around the end.

Ray Roccaforte and Gordon Smith are the ones who stayed pretty much all the way through. Andy was in and out. I’d guess Cetin stayed longer overall than Juan did.

Mark Townsend, who was originally tasked with setting up the visit before delegating that to Gordon, wasn’t there at all.

Curt,

That is funny because Juan recruited me and has known me for 18 years (joint engineering with between Sequent and Oracle) and is my bosses-boss…funny.

Juan has bought into the value of blogs. I’m glad to see Andy joining in.

Kevin,

That was my sense too.

An attempt was made to locate you toward the end, whereupon it was discovered that you don’t live in the area or work at HQ.

Based on a couple of remarks, and some follow-up discussion, it seems safe to say that you and I together have helped educate Andy Mendelsohn on the influence of blogs.

Hi Curt,

Yes, Oracle Parallel Server (OPS) is in fact a prior release of RAC. It was re-branded when Cache Fusion was implemented (circa Oracle9i). Actually, Oracle8i R3 (8.1.7) had little bits of Cache Fusion in it too (for certain types of cross-instance reads). Trivial pursuit I suppose.

Thanks for the typo tip.

PS. I heard your visit at Oracle HQ went well.

Thanks for the clarification Kevin … but what is Oracle Parallel Server? Simply the predecessor to RAC?
PS. In other news, you have an is/his typo that needs fixing in a short recent post on your blog.

Real Application Clusters and Oracle Parallel Server alike require a Distributed Lock Manager. Since Oracle8 Parallel Server, the DLM has been provided by Oracle. Prior to that it was provided by the host platform vendors.
