Inside Oracle's Own Global Operations Data Center

[Oct. 27, 2008 Update:  The latest version of this popular presentation from OpenWorld 2008 is now available for download.  For links to the latest version, see this article.]

Every year at OpenWorld, Bret Fuller discusses how Oracle consolidated over 70 individual E-Business Suite instances into a single instance serving all global operations.  The statistics for Oracle's own Global Single Instance keep rising impressively every year:

Oracle Global Single Instance Statistics:

Bret's presentation this year covers:
  • The business metrics before and after the consolidation
  • Savings estimates and a discussion of business benefits
  • Oracle's Global Single Instance architecture, including a glimpse of the off-site production and disaster-recovery setups in our Austin and Colorado Springs data centers
  • Before and after hardware comparisons
  • Tips on project management best practices
  • Detailed view of the change management processes around the Global Single Instance
  • Critical success factors and tips

Hi, Kevin,Slides 29 to 31 show the detailed logical architectures. Both the production and disaster recovery data centers have RAC-based databases.Regards,Steven

Uh, where is the Linux RAC?

Right, but Larry says Oracle runs their entire business on Linux so I would have expected some large node count cluster of Linux servers. To replace that degree of Starfire gear I should thinkg a 16 node cluster (or so) would be required?

A 6:1 ratio of Sets of books to Operating Units?

Nice blog, Kevin.  You've got a great deal of interesting material there.Our Global Single Instance's middle-tier runs on commodity Linux servers from Dell.Our database servers for the Global Single Instance run on four Sun Solaris 25K SMP servers -- each with 36 x 1.2 GHz CPUs and 144 GB of RAM.Regards,Steven

Fancois,Apparently so.  I don't have much visibility into that side of our operations, so I've passed your question on internally.  I'll post an update here if something comes back on this.Regards,Steven

I think a lot of people would like to know if the 4 node E25K cluster (RAC) is using ASM.

Posted by Kevin Closson on December 04, 2006 at 09:19 AM PST #

Kevin,Our AppsIT group sent me the following reply to your questions:<snip>1) Our environments, GSI included, are currently not configured using ASM.  We however do have plans to use ASM for GSI and other environments.  As such, ASM can be implemented using existing infrastructure.  The additional requirement with ASM is using RMAN for backup which Oracle and the our team does have the expertise but needs to continue building up the infrastructure requirements.2)  [For our database migration to Linux] we will start on this next calendar year as part of migrating a number of databases, including GSI, to Linux.</snip>Regards,Steven

Thanks for the update, Steve

Has Oracle migrated its Global Operations Data Center environment to Linux, if yes what is the current system configuration that replaced the 4 - E25K's?

Thank You

Our internal EBS implementation is still using SMP servers on the database tier. For details, see this latest update to the Applications IT's OpenWorld presentation about EBS 12:
