Is Oracle11g V2 going to have shared-nothing aspects?

One of my favorite DBMS reporters:

  1. Uncovered convincing rumors that Oracle 11g V2, to be announced next week, will have clustering or “grid” enhancements.
  2. Uncovered unconvincing rumors that some of these enhancements will address Oracle’s well-known and problematic lack of shared-nothing capabilities.
  3. Pointed me at a couple of posts that went up and were quickly taken back down from Don Burleson’s site.

More precisely, he pointed me at the Google cache versions of same, which are here and here; obviously, those links will expire at some point.  And so I’m reproducing the key parts below, namely:

These are work in progress excerpts from the book “Oracle 11g New Features” authored by John Garmany, Brian Carr, and V. J. Jain, with Oracle ACE’s Steve Karam and Lutz Hartmann.

Important ASM changes in 11g release 2

There are some super-important changes to storage management in Oracle 11g release 2,  Oracle ACE Lutz Hartmann has offered these excerpts from his new book “Oracle 11g New Features” that delve into these important new enhancements in 11gr2.

ASM Cluster Filesystem (ACFS) – This new feature allows is also named “Unified Storage Management” (UFS) and allows for storing Application File Data , the Oracle Cluster Registry (OCR), the Cluster Voting Disk, and the Oracle Binaries, all within ASM

Cluster Voting Disk and Cluster Registry in ASM – This is an important RAC enhancement where it is now possible to create Quorum Disk Groups and Quorum Disk FailGroups which cannot hold any other data than OCR or Voting Disk data.

ASM Dynamic Volume Manager (ADVM) – ADVM is a new device driver which is integrated into the Oracle Kernel and functions as a standard I/O interface for normal file systems to utilize ASM functionalities.   This driver communicates with the ASM instance about ASM extent maps, rebalancing operations and I/O failure issues.

ASM FS Snapshots in 11gR2 – It is now possible to create up to 63 image copies of file systems as a point in time capture. These snapshots a read only and can be used to view a file system as of the point in time in the past when they were created.

ASM Optimal Disk Placement in 11gR2 – It is now possible to specify on which disk regions the ASM Disks will be placed. This enables us to make use of faster disk zones on the outer regions of disks for better I/O performance.

That all doesn’t sound very shared-nothing-ish to me.

    If one of your favorite DBMS reporters is Don Burleson, that is too bad. He usually gets it wrong.

    Unfortunately Oracle 11g Release 2 will not be released next week at Oracle OpenWorld, so I would check your sources.

    Don Burleson is not a reporter. So that’s not who I meant.

    But thanks for the 11g clarification!
