"The changes to RAC (Real Application Clusters) and the grid as a whole are very exciting," wrote 'Grumpy DBA' blogger Jay Caviness in July, in an entry that was deleted sometime after mid-August. Caviness, in an e-mail today, said Oracle asked him to take down the post, saying he was bound by a confidentiality agreement and could not comment until the official announcement of 11g R2 database.
Clustering and storage management
There's more concrete evidence, however, for improvements in the narrower area of how 11g R2 physically stores data.
According to a presentation last year by Oracle vice president for database product management, Mark Townsend, 11g R2 will include the ability for "plug and play clustering." That means the ability to quickly bring additional servers or hard disks online without needing to rewrite, reboot, or load balance.
According to information posted by Oracle service provider, Burleson Consulting, "there are some super-important changes to storage management in Oracle 11g release 2."
The new features in Oracle's ASM (Automatic Storage Management), include the ability to take snapshots of data for backup purposes, rebalance I/O, place data in faster parts of the disk, and unify the storage management, according to Burleson.
The Web pages on ASM were deleted sometime after Sept. 4. Oracle did not contact Burleson Consulting to remove them, according to Robin Rademacher, operations manager at Burleson Consulting, nor did the firm remove them because they were inaccurate.
"We knew they weren't supposed to be published yet, that's why we took them down," she said via phone today. "We built them as placeholders knowing that R2 would be coming at OpenWorld."
Oracle officials are also scheduled to discuss a "new database accelerator" during three OpenWorld sessions Sept. 25, as well as in a separately titled technical overview session later that day.
The frequency "sort of implies that we're talking about an actual new product here rather than just a marketing exercise," wrote Mark Rittman of Rittman Mead Consulting, a U.K. Oracle data warehousing and BI (business intelligence) specialist, on his blog.
