2008 Quest Software, Inc. ALL RIGHTS RESERVED. Oracle 11g R1 Top Features for Developers & DBAs August 2008 Slide 2 Agenda This is mean to be more of an open discussion No set time per topic - each topic has just enough info to spur questions and/or open a dialog so talk Feel free to ask questions about other topics No cell phones with ringer turned on (use vibrate) Email only during breaks under penalty of death 11g adoption may have been slow but: 11g R1 is now over one year old 11G R2 beta will be starting soon 2 Slide 3 Focus 11g has huge growth in functionality (install size, resource consumption, time to create database, etc) Too many features to cover them all in few hours!!! Will concentrate on key ones you may encounter Dont underestimate Oracle (dont drink our cool aid) MS SQL Server 2008 (coming soon) is real threat Oracle may have to adjust to compete (lower price) 3 Slide 4 Oracle vs. Toad Timeline Oct 98 v5 Initial Quest release.

SQL> create table bert.junk (c1 int, c2 int) flashback archive flash_archive; Table created. This new feature offers the ability to retain the reciprocal UNDO information for critical data significantly beyond the point in time that it would be flushed out of the UNDO tablespace. Therefore, its now possible to hold onto these reciprocal transactions essentially indefinitely. Once this feature is enabled, all retained transaction history can be viewed, and this eliminates the cumbersome task of creating corresponding history tracking tables for critical transactional tables.
