Agenda

This is mean to be more of an open discussion

No set time per topic - each topic has just enoughinfo 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 soon2


3/50

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)

Flash Back Data Archive

22

SQL> create tablespace flash_archivedatafile 'c:\oracle\oradata\ordb1\flash_archive.dbf' size 50M;

Tablespace created

SQL> create flashback archive default flash_archive tablespace flash_archive retention 30 day;

Flashback archive created.

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 timethat 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 retainedtransaction history can be viewed, and this eliminates thecumbersome task of creating corresponding history tracking tables

for critical transactional tables.
