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) 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

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 Don’t underestimate Oracle (don’t drink our cool aid) MS SQL Server 2008 (coming soon) is real threat Oracle may have to adjust to compete (lower price) 3

21 Flash Back Transaction 21 SQL> select xid, start_scn, operation, table_name, undo_sql from flashback_transaction_query where start_timestamp>=sysdate-1 and username='BERT' and table_owner='BERT'; XID START_SCN OPERATION TABLE_NAME UNDO_SQL DELETE JUNK insert into "BERT"."JUNK"("C1","C2") values ('5','6'); DELETE JUNK insert into "BERT"."JUNK"("C1","C2") values ('3','4'); INSERT JUNK delete from "BERT"."JUNK" where ROWID = 'AAAD94AAAAAAChOAAD'; INSERT JUNK delete from "BERT"."JUNK" where ROWID = 'AAAD94AAAAAAChOAAC'; INSERT JUNK delete from "BERT"."JUNK" where ROWID = 'AAAD94AAAAAAChOAAB'; INSERT JUNK delete from "BERT"."JUNK" where ROWID = 'AAAD94AAAAAAChOAAA'; SQL> select * from bert.junk; C1 C SQL> declare trans_arr XID_ARRAY; begin trans_arr := xid_array(' ',' '); dbms_flashback.transaction_backout (numtxns => 1, xids => trans_arr, options => dbms_flashback.cascade); end; / SQL> select * from bert.junk; C1 C

22 Flash Back Data Archive 22 SQL> create tablespace flash_archive datafile '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 time that it would be flushed out of the UNDO tablespace. Therefore, it’s 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.
