New Slide Decks Uploaded:
Upgrade/Migrate/Consolidate to Oracle 12c and
Parallel Multitenant Upgrade Internals

It's time for a few updates and slide uploads :-) And thanks again to all the great people in Madrid earlier this week. It was a fantastic day - I enjoyed it a lot and wish you all successful upgrades and migrations :-)

What's new? 

  • A refreshed version of our huge Oracle Database 12c "Upgrade, Migrate & Consilidate" slide deck. Now with 530 slides - kudos to Tom Kyte who gave me a lot of food for thought after his excellent talk at the DB TECH SHOWCASE 2014 TOKYO. I had to add a few slides later on making it now even harder to fit the content into a 1 day workshop :-)
    As usual see the Change Log at the end of the deck about what has been added/changed.
  • A new and extended version of Joe Errede's OOW talk about how an Oracle Multitenant Upgrade works. All details about the parallel upgrade, options and tweaks of catctl.pl. So kudos to Joe as he has build the basis for the slides - I reused many of them and added some stuff - and thanks to the (always) great audience at DOAG Conference in Nuernberg :-)
  •  A refreshed version of the Hitchhiker's Guide especially prepared for the (amazingly) huge audience at the DOAG Conference in Nuernberg (I was really impressed!!)

How to SET TIMING ON for parallel upgrades to 12c?

Have you asked yourself how to get timings in an Oracle Database 12c upgrade for all statements?

When you run the parallel upgrade via catctl.pl, the parallel upgrade Perl driving script in Oracle Database 12c, you may also want to get timings written in your logfile during execution. As catctl.pl does not offer an option yet the best way to achieve this is to edit the catupses.sql script in $ORACLE/rdbms/admin as this script will get called all time over and over again throughout all steps of theupgrade run.

Just add these lines marked in RED to catupses.sql and start your upgrade:

Rem =============================================
Rem Call Common session settings
Rem =============================================
@@catpses.sql

Rem =============================================
Rem  Set Timing On during the Upgrade
Rem =============================================
SET TIMING ON;

Rem =============================================
Rem Turn off PL/SQL event used by APPS
Rem =============================================
ALTER SESSION SET EVENTS='10933 trace name context off'
;
