Oracle Developer Day Perth

Well…it was a great day with over 100 people attending.

I had the standard fail of trying to show people 200 things that I think are important, in a time allowing only for 50 things, but better to be overfed than starving :-)

Links to the slides are below.  Thanks everyone for coming – hope you had a great day.

Lineage of the 100-400 slide PPT

There is the  Mandel approach to power points in presentations where one is suppose to spend 3 minutes per slide, thus a 60 minute presentation is 20 slides or less.

How about going the other way, showing 3 or more slides per minute?

RMOUG Training Days 2014

I made my way again this year to one of the best, if not the best, user group conferences, the Rocky Mountain Oracle User Group Training Days, held in Denver Colorado on the 6th and 7th of February. Huge kudos to Kellyn Pot’Vin and the rest of the organizing team (see her review here) for […]

Full free day of performance class at Oracle Corp

This Thursday, Feb 20, I will be giving a full day of free Oracle performance classes.  Remember the serve the best lunch ever at the Oracle conference center . It’s top class!

Here is the write-up from NoCOUG on the day:

11.2.0.4 Upgrade

A warning on Oracle-L from Chris Dunscombe: If you’ve got a large stats history – with lots of histogram data – then the upgrade could take an unexpectedly long time. Presumably the same is true if you upgrade from 11.2.0.3 (or earlier) to 12c.

 

Oracle 12c Edition-Based Redefinition (EBR)

Oracle 12c has many great features for DBAs and Developers; I’ll be talking about more features 12c in future articles (watch this space).

Edition-Based Redefinition made its debut in Oracle 11g and provides an ability to significantly reduce downtime due to changes in PL/SQL and/or SQL. Oracle 12c removes some limitations present in 11gR2 implementation of EBR:

  • Materialized Views may use editioned resources
  • Virtual Columns may be used with editioned functions

Materialized Views are not-editionable; but, Oracle 12c allows them to depend upon editioned objects with a new clause and new syntax for ENABLE QUERY REWRITE. The EVALUATE USING clause indicates that a referenced object is editioned (editioned objects are invisible otherwise). ENABLE QUERY REWRITE may be limited to selected editions. The new Materialized View CREATE/ALTER syntax looks something like this:

I’m off on for a couple weeks for paternity leave! Actually started on Saturday night a week ago with the beautiful, stressful, exciting, fast birth of our second son. What a gift. :)

Fedora 20 : Upgrade from Fedora 19

It’s a little over a month since Fedora 20 was released, but during a terrible bout of insomnia last night I decided to upgrade my desktop PC.

The upgrades using “fedup” worked fine for the previous releases (Fedora 18, Fedora 19). Unfortunately, it failed abysmally for the upgrade to Fedora 20. I tried a few times, but I was not able to troubleshoot it, so I gave up and did a reinstall.

I’ve got an SSD for the system drive, but keep almost everything of importance on a second drive (and a backup drive). I tend to do most things in VMs, so I ended up doing the following:
