[Oracle] DB Optimizer Part XII - Revealing SQL Plan Directive details for existing/loaded cursor from CBO (and SQL Dynamic Sampling Services) trace

Introduction

The idea for this blog post is based on a recent Twitter discussion with Martin Berger, Martin Bach and Mauro Pagano about revealing SQL Plan Directive details for an existing cursor as walking through the standard Oracle data dictionary views can be very time consuming/slow and there are still some details missing about the dynamic sampling task itself, even if you have found what you are looking for.

 

Friday Philosophy – Friday Afternoon Phone

{<}

Update on my trip to the Apple Store >>}

There used to be a phrase in the car industry in the UK (I don’t know about elsewhere) a “Friday Afternoon Car“. This is a car which is unusually unreliable, as it was built on Friday afternoon when the workers were tired, the weekend was coming and, heck, they might have been to the pub at lunch. It is occasionally used just to describe something that is a bit crap and unreliable.

Old ventures and new adventures

I have some news, two items actually.
First, today (it’s still 18th June in California) is my blog’s 8th anniversary!
I wrote my first blog post, about Advanced Oracle Troubleshooting, exactly 8 years ago, on 18th June 2007 and have written 229 blog posts since. I had started writing and accumulating my TPT script collection a couple of years earlier and now it has over 1000 files in it! And no, I don’t remember what all of them do and even why I had written them.

Thanks everyone for your support, reading, commenting and the ideas we’ve exchanged over all these years, it’s been awesome to learn something new every single day!

New Monitor… Again…

220px-Commodore_PET2001I’ve just bought myself a Dell U3415W 34-Inch IPS LCD Monitor for use with the laptop. It’s quite an extravagant purchase, but it’s pretty amazing. Having 3440×1440 resolution on a single screen feels much more useful than sitting a couple of smaller monitors next to each other. It feels almost like having 3-4 screens in one.

I bought it to replace the Asus PB298Q 29 inch Widescreen AH-IPS Multimedia Monitor I got about 7 months ago. The resolution of 2560×1080 is pretty darn decent, but I don’t like having a depth of 1080. When you are using a wider screen, the limited height feels really restrictive for some reason.

12.1.0.5 Hybrid Cloud Cloning

Last week’s release of 12.1.0.5 was a pleasant surprise for everyone out in the Oracle world.  This release hit the bulls-eye for another cloud target of Oracle’s, announcing the introduction of Enterprise Manager 12c’s offering a single pane of glass management of the hybrid cloud.
