Sorry for the delay in getting this posted, but thanks to everyone who attended my November 12th webinar entitled In Search of Plan Stability - Part 2. You can download the presentation materials from these links:
I made a short post over at ToadWorld about bringing my nephew to my office in Dallas this week for a Young Programmer's camp. He had a great time as far as I could gauge the excitement of a 16 year old boy (errrrrr....young man)! He rocked it out creating several different game knock-offs and got a feel for what it would be like to be a software developer. Fun stuff!
In order to help me stick to my commitment to blog more regularly, I've joined the blogging community at Toad World. I'll link to most posts from there as I make them (I love knocking down two targets with one arrow) and keep on track for at least one post a week moving forward. Yea!
You can read my brief hello over at Toad World here. Stay tuned in the weeks ahead for a series of posts on Oracle performance, SQL and the optimizer. I'm going to start with a few posts on code instrumentation and move on to cover many of the suggested topics I received from you all.
I've decided to get back in the groove of making more regular blog posts and have an intention to blog at least once a week in the coming months to get myself back in the habit. While I always seem to have a head full of stuff that never makes it to the blog, I thought I'd ask you all if you have any topic suggestions?
At this point in time, I'm not sure anyone drops by here much since my posts have been mainly announcing webinars and providing follow-ups. But, I figured I'd put it out there and see if anyone still has their ears on. :) So, if you've got something you'd like to hear about, leave me a comment and I'll see if I can supply something suitable.
If I don't get any suggestions, I'll just ramble on what happens to be in the front of my brain at the moment. :)
Thanks to everyone for attending today's Writing SQL Right webinar sponsored by Embarcadero. For attendees, Embarcadero will send out a link via email to the recording and PDF of the presentation, but I also wanted to post it here.
Coming up on May 20, I'll be delivering a webinar entitled Oracle SQL Performance: Writing SQL Right. Registration is now open. Once again the webinar will be hosted by Embarcadero and there will be two sessions - one at 10am ET and one at 2pm ET.
There are many ways to write a SQL statement that may lead to the functionally correct answer. However, we often get stuck in a rut using the same SQL syntax over and over even when there may be a better way to write the SQL to enhance performance.
Some techniques worked great in previous Oracle versions but changes in the optimizer with the later versions made the behavior of those techniques change and, in many cases, regress.
This session covers a number of common anti-patterns that can be rewritten to provide enhanced performance and will help you learn how to:
Recognize certain patterns that can be sub-optimal.
Analyze the "performance footprint" of certain patterns.
Rewrite the anti-patterns to use less resources and take less time to execute.
Thanks to everyone for attending today's Effective Indexing webinar sponsored by IOUG with Embarcadero. For attendees, IOUG will likely send out a link to the recording and PDF of the presentation, but I also wanted to post it here.
Please note that during the webinar I mentioned the new clustering factor calculation available in 12c and also available in some patchsets for 11g releases. The patch number I referred to is incorrect. Instead, please search for the Bug/Enhancement article in MOS. You can find it by searching for "Bug 13262857 - Enh: provide some control over DBMS_STATS index clustering factor computation (Doc ID 13262857.8)."
Thanks again and stay tuned for additional webinars coming soon!
