Video : The MERGE Statement

After a what seems like an eternity of being ill and having a dodgy throat, followed quickly by a couple of conferences, I’ve finally got back on the horse and recorded another video.

I was explaining a specific aspect of the MERGE statement to one of my colleagues and while I was doing it I was thinking, “Have I done a video on MERGE yet?” Now I have.

The cameo for this video is Cary Millsap. If you watch the out-takes at the end you will see the level of respect and trust I have garnered in the community. The words confused and suspicious spring to mind! :)

Video: Amazon Web Services (AWS) : Relational Database Services (RDS) for SQL Server

Here’s another video on my YouTube channel. This one is a quick run through of RDS for SQL Server, a DBaaS offering from Amazon Web Services.

The video was based on this article.

The cameo for this video is Garth Harbach, a former colleague of mine. :)

Video: Amazon Web Services (AWS) : Relational Database Services (RDS) for MySQL

Here’s another video on my YouTube channel. This one is a quick run through of RDS for MySQL, a DBaaS offering from Amazon Web Services.

The video was based on this article.

If you watch the little outtake at the end you will hear me cracking up with the goofiest while filming Brian ‘Bex’ Huff‘s clip. :)

Cheers

Video: Amazon Web Services (AWS) : Relational Database Services (RDS) for Oracle

Here’s the latest video on my YouTube channel. This one is a quick run through of RDS for Oracle, a DBaaS offering from Amazon Web Services.

If you are not into the video thing, you can see the article this video was based on here.

Galo Balda has now joined the illustrious list of people who have said “.com” on one of my videos. :)

Video: Database as a Service (DBaaS) on Oracle Cloud

The latest video on my YouTube Channel is a run through of using the Database as a Service (DBaaS) offering on Oracle Cloud.

There have been a few minor changes in the interface since I last ran through capturing images, so the related article has been brought up to date.

I used my dad for the cameo in this video. Hopefully this will help him get a little more recognition, as he’s pretty much a nobody on the Oracle scene at the moment. With your help this could change!

And now, ...the video

First, I want to thank everyone who responded to my prior blog post and its accompanying survey, where I asked when video is better than a paper. As I mentioned already in the comment section for that blog post, the results were loud and clear: 53.9% of respondents indicated that they’d prefer reading a paper, and 46.1% indicated that they’d prefer watching a video. Basically a clean 50/50 split.

The comments suggested that people have a lower threshold for “polish” with a video than with a paper, so one of the ideas to which I’ve needed to modify my thinking is to just create decent videos and publish them without expending a lot of effort in editing.

But how?

When is Video Better?

Ok, I’m stuck, and I need your help.

At my company, we sell software tools that help Oracle application developers and database administrators see exactly where their code spends their users’ time. I want to publish better information at our web page that will allow people who are interested to learn more about our software, and that will allow people who don’t even realize we exist to discover what we have. My theory is that the more people who understand exactly what we have, the more customers we’ll get, and we have some evidence that bears that out.

I’ve gotten so much help from YouTube in various of my endeavors that I’ve formed the grand idea in my head:

All about RAC and MTU with a video

Let’s first discuss how RAC traffic works before continuing. Environment for the discussion is: 2 node cluster with 8K database block size, UDP protocol is used for cache fusion. (BTW, UDP and RDS protocols are supported in UNIX platform; whereas Windows uses TCP protocol).

UDP protocol, fragmentation, and assembly

UDP Protocol is an higher level protocol stack, and it is implemented over IP Protocol ( UDP/IP). Cache Fusion uses UDP protocol to send packets over the wire (Exadata uses RDS protocol though).

Oracle Database Appliance (ODA) Patch Bundle 2.1.0.3.0 Fixes CPU Performance Issue

If you are using Oracle Database Appliance (ODA) then this patch is very important to apply. The patch bundle 2.1.0.3.0 has been published just this week and the most important fix from my perspective is the new BIOS version 12010304. Intel CPUs have a feature called Software Controlled Clock Modulation that allows programmatically control of [...]
