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.
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:
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).
If you are using Oracle Database Appliance (ODA) then this patch is very important to apply. The patch bundle 18.104.22.168.0 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 [...]

Ok, it’s official – the first and only Oracle Troubleshooting TV show is live now!
The first show is almost 2 hours about the ORA-4031 errors and shared pool hacking. It’s a recording of the US/EMEA timezone online hacking session I did some days ago.
There are a couple of things to note:

Video is awesome. I like high-bandwidth communication. Even on the cheapest, most un-produced videos, I can see facial expressions and body language that I'd never be able to pick up from text. I can see candidness that's not going to come through in a document, even a blog that's written pretty much off the cuff. And videos with high production value, ...well of course it's awesome to watch a great short movie right at the tips of your fingers.
But when you send me a 7:48 video, I have to budget 7:48 to watch it. (Well, more actually, because of the latency required to buffer it up.) When you send me a 13-page document, I can "read" it in 10 seconds if I want to. I can skim the first and final paragraphs really quickly and look for pictures or sidebars or quotes, and it takes practically no time for me to do it.
With a video, it's just more difficult to do that. I can watch the first 10 seconds and usually know whether I want to watch the remainder. But skimming through the whole video—like skipping to the end—is more difficult, because I have to sit there un-utilized while the whole video buffers up. Then I have to sit there while words come at me aurally, which is annoyingly sequential compared to reading buckets of text in one eyeful.
So, the bottom line is that the first 10 seconds of your video need to convince me to watch the remainder.
Or I won't.
Is it just me?
