AWR Warehouse

I just noticed last week that there is a new patch for Enterprise Manager and it is enabling AWR Warehouse feature. There is a note ID 1901202.1 which describe bundle patch for OEM 12c release 4.

Today I had a chance to install it in my lab and now I can start testing new OEM feature.
There is some documentation here and on Kellyn's blog.

SLOB Physical I/O Randomness. How Random Is Random? Random!

I recently read a blog post by Kyle Hailey regarding some lack of randomness he detected in the Orion I/O generator tool. Feel free to read Kyle’s post but in short he used dtrace to detect Orion was obliterating a very dense subset of the 96GB file Orion was accessing.

Crossplatform transportable tablespaces - part 2

It took some time since I wrote a first post about TTS migration but I finished that project literally hours before my summer break. Now after couple of days while I enjoyed thermal waters and good wine of Hungary it's time to write next post.

As I described in my previous post I had to migrate database from HP-UX into Linux and also upgrade it from 10g into 12c. This time it was only PoC but my goal was to minimize downtime of production database.

ALS (No) Ice Bucket Challenge

Ronald Vargas challenged me to the ALS Ice Bucket Challenge. Unfortunately we didn’t have any ice, but the water was cold anyway, as you can see by my reaction at the end. :)

I challenge Debra Lilley, Graham Wood and Heli Helskyaho.

Please don’t forget to donate!

Cheers

Why I like the term “Research Lab”

I love the term “Research Lab” to refer to our collection of Oracle Engineered Systems. It’s because that’s what we do with the equipment. We test it, we try weird experiments with it, we take it apart with a screw driver and we put it back together again. And lot’s of times we break things. But better that we break them in the lab than on a production system at a client site. The lab is a great learning environment for us and our customers. Enkitec has had a pretty solid lab for a while, but it’s about to get a lot bigger.

Here’s an abbreviated list of the what we expect to end up with in the lab in the next few weeks.

Lucy

I’ve had a day off today, so as well as swimming, starting to clear out my junk room and going to the pub to say “see ya” to a colleague who is going on maternity leave, I went to see Lucy.

Let me start by saying this is pretty much a rip-off of Akira. Not in a word-for-word copy sense, but it’s like Luc Besson watched Akira and said, “How and I take most of the main points, while trying to make it seem like I’ve written something new, but still steal a bunch of the visuals?” He then went to sleep, woke up and wrote Lucy.

Altering Hosting Service : The Gift That Keeps Giving

I moved my website to a new dedicated server about 3 weeks ago. As well as the usual DNS nonsense, I found out today that a whole load of emails have been blocked…

I have a mailbox at the hosting company to handle all my email. That all gets sucked into Gmail. That’s the way it has been for ages and life has been good. Since I made the move, the “new” mailbox looked like it was working fine, but I hadn’t noticed the spam filtering was turned on to a really high level and it was blocking loads of good emails. As a result, a lot of really important emails were gathering in the spam folder of my mailbox at the hosting company, something I never check.

I’ve now turned off the spam filtering on that mailbox, so it all gets sucked into Gmail and that handles my spam, the way it always did…
