Spectre and Meltdown on Oracle Public Cloud UEK – LIO

In the last post I published the strange results I had when testing physical I/O with the latest Spectre and Meltdown patches. There is the logical I/O with SLOB cached reads.

Spectre/Meltdown on Oracle Public Cloud UEK – PIO

The Spectre and Meltdown is now in the latest Oracle UEK kernel, after updating it with ‘yum update':

[opc@PTI ~]$ rpm -q --changelog kernel-uek
| awk '/CVE-2017-5715|CVE-2017-5753|CVE-2017-5754/{print $NF}' | sort | uniq -c
43 {CVE-2017-5715}
16 {CVE-2017-5753}
71 {CVE-2017-5754}

As I did on the previous post on AWS, I’ve run quick tests on the Oracle Public Cloud.

Physical reads

I’ve run some SLOB I/O reads with the patches, as well sit KPTI disabled, and with KPTI, IBRS and IBPB disabled.

And I was quite surprised by the result:

Content- My Year in Review, 2017

So where did 2017 go?!?!?  I really, really would like to know…  Needless to say, it’s time to do a year in review already and I actually have time to do it this year!

DBAKevlar Blog

I wrote over 100 blog posts this year between DBAKevlar, Delphix and partner sites, but I’ve enjoyed sharing with the different communities.  There’s significant changes going on in the IT world regarding the future of the Database Administrator.

Shooting the DBA isn’t a Silver Bullet to the Cloud

We’ve all been watching numerous companies view value in bypassing the Database Administrator and other critical IT roles in an effort to get IT faster to the cloud.  It may look incredibly attractive to sales, but the truth of it is, it can be like setting up land mines in your own yard.

East Coast Oracle Conference, (ECO 17)

So this week I’m back on the other coast, Raleigh, NC at ECO17 after last week in Seattle. I’ve switched from SQL Server to Oracle and we won’t discuss how many times I had to correct myself as I said, “transaction log” instead of “archive log” and pointed west instead of east for the ocean…My expression at times was similar to Obi Wan’s-

For the next month, I’ll be sticking to the Oracle side, as this is going to be a crazy month for travel.  My two sessions at ECO this week were well attended and I really enjoyed talking to folks and learning some new schtuff.

VirtualBox 5.2 exports the VM to the Oracle Cloud

The new release of Oracle VM VirtualBox (aka VirtualBox) is there with a new functionality to export a VM to the Oracle Cloud Compute (aka Oracle Cloud Infrastructure). That can be interesting to prepare a VM on my laptop and move it to the Cloud to get it accessible from everywhere. Here’s my first try. In my opinion, it’s idea but probably need further evolution.

VirtualBox

Here is what is new: in addition to .ova you can export to an Oracle Public Cloud image:

What I Learned At Oracle Open World 2017

My Oracle Open World started with a beautiful Sunday-morning run across San Francisco’s Golden Gate Bridge annual event organized by Oracle’s SQL Developer team (thanks Jeff)! Monday morning another group met for our annual San Francisco Bay Swim at the Dolphin Swim club; thanks to the Oracle Developer Community for providing coffee, pastries, and cool towels (thanks Jennifer)!

Oracle’s Open World was a little cozier this year; most sessions were at Moscone and hotels in close proximity making it easier to get from event to event. More time in sessions and less time in transit; good swap.

Am I a DBA 3.0 or just an SQL*DBA?

There are currently a lot of new buzz words and re-namings which suggest that our DBA role is changing, most of them escorted with a #cloud hashtag. Oracle Technology Network is now called Oracle Developer Community. Larry Ellison announced the database that does not need to be operated by humans. And people talking about the death of DBA, about the future of DBA, about DBA 3.0,…

Data Gravity and the Network

The network has often been viewed as “no man’s land” for the DBA-  Our tools may identify network latency, but rarely does it go into any details, designating the network outside our jurisdiction.

As we work through data gravity, i.e. the weight of data, the pull of applications, services, etc. to data sources, we have to inspect what connects it to the data and slows it down.  Yes, the network.

Archaic Data Transfer- A DBA Rant

There was a great post by Noel Yuhanna on how he deems the number of DBAs required in a database environment by size and number of databases.  This challenge has created a situation where data platforms are searching for ways to remove this roadblock and eliminate the skills needed to manage the database tier.
