ADWC: start/stop with PSM Command Line Interface

By Franck Pachot

.
In the previous post, I explained how to create an Autonomous Data Warehouse with PSM (PaaS Service Manager Command Line Interface). The most common operation you want to do with it is starting and stopping the service. This is the best way to save credits for hourly billed services. And PSM is the easiest: run from everywhere (it is Python 3) and no need to provide credentials each time. In the previous post, I explained how to setup PSM for the ADWC service.

Unfortunately, for starting and stopping the instance you may realize that:

GDPR Solutions in the Day of Automation

There’s something for having job security and many of the solutions that I see offered for RDBMS challenges offer just that. With compliance with EU’s GDPR, (General Data Protection Regulations) just around the corner, (mark you calendar, May 25, 2018) you’d think we’d all be scrambling for a simpler solution to discovering and addressing all that GDPR data.

Quick refresher for those of you going, “What is GDPR?”

Data security is a known focus of GDPR when you talk to folks, but it’s much more than just security.  It’s about extended rights of the individual in the EU. There’s four areas as a DBA, you need to really concern yourself with:

A free persistent Google Cloud service with Oracle XE

In a previous post I’ve listed several free online services which run an Oracle XE so that you can test your SQL easily. You may want use Oracle XE further, with full access to the database and its host, and still from a web browser. You probably have a Google account. Then you also have a Virtual Machine on the Google Cloud (0.5 vCPU / 1.70 GB RAM boostable to 1 vCPU / 3.75 GB) and 5 GB of persistent storage (as long as you used it in the 120 previous days). Just try this Google Cloud Shell: https://console.cloud.google.com/cloudshell.
In this post, I explain how to install Oracle XE there.

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:
