RMOUG Training Days 2018

Submitted by dbakevlar on Tue, 2018-02-06 21:33

So Training Days is coming up in two weeks.  You haven’t registered to attend?  How you feeling about that?

Rocky Mountain Oracle User Group, (RMOUG) has the largest Oracle user group grassroots conference each February.  For the 2018 year, we decided to shake it up with:

Spectre and Meltdown, Oracle Database, AWS, SLOB

Submitted by Franck Pachot on Tue, 2018-01-09 21:23

Last year, I measured the CPU performance for an Oracle Database on several types of AWS instances. Just by curiosity, I’ve run the same test (SLOB cached reads) now that Amazon has applied all Spectre and Meltdown mitigation patches.

I must admit that I wanted to test this on the Oracle Cloud first. I’ve updated a IaaS instance to the latest kernel but the Oracle Unbreakable Enterprise Kernel does not include the Meltdown fix yet, and booting on the Red Hat Compatible Kernel quickly goes to a kernel panic not finding the root LVM.

Upgrading an Amazon EC2 Delphix Target, Part IV

Submitted by dbakevlar on Mon, 2017-08-07 13:44

It’s finally time to upgrade our Linux Target!  OK, so we’re not going to upgrade the way a DBA would normally upgrade a database server when we’re working with virtualization.

So far, we’ve completed:

  • 1.  Updating our instances so that we’ll have a GUI interface if we’ll need one.
  • 2.  Installed Oracle on the Linux Source and upgraded our Dsource database to 12c

 

Now we’re done with our Linux Source and onto our Linux Target.

Upgrading an Amazon EC2 Delphix Source, Part III

Submitted by dbakevlar on Mon, 2017-07-31 18:40

This is the Part III in a four part series on how to:

  1.  Enable VNC Viewer access on Amazon EC2 hosts.
  2.  Install DB12c and upgrade a Dsource for Delphix from 11g to 12c, (12.1)
  3.  Update the Delphix Configuration to point to the newly upgraded 12c database and the new Oracle 12c home.
  4.  Install DB12c and upgrade target VDBs for Delphix residing on AWS to 12.1 from the newly upgraded source.

In Part II, we finished upgrading the Dsource database, but now we need to get it configured on the Delphix side.

I’m finally getting back to upgrading the Linux Source for a POC I’m doing with some folks and picking up from where we left off in Part I…

Address Display Issue

Now that we have our VNC Viewer working on our Amazon host, the first thing we’ll try is to run the Oracle installer, (unzipped location –> database –> runInstaller) but it’s going to fail because we’re missing the xdpinfo file.  To verify this, you’ll need to open up a terminal from Application –> System Tools –> Terminal:

Delivering Migration Projects on Time

Submitted by dbakevlar on Fri, 2017-04-28 18:02

I did a couple great sessions yesterday for the awesome Dallas Oracle User Group, (DOUG.)  It was the first time I did my thought leadership piece on Making Sense of the Cloud and it was a great talk, with some incredible questions from the DOUG attendees!

The Chicken Before the Egg of Cloud Migrations

Submitted by dbakevlar on Tue, 2017-04-18 22:38

For over a year I’ve been researching cloud migration best practices.  Consistently there was one red flag that trips me that I’m viewing recommended migration paths.  No matter what you read, just about all of them include the following high level steps:

TCP WMEM Fault in Delphix AWS Target

Submitted by dbakevlar on Fri, 2017-02-10 22:29

So you thought you were finished configuring your AWS target, eh?  I already posted a previous time on how to address a fault with the RMEM, but now we’re onto the WMEM.  Wait, WM-what?

So you’ve deployed targets with Delphix on AWS and you receive the following error:

Let’s face it: education without interaction is about as effective as shouting origami instructions at a lumberjack who is cutting down trees. Sure, your informative lessons will come in handy when the product of their work finally becomes paper, but it will be long forgotten and ultimately worthless by then. The only way a student is going to learn is if they can put their hands on what you’re teaching, walk the journey with you, and attach a positive interactive experience to the lesson.
