Provisioning Virtual ASM (vASM)

Create vFiles

In this post, we’re going to use Delphix to create a virtual ASM diskgroup, and provision a clone of the virtual ASM diskgroup to a target system. I call it vASM, which is pronounced “vawesome.” Let’s make it happen.

Real Push Button Refresh with Raspberry Pi

Push Button

In this post, we’re going to perform a push button refresh of an Oracle Database, Application Express (APEX) installation, and Tomcat webserver.

“But Oracle Alchemist,” you’re probably thinking, “we know about that. You’ve told us about how Delphix can provision and refresh data.” And yes, you’d be right. But I wasn’t done yet.

We’re going to perform a refresh of an Oracle Database, APEX installation, and Tomcat running in Amazon Web Services, replicated from (more...)

Oracle APEX 5.0 Available for Download!

After a longer development cycle than usual, Oracle Application Express 5.0 is finally available for download! I think it was worth the wait. It comes with a ton of features, here are just a few marquee features. Page Designer Universal … Continue reading

Deploying Application Express with Delphix

VDBs

Seamless cloning of an application stack is an outstanding goal. Seamless cloning of an application stack including the full production database, application server, and webserver in a few minutes with next to zero disk space used or configuration required is the best goal since Alexander Graham Bell decided he wanted a better way tell Mr. Watson to “come here.”

So in the spirit of discovery, I’ve installed Oracle REST Data Services (ORDS) 2.0 (more...)

It's been a very long time not coming here, about 2 years and half ... and I missed it big time.

Now I moved to Oracle Systems (formerly Sun Microsystems) on a role support-programmer mixed, within RPE (Revenue Product Engineering) on the Extra Care team, with focus on Solaris, Engineered Systems with Solaris, ZFS Storage Appliance and Ops Center. I'm very happy since my job is closer to development, something was (more...)

Managing your Database in a Zombie Apocalypse

Zombie Server Room

Only two things are really certain: network latency over long distances, and the fact that humanity will soon rapidly degenerate into undead brain-eaters.

When that day comes, when the dead are crowding at your door and the windows are busted out and ripped up rotted arms are clawing at the inside of your home, I know what you’ll be thinking: is my database protected?

Don’t worry, my friends. The Oracle Alchemist has you covered. We (more...)

Another Great OpenWorld

Steve at the Delphix Booth

Last week I attended Oracle OpenWorld 2014, and it was an outstanding event filled with great people, awesome sessions, and a few outstanding notable experiences.

Personally I thought the messaging behind the conference itself wasn’t as amazing and upbeat as OpenWorld 2013, but that’s almost to be expected. Last year there was a ton of buzz around the introduction of Oracle 12c, Big Data was a buzzword that people were totally excited (more...)

Openworld 2014

Oracle OpenWorld

Are you going to Oracle OpenWorld 2014? I am, and I hope to see you there! As you probably know, OpenWorld is a humongous event with tens of thousands of people in attendance and some amazing presentations. Why, I even hear Oracle’s new CTO might be there. I wonder if he has anything to talk about?

This year we’ll have a ton of activity at the Delphix booth. You can check out the speaking schedule, (more...)

Teach Your Children Well

computerroom

Today’s the first day of school in my city, and the plethora of “OMG 1st day of school!” posts of Facebook and my own kids heading back in to slog through another year of fundamentals got me thinking about education. My own kids (12/daughter and 10/son) came home and went swimming since it was about 104 degrees today…the hottest day of the summer, as it were.

The Customer Experience

The Apple Experience

I’m going to kick this post off by taking sides in a long-standing feud.

Apple is amazing.

There. Edgy, right? Okay, so maybe you don’t agree with me, but you have to admit that a whole lot of people do. Why is that?

Frequently Misused Metrics in Oracle

Lying Businessman

Back in March of last year I wrote an article on the five frequently misused metrics in Oracle: These Aren’t the Metrics You’re Looking For.

To sum up, my five picks for the most misused metrics were:

Business Graph

  1. db file scattered read – Scattered reads aren’t always full table scans, and they’re certainly not always bad.
  2. Parse to Execute Ratio – This is not a metric that shows how often you’re hard parsing, no matter how (more...)

IT Stockholm Syndrome

Shrugging

Random thoughts on a Friday afternoon…

We’ve all got problems. More to the point, every IT department or team has problems of some kind. It’s why we hire consultants, buy products, start long and arduous journeys into the great unknown depths of root cause analysis, and so on.

What fascinates me is the level at which we come to identify with our problems. When I’ve gone into an environment to deliver recommendations, the conversation usually (more...)

Why use OVM for Oracle Databases

Some time ago I made a benchmark exercise to compare the performance of an Oracle Database running in a bare metal environment versus a virtualized environment to clear some of the main questions our team and clients in Revera have,
