photo by Chase Elliott Clark Here a video on using Jetstream which I like to call “DevOps Jetpack for Developers” (Remember you can get Delphix Express and Jet Stream for free.) See previous blog post on how to set up Jet Stream. With Jet Stream, users can control their data. Users can refresh their data from the source, users can bookmark data to rollback to, users can bookmark their data and share those bookmarks with other users so that those uses can access the same data. In the video Part I QA person adds edge case data to a copy of production data…

So I’ll be heading out for Oracle Open World 2015 in just over another week. This is the first year in a while that I won’t be speaking, (my own fault, as dummy here hasn’t figured out how to submit sessions internally yet, duh!) but I’m still going to support the demo grounds, meet with customers and speak at Oak Table World! Per Steve Karam, if you need to know who’s speaking and why you should attend the sessions at the Children’s Museum, well here’s a few: Jonathan Lewis – Yes. That Jonathan Lewis. Also an alien of extraordinary…

Delphix has a developer self service interface called “Jetstream.” I like to call it the “DevOps Jetpack” for developers. Jetstream is available both in the Delphix enterprise engine and also in the free Delphix Express engine. See following blog post on users using Jet Stream. Here is a video on how to setup Jetstream for two users, a developer (Joe Dev) and a QA analyst (Jane QA). In a blog post to follow this one, we will see how Joe Dev and Jane QA can work together thanks to Jetstream which allows them to share versions of data (similar to how people can…

I’ve been a bit busy traveling and speaking, but I wanted to discuss the great events I’ve been lucky enough to be part of the last couple weeks. Indianapolis Oracle User Group I spoke at the INOUG back on September 17th. The user group in Indiana is incredibly welcoming and I had a great time with the wonderful attendees for my three back-to-back sessions. We discussed AWR Warehouse, ASH and AWR Mining and a new session on Optimization for EM12c and the Hybrid Cloud. East Coast Oracle Conference September 21st-23rd was my first visit to the great city of Raleigh,…

I have previously announced that Delphix now has a free version available called Delphix Express as well as how to install Delphix Express. In this blog will look at an example of virtualizing your first database and not only the database but virtualizing the application as well. What does virtualizing mean? Like in the world of virtual machines where we make multiple virtual machines on one set of hardware, in the world of virtual data we make many read/write copies of data with one actual physical copy of the data. We do that by sharing unmodified data and storing each…

So as I prepare for next week, coaching with some other great folks with the Oracle Education Foundation using the Raspberry Pi, I wanted to add some fun music into my code to work with our motor mascot project. To do so, you need a few things: A small speaker with a 3.5 plugin to the Raspberry Pi. I have a small, round, rechargeable one that I love. Have an FM radio station that streams music that you can use in your code. Install and use music libraries If you haven’t done so recently, run an update on your Rpi: sudo…

This post is part of a series Delphix Express: Installation Delphix Express: Virtualizing a database and web application Delphix Express: Setting up Jetstream Delphix Express: Using Jetstream A couple of blog post ago I announced that there is now a free version of Delphix. Here is a little more information about the installation of Delphix Express. To get Delphix Express, the free version of Delphix, go to http://download.delphix.com and create an account, then log in. You should see a DelphixExpress folder. Click on it and you can download the OVAs. Delphix Express Delphix Express clones databases in minutes for almost not storage and…

Delphix Express is available! To get a copy of Delphix Express go to http://pages.delphix.com/Free-Trial-Request.html and put “Express” for your title and I’ll send you the download info. Delphix Express is a free version of Delphix Delphix Express differs from Delphix enterprise in that it is limited to 25 GB of managed storage. Installation Example Virtualizing Example Here is a video on installing Delphix Express on VMware fusion on my Mac. Delphix Express can also be installed on Virtualbox. Here is a quick video showing how to create a virtual database as well as a virtual database application using Delphix…

So I’m going to start this post with an admission- I don’t have access to a cloud environment to test this out, but I know what I would do first if I experienced slow response time on database creation or cloning via EM12c to the cloud and I would like to at LEAST post what I would do to give others the chance to test it out and see if it offers them some help. Knowing what is causing slow performance is essential to trouble shooting any problem. I’ve had a few folks come to me with complaints that their hybrid…

As the Training Days Director for Rocky Mountain Oracle User Group, one of my tasks is not just running the conference for RMOUG, but also promoting it. RMOUG Training Days was the first conference I ever attended, (2004) and the first one I ever presented at, (2009.) Its one of the reasons my career is where it is now and how I stayed in touch with the man who is now my partner in life, best friend and husband. The Training Days conference is the largest regional Oracle User Group conference in the US and is held each year…

So one of the things I like to do is test out a lot of my python gaming code, (as far as for the coding and syntax) on my Oracle Virtualbox image of my Raspberry Pi. Another great thing about building games on the Raspberry Pi, is a built in module called Pygame. Well, that doesn’t exist on the Raspberry Pi image and it really limits what we can do when it comes to the VNC build we play on the Oracle Virtualbox, (that’s a mouthful… :)) Get Outside Access The first step is to first get out to all…

Everything I do with the Raspberry Pi is about finding ways to incorporate STEAM, (Science, Technology, Engineering, Art and Math) into my projects. This is no easy feat, but I have a lot of fun while I try. This latest project, we’re still working on ways to “enhance” and understand how code can be used with multiple projects and to satisfy multiple requirements. Science Kit Projects, to the Nth Level Our first project used DC motors to make an art project or spinner turn at the appropriate rotation required. I then was able to repurpose this same code to bypass…

Creating a trace file from EM12c is quite easy and doesn’t require a DBA offering up the world to allow a developer or support person to perform this action. Enterprise Manager also removes some of the syntax options that could get a developer or app support person that is less specialized in creating trace files, all the options and the knowledge of the syntax, etc. from getting into trouble, which creates an option for everyone to be successful. The proposed solution that I’ll post here is where the EM12c user will be able to create trace files, but the DBA will control the…

Back on August 7th, the RMOUG’s Quarterly Education Workshop, I walked everyone through using a Pibrella board to create an art or flyer project that was powered with a python script and a motor. Today, we’re going to take that same code and reuse it with a simple robotics kit to control power and rotation speeds/time to the Insectoid. This kit, puchased from the Go! store in Flat Irons Crossing mall, was $16 and can be built in less than an hour, even for a small child. If you’re interested, you can also purchase the kit online at Amazon, but…

So I don’t doubt that many parents are bleeding out money for kid’s school fees, supplies, clothing and other demands this time of year. How many of you are in their local Target, Walmart or other store and after filling the cart with the necessary, the kids eye up the toy aisle and start to ask for something? Even teens are not immune and may be asking for games. If you could turn around and say to them, “If you want the game, then why don’t you build it instead of buying it?” Now as many of you have figured…

There’s an old joke about the evolution of a programmer. It starts with the programmer in their infancy and typing: Print “Hello World” and so the output returns: The programmer continues to evolve. His coding knowledge increases and his code in the end of his evolution becomes a script of 5000 to 10,000 lines. What does the output return? You guessed it: I often joked that I’d make a terrible developer. I over think everything, but the truth is, I may have just evolved too much and need to devolve to improve. There used to be a sign up on…

So I’m working on a lot of posts for Enterprise Manager, but I can’t post them just yet, so here’s some more Raspberry Pi love to keep you busy until then… 🙂 Why VBox Raspberry Pi? Many times I just want to write and test some code, but I want to do it while I’m taking a break from my day to day work- waiting for a download, in a meeting, a script is running in another window, etc., so it’s convenient to have a Virtualbox image to run Python scripts with all the libraries and modules installed. I can’t…

RMOUG’s Quarterly education workshop was a great event today and I appreciate everyone who came out and those who spent time with their family and their user community doing fun geeky stuff. Raspberry Pi Family Coding Morning There were a few things I promised folks, including access to my family coding slides so anyone can do this at home. Even though I’ve included the GPIO with breadboard configuration and code in the slides, please, PLEASE consider getting the Pibrella board and code with it instead. The chance of wiring the board wrong is high for those just starting out and…
