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.
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.
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 (more...)
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 (more...)
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, (more...)
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 (more...)
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.
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 (more...)
I’ve had a lot of people email and message me asking me what I’m doing with the Raspberry Pi and I wanted to share before the actual RMOUG Quarterly Education Workshop, (QEW) this Friday at Elitches.
So a little history- When I was a kid, I was a real handful. My mother used to come into my room and I’d have created “webs” out of yarn strung from every piece of furniture and twisted into (more...)
Back in 2002, as a Junior DBA, I was informed by the senior DBAs I worked with that I MUST become part of my regional user group, (RMOUG). This was considered a requirement for any educated Database Administrator or Developer of the time and as those who I respected instructed, I became a member and attended my first Rocky Mountain Oracle User Group Training Days in February, 2003. I was impressed (more...)
More and more companies are consolidating environments. Server sprawl has a high cost to any business and finding ways to consolidate to more powerful servers or to the cloud is a productive undertaking for any company.
The Consolidation planner in Enterprise Manager has been around for quite some time, but many still don’t utilize this great feature.
Creating a Consolidation Project
You can access the Consolidation Planner from the main Enterprise menu from Cloud Control (more...)
Unlike other forms of communication, social media can be a real gray area for rules on what dictates freedom of speech and how you have to endure with those that may not be pleasant to interact with. I’m often told what etiquette some feel it necessary and that I should just disengage from some people online.
The truth is, not everyone gets social media and many just don’t understand boundaries or how to communicate productively (more...)
Happy Birthday to me! So for my birthday, I give a present to you… As I want all DBAs to sleep better at night, here are the top ten features you can use in Enterprise Manager Cloud Control to offer a good night’s rest instead of during the day at your desk…
1. Disable the Default Rule Sets Shipped with Cloud Control.
Yes, you heard me. I believe you should use them as a (more...)
I had a chance to take a closer look at the Zero Data Loss Recovery Appliance, (ZDLRA) via Cloud Control today and really liked the dashboard that’s included in the plugin for the product. This post isn’t going to cover the installation of the plugin or configuration- I was just intrigued by the dashboard and wanted to go over the great features that are part of it.
Accessing the ZDLRA
As with any Targets, (more...)
The sales, support and technical teams were brought into the Denver Tech Center office to do some advanced training in Hybrid Cloud. There were many take-aways from the days we spent in the office, (which is saying a lot- most of you likely know how much I hate working anywhere but from home… :)) and I thought I would share a bit of this information with those that are aching for more details on (more...)
I’m glad to be home after a couple weeks in Europe, speaking at both the Harmony 15 conference in beautiful Tallinn, Estonia and then as a keynote speaker at AOUG in lovely Vienna, Austria the week after. I get to pretty much stay close to home for the next two months, traveling only a bit, but I want to go over the upcoming conferences that I’ll be speaking at the next couple months.
July 23rd, (more...)
Last week’s release of 184.108.40.206 was a pleasant surprise for everyone out in the Oracle world. This release hit the bulls-eye for another cloud target of Oracle’s, announcing the introduction of Enterprise Manager 12c’s offering a single pane of glass management of the hybrid cloud. The EM12c team has been been trained and testing out the new features of this release with great enthusiasm and I have to admit, pretty cool stuff, folks!
When you need to have information about one SQL_ID and don’t need everything and the kitchen sink, there are a few different ways to collect this via Oracle. I’m surprised how rarely this is covered in performance tuning/optimization, (whatever the current “acceptable” term is for fixing a database when there are performance issues arise… J) classes, manuals and documentation. I’d like to cover two of my favorite here and know, there are other options (more...)
I recently upgraded from the first edition Raspberry Pi to the new and improved Raspberry Pi 2 in a bundle Cana kit. The Raspberry Pi 2 has a 900MHZ quad-core Arm Cortex A7, (ARMv7 processor instruction set) with 1Gb of memory, GPU is a 250MHZ Broadcom VideoCore IV, 1080p 30 h.264/MPEG-4 AVC high profile decoder and encoder on the graphics and includes four USB ports, a micro SD, HDMI, micro USB power supply (more...)
