Open Source? We have been here before… right!


Since over half a year I have made an adjustment in my course… nothing too dramatic, but still it has had some impact.

I have chosen the path of the more pure technique again. Not in a sense that I don’t manage anymore, though I don’t, but that’s more of a side effect
I have chosen the path of the more pure technique in a sense that the change from Closed Source software to Open Source software allows you to actually work with and solve things by creating solutions rather than trying to figure out how something, someone created for some issue, can reconfigured so it resembles a solution for your actual problem.

Okay… okay… this of course is exaggerated, but it serves to help think about the issue.

No one ever got fired for buying Oracle” is one of the phrases I have heard numerous times over the past period.
Well, no… but it’s also no free pass to –sorry for the phrase– waste money on technology you either never going to use.

Over 80% of the installed base uses less than
20% of the technology they are paying for!

I have followed a number of the brightest mind in the industry (our industry, the database industry) for many years investing vast amounts of time in reverse-engineering pieces of technology that have been built, in order to explain certain behavior.
Of course, very necessary, no argument there, but wouldn’t it be so much more cool if this overwhelming amount of brain-power could be used to actually create stuff??

Open Source in stead of Closed Source…
The answer, I think!

Sure, I am raised with vendor created solutions, that was the default MO when I got trained. VMS, MS-DOS, HP-UX… (are you _that_ old, yes, I am _that_ old) and a number of applications that did the work.
Well, those days are gone… operating systems in data centers have (nearly) all been replaced by Linux distribution installs. And I mean like, as good as all of them.

Sufficiently stable, cost effective and they get the job done.

Next wave?
Databases!

With the current explosive growth of Open Source databases, brace yourselves. Or rather, embrace!

All the exact same arguments that are there for Operating Systems apply. There is no difference, and you, the industry, chose! And you will choose this again. Simply because “it is good enough”, it is much more cost effective and it gets the job done.
The extensibility, the agility of Open Source database software gives you the ability to let your database, be it OLTP, OLAP, Big Data, Polyglot, or whatever we come up with, do what needs to be done.
The current leader of the Open Source relational database systems is PostgreSQL. A platform developed in over 30 years to become an absolutely stable data processing engine for a fraction of the costs of the Closed Source players in this market.

Conclusion:

  1. We have seen wave 1 of Open Source where we all choose to replace the operating system standard with Linux.
  2. We will now see wave 2 of Open Source where we will choose to replace the database management system standard with… PostgreSQL (or in specific cases one of the other, more specialized systems, depending on the need).
Hope this helps!


The importance of meetup.com

The Oracle community convenes at the various events, SIG-meetings and gatherings that are organized by the national Oracle User Group organizations. This is, for my reckoning, one if the most important parts of the power of the Oracle user community.

During these events, local Oracle stars are joined by the travelling Rock Stars of the Oracle Tech community, together they share knowledge and experience to teach and learn about the tricks of the trace. As said many times before, by people much greater than me, this is truly a unique and powerful way to nurture and grow the combined knowledge about Oracle products and the best ways to use them. My favorite quote remains that of Monty Laitiolais: “This truly is a celebration of Tech!” where he obviously was referring to the yearly KScope happening, but which easily translates to many of the Oracle events around the globe.

Since quite a while now, the phenomenon meetup.com has emerged. It is an on-line place where people can initiate meet ups of like-minded people. Either being a small initiative with just a few people in a cafe up to bigger, or perhaps more commercially colored, happenings. Whatever the subject or idea, from travel to innovation and from hobby to profession, you can find a meet up to suit your needs.

Even though the richness and the broadness of the activities of the Oracle User Group organizations worldwide, recently I have seen more and more activities of Oracle aficionados on Meetup.com.
As far as I recall, the ever-vibrant APEX community started organizing these kinds of events under the flag of APEX-meet ups, using this platform. Gathering to share best practices and share experiences about APEX and all the various bit and pieces that adhere to this technology.
If you would look at the following list you would conclude that it even has quite a big list of meetups there… The adoption of meetup.com by the Oracle community is growing rapidly.

Is this a bad thing for the ‘regular’ Oracle user community?

I think not.

From my experiences participating in both “regular” Oracle user group events as well as in Oracle-related meet ups, I think they have a complimentary function.
The traditional user group events are usually more “speaker – audience” oriented, which is a very good format for educating and teaching. A format that is indispensable because it enables a larger group of people to gain knowledge and understanding quickly and effectively.
The meetups have a, let’s call it, more informal character, one where the interchange of information and knowledge is more of a group event. And, let’s face it, the social aspect of meetups is also a little more on the foreground, which in itself is a good thing too.
The need for this kind of contact already was there in the form of SIG’s. During the traditional events, with the emerging of the round-table phenomenon, this has been even more obvious.

Conclusive I would like to state: Let’s embrace meet ups. Go find or organize a meet up – preferably about our much-loved Oracle technology – in your neighborhood. Find and inspire people, share, learn and laugh! It is worth your time, I can tell from experience.

Big Data: Hadoop and Oracle technologies explained

MarkRittmanUnder the title “Hadoop and Oracle technologies on BI projects” Mark Rittman flew to The Netherlands on the 14th of July to visit the Oracle Usergroup Holland.

As I had obviously heard a lot about Hadoop, I never really did anything further with it and left it to a synaptic link to Gwen Shapira. This lack of action created a kind of threshold in the understanding of the technology. When I heard about this session I realized this would be the moment to take a step further. It turned out the be the  first real talk that puts “Big Data” in the perspective it needs to be consumable and realistic.

In these current times where “The Internet of Things”, more and more social media and ever further digitization we are heading to a Big Data Disruption. This is both a conceptual as a very real thing if you take a moment to think about it. According to real world experience it is also not something “which will once be”, it is something which is actually here today!

On the technical side of thhadoopings, data is captured in something that is called a “data reservoir” (or “data lake” or “data dump (yard)”). Compared with “regular” data storage, you can conclude that data-governance, or a data-structure, in a Big Data system is applied later  We are used to apply this structure, this governance, beforehand, by applying data definition. Using Hadoop in combination with noSQL give you “schema on read” capabilities making quering of the Hadoop data reservoir possible.

Adding this structure later is harder! This leads to the following:

  • Data is much easier to get into Hadoop then into a star-schema
  • Data is much easier to get out of a star-schema then out of Hadoop

This could be one of the essential things to consider when thinking about engaging in a Big Data project!

As Tanel Poder concluded: “High value, high density data will remain in the Oracle database” which I think is a very true conclusion. In the end, the high value conclusions (or the engineering of Big Data results) will also happen within the Oracle database.

On the horizon is “Oracle Big Data Discovery” which will help with the time consuming and tedious work of sorting and interpreting raw data in the data reservoir. The use of ‘R’, as the data exploration tool of duty, is expected to be replaced by this discovery tooling, over time…

To sum up the concept of the first half of the presentation, to my taste:

  • Hadoop changes business
  • NoSQL scales business
  • Oracle runs business

It takes eons to list all names of the Buddha” nicely sums up the number of different applications that make up and are needed to execute a successful Big Data project.
Plus, “You’d better keep the 13 rules for relational databases close at hand“!

presentation

Part two of the evening was spent on mapping these concepts on actually tools, disclosing data through Hadoop to Oracle SQL and making actual use of Big Data. The exercise was completed by demos and illustrated by screenshots from the slides (link below).
A special word of warning goes out to the security aspect of Big Data, which is something to really pay close attention to. Kerberos authentication and apache Sentry are imperative things to implement in your Big Data environment.

All in all, this evening turned out to be 110% more informative and necessary as I expected when I embarked on the journey to Utrecht! Thank you for sharing, Mark!

Thanks to Piet de Visser for the nice quotes! And a great “hi there” to Klaas-jan Jongsma, René Kuipers and Marti Koppelmans.

Share your passion

What I have encountered over the past few years, as I got  more and more involved in the Oracle User Community, is the passion to share.
As I have stated in previous posts, it is unbelievable how many smart people are willing to invest private time AND money to travel the world and to share knowledge and experience they have accumulated over the years.

Typically, the annual Oracle User Group events are the place to be to learn from these people. And most often many will submit abstracts of their stories to be elected to be part of these events.

Only, to be able to submit these abstracts, you need to know:
– when these events are
and
– when the so-called CFP (Call for Papers)
is open.

As all Oracle User Groups tend to be independent, this information is hard to come by if you’re not part of the in-crowd, which if, of course, a pity!!
My goal is to collect this data and make it centrally (well, as central as this website is, then) available to whomever is searching for it.

I have made a start.

It’s a small start yet, so:

  • If there are errors, correct me!
  • If information is missing, tell me!

Hope this helps!!

#RepAttack, it’s all about learning

Everything we do in our daily life is about learning. Especially in IT we are used to continuously learning. Digging through documentation, figuring out how this or that piece of software should work. Downloading, installing, configuring, trying, tweaking, tuning…
Dbvisit Standby

For Dbvisit, it all started with Dbvisit Standby. Logical data replication, but, logical data replication is not so hard in the end. To get it running stable, to make it do exactly what you want it to do, is an oversee-able task. With it’s wizard driven installer and the clear task of having two exactly the same databases and a little bit of time, you’ll have this process of shipping archived log files, nailed. Getting it stable and reliable is built in, so not much worry there.

Logical data replication on the other hand, is a whole different ballgame!
For a long time logical data replication was just for bigger companies with intricate information needs. And it is a little more challenging than physical data replication. There are database, schema or table considerations, what and what not to replicate to where, making sure you get it stable and reliable in your environment. Checking and following up on changes and doing all kinds of work to make sure you get the best our of your setup.

Nevertheless, Logical data replication will help you in doing:

  • “Zero downtime database migrations”
  • “Report offloading”
  • “Schema consolidation”
  • “Real-time business intelligence” operations

And because these things are about you…

You deserve a “flying headstart”

with Dbvisit Replicate!

Dbvisit_Replicate_HR croppedTo be able to bring you this, we looked at the heroes from the Oracle Technology Network for inspiration. This special group of gurus called the RACAttack Ninja’s have been involved in educating and supporting any and all with a setup of Oracle’s Real Application Cluster technology on your laptop.

Inspired by this example, Dbvisit created #RepAttack! A techno-opportunity that will be traveling the world with it’s inaugural session nowhere less than at Oracle Open World 2014.

#RepAttack is a great opportunity to network with your peers who are just as curious as you are, and to access a fantastic team of warriors who will work with you one-on-one to ensure you are up and running quickly and leaping over any hurdles effortlessly. The session will include a deep dive into core concepts to make sure you return to your organization with an in-depth understanding of how both replication and virtualization really work. Take the time to attend and be that “go-to” person when questions around these concepts come up at work.
