January 15, 2016 Since October 2015 I have been fighting with an application programming interface (API) that works with an enterprise resource planning (ERP) system.  The API, with uses Microsoft .Net 4.0 or higher, is intended to simplify the process of automating the creation of various types of documents within the ERP system.  For example, the API […]

Friday Philosophy Guest: Open Source Projects

This post is Guest Post by my friend Liron Amitzi, an Oracle Ace, presenter and instructor who specialises in Oracle design & infrastructure. You can find his blog over here.  And with that, over to you Liron :-)

 

I have been wondering about open source projects for a while. I’ve talked to quite a few people about it, and still don’t really understand some of it. So I decided to write a post about my thoughts regarding this issue.

I’m not going to talk (or even mention) specific projects, but it is very interesting to me how these projects run.

Color Choosing in Squarespace

Choosing colors for a new Squarespace site challenges me. There are 16+ million colors to choose from, times the number of elements in the Style Editor that I'm able to colorize. That's some scary math right there, and it helps a lot to reduce my options.

Drawing from Preexisting Artwork

Figures 1 and 2 show recent sites that I've stood up on Squarespace, and I'm pretty happy with their color schemes. Figure 1 is the "easy" case, a redesign for a cycling club's website. There was a logo in play that had been designed by a professional graphic artist. She'd done a good job in choosing colors, and all the club members were more than happy her work.

Color Choosing in Squarespace

Choosing colors for a new Squarespace site ironically is made much easier
if you find good ways to limit your options. Otherwise the 16+ million
colors from the color wheels become overwhelming....

New Features of Enterprise Manager Cloud Control 13c

For those of you that have been wondering why I’ve been so quiet of recent times, it’s because my wife and I took advantage of a trip to England for UKOUG in December to spend nearly 5 weeks touring around Europe (2 weeks of which was spent river cruising from Amsterdam to Budapest with the fabulous APT river cruises, something I can HIGHLY recommend if you want to see Europe!). But while I might have been taking time off, you can bet the Enterprise Manager developers were not, with the result that Enterprise Manager Cloud Control 13c was released just before Christmas! That makes two releases in a row where Enterprise Manager is the first Oracle product to use a new major version number – EM 12.1.0.1 was the first product to use the version number 12, while EM 13.1.0.0 was the first product to use the version number 13!

YouTube : 6 Months and 1000 Subscribers!

That’s right, it’s been a touch over 6 months and my YouTube channel has just hit the 1000 subscriber mark. :)

This YouTube experience has been quite odd. My plan was to try and upload a video every weekday for the first 2 months, and I came pretty close to hitting that target. Once I had got a bit of content on the channel, I was inevitably going to kick back a little. After all, there is the website, the blog, life and that annoyance they call work to consider. I think a realistic target is to aim for is 1-2 videos a week.

Top Executions SQL Monitoring style reports in SQLd360

I think SQL Monitoring is an amazing tool when it comes to SQL Tuning but I often find that for one reason or another the report is almost never around for post-mortem investigation.
Historical SQL Monitoring reports have been introduced in 12c but still the decision to collect or no the report for the SQL ID we are interested in depends on several factors we have no control on after the issue happened </p />

Indexes and Initrans (Blackstar)

It’s been a very tough week so to help keep my mind off rather sad events, thought I’ll finish off one of my unpublished articles. Initrans is a physical attribute that determines the initial number of concurrent transaction entries allocated within each data block for a given table/index/cluster. Every transaction that updates a block has to acquire an […]
