2014 Year in Review

As many bloggers and sites do this time of the year, here is my review of 2014. It was a great year and it was a lot of fun, as well as educational reviewing all the data.

Busiest Day on my Blog:

uhesse.com in 2014 – a Review

Better than ever

2014 brought a new high water mark with 282,000 hits!

Meanwhile, uhesse.com gets over 1,000 hits per day on average.

Who are the referrers?

The vast majority of visitors came to uhesse.com via google searches: 163,000

On a distant second place is Twitter: 2,500 visitors came from there

Facebook and LinkedIn each lead 800 visitors to uhesse.com

400 visitors came from jonathanlewis.wordpress.com – thank you, Jonathan!

Where did uhesse.com refer to?

As a good employee, I sent 1,500 visitors to education.oracle.com and 1,300 to oracle.com :-)

STEM to STEAM, Andy Savage, and a manipulative huffpost ad that could have been great

Andy Savage gave a powerful and on-target keynote at the Collaborate Conference (Quest, OAUG, and IOUG #C14LV). There is a nice summary at http://collaborate.ioug.org/p/bl/et/blogid=40&blogaid=289 , which I recommend. My favorite bit was point #7 : Art belongs in the same discussions as Science, Technology, Engineering and Mathematics (S.T.E.A.M., not S.T.E.M.).

Andy phrased his entire take, even the bits of irony, on calling for positive action.

This is in contrast to a recent huffpost manipulation: http://www.huffingtonpost.com/2014/06/24/verizon-ad-tells-parents-to-encourage-girls_n_5526236.html

The Right Tools for the Job

I chose to work for Oracle because I wanted to immerse myself in the Oracle Enterprise Manager product.  It was the right place for me.  It didn’t matter that I had a background as a multi-platform DBA or that I my skill set was deeply involved in optimization of complex, large databases.  I knew it was right for me and I trust my instincts.  Due to research and the opportunities preesented to me, I have a great career, great p

Just in case

For those who don’t read Oracle-l and haven’t found Nikolay Savvinov’s blog, here’s a little note pulling together a recent question on Oracle-L and a relevant (and probably unexpected) observation from the blog. The question (paraphrased) was:

The developers/data modelers are creating all the tables with varchar2(4000) as standard by default “Just in case we need it”. What do you think of this idea?

Data Guard and Oracle Restart, aka relink always !!!

During my early years with PC I love to play "Leisure Suit Larry" (especially part 1 to 3 which has running on CGA or Hercules graphics card). Author of this games, Al Lowe had a good sense of humor and every time you failed your mission or stuck in a place - there was an pop up on the screen "Al says: save early, save often". After today fight with Oracle I should remember a next saying - "Relink after, relink always".

Let me explain what what happen today.

Learning

I received an email a few weeks ago asking me if I would look at a series of three posts on adaptive dynamic sampling in 12c – (part 1, part 2, part 3). I took a note of the topic and URLs, and read through them fairly rapidly, and they seemed to be perfectly reasonable articles describing the authors thoughts, tests, and observations.
