Nostalgia and choosing your in-flight movie

First thing to note on this post. No tech content in this one. Just some nostalgia.

Couple of days ago, I was flying from Perth to Dubai on my way to APEX Connect in Bonn. Because this is an 11hour hell in a death tube flight I settled in to my standard sleepless task of watching movies to pass the time. I try to steer clear of going exclusively with new releases because I know I’ll always be travelling again soon, so I try not to exhaust all my options too soon Smile

I was browsing through the “Movie Classics” section and found a movie from my childhood: The Right Stuff.

Oracle Magazine

Generally my blog is just snippets of tech content that take my interest as I encounter them (most commonly when looking at AskTOM). If I think they’ll be useful, I’ll just plonk them out right there and then. If you prefer your content in longer (and more structured Smile) form, then also I publish longer form articles on Oracle Magazine every couple of months. Below is a consolidated list of my articles. I’ll try to keep this list updated as I add new ones.

Old Dog, New Tricks, Part 2
Here’s a new SQL syntax for hierarchy processing.

Work Life Travel balance

I thought about writing a post on juggling work commitments, travel with my job and time at home with children and family. And then I came across this post from community friend Robin Moffatt.

You need scaling huh? Maybe it’s just ego

I’ve just come back from OracleCode Singapore.  It was a great event – the venue was awesome and the attendees were engaged and interested in the content. But there was one thing that I found amusing (disturbing perhaps?) is the number of times I had people approach me on the topic of scaling.  Conversation would typically run along the lines of:

“What is your recommendation for scaling?”

which almost suggests that scaling is of itself, the end solution here.  Not “Here is function X, and I need it to scale”, or “My business requirement is X, and it needs to scale” but just “I need to scale”

When you screw up … make it positive for your users

Yesterday I was caught up in an interesting SNAFU at my local Supermarket.  All of the checkout registers shut down, thus making it impossible to pay for groceries.  Later on Twitter, the company apologized as we discovered it was actually a nationwide outage!

 

TO_DOG_YEAR

Some members of the Oracle community got well and truly into the April Fools Day spirit this year.

There were plenty of very earnest looking blog posts about a new 18c function – “TO_DOG_YEAR”.  You can read their posts here

AskTOM Office Hours for DBA’s

We had the first AskTOM Office Hours Q&A for Database Administrators yesterday.  Thanks to everyone that showed up, and thanks for the questions.

It’s not about ego … it’s about knowledge

Take a quick look at this blog post by Jonathan Lewis

https://jonathanlewis.wordpress.com/2017/12/30/nvarchar2/

Anyone that has been working with Oracle for any length of time probably knows that Jonathan has a great depth of knowledge in the Oracle database, and is a regular blogger.  But this post is a good example to inspire anyone that is working with Oracle (or any technology for that matter) to start blogging and sharing their experiences with the community, no matter what their level of experience is.

If you read the post, you’ll see that Jonathan presented a well-crafted test case, and presented a hypothesis about NVARCHAR2 and potential side effects of adding columns of this data type to an existing table.

2017–what grabbed your attention

Here are the blog posts that you hit on most this year.  Thanks for supporting the blog, and always, there will be more content next year !

Buffer cache hit ratio–blast from the past

I was perusing some old content during a hard drive “spring clean” the other day, and I found an old gem from way back in 2001.  A time when the database community were trying to dispel the myth that all database performance issues could be tracked back to,  and solved via, the database buffer cache hit ratio.  Thankfully, much of that folklore has now passed into the realm of fiction, but I remember at the time, as a means of showing how silly some of the claims were, I published a routine that would generate any buffer cache hit ratio you desired.  It just simply ran a query to burn through logical I/O’s (and burn a whole in your CPU!) until the required number of operations bumped up the buffer cache hit ratio to whatever number you liked Smile
