Less Performance Impact with Unified Auditing in #Oracle 12c

There is a new auditing architecture in place with Oracle Database 12c, called Unified Auditing. Why would you want to use it? Because it has significantly less performance impact than the old approach. We buffer now audit records in the SGA and write them asynchronously to disk, that’s the trick.

Deploying Apex: showing an “Under Maintenance” web page

systemdown

I’ve added this script to our toolbelt for future upgrades. We have a friendly “System is under maintenance, sorry for any convenience” web page that we want to show to users while we run upgrades, and we want it to be shown even if we’re just doing some database schema changes.

PL/SQL: The Good Parts

Somewhat inspired by Douglas Crockford's Javascript: The Good Parts presentation (and book), I have created a presentation called PL/SQL: The Good Parts.

Joining Oracle

Last month I joined Oracle after nearly 20 years of working with their technology.  Some people congratulated me on my new role, others told me that going from working solo to working for a massive organisation would be disaster.  In the latter case, this was often associated with an impassioned “But why?”

Why Move to Cassandra?

Nowadays Cassandra is getting a lot of attention, and we’re seeing more and more examples of companies moving to Cassandra. Why is this happening? Why are companies with solid IT structures and internal knowledge shifting, not only to a different paradigm (Read: NoSQL vs SQL), but also to completely different software? Companies don’t simply move to Cassandra because they feel like it. A drive or need must exist.

Thursday Thought: Boredom

Do you ever get bored? I do.

What do you do when you're bored? I eat. I think. I watch.

Sometimes I play on my phone. I whip it out, play some quizzes, read some feeds, send a text.

What I prefer to do is watch the world. There's plenty going on, I walk through a nearby bush regularly and sometimes it's almost like I'm absorbing pleasantness, contentment.

Check out What Sauron is saying about Oracle

Over past year we have been (hopefully) hearing about Oracle Big Data SQL. This is a new(-ish) option from Oracle that allows us to run our SQL queries not just on the data in our Oracle Database but also against NoSQL databases and Hadoop. No extra coding is needed, no extra formatting is needed, etc. All the hard work in connecting to the data in this systems, translating it into executable code on these systems, executing it, capturing the results and presenting the results back to us sitting in our schema in our Oracle Database. How cool is that.

Estimating Apex Development

You’ve finished the design for an Apex application, and the manager asks you “when will you have it ready to test”. You resist the temptation to respond snarkily “how long is a piece of string” – which, by the way, is often the only appropriate answer if they ask for an estimate before the design work has started.
