Oracle Midlands : Event #11 – Summary

oracle-midlandsLast night was Oracle Midlands event #11 with Chris Antognini.

The lead up to this event was not the best for me. I had been on the verge of a headache all day. By 14:00 I gave up, went home and went to sleep for a couple of hours. It wasn’t great, but it was just enough to take the edge off, so when the time came, I felt sort-of OK to head out for the event. The drive started to convince me this wasn’t the best move, but once I got to the event and sat down I figured I was going to make it. 🙂

Chris did two talks at the event.

The first talk had lots of people’s heads nodding. It’s kind-of depressing, but we’ve all seen, and continue to see, these same things happening again and again. I, like others in the audience, am convinced it is because of the lack of emphasis on database technologies in development. Too many frameworks encourage a hands-off approach to the database, hiding it behind persistence layers that end up doing a mediocre job, at best. Anyway, enough of my rambling. This session should be mandatory viewing once a month for every developer that goes near a database! 🙂

redstacktechThe second session was pretty neat too. I must admit I’ve become addicted to the Enterprise Manager 12c performance pages, so a couple of the things Chris mentioned took me by surprise, including the use of some V$ views that I assumed were part of the Diagnostics and Tuning Pack, but aren’t. I’m purposely going to avoid mentioning them here because I would want to confirm the status before accidentally leading someone astray, but the idea was, query the V$ view and you are good. Query the DBA_HIST_* view and you’ve sourced the information from the AWR, so you need the D&T pack. This definitely *does not* apply to all V$ views, but it’s worth checking out if you don’t have D&T, or you are working with standard edition.

I think the evening went really well. Thanks to Chris for coming to speak to us and thanks to the Oracle ACE Program for getting him across. Thanks to Red Stack Tech for sponsoring the event, allowing this to remain free. Thanks to Mike for doing a great job of keeping these events rolling. Of course, thanks to everyone for turning up after the Bank Holiday weekend. 🙂

Cheers
