NoSQL Deep Dive – The Missing White Paper

I’m giving a NoSQL overview presentation at MOTS in two days. The conference organizers didn’t ask me for a white paper, so I thought I could get away without writing one. But it turns out that I don’t really feel that I can speak confidently about a topic if I didn’t write the paper. I wonder if other presenters have this addiction too. So I’m posting the paper here for your enjoyment. Feedback is very welcome.

OOW10 Bloggers Meetup Agenda — T-shirts are Back and More…

Counting down. The details are finally organized — this year, we have not one, but TWO great prizes at the Oracle OpenWorld Bloggers Meetup. 1) T-shirt art contest on stylish Pythian designer t-shirts — one lucky blogger will receive an HP X310 Data Vault, generously sponsored again this year by HP. 2) For the best, most creative blog post about the meetup itself, Pythian is giving away an Apple TV. But, there are a few small rules:

AWR Extract and Load

As of 10.2, Oracle supplies two scripts that enable you to extract and load AWR data into another database (even one already running AWR snapshots). You can even take the AWR data from a 10.2 database on Solaris and load it into an 11.2 database on Windows XP (other variations may work…but these are the two versions I have handy). I also took 11.2 database on Linux and loaded it to the Windows database

Emergency Recovery or RMAN DUPLICATE Rerun Just Works!

One of the tasks that I was involved in was 700GB database emergency cloning for an important functional issue troubleshooting. It was 10.2.0.5 (10GR2) 64 Bit database on Linux. To make a long story short I gave the DUPLICATE command a try. I used the comand in this post to start the process. After 4h of the restore process I was horrified (you know how it is to work under time and management pressure) at seeing the following errors

Welcome Dan Fink to Pythian!

I’m very excited to welcome yet another fellow Oakie to Pythian — Daniel Fink has recently joined us in Denver. In the last couple weeks, we have enjoyed having Dan at our Headquarters in Ottawa.

Log Buffer #202, A Carnival of The Vanities for DBAs

Welcome to Log Buffer, the weekly roundup of database industry news. We’re only a week or so away from Oracle OpenWorld. Everyone is buzzing with activity, promoting their speaking sessions and making last minute plans. For all of you bloggers who will be attending, don’t miss the annual Bloggers Meetup, announced recently by Alex Gorbachev. “Count yourself in” if you’ll be joining the gang so that accurate attendee numbers can be provided to Jillian’s to ensure everyone is well fed and watered ;)

Shuck & Awe #12: Hunting for Perl

Holy mackerel, use.perl.org is shutting down! Pudge is changing jobs and, as his now-previous $workplace was hosting the site, he is temporarily shutting down the site. Breath easy, though, the blog entries are not all going to disappear in a puff of smoke — the site will be put in ‘static’ mode for the time being, and there is the possibility it will reappear somewhere else.

How to GNS process log level for diagnostic purposes?

I was troubleshooting a new GNS (Grid Name Services) functionality and noticed a-trace-level parameter in the GNS process string. Unfortunately there is no description in the documentation or MOS on how to change it to generate invaluable diagnostic information. NOTE: I am sure the documentation will be updated in Database 12c version (c for Cloud. For the time being the following should work for you.
