Roll your own Big Data Appliance

The chances of getting my hands on 18 servers each with 12 cores, 48g RAM and 84T storage each all connected by InfiniBand are not that great. But I can play with the software, and so can you. Unlike Oracle’s Exadata, almost every software component that is available on the Big Data Appliance is also available for download. So, lets roll our own Big Data appliance!

Oracle Database Appliance Now Supports All Monitoring Agents

I was browsing My Oracle Support today, and came across note Note 1415713.1 which talks about updates to third-party monitoring agent support. According to the note and associated FAQ, as of February 15, 2012, all third-party monitoring agents are supported on the Oracle Database Appliance (ODA). This means that the previously-published list of supported third-party agents on OTN no longer applies. The biggest benefit to the policy change will be for people who use in-house or open-source monitoring tools like Nagios or newer replacements.

Log Buffer #260, A Carnival of the Vanities for DBAs

Nothing pleases the technology bloggers more than the moment when somebody thank them for a helpful blog entry. That is one of the many awesome advantages of the technology blogs. In database arena, the developers, DBAs and evangelists are sharing their tips and tricks through their blogs and this Log Buffer Edition is projecting them…

Embedding Perl in SQLite

The extension system is good for anything written in C. So, in theory, I could — probably shouldn’t — but I could write a thin wrapper for a Perl interpreter. At that point, I had no choice. The idea was so preposterous, I had to try it.

From the Blogs to Your Mailbox

What if I found a way to get the blog entries, and plop them on mailboxes on my mail server? That would take care of ubiquitous access. And since I would have control on the software, I could probably manage to filter out dupes. I sat down and began to hack on this. The result is mailfeed (clever project name pending). I’m still not sure if it’s a good idea, but at least its execution showcase how much niftiness can be crammed within 144 lines of code. But let me show you…

Performance Optimization for MyISAM Compressed Tables

Database performance optimization is a significant part of the ongoing service we provide for our clients. We recently found that a client had a query they performed regularly that was drastically slowing the system as a whole, and we investigated to see if we could help them resolve the issue. The symptoms were confusing: though the server configuration was…

A First Stab at SQLiteTAP

My first stab at SQLiteTAP is on GitHub. I’m writing it as a SQLite extension, so I had to brush up very rusty C skills. But after a few hours pouring over the documentation, and poking here and there, I have a working implementation of ‘plan’ and ‘ok’. Nothing earth-shattering, I’ll concede, but a nice start nonetheless.

Conference 2012 Battle Plan

This blog entry is light on technical content and heavy on “about me” stuff. So unless you’re interested in the hot spots where to dispatch ninja assassins to take me down this year (or perhaps just where we might cross paths and shake hands), feel free to close this tab.

Looking for BigData, NoSQL or Exadata slides?

It was fun presenting today at Portland and I’m looking forward to continuing my user group marathon at Denver tomorrow and on Thursday. Since many people asked me where they can find my slides, and I predict that few more will keep asking about them over the next few days, I uploaded my Big Data and NoSQL presentations to SlideShare. You can find them here:
