In this blog post, I’ll describe a few acronyms – sometimes called buzzwords – that are commonly referred to in HADR projects and implementations (I know I use them a lot when addressing questions regarding HADR.) These acronyms fall under the second P in my PPT for HADR – PROCESS.
The plugin is fairly simple, and (or so I hope) provides a good example of how plugins can wiggle themselves in at the different points of a request’s life cycle. Here’s a step by step guide to writing the plugin.
I give a lot of thought of what makes a DBA awesome as remote DBA, or a consultant. Based on my experience as a in-house DBA working with consultants we hired, on my experience as remote DBA for Pythian and on my observation of the amazing guys working for Pythian Consulting. Here’s the secret: You need to give the customer a warm fuzzy feeling. Here’s what I consider key parts of being effective at giving customers warm fuzzy feelings. Obviously all this applies in addition to being a very proficient technical problem solver.
Dancer touts itself as a lightweight, yet-powerful web application framework. As we will see in a few lines, it sure seems to live up to both promises. Let’s see how hard it was to get my app up and running, shall we?
I was searching oracle.com for some Exadata-related wait events, and noticed some hits popping up from formerly closely-held Exadata documentation. Upon closer look, I found the full Exadata V1 user’s guide. I hope the V2 documentation will be posted soon.
Have your scheduler jobs changed run times since the daylight savings time change? The issue hit me this week. On one client the scheduler jobs had changed run time. The strange thing is the scheduled time was 00:05
A few hours ago, I received a CPAN Testers’s report. The report was a genuine bug (CPANtesters++. Love you guys), and as I made my way to rt.cpan.org to create a ticket to track the issue, I found myself thinking that it’d be nice to have a ‘bug this’ button straight from the smoke report page. You all know where that kind of thinking leads to, right? I didn’t GreaseMonkey’ed a button into the CPAN Testers page (yet), but I did the second-best thing. Namely, a little command-line script that takes a report url and uses it to auto-generate a bug report to the right distribution:
Like any self-respecting geek, I have a small network at home. It’s fairly well-behaved and stable, so I never really felt the burning urge of install a monitoring system. However, as I’ve been bitten by the full partition surprise at 9:30am on a Saturday morning a few times lately, I’ve… come to reconsider that position a little bit. Of course, the right solution would be to install a real monitoring system like, say, Nagios or Zabbix. Trying to reinvent the wheel, and in this case a fairly beefy wheel, would be thoroughly silly. But it’d also be fun and educative. So I decided to do it anyway.
Following up on my earlier webinar Implementing Oracle Exadata – Strategies for Success, I’ll be giving another webinar to present the results of the Exadata implementation at LinKShare. I’ll be talking about actual performance results, our zero-downtime go-live, compression experiences, and performance tuning in an Exadata environment.
There is a new tool came with Oracle 11g Rel.2 that helps to modify options in installed oracle home (Enabling and Disabling Database Options) It is very simple and straightforward utility that recompiles database kernel with different flags.
