A Few Thoughts on OSCon and the Open Source Community

This past week I attended OSCon, the annual conference for open source’s true believers. And there was a religious fervor in the air, particularly from the point of view of someone more accustomed to Oracle conferences. The companies generating buzz were the small companies built around development of their own open source products. There are a surprising number of them out there, especially relating to multiple forks of a popular product like MySQL or Hadoop.

Varys’ Little Birds

One of the great joys of Perl and CPAN is how it allows you to stand on the shoulders of giants. By picking the right tools, applications that are not that trivial can be built in a matter of days, if not hours. The goal of today’s little project is to demonstrate that very thing. Grab a helmet and put your mouth-piece on, for this time I aim to do nothing other than blow your mind to awestruck smithereens.

Log Buffer #278, A Carnival of the Vanities for DBAs

Some parts of the world are going through winter in swing while others are savoring summer (or suffering through it!). This variation in weather is beautifully in-sync with the variety of blog posts sprouting all over the web, especially regarding database technology. This mixed flavor of database blogs is captured once again by this Log Buffer Edition.

How to Deal with Jobs Belonging to Other Users

This is not the first time I have run into this issue – in the past I (and who knows how many more Oracle DBAs) have had to deal with handling jobs from a different user, which usually ends in a big error. The answer to my prayers was the undocumented dbms_ijob package.

DBD::Oracle 1.46 and 1.47_00 Hit CPAN

After a little more than two weeks of soaking without any issues (yay!), version 1.45_00 of DBD::Oracle has been promoted to general use as v1.46.

And because some contributors have been very busy in the meantime, the next trial version, v1.47_00, is also already on its way to CPAN. This new version offers a few bug fixes (more details in the changelog excerpt below) as well as a rework of the platform-specific troubleshooting guides as POD documents. As usual, it’ll be left around for a minimum of two weeks before it gets promoted to v1.48. Happy upgrade!

Minimal Downtime Option for Upgrading Oracle 9i/10G Databases to 11G

Often, a hardware is updated at the same time as a database version. In such cases, we migrate a database from an original location to a new server upgrading the database version and sometimes changing operational system. If this is your situation, you can use the upgrade process to minimize the system’s downtime to 1 hour, independently from the size of the database you migrate.
