Welcome, readers! It’s time for another update to our series of posts on installing Oracle on Ubuntu Linux. In this edition, we’ll be installing Oracle 11g R1 on Ubuntu 9.04, both 32-bit.

This time, I’ve used VirtualBox to run a virtual machine (VM) to perform our work. (Virtualization has a number of advantages; in this case, I made several trial installs, trying different combinations and configurations. Having a pristine, basic set-up accelerated the whole process, since I didn’t had to reinstall from scratch on every new attempt.)

You might want to review the previous editions of this series, as there are technical references on this text fully detailed on previous posts. See these HOWTOs for Ubuntu:

• 8.10 – Intrepid Ibex
• 8.04 – Hardy Heron
• 7.10 – Gutsy Gibbon
• 7.04 – Feisty Fawn

Since we’re installing on a VM, we’ll be using Ubuntu 9.04 32-bit Server edition, , so let’s download it and check the MD5sum:

Download Oracle Database 11g Release 1 (11.1.0.6.0), and verify the provided cksum:

Just a quick post to get myself back into blogging mode. Recently in IRC (#oracle on freenode, to be precise), a fresh face asked if the Block Change Tracking file ever shrinks. She had been worrying about the file in her instance continuing to grow. A number of us speculated (non-BAAG!) that perhaps taking an RMAN backup would somehow purge the file of what it was keeping track of, and then the magical Oracle fairies would promptly resize it for us. Needless to say, I was hesitant to take this theory forward with Alex Gorbachev aware of my home address.

After setting up Oracle 10.2.0.1 on a nice VirtualBox image
(more on that in another post) running CentOS 5, I began to do some reading. For some reason, actually reading the official tahiti docs was last on my list. A search of the 10gR2 docs quickly yielded this (from RMAN Incremental Backups):
