Installing Oracle 11g on Ubuntu 8.04 LTS (Hardy Heron)

After our last post about installing Oracle 11g on Ubuntu 7.10 (November, 6th), and considering Ubuntu 8.04 LTS was released on April 21st, I spent some time reviewing and putting together this new HOWTO for the installation. Please note: I’ve used the x86 server version of Ubuntu 8.04, but the same steps should work without any problems for the Desktop version. Also notice that this whole procedure can easily take over six hours to complete, so don’t complain I didn’t warn you! So, let’s get started, shall we?

MySQL Community Member of the Year Award Musings

By now it is no surprise that I won one of the three 2008 MySQL Community Member of the Year awards. I am going to detail in this blog post the secrets to my success. This year, I thought to myself, “how can I make it so I am not on this stage receiving this award next year?” So here is my challenge to you. I will open source my methods, and in return I will give $100 to each 2009 MySQL Community Member of the Year (in whatever form they want, whether it’s US cash, a $100 gift certificate, a donation to an organization, whatever).

How to Make an In-Database listener.log File

Ever wished the listener.log file was a table in the database? Wish no more! About three years ago, I sent this recipe in an email to my co-workers. Just recently, Shakir re-sent it after using the method in an emergency. Since it seems to have proved its value, I now offer it to our readers. Have a look.

3 Tips on Using dg4odbc on 64-bit Linux

I recently imported the contents of an Oracle 8i database into an 11g database. After following the instructions for a typical setupI set up a database link to a remote SQL Server database, and called it SQLSERVER.. It turned out that dg4odbc has “hard coded” the quotes and this will need to be changed in odbc.ini. I should have looked more closely at the installation instructions — yes, the example shows QuotedId=Yes.

How to advocate for good backups!

I try to do a decent job of advocating for caring about good backups and business continuity strategies in my 7 Deadly Habits article. But this one beats them all, have a look for yourself, it too funny.

Pythian Goodies: The Answer to Free Memory, Swap, Oracle, and Everything

I gave this talk covering the different types of memory, how to monitor memory, and how to optimally use it with Oracle at the UKOUG, I have since received requests to post the slides online. Instead of just posting the PowerPoint I took some time to give the presentation again (internally here at Pythian) and this time we recorded the session and are posting it in a variety of formats. This is a bit of a departure from the typical Pythian Goodies, in that it is scripted, and there is a lot of content here in the whitepaper.
