Now for some logrolling at its finest. I thought I’d try to help Sheeri, the MySQL She-BA, spread the word about the 21st episode of her OurSQL podcast as it is the second of a two-part interview with Pythian pres. Paul Vallée. The topic is, “The Rise of the MySQL DBA.”
I am sad to report that my RSS feed for oracle-wtf definitely made me say WTF! but not in a good way. Actually visiting the site confirmed my suspicion, it’s been hi-jacked by a splogger.

Yes, I know, this subject of detailed extent map of the datafiles is a rather old one, and a few different solutions have been provided by several professionals, including the famous Tom Kyte. But none of the answers I found did exactly what I wanted, and therefore, I chose to write my own solution. OEM does provide this, but for a price — the Tablespace Map is part of the Oracle Tuning Pack — and I like the free stuff and the extra flexibility I have using queries.
come from a MySQL background, and I have been given the challenge of learning Oracle. So I decided to install my own Oracle database, which I’ll be free to destroy in every way I can think of… and of course, free to bring it back to life.

Last Friday, a customer paged me to say that they could not open an Oracle 8.0.5 database after the RAID array crashed. It turned out that this database was in NOARCHIVELOG mode and there was not even a cold backup. Furthermore, they didn’t even have a database export. it was definitely the time to recall Kurt Van Meerbeeck and his all-time-hit tool — the DUDE. DUDE stands for Database Unloading by Data Extraction. The client was very impressed by how we were able to recover from a deadly situation like that, and it was only possible thanks to the DUDE and his creator: thanks a lot Kurt.
Like an invincible psycho with a knife, Log Buffer is back, with a Friday the 13th issue (“Larry’s Revenge!”). Daniel Fink of OptimalDBA is the lucky one to do this 53rd edition of the weekly review of database blogs.
Let’s focus on what 11g is all about. The main message I got is that Oracle 11g is the consumer release. According to Mr. Phillips, what this means is that Oracle has listened to its clients and has worked in the areas that the consumers needed the most. The fact that Ari Kaplan, the president of the IOUG, was on stage during the launch speaks for itself. As for what’s new in 11g, three major features come to mind…
