What do you usually do on a Friday night? Go out with your friends, finish some work, or just watch TV and then go to bed? Well, today I spent my Friday night in the office (like real DBA’s). Why? Well, our unix admin change the configuration of the servers and of course the DBA also has to check afterwards, if everything is right with the databases. And it was a good decision to came. Actually all database were down except of one. And it was a good chance to patch one of them. Well, now it’s 12:09 AM (on a Saturday morning), the unix admin is still working, but I’ll now drive home and go to bed.
