Sometimes I wonder why I do something without thinking. Today at office I suddenly stopped the database server; I was testing something. I forgot for a moment that lots of applications are being served from that server. It took me more than an hour to get it started - just to start the database server. Can you imagine that? I was so tensed. Sometimes linux machine gives me a lot of headache. Now I know the problem and the solution. There's always learning from ones' mistakes. But again I haven't documented anywhere about that scenario. Ugh!
