I am an enterprise DBA for SQL Server and MySQL. I will post various "gotchas" encountered in live production environments. The names of the guilty will be omitted to protect the not so innocent. Life as a production DBA is always challenging and sometimes much more exciting than one would wish for. It seems that something comes up every week where searches take significant effort to craft the right question to get the desired answer. I will keep this blog short and point to the detailed explanations.
