Never seen that one write anything technical that didn't involve calling anyone non-Oakie as a "bad dba". Apparently the only "good dbas" are the Oakies, even though the vast majority of them never had to be responsible and run a production site day after day for years and live with the consequences of their decisions. It's always hit-and-run con-sultancy with those...

Ah well, the mind boggles at so much technical "knowledge" and "ability".
