Cause oracle is 4 times more labor intensive?

They have 4 times more unnecessary features?

I've just waisted half a day researching why my database hangs. Printing pstack indicated some semahores waiting, etc, etc. Finally 10046 trace revealed that it waits me to manually switch archive log! I unintentionally turned on archive because I was not able to offline a tablespace without turning archive log -- oracle error explicitly requred me to do so. Unlike other parameters, archiving mode is not listed in init.ora, but still persists through database shutdown, who might expect it? Received on Thu May 08 2003 - 14:08:14 CDT
