one of our busiest days it came to an extent where the cpu idle time came to
0%.
The only option was to enable Cached Quick I/o which is now causing the
reverse, it causing write complete waits and this file open event,which

Hi Arun,
Foreground processes open the datafiles only when they need to read from them
(or write to them in the case of a sort). The 'file open' wait event represents
the opening of and typically the first I/O operation against that datafile,
however, sometimes a few extraneous I/O operations
Can Somebody please explain to me what this event is , I am not able to find
good documentation on this issue.
