Hi!
Do you have any LOBs defined with
the nocache nologging attribute ?
This was what I initially thought would be the problem, but then I thought,
in case of nocache lobs you should see direct path writes (lob) a lot...

Please see the official ORACLE-L FAQ:
Mladen,
Here I will humbly disagree with you. It is not fault of Windows but the
person who created the database and defined tiny size log files while
creation. If he used custom database option he can define whatever size he
wants. These options are same for both Windows and Unix.

WE have ORACLE 9.2.0.3 database run under Win2000. I
run statspack and found Top 5 timed event. Look
like control file parallel write and redo file
parallel write take lots time. How to fix?

Increase redo logs to 250M each. You're checkpointing.

How did you determine the size of the logs?
Or are you just guessing that they are significantly
less than 250m?
Could just be a very busy database that needs redo
and controlfile on faster disk.

Defaulty Windows installation usually creates log files of 20M. The
person who posted the problem explicitely mentioned Windows platform.
Size of 20M is so small that the database will start to checkpoint
like crazy when you start using it for real. The number that I gave
is my rule of thumb.
Defaulty Windows installation... Hehehe;-)
