ora_dbw0 memory usage

[fmorel]

Hi all!

A database process, ora_dbw0_MYSID uses a lot of memory on my system (far too much compared to the database size).

Do you know what this process is? What initialization parameters can modify this process memory usage ?

Thanks a lot for answers!

It's a DBWR for MYSID instance.
Pls define "lot of memory" in my system it uses 2 Mb.

A lot is 205 Mb.

Database size is around 5GB

and SGA is

select * from v$sga

NAME VALUE
Fixed Size 103396
Variable Size 87531520
Database Buffers 396623872
Redo Buffers 180224

... but DBWR has nothing to deal with SGA...

Is it a bug?
