Hi gurus,

My Production Box has 1Gb Ram with single 933Mhz PIII processor , though the db is not that big (4 GB), the oracle process is taking too much of memory, causing server to slow down on peak times of the day, and even after words, tonight, I looked up the memory which ORACLE.EXE has taken, its almost 900 MB, why is that so ???
The last restart was a month ago as far as I remember, is this an OPERATING SYSTEM tuning problem or database tuning is required? MY pagefile size is almost 2 GB, but the STATISTICS show that only 4-5 MB of physical memory is free, means the most of the physical memory is used in ORACLE processes,
The sga size is following,

SQL> select * from v$sga

NAME                 VALUE     
-------------------- ----------
Fixed Size                75804
Variable Size          90701824
Database Buffers      655360000
Redo Buffers              77824

If db tuning is needed, from what point I should start, Also, I haven't analyzed the schemas from long, The occasion DEAD LOCK problems also show up,

Can anybody shed some light, where the choke point is ???

Help and suggestions welcomed,
Thanks in Advance,
