If you're testing performance, wouldn't you want your test environment to
mirror what production would look like? I would think that a performance
test of a
NOARCHIVELOG db would have limited validity for an ARCHIVELOG mode
production, especially with 100M log switches every two minutes.

Hi,
We never worked on large databases but we have to test our application for
scability and performance test.
It will be great if DBA handling large databases give some input on
following :
Environment is 9i on SUN 2.8. Database size will be about 375G.
1) In our testing environment log file switch is occuring every 2 minutes.
The size of log files is 100M .
What shold be the size of log files in Performance testing --- 500M or
1G . Is there any drawback in using large
size of log files. For performance testing we will be running in
noarchive log mode.
2) Two of our table sizes is 175G and 160G. We are partitioning both the
tables into 10 partitions. What should be the
ideal datafile size and initial extent size. Is there any drawbacks in
using big datafiles. We always used about 2G
file size for small databases.
3) We will be using locally manages tablespaces . which option is better
for large database Uniform size or Autoallocate.
Thanks
