Title: Safe Database Environment
Hi all,
Can any of you suggest the configuration for a safe, fault proof, and minimum downtime Database environment? (In terms of how many servers, RAID or disk ARRAY or any combination. A minimum configuration is what I am looking for).

based optimizer does, the cbo will hopefully
No - it means you have monitoring set on (at least)
207 tables, and the 207 of them have had a
modification (ins/upd/del) since the monitoring was
enabled.
This data is used to determine whether the stats are
stale or not. Its documented somewhere, but I think
its around the 10% mark before

We have scripts ready that drop the replication on each

We had a discussion about a year ago here and if I remember correctly the
best stripe size is a function of number of concurrent users. With a
small number of users you want a small stripe size so that each read i/o

Can you elaborate on the process that you used to determine the optimal
value for db_file_multiblock_read_count?
We are doing some performance testing on a new generation of our product
with some new databases. We increased our database block size from 8k to
16k (on Sun Solaris 2.6).
Charu,
I guess the error you are getting is Table or Trigger is mutating. and
perhaps you are using an after insert row trigger. This is a common and
expected problem. There are ways to get around it. You have not mentioned
the version of Oracle; I would assume 8.1.7 or later.

I'm just curious whether you also have reset your optimizer_index_
