Hello SQL forum readers,

I have a customer using Ms SQL Server 2000 SP3 installed on optical RAID-5
Disk Array (IBM Fast200 SAN).
After a disk failure his production db was corrupted and since the failed
disk was replaced, cust. restored a valid backup
in order to support his business operations (with one day transcations
loss).
We have dome a lot of troubleshooting and investigation (traces, logs,
dumps) in order to identify what caused the corruption.

But now, cust. faces low performance problems.
I have already suggested to use additionally the following options :
A) Auto Options:
Auot create statistics
Auto update statistics
B) Recovery Options:
Recursive Triggers

I would be much appreciated If I could have any advise regararding any
additional db option setting that could assist :
a) What about Quoted Identifiers or other SQL option?
b) What about Torn Page Detection (recovery option)
c) Any other cursor options that could assist?
Is there additional MEM/CPU overhead by enabling those options?

I have also advised cust, to execute the command SET SHOWPLAN_ALL in order
to gather details abour executed statements
Anything else I can do?

Any advise will be much appreciated.
Thanks in Advance

Regards, Nick Dakoronias
