Walter,

Couple of other areas to watch while DMLs are being issues against this table are: LGWR and DBWR statistics and activities. Based on DBWR/LGWR statistics, you may need to tune these parameters.

Hi,

I have a table that is going to have a large amount of inserts, updates and deletes performed against it daily. Approximately 1,000,000 transactions per day (some single-record, some multi-record). The table is ~100Mb in size.

I'm looking for some suggestions on what I can do to have the most optimal I/O for the table. I've been doing a little reading about buffer pools. Is assigning this table to a KEEP pool a practical approach or is that not going to buy me anything because DML is involved? Does anyone have any other suggestions?

Unfortunately, I can't put the table on a dedicated disk and I am stuck with Raid-5 currently.

Any suggestions would be appreciated.

Thanks in advance!
