Re: BUFFERS setting

Buffers are good, the number of mod bufs may not tell you everything. It all depends on the ckpintvl and the lru settings , if the lru's are set low they will constatly clean your buffers so your mod # of bufs will be low . More bufs = better cache. 40mb of bufs is not a lot. Depends on how many users and what they do. Is your appl doing a lot of insert/update/delete or is it mainly reads.
