Hi,
I have a situation in which the application vendor is asking to increase the
buffer cache size to resolve a performance issue, pointing to the advisories
from the dbconsole.
Although I have already proved via tracing that the problem is mainly in the
queries and schema design, and that even if we cached everything we still would
not be able to get the requested response times, they are still pointing to the
advisory.
All this asside, it made me wonder what would be a good method to verify if the
buffer cache is correctly sized?
Same question for the shared pool.
