THANK YOU!
It Will resolve my problem!
I will read this value and compare with a calculated value (number of
connections, etc) and then set a new value. We are having performance
problems when inserting a large amount of data in a huge table with a lot of
indexes.
We use a default 90 pages in a FB Classic 2.5.1 Windows server. Raising page
caches to a higher value like 200 resolve our problems.
I will read the server memory amount, read our maximum simultaneous
connections and then calculate the 'best' and secure new page caches amount.
Maybe I can except some trouble with this approach?
