Hi! > Hi Tanel which is Method F? Method F is a trial-and-error method of changing random parameters and creating random indexes in case of Oracle performance problems, which leads to lots of wasted time and efforts in longer term and which might cause performance for end users even to degrade, although "all the silver bullets are applied, thus the database runs optimally".
