than 5 seconds time Ah! It's going to take a look at the execution of SQL! A lot of information was searched on the internet. Finally, make sure to view the SQL execution trace file. SQL execution is a good session,oracle database to support sesion tracking, lock table, and so on. Consider to operate a raw Production database. You cannot track sessions in large numbers. So you choose to track the way you specify sesion, only to see the SQL execution plan that you execute! In the following way

An in-depth discussion on shared pool (i.) Link Http://www.eygle.com/internal/shared_pool-1.htm The setting of shared pool is always a controversial subject. In many articles, shared pool sets up an additional management burden that can lead to performance degradation under certain conditions. So what does the burden of management mean? This article makes a certain in-depth discussion on this content. This article covers only one aspect, and subsequent articles will continue to be discussed
