Oracle Database User Create, Permissions Assign Oracle Database Administrator's Responsibilities (Transfer) General Storage Procedure Writing Yesterday Yesterday Yesterday, Anhui Susun, a customer, the lesson of maintaining maintenance, returning multiple result sets in Oracle, StatsPack is an instance level provided by Oracle TUNING tool. Many DBAs like to use this tool to optimize the database. However, there are some problems with many friends' use in this tool. The following is a simple analysis of several aspects of the problem. About snapshot sample time intervals We know that Statspack's Report actually compares two snapshots (Snapshot, which is the current state of the database). Under normal circumstances, the expert recommends that the snapshot time interval of the StatsPack report is 15-30 minutes.
About TIMED_STATISTICS parameters
Although this is a low-level mistake, it is regrettable, often seeing some friends ignore the parameters. If the value is set to false at the value of TIMED_STATISTICS, it can be said that the collection of things is not very large (I think you will only want to see some instance names, initialize the information such as the parameters). It can even be said that if the parameter is not set to true, performance analysis is not coming.
