Calculate the buffer pool hit rateIdeally, the buffer pool hit rate is above 95% and the formula is as follows:(1-(Buffer pool data physical reads + buffer pool Index physical reads)/(Buffer pool data logical reads + Pool index logical

right-clicking instances and selecting add . To delete an instance of the DB2, you can execute the command de>db2idrop In summary, in Oracle, you can use the Database Configuration Assistant to create, modify, start, stop, and delete instances, while in DB2 you can do the same thing with the control Center GUI.

management process. If the DB2 controller is enabled, the process takes a snapshot according to the time interval specified in the controller configuration file and checks the snapshot against all configuration rules. If a rule is violated, the specified action is taken. All Db2panic emergency agent procedures. If the agent on any database partition is not idle, the process handles some urgent requests.
