Value of Oracle AWR Shutdown: An Analysis(oracle关闭awr)

Nowadays, Oracle AWR (Automatic Workload Repository) has been widely used in the IT industry. The AWR Shutdown is a component of Oracle AWR. It is an essential metric for performance management and for providing a comprehensive set of metrics for analyzing system performance and diagnosing problems. This article will discuss the value of Oracle AWR Shutdown from three aspects: History data, real-time snapshots and resource utilization.

First of all, the running information of your Oracle AWR Shutdown will provide you the historical data for your database performance. The history data records the average performance of any metric over a given period of time which includes the number of sessions from past DB sessions, the DB wait events and the ratio of transactions. With the data collected, one can determine the overall performance of the system and find out the health of the database and what needs to be improved. The history data also helps in understanding the overall trend of the database and if there is an outlier, it can be acted upon or monitored.

Second, Oracle AWR Shutdown provides access to real-time snapshots and this is a very useful tool for system performance analysis. It captures the state of the database and provides views of the system performance at any given time. This can be used to compare the current performance with the performance of recent times and differences can be pinpointed easily. This is especially useful when trying to determine the current status of the database and the past performance trends.

Third, Oracle AWR Shutdown also records and captures the resource utilization of the database. It can detect the amount of CPU, Buffer Cache and Redo Log space being used. This helps in determining the impact of the system performance and can provide valuable insights when trying to improve the system performance. Knowing the resource utilization could be especially useful when analyzing the overhead of the system and trying to optimize it.

Overall, Oracle AWR Shutdown is a very useful tool for understanding and analyzing the performance of a database system. It provides valuable insight into the historical data, real-time snapshot, and resource utilization of an Oracle database. By leveraging the data provided by Oracle AWR Shutdown, issues can be spotted before it can be too late and consequently increasing the performance of the system.
