本课基于Oracle DSI405学习Oracle DB Performance Diagnostics 。 DSI是Data Server Internals的缩写,是Oracle公司内部用来培训Oracle售后工程师使用的教材。
7、Steps for a Production DB Define the problem Examine the host system and Oracle statistics Consider some common performance errors Build a conceptual mode Implement and measure the change Check that the bottleneck has been resolved 8、Tuning Methodology ...
Transient performance problemsare short-lived and do not appear in the Automatic Database Diagnostics Monitor (ADDM) analysis. ADDM tries to report the most significant performance problems during an analysis period in terms of their impact on DB time. If a particular problem lasts for a very sho...

The objective of database tuning is to reduce DB time. In this way, you can improve the overall response time of user transactions in the application. 2.1.2Wait Event Statistics Wait events are incremented by a session to indicate that the session had to wait for an event to complete befor...
一般,oracle相关的进程,后台进程等都是属于oracle用户。 AI代码助手复制代码 异步IO asynchronous写磁盘的时候,不等写完就返回。操作系统设置DISK_ASYNCH_IO,如果设置了异步IO,把db_writer_processes设置成1,不要设置dbwr_io_slaves。Aix 可以用lsattr –E –l aio0来查看异步IO。
This tuning recommendation feature can also catalog queries from least to most efficient, advising you on which ones to tackle first for faster and more efficient troubleshooting. Theanomaly detection powered by machine learningin SolarWinds DPA can also help you improve your Oracle DB performance mon...
