spViewer Standard is an Oracle DBA tool that provides a more convenient way to report and analyse performance data for over 100 performance metrics gathered by Oracle AWR Utility. AWR Viewer is the tool with GUI interface with several useful features which help an Oracle DBA to work with Oracle awr performance data more quickly and productive. It allows Oracle DBA to see how Oracle Instance's performance metrics change with the course of time. That is, awr Viewer takes the performance data stored in the Oracle AWR tables and presents it as graphical charts or trend reports. Experienced DBA's know that measuring performance data over time can provide great insights into hourly, daily, and weekly "signatures". These signatures, in turn, tell the DBA when specific database tasks are stressing the database. Thus, an Oracle DBA can see and analyse the various performance trends and able to decide what administrative actions to take to maintain Oracle Instance's performance at a given level.Furthermore, spViewer Standard is able to generate alerts, store them in database and notify an Oracle DBA by e-mail if some performance metrics exceed alert limits set by DBA.
