Detailed Analysis (Oracle) 

If the Alert Monitor indicates that the database has potential performance problems, you can analyze the database in more detail.

Use the analysis functions available from the main screen of the Database Monitor Database Performance Analysis ( SAP/Oracle Database Monitor: Main Screen).

All these functions provide numeric information on the database. A lot of the information can also be displayed graphically. You can access the most important analysis functions by Detail analysis menu. You will find a list below of some of the diverse analysis options - these are options which, from SAP’s experience, are frequently used by customers.

Not all the analyses offered by the monitors are included in the list. Functions that you do not normally need are not listed. These functions are mainly used by the SAP Service & Support to analyze your R/3 and database system.
