Viewing History Information 
You can view history information – or “snapshot” data – when using many of the submonitors in the SAP/Oracle Database Monitor. You can specify a “since” and an “up to” date and time.
Starting with Oracle 10, the history information is written using only the Oracle Active Workload Repository (AWR). For Oracle 9, the mechanism for writing history information remains the same as before. For more information on the changes to history information, see SAP Note 1080813.
