Select value from DBA_HIST_SYS_TIME_MODEL where stat_name='DB time' Thanks, Lei Zeng Sr. Oracle DBA Yahoo -----Original Message----- From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Jeffery Thomas Sent: Wednesday, September 09, 2009 6:14 PM To: ORACLE-L Subject: AWR - DB Time by User Trend Report? Hello all - I'm composing a few historical reports from the AWR, using this link as a guide: http://www.oracle.com/technology/products/manageability/database/pdf/owp _awr_historical_analysis.pdf One report I'm trying to develop is a "DB Time by User" trend report - if at all practical - but I'm having difficulty determining which DBA_HIST* tables are relevant with respect to aggregating by the user. Would anyone a similar report or at least, what tables may contain the necessary information? Thanks - Jeff -- //www.freelists.org/webpage/oracle-l -- //www.freelists.org/webpage/oracle-l
