That is it. Thanks for your help. The value is from DBA_HIST_SYSSTAT. I looked there but just scanned through the list for "logical reads' and not "session logical reads". Doh! One followup. I noticed in your example that the percent is over 100% and I have seen that in other reports. Any idea how the sum of the object percentages could be more than 100% of the total?
