this issue was discussed during the tuning round-table last week ( just to keep Paula jealous;)) and at some point someone (Anjo, as far as I remember) in the room sad that on some situations the only thing that dbms_stats does is - analyze compute ........ . But I guess that besides that you are on the right track , it works better rgds

This is an old and probably stupid question, but Im on a new project and they are using Analyze. Im trying to get them to switch to DBMS_STATS please let me know if my argument is correct. Need to be able to articulate this adequately.

DBMS_STATS is faster
the statistics gathered are better
you can use histograms and I believe I may have identified some areas where they would be appropriate.

anything I missed? Ive pointed them to asktom also. Any other good sources to point them to?
