Hello Folks, We have moved our database via the exp73 export utility from 7.3 to 9.2.0.3. Only the relevant schema was imported. As an initial backup I made an export using export utility for 9.2.0.3. In the log file is the following warning... EXP-00091: Exporting questionable statistics. This is for all the tables in from the old 7.3 system. Does anyone know to "fix" this? Will DBMS_Stats.Gather_Schema_Stats fix this? Many Thanks Denham -- //www.freelists.org/webpage/oracle-l
