Maybe some of your databases were created in 10.2.0.1 and then upgraded to 10.2.0.4 while others were created after the upgrade to 10.2.0.4? I just checked one of my DBs that was recently upgraded from 10.2.0.2 to 10.2.0.4 and I also show one record for each version, e.g.: SQL>select version, highwater from dba_high_water_mark_statistics where description = 'Number of User Tables'; VERSION HIGHWATER ----------------- ---------- 10.2.0.2.0 71099 10.2.0.4.0 71107 Regards, Brandon ________________________________ Privileged/Confidential Information may be contained in this message or attachments hereto.
