Hi list, The partitioning option is disable in Our UAT and QA environment ,db version is 10.2.0.4. I don't know who did this change ,and when was it happened,i query the DBA_FEATURE_USAGE_STATISTICS,and found it is changed to false recently,did a quick search on MOS,to disable the partitioning ,below command is required :make -f ins_rdbms.mk part_off make -f ins_rdbms.mk ioracle , I'm wondering is there a log file to trace this change? I can not see any change on the time stamp of the files in $oracle_home/lib Rgds David-- //www.freelists.org/webpage/oracle-l
