May have something to do with bug 2649728, which I just heard about for the first time no more than 10 seconds ago.

I have never had good luck with DBMS_STATS. It seems that the old analyze runs much faster.....  

Runs in 45 seconds:

analyze table log_trans partition (log_trans_20030104) estimate statistics sample 5 percent;  

Takes over 2 hours:

execute dbms_stats.gather_table_stats(ownname => 'LDGADMIN', -

                                      tabname => 'LOG_TRANS', -
                                      partname => 'LOG_TRANS_20030102',


-

                                      estimate_percent => 5);

Am I missing something? Aren't both commands the same?  

Thanks,

Tom
