As well as the structure of the table... What (or how many) indexes are on
the table? Have you tried just analyzing the indexes, or perhaps just
table data?
Also, since I don't have a convenient environment to test this out... Can
someone please confirm what happens to a global index when only a partition
is analysed? Just curious really.

Dear gurus !
We are trying to analyze a table partition (estimate 2 %) and it takes
forever.
analyze table ... partition (P20021022) estimate statistics sample 2
percent;
For instance, select count(*) from the same partition takes 10 minutes ,
but
the analyze takes literally infinite amount of time , once i left it to run
for half a day and killed it since it did not finish.
Even when i do analyze ... estimate statistics sample 100 rows; , it takes
almost 2 minutes to ananlyze 100 rows.
Any ideas ?
It's Oracle 8.1.6 on an expensive 6 CPUs HP machine with EMC storage.
Thanks a lot in advance.
