Home -> Community -> Mailing Lists -> Oracle-L -> Re: analyze table takes forever
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.

Please respond to
ORACLE-L
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.
