Lisa,

Wow, you might be saving me from peril right now. I have tested this with a small set of tables with no problems (in and 8.1.7.4 instance). I'm preparing to go 'schema' wide in the next week or so for further testing prior to implementing in production. I'd be very interested in more details of your problems in 8.1.7.4 and of course I'll post reports of testing to the list as well.

For starters, here is the code I use to obtain a list of 'stale' qualified tables:
( For proper credit, I think I got this from asktom.oracle.com)

set serverout on size 90000

declare
l_objList dbms_stats.objecttab;
begin
dbms_stats.gather_schema_stats
( ownname => '&1',
options => 'LIST STALE',
objlist => l_objlist );
for i in 1 .. l_objlist.count
loop
--dbms_output.put_line( l_objlist(i).objtype ); dbms_output.put_line( l_objlist(i).objname ); end loop;
end;
/

And the code to gather stats:

set serverout on size 99000

begin
dbms_stats.gather_schema_stats(

        ownname=>'&1',
        options=>'GATHER STALE',
        cascade=>TRUE,
        degree=>8,
        granularity=>'ALL',
        method_opt=>'FOR ALL INDEXED COLUMNS SIZE 1'
        );

end;
/

Thanks,
Darrell

Hello everyone,  

Is anyone using dbms_stats and gather stale or gather auto in 9.2? I'm
trying to use dbms_stats gather schema stats with the stale option and it just isn't working in 8.1.7.4. This is documented on Metalink. I'd
love to hear from someone else if this is fixed in 9.2 and if it can be
reliably used.  

Thank you
Lisa Monkey.
