fire off multiple dbms_stats.gather_schema 2004-07-08 - By Connor McDonald
Something like
procedure DO_SOME_DBMS_STATS(p number, maxparallel number) is
begin
for i in (
select * from (
select mod(rownum,maxparallel ) r, segment_name, ...
from dba_segments
order by bytes
)
where r = p ) loop
dbms_stats.gather_table_stats(....)
end loop;
end;
for i in 0 .. maxparallel-1 loop
dbms_job.submit( 'DO_SOME_DBMS_STATS( '||i|| ', '||maxparallel|| '); ')
end loop;
