Subject: RE: Not quite fluff - dbms_stats
Or just identify which tables/indexes - and partitions/subpartitions,
forgot those in my diff sql - exist in the stattab table that do not
have a
recipient table/index/etc in the target system and delete those rows
from
the stattab table. Then you can do a schema or database import.
But even the scripting is not too bad:
begin
for r in (select owner, table_name from dba_tables) loop
begin
dbms_stats.import_table_stats(r.owner, r.table_name, ...
cascade=>false);
exception when others the null;
end;
end loop;
for r in (select owner, index_name from dba_indexes) loop
begin
dbms_stats.import_index_stats(r.owner, r.index_name, ...);
exception when others the null;
end;
end loop;
end;
In effect that's what the imp_database/schema_stats does for you, so the
performance should be comparable.
