Hi,
Could anybody help me with
the database link
problem?
I have two databases db_A and
db_B, and link from db_A to db_B.
In the database db_B there is
table B with 1.6 million records.
I created simple test to query data
from the table B via database link (I am connected to db_A)
-------------------------------------
declare
v_record
B%rowtype;
cursor
cB
is
select
*
from
[EMAIL PROTECTED]
where rownum <
20000;
begin
for c in
cB
loop
v_record
:=c;
end
loop;
end;
-------------------------------
I tried to check performance of
data querying through the link, so I had two tests:
- via the link – 19.8
sec
- locally – 1.5 sec
Difference is too large, as
far as I can expect! I have been REALLY
surprised.
At this time there was mostly
no other activity on the network (databases are on the same subnet, at the same
hierarchical level).
Could anybody explain is it
normal results?
Thanks,
