Hi all,
I will try to assign more memory to shared memory,
say 50M ~ 100M .
I am runing something like that ..
cursor loop 1 cursor loop 2 cursor loop 3 tmp = primary key delete tmp .... insert tmp .... end loop 3
end loop 2 end loop 3
will delete and insert record with same primary key
within a transaction reduce the performance ?
M.T.
