asked on

dg4odbc vs dg4msql

I was using a direct database link to an mssql using dg4odbc..

because of performance issues i started looking for alternatives and installed transparent gateway with dg4msql

performance is unchanged. there is no difference in querying time

eg

select * from rmordp@"dblink" where ORDITMNUM = 89129 and ordordqty = 48 and ordseqnum = 24 and ordprcgrp = 8242;

takes 9.351 seconds over the database link.

if i run that same query from the mssql server, it takes less than half a second..


can someone tell me what I am doing wrong or how i should go about getting remote data via oracle in a timely fashion?

when you are querying remotely it also depends on the network bandwidth which you have to communicate between the servers.

please check what is your bandwidth.

its not a bandwidth issue, when i use TOAD for SQL Server to query the sql server directly (without having oracle as a middle man)

my execution times are pretty fast, i am doing this from the same machine that I have sql developer on
