Thanks for the ideas. We want to avoid having the Cloud instance have a
direct connection to our database, hence why we want to push instead. Plus
that works out better for our users, when they are done processing orders
they initiate the send to the cloud vendor. This will be a multi day event
to push to MSSQL.
I've been testng with 5000 rows, right now it is taking 2.5 minutes before
it was 6-8 minutes. I believe the latency to OCI is fluctuating,
currently I am getting 14ms ping times, however it is early in the morning
here in California as I am working on a 19c upgrade. We've had ping
latency in the upper 60ms ranges and we've experience a lot worse around
8:30am with packet loss.
I was thinking the same thing about a Perl or Python script "might" be
faster. Any one happen to have a sample of that?

Hello,
Have you tried doing a pull from the MS-SQL-Server side?
How much data in the table?
How "far" apart are the Oracle and MS sides?
How you tried sending one row and timing that?
Look at the MS-SQL-Server funtion OPENQUERY.

Frank

I found that just a
insert into table@mssql
select * from table;
Returns ORA-02025: all tables in the SQL statement must be at the remote
database
I am trying out the SQL Server Gateway driver from Oracle because the
documentation looks like it would work with the Remote Insert Rowsource
https://docs.oracle.com/en/database/oracle/oracle-database/12.2/gmswn/database-gateway-for-sqlserver-features.html#GUID-513FBA3C-3458-4129-93E4-38DB2DF97F7A
However I get the same error. Does anyone know if this should work?
We've converted it to a PL/SQL loop inserting row by row but 5000 rows is
taking 8 minutes. Oh and the funny thing is that this SQL Server instance
is running on Oracle Cloud Infrastructure.
Any other ways you can think of to do this quick? 8 minutes is killer.
Thanks,
Jeff
