RE: Oracle heterogeneous services - Experiences anyone?

If you so a search on the archives for Oracle -l you will see my woes.....

I would open two connections instead of going down this route instead IF your SQL Server isn't very reliable..... We have actually staled and brought down our Oracle doing this. BUT our sql server app is not stable.
Try to push stuff via DTS or sqlldr as well.

We paid 8.000 for data direct drivers to do this and I am happy to say we are off of this in less than one year.

We also experience memory leaks. If a connection hangs between the two, kill it off on the sql server end.

As you see .... I am not a fan.

My 3 cents worth.

Subject: Oracle heterogeneous services - Experiences anyone?

Dear List Members!

A collegue of mine not having access to this list=20 needs to exchange data between an Oracle 9 and a Microsoft SQL-Server = database.=20
As far as I know he needs only to access SQL-Server data from Oracle. He would like to know about the experiences people made using Oracle heterogeneous services for that purpose.

I would be thankful if anyone liked to share his/her experiences, and knowledge about reliability, performance,pitfalls and other = "special"=20
features in a production environment.

Thanks in advance
