QUESTION POSED ON: 17 January 2008
Is there any way to create an insert/update trigger in Oracle to update tables in SQL Server 2005? I found an article on using Oracle Heterogeneous Services, which says we can access the SQL Server locally. Is that recommended?

>
As far as I know, Oracle Hetrogeneous Services is the only direct way of updating non-Oracle systems. As you may know, this technology allows non-Oracle systems to appear like removed Oracle databases and they are accessed via a database link. Therefore, you may be able to call a procedure in SQL Server and issues related to the distributed transaction should be taken care by the Transaction Service.
