How to sync a table between oracle and sybase I have a table in Sybase (destination) that I would like to keep it synced with a table in Oracle (source)

I cannot truncate and populate the table in Sybase because it is used by an application, I can only add new records and update changes, changes only happen to one column.

In my environment I have Sybase, Oracle, SQL Server &amp; .net development

Whats the best, simplest &amp; reliable way to get this task done, should I develop a DTS, a .net app, use linked server of SQL Server or is there a better way?
You could use Oracle Data Integrator for this. See Oracle Data Integrator documentation for a good starting point. If you want you can build this yourself. Change Data Capture can be used. Make a change table in Oracle that receives the change records from the Oracle source and implement the change records to the sybase destination tables.
