I want to create an insert trigger on MySQL which will automatically insert the record into an Oracle database. I would like to know if there are people that have experience to share on this topic.
Cheers

Invoke a script as is done in this example that calls the Oracle code.
Note: you lose support for transactions (there will be no built-in rollback for the Oracle database) when you perform this type of cascading, and you also will take a likely very large performance hit in doing so. The script could turn around and simply call Java code or some other executable that invokes your some generic code to insert into Oracle, or it could be a raw query that gets passed arguments from the script.
This is almost certainly a bad idea because of the odd side-effect behavior, but it’s one that can be implemented. I think that you would be much better off having the code to do this against two different
DataSources (in Java/.NET speak) rather than have a hidden script in a MySQL trigger that screams unmaintainable, as well as hidden failure for future developers.
