spawning a seperate process for a long running stored procedure from vb.net??

Im writing an SSIS script task using VB.NET. I'd like to be able to
initiate an oracle stored procedure call for a process that will run
for 8 hours, but I don't want my process to wait for it finish. In
fact, I'd like the ssis job to terminate after it launches it.

How can I do this using vb.net/ado.net?

How can I later electronically locate and track that process?

Thanks for any help or information.
