Hi,
The other option that you have is to use Advance Queuing. You can insert the row and a message on a queue within the same transaction. Your procedure will be a consumer of the messages in the queue.
If the transaction that does the insert is rolled back then the message is never placed on the queue and your procedure is never executed. The dequeue of the message is also transactional so if your procedure fails the message will be left on the queue and redelivered. You need to handle the redelivery case is a sensible manner - that is, you do not want the message to be redelivered continually if it is going to fail all the time.
Cheers,
Craig.
