En route we got an ECAM advisory for low oil quantity on the number two engine. We contacted Dispatch and [Operations] to advise and a joint decision was made to divert to [a suitable airport]. We initially declared 'PAN PAN'. Shortly thereafter we observed a decrease in oil pressure which ultimately resulted in an ECAM low oil pressure advisory. We conducted the ECAM action which resulted in shutting down the number two engine. We followed up with the QRH and all other appropriate company SOP's and proceeded to [the alternate airport] making an overweight landing. There are no causal factors that I am able to apply to this event other than a mechanical issue.
