Distributed Transaction Framework attraverso i servizi web

Sembra che tu voglia utilizzare il protocollo commit a due fasi . Molti hit tornano da una ricerca su google, quindi troverai molte cose da ricercare.

Ecco una breve descrizione dal sito di Wikipedia.

In a "normal execution" of any single distributed transaction, i.e., when no failure 
occurs, which is typically the most frequent situation, the protocol comprises two phases:

    The commit-request phase (or voting phase), in which a coordinator process attempts 
to prepare all the transaction's participating processes (named participants, cohorts, 
or workers) to take the necessary steps for either committing or aborting the transaction 
and to vote, either "Yes": commit (if the transaction participant's local portion 
execution has ended properly), or "No": abort (if a problem has been detected with the 
local portion), and
    The commit phase, in which, based on voting of the cohorts, the coordinator decides 
whether to commit (only if all have voted "Yes") or abort the transaction (otherwise), 
and notifies the result to all the cohorts. The cohorts then follow with the needed 
actions (commit or abort) with their local transactional resources (also called 
recoverable resources; e.g., database data) and their respective portions in the 
transaction's other output (if applicable).

Questa è una classica transazione distribuita.

Per prima cosa blocca su ciascuno dei suoi servizi web, quel blocco bloccherà tutte le transazioni sui record targetizzati. Una volta che tutti i blocchi sono stati protetti, emettere il comando delete.
