JAP transaction processing failure scenarios

Current transaction processing in Credit Suisse is implemented as a centralized system.Now the possibility of implementing transaction processing as a distributed system on a Java application platform is being considered.In this new environment transactional applications communicate with each other through remote service calls.In order to prevent high transactional complexity, remote service calls are not executed from within the transaction.In case of a failure, atomicity is not guaranteed any more and needs to be reestablished.Reconciliation logic, however, must not be reinvented by each application over and over again, but provided once and for all by the application platform.This master thesis provides an overview of possible failure scenarios and analysis their impact on transactional applications.The purpose of this document is to provide the system developers and administrators with information, which is essential for defining standard procedures and mechanism for failure handling.
