Oracle SOA Suite 11g has some great features to recover faulted instances automatically. When a BPEL process flow errors out, it is retried with all its invocations.

All of these "functions" can be supported by services, but often also by precisely defined process chains. However, complex business processes can rarely be automated "in one piece," as...
