Dealing with failures Sample Clauses

Dealing with failures. In the description of the algorithm we assumed no failures. Let us now study what happens if failures occur. According to our objectives, transactions should commit, even if some of the participants abort, and most importantly, sites should not become blocked. We consider three possible types of failure: site crash, message loss, and network partition.

Dealing with failures. In the description of the reconciliation algorithm, we assumed no failures. Let us now study what happens if failures occur. We have already noticed the algorithm is symmetric, except for the rst part in which one of the sites behaves as the starter of the reconciliation process. This symmetry is also re ected in the behavior of sites upon failures. If site x locally aborts a reconciliation on object o with site y, tuple (o; y) will not be deleted from Rec Infox. This ensures that the information regarding the need

Dealing with failures. In the description of the reconciliation algorithm, we assumed no failures. Let us now study what happens We now prove that the reconciliation algorithm is cor- rect. Correctness means that the value of an object o at commit of reconciliation re ects the timestamp- ordered execution of all the actions executed on o at the reconciling sites, and that Invariant 1 still holds. Theorem 2 If site x commits a reconciliation on ob- ject o with site y, the value of o at site x after rec- onciliation re ects the timestamp-ordered execution of all the distinct actions executed at x and y before rec- onciliation. q q y Proof First, we prove that all actions executed at site y and not executed at site x are communicated if failures occur. We have already noticed the algo- to x from y upon reconciliation, i.e., ao 2 H ^ ao 62 q q x rithm is symmetric, except for the rst part in which H ) ao o x
