Abstract
The 2PC protocol together with strict 2PL can be considered
as a de-facto standard for distributed transaction
processing. However, 2PC is often unacceptable from a
performance and execution autonomy point of view.
Multi-level transaction management offers an alternative
solution that allows early commits of subtransactions and
thus improves performance and execution autonomy. While the
theory of this approach is well established, a practical
evaluation in a multi-database environment is still lacking.
This paper describes a prototype implementation and initial
measurements that compare transaction processing with 2PC
versus distributed multi-level transaction
management. Although we used SQL in our examples, the
concepts presented here are applicable to any notion of
distributed object management system.
