Abstract:
A histogram, or resource status history table, for multiple resources is created and maintained. A transaction or resource manager arranges and/or reorders various resources into a sequence based on the histogram such that read-only resources are prepared first and a sole non-read-only resource need not be prepared, but only committed. The transaction manager heuristically determines the order that resources are driven to achieve last-agent optimization. The histogram is kept related to context, based on runtime and applications context to ensure that usage patterns by context are optimized without the need for the installation to know any usage patterns.
