Abstract
A method and apparatus for debugging a software program is provided. In one example, a method includes preserving consecutive snapshots of a group of shared memory structures that contain data and control information of the software, such as a database system. A first snapshot may be taken immediately prior to the occurrence of an error, and a second snapshot taken after the occurrence of the error. The consecutive snapshots are compared to each other to determine what memory structures and data are affected by the error.
