Communication graph tracking of multi-system operations in heterogeneous database systems

Abstract:

Techniques a provided for communication graph tracking in multi system operation in heterogeneous database systems, including retrieving two or more database commit logs from two or more corresponding heterogeneous databases. For each of the commit logs, a subset of information is extracted, including a correlation identifier, and event stream entries are produced based on that information and are stored. The event stream entries are then retrieved and event database entries are created based on the event stream entries. A request for a communication graph related to a particular correlation identifier is received and the event database is searched for matching entries. Those entries are used to generate a displayable communication graph for the particular correlation identifier, which is then provided in response to the request.
