DELETING CONFIGURATION ITEMS IN A CONFIGURATION MANAGEMENT DATABASE

摘要

Embodiments of the present invention provide automated systems and methods for selectively finding and deleting dormant data (out of data, inactive data) in a configuration management database (CMDB), or in a database which has similar characteristics. The method includes using a directed graph where each node of the directed graph represents a configuration item, and traversing the directed graph in order to determine inactive or dormant data, and all of the objects which depend on that data. Configuration items are deleted only when all of the other configuration items from which it depends contain dormant data.

1. A method for operating a configuration management database (CMDB), the method comprising:
for a configuration item in a configuration management database (CMDB), responsive to updating the configuration item, determining, by one or more processors, a last update time associated with the updated configuration item; receiving, by one or more processors, an indication to delete a configuration item; responsive to receiving the indication to delete the configuration item, determining, by one or more processors, whether an age of the configuration item is greater than a threshold, wherein the threshold comprises a difference between a current time and the last update time; responsive to determining that the age of the configuration item is greater than the threshold, assigning, by one or more processors, the configuration item a deletion-candidate label; identifying, by one or more processors, a set of configuration items associated with a set of nodes of a directed graph, wherein the set of nodes of the directed graph are assigned the deletion-candidate label; and deleting, by one or more processors, the set of identified configuration items assigned the deletion-candidate label.
