Inventory updating of an internet protocol (IP) alias within a highly available computing cluster

摘要

A clustered computing data processing system can be configured for inventory management in a highly available cluster. The system can include a cluster of computers managed by a cluster agent and providing high availability for a hosted application in the cluster. The system also can include a systems management tool executing in memory of a host computer system and coupled to the cluster agent and maintaining an inventory of data pertaining to the computers in the cluster. The system yet further can include an Internet protocol (IP) alias discover module coupled to the tool. The module can include program code executing in the memory of the host computer system so as to receive notification from the cluster agent of a change to addressing data for the computers in the cluster and, responsive to the notification, to update the inventory to reflect the change to the addressing data.

1. A clustered computing data processing system configured for inventory management in a highly available cluster, the system comprising:
a cluster of computers managed by a cluster agent and providing high availability for a hosted application in the cluster; a systems management tool executing in memory of a host computer system and coupled to the cluster agent and maintaining an inventory of addressing data pertaining to the computers in the cluster, wherein the addressing data for each computer in the cluster includes both a boot Internet Protocol (IP) address referring to a network interface of the computer at which the computer is accessed and also an alias IP address referring to a service IP address at which a service executing within the computer is accessed; and, an Internet protocol (IP) alias discover module coupled to the tool, the module comprising program code executing in the memory of the host computer system so as to receive notification from the cluster agent of a change to alias IP address data for the computers in the cluster by detecting a change in status of a flag by the cluster the flag status being based upon a hash value of the addressing data maintained by the system management tool and, responsive to the notification, to update the inventory to reflect the change.
