ABSTRACT:
TECHNICAL FIELD
This invention relates, in general, to a distributed computing environment, and in particular, to managing one or more clusters of nodes of a distributed computing environment.
BACKGROUND ART
Distributed systems are highly-available, scalable systems that are utilized in various situations, including those situations that require a high-throughput of work or continuous or nearly continuous availability of the system.
A distributed system that has the capability of sharing resources is referred to as a cluster. A cluster includes operating system instances, which share resources and collaborate with each other to perform system tasks. While various cluster systems exist today (such as the RS/6000 SP system offered by International Business Machines Corporation), further enhancements to the existing cluster systems are still desired. For example, enhancements are desired to facilitate the administration of cluster systems.
SUMMARY OF THE INVENTION
The shortcomings of the prior art are overcome and additional advantages are provided through the provision of a method of defining nodes to a cluster of a computing environment. The method includes, for instance, determining whether a local definition of a node to be defined to the cluster exists; determining whether a global definition of the node exists; comparing the local definition to the global definition, when the local definition and the global definition exist; deleting the local definition and the global definition, if the comparing indicates an inequality or if one of the local definition and the global definition exists without the other; and defining the node to the cluster.
System and computer program products corresponding to the above-summarized methods are also described and claimed herein.
Additional features and advantages are realized through the techniques of the present invention. Other embodiments and aspects of the invention are described in detail herein and are considered a part of the claimed invention.
