Abstract: Methods and apparatus involve continuous management of workloads, including regular monitoring, profiling, tuning and fault analysis by way of instrumentation in the workloads themselves. Broadly, features contemplate collecting current state information from remote or local workloads and correlating it to predefined operational characteristics to see if such defines an acceptable operating state. If so, operation continues. If not, remediation action occurs. In a virtual environment with workloads performing under the scheduling control of a hypervisor, state information may also come from a hypervisor as well as any guest user and kernel spaces of an attendant operating system. Executable instructions in the form of probes gather this information from items of the stack available for control and deliver it to the management system. Other features contemplate supporting/auditing third party cloud computing services, validating service level agreements, and consulting independent software vendors.

Abstract: A LOCATE search dynamically locates resources (e.g., logical units (LUs) and transaction program and files associated with LUs) in a computer network so that a session can be established between the origin and the destination of the search.In a network which includes end nodes associated with server nodes, a resource contained in any node is located by a requesting node. The requesting node initiates a search of the resources residing within itself. If the resource does not reside in the requesting node, the server node searches the resources known to the server node that reside anywhere in the nework. If the resource is not known by the server node, it searchers all resources that reside in its associated end nodes. If the resource does not reside in the associated end nodes, either a request is sent to a central directory if one exists or a search of all resources in the network is made.

Abstract: The disclosure provides improvements in effecting the routing function in a communication network operating under a distributed control protocol. Selected nodes (control nodes) have extended memory and computing capabilities and each maintains a topology data base, other nodes (ordinary nodes) have more limited memory and computing capabilities and maintain information respecting solely local topology. The method of the invention provides for maintaining the topology data bases in the control nodes current in the face of changes in the network, provides for the selection of a particular control node from which a particular ordinary node will obtain necessary routing information and establishes and maintains communication between the ordinary node and the selected control node. Control nodes identify adjacent control nodes, and upon determining changes in network status, such network status changes are communicated to the adjacent control nodes.
