摘要:
A solution for managing a computer infrastructure is provided. In particular, the solution can generate a set of tentative recovery segments for the computer infrastructure based on a related resource graph and a set of partition rules. The related resource graph can be generated based on a managed resource graph, which includes resource type information for each node in the managed resource graph. The set of tentative recovery segments can be used to manage the computer infrastructure and/or a set of recovery segments, which includes recovery characteristic(s) for each segment can be generated based on the set of tentative recovery segments and a set of recovery segment templates. In any event, the invention provides a solution that fully and/or partially automates the identification of recovery segments within a computer infrastructure, thereby enabling a more effective management of the computer infrastructure.
摘要:
An autonomic computing system and method determine policy definitions (404) and a set of available actions (410); monitor resources distributed within the system; determine if the system is at a desired end state; and modify resource states by sending instructions for the resources to perform available actions. The policy definitions (404) specify: start order between resources, prioritization between resources, conditional activation of policies, desired end state of resources, and location limitation of resources. The system and method receive status information from available resources, and monitor and modify the system until it reaches the desired end state. The policy definitions (404) can be determined by specifying a user-defined system end state and resource relationships. The policy definitions (404) can further harvest implicit relationships between resources, via self-discovery, and underlying relationships among resources.

摘要:
A network having a plurality of nodes is reconfigured to reflect a change in topology of the network. In particular, upon receiving a reconfiguration request, each node enters a quiescent state for a predetermined period of time sufficient to allow at least one other node to also enter a quiescent state. Then, upon termination of the quiescent state, the node is reconfigured to reflect the change in the topology of the network without having to check with any other nodes of the network. In other embodiments, the predetermined period of time is sufficient to allow currently executing protocols to complete execution as well as to allow the transmission of reconfiguration requests for propagating reconfiguration in the network.

摘要:
An autonomic computing system and method determine that a desired end state cannot be reached, determine that an acceptable sub-state can be reached using at least one of priority ratings, conditional relationship specifications, and alternative relationship specifications, and place the computing system in an acceptable sub-state. The priority ratings can contain an attribute assigned to a policy definition that determines a sequence for applying the policy definition. The attribute can be “mandatory”, a numerical value, or “not required”. The conditional relationship specifications have policy definitions that are applied when the state of a specified resource meets a predetermined requirement. An alternative relationship specification has policy definitions and/or conditional relationship specifications that are applied when the state of a specified resource does not meet a predetermined requirement.
摘要:
The determination of node and/or adapter liveness in a distributed network data processing system is carried out via one messaging protocol that can be assisted by a second messaging protocol which is significantly less susceptible to delay, especially memory blocking delays encountered by daemons running on other nodes. The switching of protocols is accompanied by controlled grace periods for needed responses. This messaging protocol flexibility is also adapted for use as a mechanism for controlling the deliberate activities of node addition (birth) and node deletion (death).

摘要:
A system and method for monitoring liveliness includes a management device which has an application layer where applications are executed. A connection monitor is located other than on the application layer, and the connection monitor is configured to receive requests from clients and deliver the requests to components on the application layer. The components include a generic application monitor which responds to liveliness monitor requests from the clients for all applications monitored, and one or more applications which response to requests to that application.
