摘要： In distributed multinode data processing systems, mechanisms are employed to insure that the nodes are continually informed about the liveness of the other nodes within node groups in the network and across networks. The method of the present invention employs the concept of node stability which it uses to provide indications of membership in a previous stable group as part of messages transmitted in a protocol for forming, maintaining and dissolving node groupings in such a way as to assure that all of the nodes in the group have a consistent indication of liveness status for all of the nodes within any given group of nodes.

摘要： In distributed multinode data processing systems, mechanisms are employed to insure that the nodes are properly informed about the liveness of the other nodes in node groups in the network. In particular, the present invention employs group membership indicia as part of a mechanism for detecting that a node and/or its adapter have failed and have been recently restarted. Having detected this situation, group membership inconsistencies which it can engender are avoided.

摘要： A topology propagation facility is provided for maintaining a common network topology database at different nodes in a distributed computing environment. The facility generates no message traffic when the distributed computing environment is in steady state. This is accomplished by discontinuing sending of group connectivity messages during a time period of no topology change within the distributed environment. Sending of group connectivity messages is reinitiated from at least one group leader upon identification by the group leader of at least one topology change within the distributed computing environment. Group connectivity messages are forwarded from one group of nodes on a first network to another group of nodes on a second network using a node common to both groups of nodes. The networks of the distributed computing environment can comprise heterogenous networks such that the topology propagation facility presented facilitates interoperability of the networks.

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： A method for managing node-specific quorum roles in a cluster of nodes. The method comprises assigning a configuration change of node role attributes to a node in the cluster, with each attribute being represented by a bit of a binary value. The binary value corresponding to the specified node role attributes is converted to an integer value and the integer value is stored in a node record associated with the node. The node record is accessed to isolate each bit of the integer value associated with the node and the node role attributes assigned to the node are identified from each of the isolated bits of the integer value associated with the node. A determination of whether the configuration change can be safely supported by a configuration quorum of nodes required to represent the cluster's configuration accurately is made based on the identified node role attributes. An additional determination of whether a required operational quorum of nodes permits access to critical and shared resources is made based on the identified node role attributes. Endorsement for the configuration change is sought from subsystems that may be affected by the configuration change. The identified node role attributes are propagated to other nodes within the cluster.

摘要： A method is provided for establishing clusters in a distributed data processing environment having a plurality of nodes. The frequency of messages sent for the purpose of cluster formation is selected based on ranking of the nodes. Higher ranking nodes transmit such messages more frequently than lower ranking nodes. Lower ranked nodes thus are provided with an opportunity to join a cluster without first having to transmit their own messages to effectuate the joining.

摘要： A system to improve communication security in cluster machine processing may include interconnected computers that can jointly process data. The system may also include a shared secret key used by each of the interconnected computers to encrypt, decrypt, and/or authenticate data being sent, or received, from one of the interconnected computers to another of the interconnected computers. The system may further include a new shared secret key used by each of the interconnected computers to encrypt, decrypt, and/or authenticate data being sent, or received, from one of the interconnected computers to another of the interconnected computers. In addition, the new shared secret key may coexist with the shared secret key without adversely affecting the joint processing of data performed by the plurality of interconnected computers.

摘要： Liveness determination in a multinode data processing system is enhanced through the use of a shared nonvolatile memory, typically a disk, which is utilized in conjunction with defined transmission protocols to provide an independent communication path usable for both the transmission of node liveness information and for other, more general, data transfer purposes. This path is considered as having the same degree of importance as other network paths and liveness indications from the shared memory path are likewise considered at the same time as liveness indications from another path or paths.

摘要： Various components are provided to manage a clustered environment. These components include a System Registry that provides a global data storage; a Configuration manager that stores data locally on nodes of the clustered environment and globally within the System Registry; a Liveness component to provide status of communications paths of the cluster; a Group Services component that provides services to one or more other components of the clustered environment; and a Resource Management component that communicates with one or more resource controllers of the clustered environment. Each of the components of the clustered environment has one or more data and/or functional dependencies on one or more other components of the environment. However, relationships between the components are created such that the data and functional dependencies form an acyclic graph (i.e., a cycle of dependency relationships is avoided).
