    摘要: A system and techniques are described for managing key-value pairs using an architecture that does not restrict its users to any specific platform or storage subsystem. According to one aspect of the invention, the repository is portable in that the architecture need not change based on the environment and platform in which the repository is used. Rather, the portion of the architecture that is platform-specific is limited to plug-ins at a storage abstraction layer of the repository. The plug-ins expose the same storage abstraction interface to the other layers of the repository, but are implemented to interact with different platforms and storage subsystems. Consequently, in response to being ported from one platform to another, the repository may simply change the plug-in to invoke for persistent storage operations.

    摘要: A system and techniques are described for creating member private data in a global namespace. According to one aspect, first data that is associated with a key is stored in a repository shared by multiple members. After the first data has been stored, second data that is associated with the key is stored without overwriting the first data. Mapping data is stored. The mapping data maps the key, relative to a first member, to a first data structure that stores the first data. The mapping data also maps the key, relative to a second member, to a second data structure that stores the second data. Based on the mapping data, the first member is allowed to access the first data and not the said second data. Based on the mapping data, the second member is allowed to access the second data and not the first data. The first data and the second data may include key values and subtrees of child keys.

    摘要: A method and mechanism for utilizing a meta-language to define and analyze traces is disclosed. A set of trace format grammars can be defined for traces. Each trace format grammar is preferably compliant with guidelines for a meta-language grammar. The trace format grammars can be examined to form a suitable analyzing mechanism, such as a parser, to analyze the traces.

    摘要: A system and techniques are described for formatting a persistent storage device to store hierarchical data. According to one aspect of the invention, data structures are established, at a base level of the persistent storage device, for storing a hierarchy of key-value pairs. A first structure, which corresponds to a root node of the hierarchy, is established. A second structure, which corresponds to a key-value pair, is established. The second structure stores the value of the key-value pair. Links, which lead from the first structure to the second structure through one or more intermediate structures, are established based on a position, within the hierarchy, of the key.

    摘要: Less-restrictive techniques are provided for ensuring that replicated-data systems will never provide out-of-date version of data items. A replicated-data system maintains a version number, a membership group identifier, and a membership count, with each replica of a data item. These values are maintained in such a way as to allow the replicated-data system to reliably satisfy some read requests even though half, or less than half, of the replicas of the data item are available.

    摘要: Allowing for resource attributes that may change dynamically while the resource is in use, provides for dynamic changes to the manner in which such resources are managed. Management of dynamic resource attributes by clusterware involves new entry points to clusterware agent modules, through which resource-specific user-specified instructions for discovering new values for resource attributes, and for performing a user-specified action in response to the new attribute values, are invoked. A clusterware policy manager may know ahead of time that a particular resource has dynamic attributes or may be notified when a resource's dynamic attribute has changed and, periodically or in response to the notification, request that the agent invoke the particular resource-specific instructions for discovering new values for attributes for the particular resource and/or for performing a user-specified action in response to the new attribute values. During the majority of this process, the resource remains available.

    摘要: There are disclosed methods and a packet receiver for testing a network. A packet may be received from the network at a port unit. The port unit may ignore the received packet if the received packet does not contain a valid test signature. When the received packet contains a valid test signature, the port unit may determine if the port unit is an expected destination for the received packet. When the port unit is not an expected destination for the received packet, a misdirected packet counter may be incremented. When the port unit is an expected destination for the received packet, test data may be extracted from the received packet.
