摘要： A system and method for providing message-based leasing of resources in a distributed computing environment. Services may issue leases to clients and provide operations on those leases. The lease functionality of a service may be defined in an XML message schema. Gates may be used to perform lease operations. Leases may be granted for a period that may be negotiated. Leasing messages for performing leasing operations may be defined. The leasing messages may include messages to renew a lease and to cancel a lease. Services may specify an address where leasing messages may be sent. A lease renewal mechanism may be provided in which a gate may receive lease renewal messages and automatically respond to them. A mechanism to detect stale advertisements in a space may be provided. When a service publishes its advertisement in a space, the service obtains a lease on the publishing of its advertisement. Each advertisement may include a time by which the service may renew the advertisement. When the lease is not renewed, the space service marks the service advertisement as stale. Services renew advertisements by sending a renewal message to the space. Stale service advertisements may be deleted after a period. A space service may allow clients to lease service advertisements in the space to thus grant clients access to the services. Messages are described for accessing the leasing services provided by the space services.

摘要： A method and system for performing generational garbage collection on a virtual heap in a virtual machine is provided. The garbage collection method is suited for use with small consumer and appliance devices that have a small amount of memory and may be using flash devices as persistent storage. The garbage collection method may provide good performance where only a portion of the virtual heap may be cached in the physical heap. The virtual heap may use a single address space for both objects in the store and the in-memory heap. In one embodiment, a single garbage collector is run on the virtual heap address space. The garbage collection method may remove non-referenced objects from the virtual heap. The garbage collection method may also include a compaction phase to reduce or eliminate fragmentation, and to improve locality of objects within the virtual heap. In one embodiment, the garbage collector for the virtual heap may be implemented as a generational garbage collector using working sets in the virtual heap, where each generation is confined to a working set of the heap. The generational garbage collector may allow the flushing of changes after each garbage collection cycle for each working set region. Heap regions with different flushing policies may be used. An object nursery region without flushing where objects are initially created may be used. When a garbage collection cycle is run, objects truly referenced in the object nursery may be copied back into heap regions to be flushed, while short-lived objects no longer referenced may be deleted without flushing.

摘要： A system and method for providing process persistence in a virtual machine are described. A virtual persistent heap may be provided. The virtual persistent heap may enable the checkpointing of the state of the computation of a virtual machine, including processes executing within the virtual machine, to a persistent storage such as a disk or flash device for future resumption of the computation from the checkpoint. The Virtual Persistent Heap also may enable the migration of the virtual machine computation states, and thus the migration of executing processes, from one machine to another. The saved state of the virtual machine heap may also provide the ability to restart the virtual machine after a system crash or shutdown to the last saved persistent state, and to thus restart a process that was running within the virtual machine prior to the system crash or shutdown to a checkpointed state of the process stored in the virtual persistent heap. This persistent feature is important for small consumer and appliance devices, as these appliances may be shutdown and restarted often.

摘要： A method and system for serializing a transient object-oriented database into a persistent form. The persistent form is a grammatical form, an expression of an object-oriented database in a textual form according to a grammar. The grammatical form is human-readable and human-editable. The grammar is designed to be platform-independent and programming-language-independent and therefore descriptive of any hierarchical object-oriented database. An object-oriented database is expressed as a plurality of entries in a transient, hierarchical, object-oriented form. The tree of entries is navigated and each entry is written to the persistent form as text according to the grammar. The serialized form stores only the key state of the database, not a “snapshot” of memory. Therefore, the persistent, serialized form is smaller than the in-memory, transient form of the object-oriented database. The object-oriented database is an object-oriented configuration database which stores configuration parameters pertaining to the software and hardware of a computer system, such as application programs, device drivers, system services, and other components. The object-oriented database is platform-independent and is therefore configured to be hosted on several different operating systems and computing platforms.

摘要： A method and system for transforming an intermediate form into an object-oriented database. The intermediate form is derived from a grammatical form of an object-oriented database through the process of compilation. The grammatical form is an expression of an object-oriented database in a textual form according to a grammar. The intermediate form comprises an array of intelligent entry objects that encapsulate data with methods for manipulating that data. The intermediate form comprises entries as in the object-oriented database but lacks the infrastructure of the database. The intermediate form can be used to populate the object-oriented database with entries. Population takes place through a public API for accessing the object-oriented database; in other words, through an interface which declares methods for navigating the database and adding entries to the database. The object-oriented database is an object-oriented configuration database which stores configuration parameters pertaining to the software and hardware of a computer system, such as application programs, device drivers, system services, and other components. The object-oriented database is platform-independent and is therefore configured to be hosted on several different operating systems and computing platforms.

摘要： A cluster implements a virtual disk system that provides each node of the cluster access to each storage device of the cluster. The virtual disk system provides high availability such that a storage device may be accessed and data access requests are reliably completed even in the presence of a failure. To ensure consistent mapping and file permission data among the nodes, data are stored in a highly available cluster database. Because the cluster database provides consistent data to the nodes even in the presence of a failure, each node will have consistent mapping and file permission data. A cluster transport interface is provided that establishes links between the nodes and manages the links. Messages received by the cluster transports interface are conveyed to the destination node via one or more links. The configuration of a cluster may be modified during operation. Prior to modifying the configuration, a reconfiguration procedure suspends data access requests and waits for pending data access requests to complete. The reconfiguration is performed and the mapping is modified to reflect the new configuration. The node then updates the internal representation of the mapping and resumes issuing data access requests.

摘要： Methods, apparatus, and software for endianness checking for platform-independent device drivers is described. According to one embodiment, the method of the invention includes generating a memory allocation request from a platform-independent device driver. The driver instantiates a memory constraints object that is configured to report the endianness of the driver. The request is received by a bus manger that is configured to process memory allocation requests from the device driver and has an endianness independent of the device driver. If the endianness of the bus manager and device driver is inconsistent, then the memory constraints object is transformed to be consistent with the bus manager's endianness.

摘要： Methods and apparatus are disclosed for providing a data framework and associated client/server protocol for storing and exchanging data among computers in a network. A data schema having an n-way tree-type structure with a root node layer, intermediate node layers, and a data layer for storing configuration data is described. The intermediate node layers contain a multitude of nodes containing categorical information relating to components and various aspects of the computer network. Following a tree structure, each intermediate node and root node has branches emanating to nodes below it. These subordinate nodes are referred to as children nodes. The data node layer is at the bottom of the tree and contains actual specific configuration data relating to components and other aspects of the computer network, such as information regarding users registered to use the network. Certain portions of the intermediate nodes and data nodes make up persistent dataspaces in which the actual specific configuration data in the data nodes is modified on either a client or a server computer, and is stored on the server computer. This allows the associated specific information to be nonvolatile and accessible by a multiplicity of client computers. The client/server protocol allows configuration data to be transferred between a client and server and for the maintenance of the connection between the client and the server. Configuration data and user profiles are stored on a server computer thereby minimizing the amount of memory needed by the client computer, which can be a device with low memory capabilities such as network computers, PDAs, or smart cards. The protocol also includes a method of coalescing configuration data before sending it to a client computer thereby reducing the memory requirements of the client computer.
