Abstract: A system and method for securely transferring computer-readable objects across a remote boundary is provided. The method decomposes any type of object into a hierarchy of sub-components based on a list of known object types. Each sub-component either corresponds to a known object type or an unknown object type. The unknown object types may be decomposed further into known object types at another level in the hierarchy. The known objects in the hierarchy are serialized into a package that is transmitted to a remote entity. The remote entity reconstructs the hierarchy. For any of the known object types, the remote entity instantiates an object of the known object type and populates the object with information transmitted in the package. The decomposition may be limited by specifying a level for the hierarchy, specifying a number that limits the known objects that are serialized, or specifying the properties within the object to serialize.

Abstract: One embodiment of the present invention provides a system that facilitates bulk lock-unbiasing for objects within an object-based computing system. The system maintains an epoch, which is a field containing a timestamp, for a biasable object class and each instance of the biasable object class. If the epoch for the biasable object class matches the epoch for a specific instance of the biasable object class, the system knows that any bias for that specific instance is currently valid. When the system receives a signal to perform a bulk lock-unbiasing operation for instances of the biasable object class, it responds by stopping all threads in the object-based computing system at a safe point. Then, the system performs a bulk lock-unbiasing operation for unlocked instances of the biasable object class by incrementing the epoch for the biasable object class and by incrementing corresponding epochs for locked instances of the biasable object class.

Abstract: A method and computer program product for providing Global Attribute Uniqueness (GAU) using an Ordered Message Service (OMS) is presented. A database operation is received from a client. A determination is made regarding whether the operation changes a value to a current value and when the operation would change a value to a current value then operation is ended. When the operation would not change a value to a current value the operation is decomposed into ADD messages and DELETE messages. The ADD messages are sent to a GAU manager and GAU state is checked and updated. The updates are committed to GAU state and the Directory Server (DS) is updated. Operation is then returned to the client. DELETE messages are sent to the GAU manager and GAU state is updated. The updates are then committed.

Abstract: A remote procedure call channel for interprocess communication in a managed code environment ensures thread-affinity on both sides of an interprocess communication. Using the channel, calls from a first process to a second process are guaranteed to run on a same thread in a target process. Furthermore, calls from the second process back to the first process will also always execute on the same thread. An interprocess communication manager that allows thread affinity and reentrancy is able to correctly keep track of the logical thread of execution so calls are not blocked in unmanaged hosts. Furthermore, both unmanaged and managed hosts are able to make use of transparent remote call functionality provided by an interprocess communication manager for the managed code environment.

Abstract: A system and method provide for synchronous operation of linked command objects in a general purpose software application. The software application provides a user with a variety of operations that manipulate available data objects. The software application manages the data objects in a number of contexts. Each context manages the existence and execution of a number of command objects. Each command object operates on one or more data objects in its context. To support synchronous operations that affect the state of data objects in more than one context, command objects are linked to each other. When one command object is executed, the context of the command object identifies a command object linked to the executed command object and initiates the execution of the linked command object via the context that manages that command object. This synchronization allows for synchronous undo and redone operations. The delete states of the command objects are also synchronized.

Abstract: A computer-implemented method of configuring a computing system may include receiving first user-actuated input selecting an existing service provider that processes data objects having a first data object type. The existing service provider may include at least a first class and a second class. Second user-actuated input may be received that identifies the first class and provides a replacement class to use in creating a new service provider to process data objects having a second data object type. An association may be stored in a service provider system between the second data object type, the existing service provider, the first class and the replacement class. During runtime, the service provider system may create the new service provider to process data objects having the second data object type by inheriting the second class from the existing service provider and incorporating the replacement class in place of the first class.

Abstract: A method and apparatus is provided for providing and integrating high-performance message queues. “Contexts” are provided that allow independent worlds to be created and execute in parallel. A context is created with one or more threads. Each object is created with context affinity, allowing any thread inside the context to modify the object or process pending messages. Threads in a different context are unable to modify the object or process pending messages for that context. To help achieve scalability and context affinity, both global and thread-local data is often moved into the context. Remaining global data has independent locks, providing synchronized access for multiple contexts. Each context has multiple message queues to create a priority queue. There are default queues for sent messages and posted messages, carry-overs from legacy window managers, with the ability to add new queues on demand. A queue bridge is also provided for actually processing the messages.

The associative relationships may be advantageously established without modification of the code comprising the contained object.

Abstract: A broker of the present invention enables distributed applications to communicate with a server in distributed computing environment. The broker receives from a client a request to execute a transaction. The broker receives input parameters including input data. The broker uses a routing service to locate the server. The broker then establishes a communications connection to the server and forwards the input data. The transaction is executed and the broker receives a response from the server. The broker forwards the response to the client. The broker can segment the input data before forwarding the input data to the server. If the response is in multiple segments, the broker can combine the multiple segments into one string before forwarding the response to the client. Further, the broker may receive requests from multiple clients via multiple communications connections. The broker then consolidates the multiple communications connections and establishes one communications connection to the server.

Abstract: In mobile computing and context awareness in mobile ad-hoc networks, node connectivity is unpredictably time-varying. A middleware entity solves the problem of automatically executing a user-defined set of actions, collected in a user profile, upon detection of events such as an attachment of a mobile terminal to the ad-hoc network, changes of the underlying network topology, the moving of mobile terminals into the physical proximity of further mobile terminals, the presence of services and/or of users within the network, and a detachment of a mobile terminal from the ad-hoc network. Thereby, the actions are invocations of services hosted on the mobile terminal or other mobile terminals interconnected via the ad-hoc network. The aforementioned profiles are stored on mobile terminals (e.g. PDAs, mobile phones, etc.) or on fixed or mobile customer-edge devices such as television sets, home gateways, etc. Also envisioned is the deployment of a distributed database holding the profiles.

Another interface accepts a handle that refers to an identifying data segment, and determines if the object corresponding to the identifying data segment has been changed in the first object store since the last synchronization.

Abstract: A method, system and computer program product for configuring an application instance. A first path by which an application instance is configured to access a version of a resource is determined. Additionally, a determination is made as to whether a configuration associated with the application instance exists in a shared resource area. If the configuration does not exist, a base version of the resource is modified to generate a customized version. A second path is determined, and the customized version is stored thereat. If the configuration exists, the second path is determined such that the resource included in the configuration can be accessed thereat. A symbolic link having an origin of the first path and a destination of the second path is created. Using the present invention, multiple application instances can efficiently share customized versions of resources.
