International Business Machines Corporation - Armonk NY

International Classification:

G06F009/46

US Classification:

719313, 719311, 719315

Abstract:

A method for allowing an enterprise application server to integrate and make use of any messaging product or products that support a standard messaging service interfaces. In a first phase of the method, an administrator creates and installs a new messaging provider on an application server, creates new messaging resource objects such as connection factories and destinations, and then binds these into the original namespace of the default messaging provider. An application which references the new messaging provider is then deployed onto the application server. Then, when the application program is executing, it may perform a lookup for the new messaging service, which the application server performs through the default context factory to obtain a new messaging object, which is then handed to the requesting application for use as needed. This method of indirection allows the application server to integrated and use any messaging service, not just the default messaging server originally integrated by the application server vendor.

Abstract:

A security policy process which provides role-based permissions for hierarchically organized system resources such as domains, clusters, application servers, and resources, as well as topic structures for messaging services. Groups of permissions are assigned to roles, and each user is assigned a role and a level of access within the hierarchy of system resources or topics. Forward or reverse inheritance is applied to each user level-role assignment such that each user is allowed all permissions for ancestors to the assigned level or descendants to the assigned level. This allows simplified security policy definition and maintenance of user permissions as each user's permission list must only be configured and managed at one hierarchical level with one role.

International Classification:

US Classification:

709227, 709203

Abstract:

A system and method for distributing management events to external process is presented. A notification listener registers with a client notification service that resides locally with the notification listener. The registration includes one or more notification types in which the notification listener wishes to be notified. The client notification service configures a remote proxy located on a server to provide notification events to the client notification service that have one of the notification types. The remote proxy receives notification events from a server notification service, and provides the notification events to the client notification service. In turn, the client notification service provides the notification events to the notification listener. The remote proxy may be configured for push processing or pull processing. When the remote proxy is configured for push processing, the remote proxy sends notification events to the client notification service without receiving a request from the client notification service.

US Classification:

719313, 709238

Abstract:

The present invention routes object requests in a distributed system using address information identified in object headers that accompany the request. Specifically, when an object is created under the present invention, address information is inserted into a corresponding object header. When a request related to the object is later issued, the object header accompanies the request. The address information is used to ensure that the request is efficiently and accurately routed to a target process within a target node of a target cell.

International Classification:

US Classification:

707102

Abstract:

Methods, systems, and media are disclosed for managing a resource managed by a mbean server having an mbean. One embodiment includes receiving a request by the application, wherein the request constitutes an action a user seeks to perform on the resource, and adding a number of instance identifier fields to an mbean descriptor file associated with the mbean. Further, the embodiment includes populating the number of instance identifier fields with an equivalent number of properties from an objectname of the resource, thereby producing a populated mbean descriptor file that identifies the resource among resources. Further still, the embodiment includes reading the mbean descriptor file after the populating, and determining, based on the reading, whether the user has an authority to perform the request. If authority exists, then an mbean method performs the action on the resource, and filters the obtained results to coincide with the user's authority.

US Classification:

717120, 717174, 707103 R

Abstract:

A method is presented for managing applications using application-based names. A naming service registers an alias name; the alias name represents a first compound name that includes an application name that is associated with an application and a deployment name that is associated with a deployment attribute that characterizes a deployment of an instance of the application. The naming service is also able to generate an application-based name associated with an application; the application-based name represents a context within a naming system, and the application-based name is a second compound name that includes the alias name. Applications are managed within a data processing system using application-based names. The first compound name can be associated with a first topology-based name that represents a first context for organizing files that are related to the instance of the application.

International Classification:

US Classification:

702185, 340 31

Abstract:

Provided is a method for programming module load balancing and failover in a distributed computing environment. The Java Management extensions (JMX) specification is enhanced to support load balancing and provide a high-availability of JMX management beans (Mbeans). Also provided are enhancements to the programming model and infrastructure to support the enhanced programming model. Two exemplary approaches for load balancing and failover are provided, one based both upon clustered Mbeans and one based upon unclustered Mbeans. In the unclustered approach, client affinity is supported in that a request from a particular client can be routed to a particular Mbean. In the clustered approach, a specific Mbean can be invoked by providing a special parameter in the Mbean invocation or by adding a special property to the specific Mbean's ObjectName to indicate that during runtime automatic routing should not be employed.

Abstract:

A method, apparatus and computer instructions are disclosed for maintaining the compatibility of a multiple nodes in a distributed systems management environment with multiple configuration settings, by transforming the configuration data stored in the master repository (one possible realization is where XML documents contain the configuration data) from one version of the product to a previous version of the product. For multiple versions of the systems management environment, a transformation pipeline process (one possible realization of such a process may utilize XSLT) can be used by a “master” node to transform the configuration data multiple times for each version of the environment, until the configuration data has the format of the intended recipient “slave” node. Also, by performing the transformation process on the “master” side of the computing environment, “slave” nodes with older version configuration settings can continue to operate without having to upgrade their software applications in this regard.
