Mechanisms for providing requested date items in a request-driven enumeration session while retaining to control over how much inter-message context information is retained by the data provider. Upon receiving a request for the data items, the data provider identifies a portion of the data items to be provided in the first response along with context information that reflects that the first portion of information has been provided. The data provider then makes a determination of how much of the context is to be provided to the data receiver system, and then provides that appropriate context information to the data receiver. Furthermore, the data provider provides a response that includes the first portion of the data items. The data receiver includes this first provided context information in the second request for the next portion of the data items, allowing continuity in the data transfer session.

To maintain and manage a computer network, a system administrator may monitor a large number and variety of components, each component comprising a variety of resources. The instrumentation of a resource may be monitored and/or manipulated by receiving a Simple Object Accessing Protocol (SOAP) message comprising an operation identifier for accessing instrumentation information and a resource identifier associated with a computer system resource. The management system may resolve the resource identifier into an address for a local handler associated with the resource, and may send a local request to the local handler at the resolved address.

Example embodiments provide for “heartbeat” subscriptions which can be thought of as pseudo-events that can occur periodically for any subscription. Notification of a heartbeat event can be sent in lieu of, or in addition to, regular events to inform the subscriber application of such things like the subscription is still active and/or that connectivity exists between the subscriber application and the publishing service application. Alternatively, if the heartbeat notification does not arrive at the subscriber application, then the client knows that the connectivity is bad or that the subscription has expired and it may take corrective action (e.g., attempt to re-subscribe to the appropriate subscription). Note that similar embodiments also apply to pull requests received by the publishing service from the subscriber.

A system that uses a Uniform Resource Identifier (URI) to uniquely identify a class of resources. The schema uses a URI with a placeholder substituted for the resource name, effectively creating a URI template. Processing of the URI template facilitates retrieval of resource class information. If specificity is required, the URI template can be converted to a specific URI by replacing the placeholder with the name of a given resource or instance to get information about that particular instance. URI templates allow probes to be identified and the probe characteristics to be understood without actually retrieving the probe for a particular instance.

Systems and methods for reporting the occurrence of events in a computer system to event subscriber software are disclosed. Events arc detected within a computer system or computer system environment by event detection components. An Event provider receives notification of the occurrence of each event. Instead of the event provider then forwarding each of the events to a single, centralized location for filtering, embodiments of the present invention perform the filtering of events at the location of the event provider. This is accomplished by custom forward marshaling a proxy to each event provider. Also marshaled is at least one event-filtering definition that specifics which events should be reported by that event provider to the subscriber software. The event-filtering definitions are written in a structured query language, which can be used to precisely select which events are to be reported. In this way, instead of reporting each event received by it, an event provider, by virtue of the proxy procedure, will only report those events that have been requested by an event subscriber. Non requested events are discarded, thereby reducing the use of processing resources that would otherwise be used if all events were sent to a single, centralized filter.

Embodiments provide for query expressions to be utilized within a SOAP message for content fragment transfer and document update purposes. In one embodiment an inverse query path within a SOAP message in used conjunction with an operation for modifying a targeted XML document. Mechanisms are also provided that allow transferring of fragments of content for an XML document within a SOAP message. Such fragments are usually by themselves not schematically valid. Nevertheless, by encapsulating the fragmented content within a special wrapper construct, the subset of content suddenly become legal XML; thus passing most any validation test imposed by SOAP processors. More specifically, the wrapper construct is itself schematized as requiring that SOAP processors skip or otherwise suppress processing any child elements within the contained wrapper.

Subscription-based notification using event channels that each correspond to a particular scope. Each channel manages notifications through the use of a a schema definition. The event subscriptions identify the position and attributes that any desired event notification would take in the schema definition. The channel then receives event notifications in the form of XML fragments. The channel then determines the position that the XML fragment would take as defined by the schema definition. The channel determines whether the position and attributes of the event notification matches the position and attributes of the event subscription. If a match is found, then the event notification is copied and forwarded to the recipient designated in the corresponding subscription.

In accordance with certain aspects of the model-based policy application, each of a plurality of policies is associated with appropriate parts of a model of a heterogeneous system. A deployment agent is invoked to apply each of the plurality of policies to components associated with the parts of the model. An identification of a change to one of the plurality of policies is received, and the deployment agent is also invoked to apply the changed policy to selected ones of the components associated with the parts of the model.

The present invention extends to methods, systems, and computer program products for modeling XML from binary data. A rendering module receives a request for an XML document and retrieves binary data corresponding to the requested XML document. The binary data includes at least one data value and a template reference referencing a reusable template. The rendering module accesses the reusable template referenced by the template reference. The reusable template includes fixed portions of XML and at least one replaceable token representing that at least value is to be substituted into the reusable template to replace at least one replaceable token. At least one replaceable token in the template is replaced with a data value from the binary data. The fixed portions of the XML along with the data value from the binary data are rendered as the requested XML document.

A common information model (CIM) enables management application programs to receive uniformly rendered results regardless of the source of the information. A CIM object manager isolates the applications from internal components which retrieve the information from various sources and through various other components, and provides refinements to that model that improve the exchange of information. In addition to providing uniform rendering of management information to a client applications, the CIM object manager dynamically adapts to complement the capabilities of the information providers, whereby the information providers may do so in a highly flexible manner. The CIMOM also decomposes a client query to determine the appropriate source or sources of information necessary to resolve that query, and further handles client queries having inherited object classes to render appropriate results in a uniform manner.
