Abstract: A mechanism for locating information about a target entity in disparate multilevel hierarchical knowledge repositories. Upon occurrence of an event associated with a target entity comprising an information technology solution, disparate multilevel hierarchical knowledge repositories are searched for metadata about the target entity. A determination is made from the metadata about the target entity whether the repositories comprise entities related to the target entity. If so, links in the metadata are used to search the repositories to locate the related entities. Upon locating a resolution to the event in the repositories, a link to the resolution is stored in the metadata. The repositories are also searched to determine owners of the target entity and related entities, and these owners are then notified of the event and the resolution to the event.

The apparatus further comprises an adaptive equalizer capable of equalizing the received data, connected to the data path, and a synchronous decorrelator connected to the data path, in communication with the adaptive equalizer, wherein the synchronous decorrelator evaluates an adapt enable output for each received data input to the adaptive equalizer to determine whether the adaptive equalizer can update settings of the line equalizer adaptive system.

Abstract: A computer implemented method, a tangible computer readable medium, and a data processing system intelligently propagate link status information received by a blade server to the various ports of an embedded multi-port switch. The link status of a switch port in an external switch module can be communicated to the operating systems of individual blade servers that are affected by that link status. When an external switch module is unplugged from a server blade chassis, the bus controller broadcasts a link down event, such as a link down interrupt, to the individual server blades where it is received by the embedded multi-port switch for those server blades. The embedded multi-port switch translates the link down interrupt into a hardware link down event, and forwards the hardware link down event to the other elements connected to the embedded multi-port switch.

Abstract: A method, apparatus, and computer usable code for managing confidential data. A request is received to access an application from a user, wherein the application includes logic to process the confidential data. One of a first interface or a second interface is selected based on an identification whether the user is permitted to see the confidential data to form a selected interface in response to receiving the request. A selected interface is presented to the user. The first interface presents the confidential information and second interface presents non-confidential information without presenting the confidential information. The second interface allows access to the logic in the application without accessing the confidential data.

Abstract: A computer implemented method, apparatus, and computer program product for performing an automated task in a role-based access control environment. A set of roles is assigned to a user to form assigned roles, wherein the role-based access control environment allows the user to assume a subset of the assigned roles at a given time. Responsive to receiving a request to execute an automated task, an identity of the user creating the automated task is identified. Responsive to determining that the user creating the automated task is not logged in, a set of session roles are identified based on the identity of the user. A session is created for the automated task. The automated task is performed in the session using the set of session roles.

Abstract: Delegating resource management to customers in a technology outsourcing environment includes providing the customer with a secured user interface (e.g., HTML pages) for selecting one or more parameters (e.g., User Ids, application name and version, etc.) associated with a resource management task (e.g., password management). The parameters are used to automatically perform the task using a centralized identity management system and repository for storing and updating data, such as data associated with customers, User Ids, environments, applications and application versions. Such a system and method enables the delegation of resource management tasks across multiple environments hosting disparate hardware and software platforms, including multiple versions of applications.

Abstract: Exemplary embodiments provide a computer-implemented method and a system for a startup cycle for a cycle deterministic start. An initializing mechanism applies power to a microprocessor. The initializing mechanism initializes the configuration of the microprocessor. The initializing mechanism initializes a timer. The initializing mechanism then sends a clock start command to the microprocessor. The clocks on the microprocessor are started. Upon the clocks starting, the timer begins and allows temporary transients, such as voltage droop due to a large instantaneous change in demand for current due to the commencement of clock switching. Responsive to the timer reaching a target value, an interrupt unit sends a system reset interrupt. Responsive to the interrupt unit sending the system reset interrupt, an instruction fetch unit fetches a first instruction. This operation will be deterministic to the state of the rest of the microprocessor memory elements (latches, arrays, et al.).

Abstract: A computer implemented method, apparatus, and computer program product for developing neuropsychiatric treatment plans. A treatment plan generator receives a set of diagnoses for a patient. The treatment plan generator automatically analyzes medical information in a set of electronic medical literature sources for potential therapies associated with treatment of each identified condition in the set of diagnoses. The treatment plan generator identifies the potential therapies associated with the treatment of each diagnosed condition. The treatment plan generator selects a set of recommended therapies from the potential therapies based on portions of the medical literature describing each therapy in the potential therapies and a medical history for the patient. The treatment plan generator generates a treatment plan. The treatment plan comprises the set of recommended therapies to treat each diagnosed condition in the set of diagnoses.

Abstract: Computer implemented method, system and computer usable program code for processing a data request in a data processing system. A read command requesting data is received from a requesting master device. It is determined whether a cache of a processor can provide the requested data. Responsive to a determination that a cache of a processor can provide the requested data, the requested data is routed to the requesting master device on an intervention data bus of the processor separate from a read data bus and a write data bus of the processor.

Abstract: Multiple logical partitions are provided in a data processing system. A unique context is generated for each one of the logical partitions. When one of the logical partitions requires access to the hardware TPM, that partition's context is required to be stored in the hardware TPM. The hardware TPM includes a finite number of storage locations, called context slots, for storing contexts. Each context slot can store one partition's context. Each one of the partitions is associated with one of the limited number of context storage slots in the hardware TPM. At least one of the context slots is simultaneously associated with more than one of the logical partitions. Contexts are swapped into and out of the hardware TPM during runtime of the data processing system so that when ones of the partitions require access to the hardware TPM, their required contexts are currently stored in the hardware TPM.

Abstract: A tracer object for tracing a user or process in a data processing system is provided. An application receives a tracer key containing a request for information to be traced. The received tracer key is checked against all tracer keys that the application has stored. If a match between two tracer keys is found, the stored tracer key maps the tracer key containing the request to the stored tracer key's associated tracer object and applies the conditions and modifiers contained in the tracer key containing the request to the tracer object. The tracer object then gathers the required information as requested.
