Abstract: A method for managing multicast groups with send-without-receive (SWR) joiners without the use of traps on creation and deletion of groups is provided. Group information is maintained continuously while the SWR member exists. When an SWR join is attempted and the group does not already exist, the group information (MLID) is marked as used and the first switch to which the SWR packets are sent is routed to discard all packets sent to the group. When receiving members join the group, the routing is updated so that the SWR member begins sending to the receiving members. When the last receiving member leaves the group, the first switch is again routed to discard the packets.

Abstract: A method is presented for pruning a peer-to-peer network such that a peer-to-peer search within the peer-to-peer network is initiated beginning with those nodes on which relevant content has previously been found for particular search keywords. For each completed search, a peer node gathers client rating results and then forwards the rating information to a rating server; these results reflect the degree to which searches successfully located content for keywords in a search using particular peer nodes. A rating server maintains a database of results received from nodes. Prior to initiating a new search at a peer node, the peer node consults one or more rating databases to retrieve a set of initial nodes to which the node should initiate the new search in order to maximize the speed and success of finding relevant content. The node then performs the new search using the set of initial nodes.

Abstract: A method is presented for employing radio frequency (RF) identifier (ID) transponder tags (RFID tags) to create a unique identifier, termed an RFID signature, for use within a data processing system with respect to a person or an object. An interrogation signal is transmitted toward a person or an object with which a set of one or more RFID tags are physically associated. A first set of RFID tag identifiers are obtained from an interrogation response signal or signals returned from the set of one or more RFID tags. A mathematical operation is performed on the first set of RFID tag identifiers to generate an RFID signature value, which is employed as an identifier for the person or the object within the data processing system with respect to a transaction that is performed by the data processing system on behalf of the person or the object.

Abstract: In a method and system for monitoring events occurring at respective servers of a configuration of nodes, a first server located at a first node receives information from a messaging system pertaining to events at servers located at other nodes. The messaging system usefully comprises a highly available (HA) bulletin board or the like. When the first server receives a start event notification pertaining to a second server located at a second node, a direct communication path is established between the first and second servers. The first server identifies events in the second server that affect or are of interest to services of the first server. The first server then registers with the second server, to receive notification through the direct communication path when respective identified events occur.

Abstract: A translation method reduces the time required for display of the translation of a web page. Original document data is obtained to display an original document on a computer. The original document data is examined for the presence of saved data. When the saved data is present, instruction data is generated for instructing the acquisition of the saved data, and the instruction data is transmitted to a client across a network. Translation data is obtained for the original document. The obtained translation data is transmitted to the client across the network. Before examining for the presence of the saved data, an acquisition is instructed for the translation data of the original document.

Abstract: A system and method for implementing XSL/XML based authorization rules policy on a given set of data. An authorization rules engine is created which uses authorization rules defined in XSL to operate on access decision information (ADI) provided by the user. Inside the authorization rules engine, a boolean authorization rules mechanism is implemented to constrain the XSL processor to arrive at a boolean authorization decision. By applying the constrained authorization rules, the authorization rules engine evaluates available ADI data from an ADI XML input document. An output from a set of predetermined authorization decisions is provided to the user when the ADI input data is successfully evaluated. An error message is also provided to the user if required ADI data is unavailable for evaluation.

Abstract: A method to identify database triggers in a data processing system. A request is received to create a database monitor for a specific application event and in response to receiving the request to create the database monitor, the database monitor is created. Then, a request is received to monitor the specific application event within a database and in response to receiving the request to monitor the specific application event, a replicate database of the database is created. Subsequently, the database is compared to the replicate database after the specific application event occurs to identify changes in the database associated with the specific application event. A best candidate is identified for a database trigger based upon the identified changes in the database associated with the specific application event.

Abstract: A method in a data processing system for detecting and reducing database contention and deadlock caused from within an application server. A determination is made as to whether a set of parameters in a statistical model indicates contention. If the set of parameters in the statistical model indicates contention, an application server administrator is notified of the contention and the number of threads in an application server pool is reduced. If the set of parameters in the statistical model indicates contention is reduced, the number of threads in the application server pool is increased.

Abstract: A method, apparatus, and computer program product are disclosed in a data processing system for providing a virtualized time base in a logically partitioned data processing system. A time base is determined for each one of multiple processor cores. The time base is used to indicate a current time to one of the processor cores for which the time base is determined. The time bases are synchronized together for the processor cores such that each one of the processor cores includes its own copy of a synchronized time base. For one of the processor cores, a virtualized time base is generated that is different from the synchronized time base but that remains synchronized with at least a portion of the synchronized time base. The processor core utilizes the virtualized time base instead of the synchronized time base for indicating the current time to the processor core. The synchronized time bases and the portion of the virtualized time base remaining in synchronization together.

Abstract: A method, system and computer program product are provided to allow the status of components obtained through JMX queries to be loaded asynchronously in web content such that the status value of each component is displayed as soon as it becomes available, without having to wait for the completion of any other query.

Abstract: A method for providing remote access redirect in a host channel adapter of a system area network are provided. The method provides a mechanism by which a host channel adapter, in response to receiving a marker message, places selected channel(s) of the host channel adapter in a remote access redirect (RAR) mode of operation. During the RAR mode of operation, memory access messages received by the host channel adapter that are destined for portions of an application memory space marked as being protected are converted to RAR receive messages and redirected to a queue pair associated with an operating system rather than the queue pair for the application. The operating system is responsible for serializing access to application memory pages outside of the host channel adapter. The mechanisms of the present invention may be used to perform a checkpoint data integrity operation.

Abstract: A method, apparatus, and computer instructions for conducting an inventory of a data processing system. When a basic input output system (BIOS) is launched during a boot process for the data processing system, the basic input output system creates a hardware report of the data processing system. This report is sent to a remote data processing system on the network.

Abstract: A physical token is provided that is used to assign an activity or role to a specific device by virtue of a physical relationship with the device. By associating the token with a device, through electrical connection or by mere proximity relative to the device, an administrator informs the device of the intended role for the device in an enterprise. In conjunction with some bootstrapping or other appropriate software on the computing device, the act of placing the token in the proper physical relationship with the device is all that is necessary to configure and deploy the device in a data center. A device may be assigned roles from a plurality of tokens. Computing devices may also be assigned roles based upon their proximity to other devices. Roles may also include a concept of seniority, wherein one device may be assigned a more senior role to another device.

Abstract: The invention controls the persistence of server component objects during a transaction, thereby minimizing the number of times that a program accesses a database. The invention also minimizes the number of operations needed. The invention caches the database operations required to persist server component objects until a client object program commits the transaction or until the program needs to access the server component objects. The invention comprises an improved container program that creates server component objects, associates each server component object with a transaction, maintains the server component objects in a cache, filters out unnecessary database operations and then flushes the cache at the appropriate time so that a server component object is persisted only when a client program commits an associated transaction or another object attempts to access the server component object.

Abstract: A network service allocation device including a probe, a module, and an engine. The device collects performance data relating to the physical characteristics of a distributed data processing system. The module utilizes the performance data to identify two or more node clusters on the distributed data processing system. The engine correlates the node clusters and one or more performance rules as related to the network service to provide a map of node cluster(s) for supporting the network service, or a list of one or more servers within a node cluster for supporting the network service.

Abstract: A system and method for analyzing Java thread deadlocks. A snapshot of threads in a Java Virtual Machine is generated, producing a thread dump file which can be analyzed off line. The thread dump file is optimistically parsed to identify threads which are deadlocked. A user is provided with an interface to select filtering rules for the threads, resulting in a set of filtered threads which are candidates for being in infinite wait conditions.

Abstract: A system for identifying a subset of sensors to sample to reduce the frequency of sensor access. The system determines rise times and records values for the sensors in the system. A time criticality of the sensors is determined based on the rise times. The system processes the sensors by first creating sensor subsets based on one or more constraints on the sensors. The system monitors the values of the sensors in a sensor subset and flags a sensor when it makes a determination that, prior to a next scheduled sampling of the sensor subset, the value of a sensor in the monitored sensor subset will exceed a threshold constraint. The system moves those flagged sensors to a second sensor subset which complies with the sensor's constraints.
