Abstract: A system, method, and product are disclosed for testing multiple threads simultaneously. The threads share a real memory space. A first portion of the real memory space is designated as exclusive memory such that the first portion appears to be reserved for use by only one of the threads. The threads are simultaneously executed. The threads access the first portion during execution. Apparent exclusive use of the first portion of the real memory space is permitted by a first one of the threads. Simultaneously with permitting apparent exclusive use of the first portion by the first one of the threads, apparent exclusive use of the first portion of the real memory space is also permitted by a second one of the threads. The threads simultaneously appear to have exclusive use of the first portion and may simultaneously access the first portion.

Abstract: A method, apparatus, and computer instructions for managing data in a file system in a data processing system. A request to modify a data block in the file system is detected during file system recovery time. In response to detecting the request, metadata is written to describe the data block into a snapshot image. The data is copied for the data block in the file system to the snapshot image. The data block is modified in the file system after the data is copied into the snapshot image. The snapshot image may be used to return the file system to a state prior to modifying the data block in the file system.

Abstract: A method, system, apparatus, and computer program product are presented for processing Web page documents to determine the availability or unavailability of in-line resources within a Web page. A transaction monitor receives an indication from a Web browser that a Web page has been retrieved, after which the transaction monitor examiners a document object model maintained by the Web browser for the retrieved Web page. The transaction monitor determines whether the document object model indicates that a set of one or more in-line resources in the retrieved Web page is unavailable, and in response, the transaction monitor generates an unavailability indicator for an unavailable in-line resource. The unavailability indicator may be signaled through an appropriate software event, placed in a statistical database, or presented on a display as graphical information for a user of the transaction monitor.

Abstract: A method is presented for correlating related transactions, such as a parent transaction that invokes a child transaction within a distributed data processing system, using a particular format for the correlation tokens. Each transaction is associated with a correlation token containing a hierarchical, three-layer identifier that includes a local transaction identifier and a local system identifier, which are associated with the local system of the child transaction, along with a root transaction identifier, a root system identifier, and a registry identifier. The local transaction identifier is unique within the local system, and the local system identifier is unique within a registry that contains a set of system identifiers. The registry is associated with a domain in which the local systems operate, and multiple domains exist within a transaction space of entities that use these correlation tokens. Correlation token pairs are analyzed to construct a call graph of related transactions.

Abstract: A workload scheduler supporting the definition of a cumulative weighting index is proposed. The scheduler maintains (384-386) a profile for each job; the profile (built using statistics of previous executions of the job) defines an estimated usage of different resources of the system by the job. A tuning module imports (304) the attributes of the jobs from the profile. The attributes of each job are rated (306-307) according to an estimated duration of the job. The rated attributes so obtained are then combined (308-320), in order to define a single cumulative index for each job and a single cumulative index for each application (for example, weighting the rated attributes according to corresponding correction factors). In this way, the cumulative indexes allow an immediate comparison (324-356) of the impact of the different jobs/applications of a plan on the whole performance of the system.

Abstract: A method, apparatus, and computer program product are disclosed in a processor for dynamically, during runtime, allocating memory for in-memory hardware tracing. The processor is included within a data processing system. The processor includes multiple processing units that are coupled together utilizing a system bus. The processing units include a memory controller that controls a system memory. A particular size of the system memory is determined that is needed for storing trace data. A hardware trace facility requests, dynamically after the data processing system has completed booting, the particular size of the system memory to be allocated to the hardware trace facility for storing trace data that is captured by the hardware trace facility. The firmware selects particular locations within the system memory. All of the particular locations together are the particular size. The firmware allocates the particular locations for use exclusively by the hardware trace facility.

Abstract: A web browser magnifies the content of the whole page in memory and displays the relevant portion in a magnifier with hyperlinks. The web browser then maps the magnified display to the original document. Thus, manipulation of the mouse in the magnified display may result in an action with respect to the original document. The user may then select a link for navigation within the magnified display. Alternatively, the web browser may analyze the original web page and construct magnifier contents on the basis of either the document object model, extensible markup language (XML), or hypertext markup language (HTML) representation of the magnified portion.

Abstract: System, method and program product performed by a proxy server which forwards an access request from a client to a data server and forwards response data from the data server to the client. A first address location and an encoding format of the response data are stored. A subsequent access request from the client which includes a second address location encoded by the encoding format is received. The second address location is compared to the first address location to determine if the second address location is related to the first address location. In response to a determination that the second address location is related to the first address location, the second address location is decoded based on the encoding format. The data server can be a web server, the response data can be a web page, and the second address location can include the first address. For example, the second address location can be an extension of the first address location.

Abstract: A method, system, and computer instructions for atomically updating 64-bit fields in the 32-bit AIX kernel, wherein the underlying hardware's 64-bit capable instructions are used to construct an atomic primitive. If a data request applies to the 32-bit kernel on 64-bit hardware execution environment, a load and reserve instruction sets a reservation for a memory location. The original 64-bit data object is decomposed into two 32-bit halves. A Shift Right Double Word Immediate (SRDI) instruction captures the high-order bits of the 64-bit register. If the store conditional instruction determines that the reservation is not lost, the store conditional instruction stores the result. If the store conditional instruction fails, the process returns to the reserve instruction until the store conditional operation returns a success.

Abstract: A method is disclosed for collecting data about the transmission of network packets that are associated with specified applications. The packets are transmitted through a communications network fabric that is used to couple data processing systems together. A particular existing single bit in a frame header definition is selected. The bit is defined as part of the standard frame header by a communication protocol as an available bit in the frame header. The standard protocol is unchanged by the selection of this bit. An application is specified to be monitored. The selected bit is then set in each network packet that is generated by the specified application. The fabric collects performance data for each packet that has the bit set. Thus, the fabric collects performance data about a transmission of each packet that is generated by the application when that application is setting the bit.

Abstract: A remote user, two-way authentication and password change protocol that also allows parties to optionally establish a session key which can be used to protect subsequent communication. In a preferred embodiment, a challenge token is generated and exchanged which is a one-time value that includes a random value that changes from session to session. The construction and use of the challenge token avoids transmission of the password or even the transmission of a digest of the password itself. Thus the challenge token does not reveal any information about a secret password or a digest of the password.
