Abstract: Separation of parameterized unit tests (PUTs) from specific test cases supports many benefits including automated test case generation. Symbolic execution assigns symbolic input variables to parameters of a parameterized unit test. Path constraints of an implementation under test (IUT) are identified during symbolic execution. A constraint solver automatically generates test cases by determining the test inputs that satisfy one of more paths, each described by constraints, through the IUT. PUTs are used to populate behavioral summaries. Behavioral summaries are used later in future symbolic executions to emulate summarized methods. Behavioral summaries comprise behavioral purity axioms. Behavioral purity axioms require that an intensional heap before execution of a PUT be equal to the intensional heap after execution. An intensional heap is provided to represent state changes performed by summarized methods. The extensional heap is used to explicitly update memory locations, e.g.

A CPU of the apparatus accepts processing requests from the host computers. When accepting a processing request from a host computer, the CPU causes the apparatus to connect to the host computer. If occurrence of an error is detected during communication with the host computer, the CPU controls the connection such that reconnection to the host computer connected at the time of occurrence of the error is given priority over connection to another host computer.

Abstract: The disk controller has a plurality of channel control units, a plurality of cache memories, a plurality of disk control units, and a plurality of internal switch units. Each channel control unit or disk control unit sends to one of the cache memory units a request packet requesting execution of processing. The cache memory unit sends a response packet in response to the received request packet. Each internal switch unit monitors the request packet sent from the channel control unit or disk control unit, and judges whether or not the response packet to the request packet has passed through the internal switch unit within a first given time period since the passage of the request packet. In the case where the response packet has not passed through the internal switch unit within the first given time period, the internal switch unit sends a failure notification.

Abstract: Flow information records are identified and sorted out based on the sending and/or receiving customer. Prior art problems are overcome by using a combination of router identification, SNMP numbers and interface numbers to identify the source and destination of data flow records. A flow information packet containing one or more information flow records is received at a flow process and parsed to identify the router source. The datagram of the flow information packet is examined to identify an SNMP number associated with the source and/or destination affiliated with the flow information packet. Based on the SNMP number, the interface of the router associated with the datagram is identified and the records are accordingly sorted into buckets. The total traffic through the router interface for a period of time is obtained via an SNMP query and the data apportioned to a bucket is scaled based on the results.

Abstract: A method and system for automatically cloning IT resource structure in stateful web services environments by employing a new approach for configuration management. The present new approach models the configurational state of each resource as a stateful web service. Configuration data are provided by this service's resource properties. Relationships between configurations of different resources are modeled as “stateful web services relationships” between web service instances. These relationships can be navigated, which allows exploring the configuration of a whole system in a standards-based way. Additionally a new web service interface is provided by the stateful web service encapsulating the resource. This interface provides two new operations: “getConfiguration” allows an exploiter to take a snapshot of a resource's and related resources' configurational state and “setConfiguration” allows for setting the configurational state of a resource to a previously saved state.

The necessity of the integrity verification processing is determined by reading out the status information indicating the necessity of the integrity verification processing. When the integrity verification processing is determined to be necessary, the integrity verification processing is carried out for unverified recording status information of the recording status information of the space bit map.

Abstract: A method and system for overriding state information programmed into a processor using an application programming interface (API) avoids introducing error conditions in the processor. An override monitor unit within the processor stores the programmed state for any setting that is overridden so that the programmed state can be restored when the error condition no longer exists. The override monitor unit overrides the programmed state by forcing the setting to a legal value that does not cause an error condition. The processor is able to continue operating without notifying a device driver that an error condition has occurred since the error condition is avoided.

Abstract: A method for guaranteeing consistency of functional parts across a software installation in a computer that is platform and language independent. Specifically, each software installation will contain a part, for example a DLL that exports a function or variable, which is available to other parts in the installation. All other parts in the installation, for example, executable files and other DLLs, will reference the exported resource. The name of the exported resource should evoke a particular software level and be specific to the software installation it belongs to. All other software installations on the same computer will follow this practice. Thus, all parts in a software installation will effectively reference a software level (via an exported resource). When the multiple parts of software are loaded into computer memory prior to execution of the software, the operating system will attempt to resolve references to the exported resource.

Abstract: Disclosed is a method for processing a DCD content in a DCD (Dynamic Content Delivery). When a DCD content is delivered between a server and a terminal in a DCD service system, a client of the terminal delivers the DCD content to a DECA (DCD Enabled Client Application) of the terminal. If the DECA cannot play (execute) the content, the DECA sends to the client an error notification message and a generated status value (information about device capabilities of the terminal), and the client sends the error notification message and the status value to the server. Accordingly, if an error informing that the content received from the server cannot be played has occurred, the error is processed between the terminal and the server from the point of the terminal.

Abstract: Apparatus methods for capturing flow control errors in FIFO exchanges between producing and consuming circuits operating in different clock domains. Tag information at the start of an exchange is transferred to a synchronizing component before data of a transfer transaction is entered in the FIFO. The tag information is also associated with each unit of data transferred to the FIFO by the producing circuit. The synchronizing component verifies the each unit of data retrieved by the consuming circuit has the expected tag information associated therewith and signals an error is the tag information does not match. Thus an error by the producing circuit in entering too much or too little data for a transfer is detected before erroneous data is retrieved and processed by the consuming circuit.
