Abstract: Methods, systems, and media are disclosed for handling errors resulting in error messages while executing a script file such as a Sequential Query Language (SQL) script. Embodiments may include one or more databases such as databases interconnected via a network, which include or have the ability to create and/or execute script files with on-error statements. Script files with on-error statements may include an error identifier and a resolution identifier. Each error identifier may identify one or more errors associated with the resolution identifier and the resolution identifier may identify a way to handle the error. Resolution identifiers may provide one or more error-recovery statements, calls for execution of a stored procedure, or other functions to correct, log, or ignore errors and continue or terminate execution of script files. Many embodiments include a command line processor that can recognize and implement the on-error statements.

Abstract: Systems and methods for handling the event of a wrong branch prediction and an instruction rejection in a digital processor are disclosed. More particularly, hardware and software are disclosed for detecting a condition where a branch instruction was mispredicted and an instruction that preceded the branch instruction is rejected after the branch instruction is executed. When the condition is detected, the branch instruction and rejected instruction are recirculated for execution. Until, the branch instruction is re-executed, control circuitry can prevent instructions from being received into an instruction buffer that feeds instructions to the execution units of the processor by fencing the instruction buffer from the fetcher. The instruction fetcher may continue fetching instructions along the branch target path into a local cache until the fence is dropped.

Another embodiment comprises a male connector with discharge elements, which ground conductors of the cable as the cable is being inserted into the connector. The discharge elements are pushed out of the way of the conductors as the conductors couple with the connector.

Abstract: Test patterns for testing electrical circuits are generated by a MUX having its output operatively coupled to a Scan-In shift register and inputs receiving seed pattern signals, response signal from a response shift register, positive and negative signals from the Scan-In register. A control logic circuit provides control signals that enable the MUX to select appropriate input signals. The circuit arrangement enables relatively few seed patterns to generate relatively large number of test patterns. The seed patterns are a sub-set of a test pattern set preferably generated by software such as the Automatic Test Pattern Generator (ATPG). A method to generate the seed patterns is, also, provided.

Abstract: The decision within a packet processing device to transmit a newly arriving packet into a queue to await processing or to discard the same packet is made by a flow control method and system. The flow control is updated with a constant period determined by storage and flow rate limits. The update includes comparing current queue occupancy to thresholds and also comparing present queue occupancy to previous queue occupancy. The outcome of the update is a new transmit probability value. The value is stored for the subsequent period of flow control and packets arriving during that period are subject to a transmit or discard decision that uses that value.

Embodiments include supplying a chilled fluid to a cold plate at a first flowrate, where the first flowrate is associated with a first valve setting based on at least a desired temperature setpoint and an applied power. Embodiments may determine a change in applied power and modify the chilled fluid flowrate in response to a change in testing conditions to a second flowrate associated with a second valve setting associated with at least the desired temperature setpoint and the changed testing conditions. This feed forward loop may be supplemented by a feedback loop that includes modifying the energy supplied to a cold plate heater in response to a comparison of a current temperature and the temperature setpoint. The valve may be a proportional control valve or the like.

One embodiment includes receiving a request by the application, wherein the request constitutes an action a user seeks to perform on the resource, and adding a number of instance identifier fields to an mbean descriptor file associated with the mbean.

Further still, the embodiment includes reading the mbean descriptor file after the populating, and determining, based on the reading, whether the user has an authority to perform the request. If authority exists, then an mbean method performs the action on the resource, and filters the obtained results to coincide with the user's authority.
