Abstract: Embodiments presented herein provide techniques for generating analytical graphs that display a visualization of multiple transaction objects processed concurrently in a computer system. An object lifecycle analysis tool identifies one or more transaction objects having a specified identifier. Each transaction object corresponds to an instance of a common transaction having been processed. The analysis tool retrieves transition state information corresponding to each transaction object and sorts the transition state information in chronological order. The analysis tool generates a graph based on the sorted transition state information. The generated graph allows a user to easily identify performance issues (e.g., concurrency bottlenecks) in a transaction management system.

An object lifecycle analysis tool identifies one or more transaction objects having a specified identifier. Each transaction object corresponds to an insance of a common transaction having been processed. The analysis tool retrieves transition state information corresponding to each transaction object and sorts the transition state information in chronological order. The analysis tool generates a graph based on the sorted transition state information.

Abstract: A peripheral interface device that is adaptable into a computer system and which provides a communication interface for a plurality of external devices. The peripheral interface device comprises: a plurality of transfer control logic (TCL) modules, wherein each TCL module provides a dedicated interface for an associated one of the external devices, and wherein multiple TCL modules can communicate in parallel with their associated external devices; and a dual port memory (DPM) device that is in communication with an input/output bus of the computer system, wherein the DPM device can selectively communicate with each of the plurality of TCL modules.

Abstract: A power adapter for powering a remote device for use with a portable computer. The power adapter has a first plug for connecting to a data port of the portable computer and for sourcing power from the data port. Also provided is a power converter electrically connected to the first plug for regulating the sourced power from the data port and outputting a power requirement to the remote device. Lastly, a second plug electrically connected to the power converter for connection to the remote device and delivery of the outputted power requirement thereto is provided. Also provided is a portable computer system which utilizes the power adapter of the present invention. The portable computer system comprises a portable computer having a data port, a remote device for use with the portable computer, and the power adapter of the present invention for powering the remote device through the data port.
