A software system is disclosed which facilitates the process of tracing the execution paths of a program, called the client. The tracing is performed without requiring modifications to the executable or source code files of the client. Trace data collected during the tracing operation is collected according to instructions in a trace options file. At run time, the tracing library attaches to the memory image of the client. The tracing library is configured to monitor execution of the client and to collect trace data, based on selections in the trace options file. Conditional tracing, through the use of triggers and actions taken in response to the triggers, allows the developer to control the tracing operation. The triggers can be conditional triggers in which the corresponding action is taken only if a conditional expression is satisfied. The system can trace multiple threads and multiple processes. The tracing system provides a remote mode and an online mode. In remote mode, the developer sends the trace control information (which can include triggers and corresponding actions) to a remote user site together with a small executable image called the agent that enables a remote customer, to generate a trace file that represents execution of the client application at the remote site. In online mode, the developer can generate trace options (including triggers and corresponding actions), run and trace the client, and display the trace results in near real-time on the display screen during execution of the client program.

A file system may selectively perform redundancy consistency recovery and synchronization of mirrors and may store dirty file information in a log or journal that indicates the modification of a file. A file system may update saved dirty file information to indicate successful modification of data across mirrors and may keep track of redundancy consistency recovery information on a file-by-file basis or may track the redundancy consistency of portions of files. A file system may also instruct an underlying storage system not to track data modifications, possibly selectively for each I/O request. During synchronization the file system may synchronize its log and use saved dirty file information to determine files to be synchronized. A file system may selectively use file system logging for individual data modification requests and may expose an API allowing applications to specify a redundancy consistency mechanism.

A method for managing data in a semiconductor processing environment. Raw data is collected during a process. Also, trace file data and process log file data are received. The raw data is synchronized with the trace file data and process log file data to create wafer data summary data is calculated from the raw data and a file is created containing the wafer data and the summary data.

A method and system for tracing the failing or successful execution of nested functions coded with return codes in a thread during its execution. The method comprises an ENTRY and EXIT trace macro to mark the beginning and the end of execution of the function, a TRACE macro to record messages and program variable values, and a QUIT macro marking the failing execution of the corresponding function. Using a Graphical User Interface, an interactive trace analyzer reads the trace file and displays the tree structure of the nested functions and marks, by using different colors, the success or failure of each of them. The trace analyzer utilities help the user to quickly identify the error in the source code corresponding to a function with a failing execution.

System and method for tracking statistics at the subfile level and transparently placing or migrating inactive or less active blocks of data to other storage devices. Embodiments may provide mechanisms to track statistics at the subfile level of files including, but not limited to, database files, and to transparently place or migrate inactive or less active blocks of data of the files from higher-performing, typically more expensive, storage to lower-performing, typically less expensive, storage, while placing or migrating active blocks of data of the files to higher-performing storage, based on the subfile-level statistics rather than on file-level timestamps. In some embodiments, knowledge of file structure (e.g., database file structure), for example knowledge of database partitions with header blocks and data blocks in databases using data partitioning, may be used to separate more active and less active blocks of data of files onto storage with different performance and/or other characteristics.

The method involves a periodic retrieval of an error log from the data processing device, a comparison of two or more retrieved error logs, and a retrieval of the trace file(s) from the data processing device based on the comparison of the two or more retrieved error logs indicating an occurrence of one or more soft errors within the data processing device.

A system, method and program enabling users to diagnose applications easily without affecting the operating performance of the application server, optimizing the log mechanism based on the integrated development environment. The method includes running the application in a main running environment and at least one shadow environment, the shadow environment obtained by duplicating the main running environment; and the main running environment interacting with the shadow environment with respect to the fault of the application. The method includes performing the steps of the main running environment: monitoring the exceptions in the system and sending system exception information to the shadow environment in the event of finding exceptions in the system. The shadow environment: receives the system exception information, opens diagnostic log/trace functions to obtain diagnosis log/trace files related to the system exceptions, and analyzes the diagnosis result based on the obtained diagnosis log/trace files.

The present invention describes methods, systems, and data structures to create and search index records within a trace of a packet-based communications link that has been compressed by organizing the data packets according to which flow they belong. Index points are inserted within the compressed flow trace file to create frames and index records are created and saved for each index point. Consequently, searching for a particular data packet does not require sequentially reading the compressed flow trace file, but rather locating the appropriate index record and its corresponding frame in the compressed flow trace file.

A computer-implemented method and system for automatically invoking a predetermined debugger command at a desired location of a single thread of a program containing at least one thread. At the desired location of the program thread, there is embedded a utility which reads a trace file in which the predetermined debugger command has been previously embedded. Upon re-running the program, the trace file is read and upon reaching the predetermined debugger command, the debugger attaches itself to the running process and executes the process from its current program counter. The debugger is invoked only if there is a discrepancy between successive runs of the program.
