摘要:
An apparatus and method define the concept of a “database breakpoint.” One or more conditions in the database are specified as a database breakpoint in a debug environment for debugging a computer program that accesses the database. When the database conditions exist, one or more debug functions may be performed with respect to the execution of the computer program. Examples of debug functions include halting execution of the computer program and halting operations to the database by other programs. With both the computer program and database halted, the user may then interrogate the database to determine its state, and may interrogate the program to determine its state. Database breakpoints greatly enhance the utility of a debugger by providing additional conditions for debugging a computer program that accesses a database.
摘要:
A method and system for allocating and storing data to a cache memory in each processor in a multiprocessor computer system. Data structures in main memory are partitioned into substructures that are classified as either exclusive substructures or sharing substructures. The exclusive substructures are cached exclusively by a specified processor, and the sharing substructures are cached by specified groups of processors in the multiprocessor computer.
摘要:
Diagnostic data, such as a time increment corresponding to how long a thread waits to access a shared resource, is stored within a predetermined location in a data structure, such as a hash bucket in a hash table. The location is preferably correlated to the resource such that a display of the diagnostic data may be tailored to reflect a user-specified relationship between the data and resource.
