Abstract: A method and system for dynamically quiescing applications in which the response time of a back end is measured and a front end application is disabled if the back end response time is too long and a sufficient number of instances of non-responsiveness have occurred in a given period. The front end application is disabled to prevent non-responsiveness and potential crashing of the web server, and then is reenabled (unquiesced) after a period of time.

Abstract: A method and apparatus for identifying and detecting hazards is presented. An executable specification for the architecture is compiled that includes macroarchitecture and microarchitecture information corresponding to each of the instructions supported by the architecture. A table (20) is constructed from the executable specification that specifies the particular resource utilization parameters associated with each of the instruction types included in the instruction set supported. From this table a resource utilization parameter list (30) is compiled that indicates the relative times at which resources are needed by each instruction and when these resources are released by the instruction. Comparisons between different entries in the resource utilization parameter list corresponding to the same resource are performed such that potential hazards are detected.
