Abstract: Diagnostic data-collection software is triggered by a fault in application software running on a client computer. Data gathered by the diagnostic software is transmitted to a computer system of a service vendor. Analysis software running on the vendor system analyzes the diagnostic data and generates recommendations. The recommendations are posted on a vendor-managed website. The client is informed by email of a URL to access the recommendations. After a validation procedure, the client can access the recommendations. The recommendations can include instructions for a human to execute as well as software to be downloaded to the client computer.

Abstract: A system and method for profiling the execution of a software library used by an application, creating an optimized library based on the profiling, and updating to the optimized library without halting the application. The application is running using an unoptimized version of a replaceable library. The replaceable library is profiled while being used by the application and produces a set of profile data. The profile data, generated by actual execution of the replaceable library on the end-user application, is used to create an optimized version of the library. The application can then update from the unoptimized version of the library to the optimized version of the library. The invention also allows for a system with several applications, each using a different version of an optimized library simultaneously, each optimized version of the library custom optimized for the application using it.
