摘要： A system and method for instrumenting program instructions. A processing system includes a compiler and a profiler. The compiler is configured to notify the profiler of a compilation event corresponding to first program instructions. In response to detecting the event, the profiler is configured to intercept compilation of the first program instructions, determine whether an instrumented version of the first program instructions is currently available, instruct the compiler to compile the instrumented version of the first program instructions if available, and retrieve and instrument the first program instructions if not available. The profiler may maintain an instrumentation cache for storing instrumented versions of program instructions. The instrumentation cache may further include metadata which identifies portions of program code which have been instrumented and their location. The profiler may generally instrument program instructions once during the resident life of a corresponding application.

摘要： A system and method for managing the environment of software processes in a computer system. A computer system comprises a processor and at least one process environment comprising one or more environment variables. The processor executes one or more processes, intercepts the launch of a process, sets at least one environment variable to a first value, and continues the launch of the process. Setting the environment variable may enable a profiler process. The processor may set at least one environment variable for the process to a value which is chosen irrespective of a value of the environment variable of a parent process of the process. Further, the processor may set at least one environment variable for the process to a default value if a data repository does not contain an entry that has an identification which corresponds to the process.

摘要： A method, system and computer readable code for instrumenting code into database access modules are disclosed. According to some embodiments, specific functions within the database access module are identified as query-execution functions, and instructions for logging at least one of database access strings and database connection string during runtime are instrumented into the identified query-execution functions. Exemplary database access strings include database query strings, such as an SQL query string, and stored procedure names. Optionally, additional instructions for extracting various parameters, such as database identifiers, performance parameters, and security policy parameters, from the database connection strings are instrumented. According to some embodiments, the identifying of query-execution functions includes determining if an identity of a candidate function of a database access module matches one of the identifiers of a known execution function. According to some embodiments, a repository of known query execution functions and/or a repository of encoding schema for database connection strings is maintained, for example, using one or more configuration files.
