20090265691 | GRANULAR MEASUREMENT OF PROCESSOR PERFORMANCE IN EXECUTING SECTIONS OF SOFTWARE CODE - Processor performance in executing a section of software code is measured. A clock associated with the section of software code. It is detected that the section of software code is beginning to be executed. In response, the clock associated with the section of software code is started. It is then detected that the section of software code is no longer being executed. In response, the clock associated with the section of software code is stopped. The clock is stopped and restarted as the section of software code temporarily stops execution to cede control to other sections of software code. Ultimately, a value of the clock associated with the section of software code is output, where the value corresponds to the processor performance in executing the section of software code. | 10-22-2009 |
20120191701 | DATABASE INDEX PROFILE BASED WEIGHTS FOR COST COMPUTATION - Database tables can have different types of database indices defined for the database tables and different numbers of database indices. The efficiency of reading the indexes can vary with the different profiles of the indexes, which impacts the costs of access plans that use the indexes. Weights can be predefined to reflect the relative efficiencies of the different characteristics. Costs can be computed in accordance with a variety of techniques (e.g., based on edge traversals). The weights can be predefined to reduce costs, increase costs, or a combination thereof. A database management application or associated application or program can also refine or revise these weights based on statistical data gathered about the operation of the database and/or heuristics that are developed based on observations/research. The corresponding weights can be adjusted accordingly. | 07-26-2012 |
