The AUTOGEN command procedure (SYS$UPDATE:AUTOGEN.COM) sets appropriate values for system parameters and sizes for system page, swap, and dump files. AUTOGEN runs automatically when you install or upgrade the operating system. In addition, you can use AUTOGEN to reset system parameter values, system file sizes, or both. The new values and file sizes take effect the next time the system is booted. Compaq recommends that you run AUTOGEN on a weekly basis to adjust system parameters according to your system's work load. AUTOGEN executes in phases, with each phase performing a separate task. You control which tasks AUTOGEN performs by specifying a start phase and an end phase when you invoke AUTOGEN. You can add commands to the file SYS$SYSTEM:MODPARAMS.DAT to control the system parameter values and file sizes that AUTOGEN sets. AUTOGEN uses the information in this file to determine final values for system parameters or page, swap or dump file sizes. AUTOGEN can improve system performance by using dynamic information, called feedback, which is gathered from the running system. NOTE When making major configuration changes, do not use feedback. Specify nofeedback to assure the use of the initial AUTOGEN settings. You control how AUTOGEN uses feedback by specifying an execution mode when you invoke AUTOGEN. To direct AUTOGEN to use feedback to make its calculations, run AUTOGEN in feedback mode. After a period of time, you can execute AUTOGEN in feedback mode to further refine system parameter settings.
