PUBLICATIONS r12.2_commands_subs.doc FILE Copyright (C) 1996 by Stratus Computer, Inc. Introduction ============ This file documents commands and subroutines that set, get, and display initial, current, maximum, and default limits for heap, stack, and total program size. It also documents the display_program_module command, which displays information about the authorship, history, and structure of a program module as well as information about its size. This file documents the following commands and subroutines: o General user commands: - list_process_cmd_limits - update_process_cmd_limits - display_program_module o System administration commands: - list_default_cmd_limits - update_default_cmd_limits o Subroutines: - s$get_current_cmd_limit - s$set_current_cmd_limit General User Commands ===================== This section documents three general user commands, list_process_cmd_limits, update_process_cmd_limits, and display_program_module. list_process_cmd_limits Purpose This command lists the heap, stack, and total space limits for commands executed by an existing process. Display Form --------------------------- list_process_cmd_limits -------------------------

process_name: -user: current_user -module: current_module Command Line Form list_process_cmd_limits [process_name] [-user user_name] [-module module_name] Arguments process_name The name or star name of existing processes for which you want to list the process initial and maximum command limits for total, heap, and stack usage by each new command that the process runs. By default, if the value of -user is current_user and the value of -module is current_module, the command lists the process limits of the current process. Otherwise, the default process name is an asterisk (*), indicating all processes of the specified user on the specified module. -user user_name Specifies a name or user star name indicating one or more user names for which you want to list the initial and maximum total, heap, and stack limits. By default, the command uses your user name. -module module_name Specifies the module on which the processes are running. By default, the command uses the current module. Explanation The list_process_cmd_limits command lists the initial and maximum total, heap, and stack limits for an existing process. The module default command limits are the initial and maximum limits that apply to a module. The system administrator specifies the module default command limits for all new processes on the module with the update_default_cmd_limits command. The process initial command limits limit the use of total, heap, and stack memory space by a program module unless the program module itself specifies a different limit. The process maximum command limits limit the maximum use of total, heap, and stack memory space by program modules executed within a process.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
