SOS System Configuration
The System Configuration screen is provided as a means to show significant system configuration parameters.


Figure 22.1 SOS System Configuration screen
To access the System Configuration screen from the global screen:
  • Type S from the SOS Enter command: prompt to view the Screen Selection Menu screen.
  • From the Screen Selection Menu screen, enter J (System Configuration Screen). The System Configuration screen will display. Figure 22.1 shows an example of the screen.
  • The screen is broken into the following sections:
  • System Configuration
  • Job and Session Information
  • Scheduling Information
  • More System Configuration information is available through two additional screens that are accessed via function keys under the System Configuration screen:
  • Globally Allowed Commands screen (Figure 22.1)
  • System Log Events Enabled screen (Figure 22.1)
  • System Configuration Screen Keys

    All of the System Configuration Screen keys are identical with the keys of the CPU Detail Screen. See "CPU Detail Screen Keys" for details.

    System Configuration Screen Display Items

    The System Configuration screen displays data about the system configuration, jobs and sessions, and scheduling.

    System Configuration

    Each data item in the System Configuration portion of the System Configuration screen is described in Table 22.1.
    Table 22.1 SOS System Configuration data items
    Data Item
    Description
    CPU Type
    The model of the computer system that runs the SOS/3000 Performance Advisor.
    Memory Size
    The amount of memory currently installed (megabytes).
    User Mode
    The current system operating mode. This option is either Single User or Multi-User.
    HPSUSAN
    This field represents the unique identifying number assigned to the CPU. This number is assigned by Hewlett-Packard for third-party vendors. This allows the vendors, including LPS, to tie their software to a particular CPU.
    Physical Console

    OS AIF Version
    The version number of the Operating System Architected Interface that is currently installed.
    MI AIF Version
    The version number of the Measurement Interface Architected Interface that is currently installed.
    Three messages can appear in the blank area of the System Configuration section. These messages are also in the Advice Section. They are described in the next table.
    Table 22.2 System Configuration Messages
    Message

    Max # J/S
    The configured maximum number of combined jobs and sessions.
    Job Limit
    The current setting of the MPE LIMIT for batch jobs.
    Sess Limit
    The current setting of the MPE LIMIT for interactive sessions.
    Streams Dev
    The logical device number of system STREAMS device.
    Max # Procs
    The configured maximum number of concurrently running processes for the system.
    Job Count
    The current number of executing batch jobs.
    Sess Count
    The current number of interactive sessions.
    Max # Open Files/Process
    The configured maximum allowable number of open files process.
    Next Job #
    The number to be assigned to the next batch job.
    Next Sess #
    The number to be assigned to the next interactive session.

    Scheduling Information

    Each data item in the Scheduling Information portion of the System Configuration screen is described in Table 22.4.
    Table 22.4 Scheduling Information data items
    Data Item
    Description
    Queue Base AS, BS, CS, DS, ES
    The base priority for the queue.
    Queue Limit AS, BS, CS, DS, ES
    The limit priority for the queue.
    Quantum CS, DS, ES
    The current queue quantum.
    CS Quantum Max
    The maximum allowable CS queue quantum.
    CS Quantum Min
    The minimum allowable CS queue quantum.
    Time Slice CS, DS, ES
    The amount of time allocated by the dispatcher for processes in queue before it recalculates its priority.
    Boost - DECAY
    If set, a process decays normally to the limit of the queue and returns to the base when the transaction is completed. DECAY is the default.
    Boost - OSCILLATE
    If set, a process is placed back to the base of the queue once its priority has decayed to the limit of the queue, even if it has not completed a dispatcher transaction.

    Globally Allowed Commands Screen

    This screen (Figure 22.2) shows all of the MPE commands that can potentially be globally allowed (i.e., allowed to all users). Access this display by pressing F4 - ALLOWED COMMANDS. Those commands within this list that have been highlighted in inverse with an "*" are currently globally allowed. (For a complete explanation of globally allowable commands, refer to the HP MPE/iX manuals.)

    System Log Events Enabled Screen

    This screen (Figure 22.3) lists all of the MPE System Log Events that can potentially be enabled. Access this display by pressing F5 - SYS LOG EVENTS from either the System Configuration screen or the Globally Allowed Commands screen. Items highlighted in inverse with an "*" next to it are currently enabled. For a complete explanation of system logging and its associated events, refer to the appropriate MPE/iX manuals.
