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	The logical device number to which the console device is attached.
Logical Console	The logical device number to which the console is currently assigned via the CONSOLE command.
MPE/iX Version	The version of MPE/iX currently running.
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	Description
Disc Space Low	Disc space is too low to log processes on.
Out of Resources	Certain System resources are not available (tables, etc.)
Out of LDEVS	LDEV ports are not available.

Job and Session Information

Each data item in the Job and Session Information portion of the System Configuration screen is described in Table 22.3.

Table 22.3 Job and Session Information data items

Data Item	Description
Jobfence	The current setting of the MPE JOBFENCE.
Outfence	The current setting of the MPE OUTFENCE.
Jobsecurity	The current setting of the MPE JOBSECURITY keyword. The options are LOW or HIGH.
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.)

Figure 22.2 SOS Globally Allowed Commands screen

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.
