System Values Perf Attributes

The System Values Perf attribute group contains attributes that you can use to monitor the configuration values for performance.


ORIGINNODE The host name for the monitored system. The valid value is an alphanumeric string with a maximum length of 64 characters.

QHSTLOGSIZ The maximum number of records for each version of the history log. The valid value is an integer in the range 1 through 32767.

QINACTITV Specifies the inactive job time-out interval in minutes. It specifies when the system takes action on inactive interactive jobs. The valid values include:

*NONE

The system does not check for inactive interactive jobs.

A number in the range 5 through 300

The value indicates the number of minutes that job can be inactive before the action is taken.

QINACTMSGQ The system value for the inactive message queue. The valid values include:

An alphanumeric string

There is a maximum of 20 characters. The list can contain up to 2 10-character values where the first is the message queue name and the second is the library name.

DSCJOB

The interactive job and any jobs associated with are disconnected.

ENDJOB

The interactive job and any jobs associated with it are ended.

QMAXSGNACN Specifies the action taken when the maximum number of consecutive incorrect sign-on attempts is reached. The valid values include:

*DEV

If limit is reached, varies off device.

*PRF

If limit is reached, disables user profile.

*DEVPRF

If limit is reached, varies off device and disables user profile.

QMAXSIGN The maximum number of incorrect sign-on attempts allowed. The valid values include:

QMCHPOOL The size of the machine storage pool (in kilobytes). The machine storage pool contains shared machine programs and licensed programs. The valid values include an integer in the range 256 through 2147483647.

QMAXACTLVL The maximum activity level of the system. This is the number of jobs that can compete at the same time for main storage and processor resources. The valid values include:

QPFRADJ Indicates whether the system should adjust values during IPL and adjust values dynamically for system pool sizes and activity levels. The valid values include:

*NONE

No performance adjustment.

*IPL

Performance adjustment at IPL.

*DYNAMIC

Performance adjustment at IPL and dynamically.

*IPLDYN

Dynamic performance adjustment.

QSRVDMP Specifies whether or not service dumps are created for unmonitored escape messages. You can also specify to create service dumps for system jobs and user jobs only. The valid values include:

*DMPALLJOB

Service dumps for unmonitored escape messages are created for all jobs.

*DMPSYSJOB

Service dumps for unmonitored escape messages are created only for system jobs, not user jobs.

*DMPUSRJOB

Service dumps for unmonitored escape messages are created only for user jobs and not system jobs. System jobs include the system arbiter, subsystem monitors, LU services process, spool readers and writers, and the start-control-program-function (SCPF) job.

*NONE

Service dumps are not done.

QSTRPRTWTR Specifies whether printer writers are started at IPL. The valid values include:

*YES

Start printer writers.

*NO

Do not start printer writers.

QSTRUPPGM The name of the startup program called from an autostart job when the controlling subsystem is started. The valid values include:

QTOTJOB The initial number of jobs for which auxiliary storage is allocated during IPL. The valid value is an integer in the range 1 through 32767.

QTSEPOOL The time-slice end pool. This value specifies whether interactive jobs should be moved to another main storage pool when they reach time-slice end. The valid values include:

*NONE

When time-sloe end is reached, jobs are not moved tot he base storage pool.

*BASE

When time-slice end is reached, jobs are moved to the base pool.
