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:
*NOMAX (There is no maximum number of sign-on attempts.)
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:
*NOMAX (There is no maximum level for the system.)
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:
*NONE or a value with these characteristics
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. |
