System value (SYSVAL)

Specifies the name of the system value that is displayed.
This is a required parameter.
The system values are:
QABNORMSW

Previous end of system indicator. This value cannot be changed.

'0' means previous end was normal.
'1' means previous end was abnormal.

QACGLVL

Accounting level. Changes made to this system value take effect for jobs started after the change is made.

*NONE - No accounting information is written to a journal.
*JOB - Job resource use is written to a journal.
*PRINT - Spooled and printer file resource use is written to a journal.

QACTJOB

QADLTOTJ

Additional total number of jobs for which storage is allocated. Changes made to this system value take effect immediately.

QALWJOBITP

Allow jobs to be interrupted. This system value specifies how the system responds to user initiated requests to interrupt a job to run a user-defined exit program in that job. The Call Job Interrupt Program (QWCJBITP) API in the iSeries Information Center contains information on using job interrupt exit programs. The Change Job Interrupt Status (QWCCJITP) API in the iSeries Information Center contains information on retrieving and changing the interrupt status of a job. The interrupt status of an active job can be changed at any time but will only take effect when the value of QALWJOBITP allows jobs to be interrupted. Changes made to this system value take effect immediately. The shipped value is 0.

0 means the system will not allow jobs to be interrupted to run user-defined exit programs. All new jobs becoming active will default to be uninterruptible. All active jobs are uninterruptible regardless of what the job interrupt status is set to.
1 means the system will allow jobs to be interrupted to run user-defined exit programs. All new jobs becoming active will default to be uninterruptible.
2 means the system will allow jobs to be interrupted to run user-defined exit programs. All new jobs becoming active will default to be interruptible.

This value can be changed to the name of a program, which will be called when the user presses the Attn key in a job where ATNPGM(*SYSVAL) is specified in the user profile. Changes made to this system value take effect immediately.

QAUDCTL

Audit control. This system value contains the on and off switches for object and user action auditing. This system value activates auditing on the system that is selected by the Change Object Auditing (CHGOBJAUD) and Change User Auditing (CHGUSRAUD) commands and the QAUDLVL and QAUDLVL2 system values. Changes made to this system value take effect immediately.

*NOTAVL - The user performing the command is not allowed to display the current auditing value. You cannot change the system value to not available (*NOTAVL).
*NONE - No security auditing is done on the system. This is the shipped value.
*AUDLVL - The actions specified in the QAUDLVL and QAUDLVL2 system values will be logged to the security journal. Also actions specified by a user profile's action auditing values will be audited. A user profile's action auditing values are set through the AUDLVL parameter on the CHGUSRAUD command.
*OBJAUD - Actions against objects that have an object audit value other than *NONE will be audited. An object's audit value is set through the Change Auditing Value (CHGAUD) command or the CHGOBJAUD command.
*NOQTEMP - No auditing of most objects in QTEMP is done. You must specify *NOQTEMP with either *OBJAUD or *AUDLVL. You can not specify *NOQTEMP by itself.

QAUDENDACN

Audit journal error action. This system value specifies the action to be taken by the system if errors occur when an audit journal entry is being sent by the operating system to the security audit journal. Changes made to this system value take effect immediately.

*NOTAVL - The user performing the command is not allowed to display the current auditing value. You cannot change the system value to not available (*NOTAVL).
*NOTIFY - Notification of failure is sent to the QSYSOPR and QSYSMSG message queues, and then the action that caused the audit attempt continues.
*PWRDWNSYS - The Power Down System (PWRDWNSYS) command is issued. The system will then be brought up in a restricted state on the following IPL, and then only a user with audit (*AUDIT) and all object (*ALLOBJ) special authority can sign on the system.

QAUDFRCLVL

Force audit journal. This system value specifies the number of audit journal entries that can be written to the security auditing journal before the journal entry data is forced to auxiliary storage.

1 through 100.
*SYS - The system determines when the journal entries are to be written to auxiliary storage based on internal system processing. *SYS cannot be returned in a decimal variable, so the command returns 0 when the value *SYS is specified.
*NOTAVL - The user performing the command is not allowed to display the current auditing value. You cannot change the system value to not available (*NOTAVL). *NOTAVL cannot be returned in a decimal variable, so the command returns -1 in place of *NOTAVL.

Changes made to this system value take effect immediately.

1 means the dynamic priority scheduler is on.

QENDJOBLMT

Maximum time (in seconds) for application clean up during immediate ending of a job.
When a job being ended has a signal handling procedure for the asynchronous signal SIGTERM, the SIGTERM signal is generated for that job. When the signal handling procedure for the SIGTERM signal is given control, the procedure can take the appropriate actions to avoid undesirable results such as application data that has been partially updated. If the SIGTERM signal handler has not completed in the specified time, the system ends the job.
When the job is ended in a controlled manner, the maximum time for the SIGTERM signal handler is specified on the command. When the job is ended in an immediate manner, the maximum time for the SIGTERM signal handler is specified by this system value. This time limit is used when ending one job, when ending all the jobs in a subsystem, or when ending all jobs in all subsystems. After two minutes, the system operator can use the End Job (ENDJOB) command with OPTION(*IMMED) to override the QENDJOBLMT value and end individual jobs immediately.
A change to this value takes effect immediately. Jobs that are already ending are not affected.

QFRCCVNRST

Force conversion on restore. This system value allows you to specify whether or not to convert programs, service programs, SQL packages, and module objects during the restore. It can also prevent some objects from being restored. The default value on the restore commands use the value of this system value. Changes to this system value will take effect immediately.

0

Do not convert anything. Do not prevent anything from being restored.

1

Objects with validation errors will be converted.

2

Objects requiring conversion to be used on the current version of the operating system and objects with validation errors will be converted.

3

Objects suspected of having been tampered with, objects containing validation errors, and objects requiring conversion to be used by the current version of the operating system will be converted.

4

Objects that contain sufficient creation data to be converted and do not have valid digital signatures will be converted. An object that does not contain sufficient creation data will be restored without conversion. NOTE: Objects (signed and unsigned) that have validation errors, are suspected of having been tampered with, or require conversion to be used by the current version of the operating system, but cannot be converted will not be restored.

5

Objects that contain sufficient creation data will be converted. An object that does not contain sufficient creation data will be restored. NOTE: Objects that have validation errors, are suspected of having been tampered with, or require conversion to be used on the current version of the operating system, but cannot be converted will not be restored.

6

All objects that do not have a valid digital signature will be converted. NOTE: An object with a valid digital signature that also has a validation error, is suspected of having been tampered with, or requires conversion to be used on the current version of the operating system, but cannot be converted will not be restored.

7

Every object will be converted.

When an object is converted, its digital signature is discarded. The state of the converted object is set to user state. After conversion, objects will have a good validation value and are not suspected of having been tampered with.

QHOUR

Hour of the day. Changes made to this system value take effect immediately.

QIGCFNTSIZ

Double byte coded font point size. Used along with the system value, QIGCCDEFNT, double byte coded font. They will be used when transforming SNA character string (SCS) into an Advanced Function Printing Data Stream (AFPDS) and when creating an AFPDS spooled file with shift in/ shift out (SI/SO) characters present in the data.

*NONE means that no point size is identified to the system. The point size is selected by the system based on the type of printer used.
000.1 - 999.9 means the point size for the double byte coded font.

QINACTITV

Inactive interactive job time out interval in minutes. When the time interval is changed to a value other than *NONE a new inactivity interval is established and the analysis of job inactivity is started again. The system value QINACTMSGQ determines the action the system takes. For information on enforcement for target pass-through and TELNET sessions, see the Work Management information in the iSeries Information Center at http://www.ibm.com/eserver/iseries/infocenter
Local jobs that are currently signed on to a remote system are excluded. For example, a work station is directly attached to system A, and system A has QINACTIV set on. If Display Station Pass-through or TELNET is used to sign on to system B, this work station is not affected by the QINACTITV value set on system A. Changes made to this system value take effect immediately.

*NONE means that the system does not check for inactivity.
5 - 300 means the number of minutes a job can be inactive before action is taken.

QINACTMSGQ

The qualified name of a message queue to which job inactive messages will be sent if QINACTMSGQ is not *NONE. The message queue must exist before the system value can be changed to a message queue name. Both an object name and library name can be specified. Changes made to this system value take effect immediately.

*ENDJOB means that interactive jobs, secondary jobs, and group jobs will be ended.
*DSCJOB means that interactive jobs, secondary jobs, and group jobs will be disconnected.
Message queue name is the name of a message queue that receives a message when a job has been inactive.

QIPLDATTIM
Date and time for automatic IPL. This system value can be set independently in each partition. If the primary partition is powered down at the time an automatic IPL should occur in a secondary partition, the IPL will not occur.

QTIMADJ

Time adjustment. This system value can be used to identify software that adjusts the system clock to keep it synchronized with an external time source. This value should be maintained by time adjustment software and is intended as an aid to prevent having multiple time adjustment applications conflict with each other. There are no checks performed by the system to verify this value or that software is or is not performing time adjustments. IBM time adjustment offerings will use identifiers that start with QIBM such as 'QIBM_OS400_SNTP'. Other software suppliers should follow a similar naming convention of company name and product name.
Time adjustment software should check QTIMADJ prior to starting. If QTIMADJ has an identifier for other time adjustment software, then the software being started should notify the user of this potential conflict and confirm that this time adjustment software should be started. When QTIMADJ is *NONE the software should update QTIMADJ to identify that it is now responsible for adjusting the system clock. Time adjustment software should check QTIMADJ again prior to ending. QTIMADJ should be set to *NONE only if the current value identifies this time adjustment software that is ending. Changes made to this system value take effect immediately. The shipped value is *NONE.

1-99999 means specify the delay time in seconds before the system powers down.

On some partitioned systems, this system value can only be changed from the primary partition.
For more information on partitions, see the Logical Partitions topic in the iSeries Information Center at http://www.ibm.com/eserver/iseries/infocenter.

QUPSMSGQ

Message queue for uninterruptible power supply messages. Changes made to this system value take effect the next time there is a power failure.

QUSEADPAUT

Defines which users can create, change and update programs and service programs with the (use adopted authority) USEADPAUT(*YES) attribute. When a program or service program has a use adopted authority attribute of *YES, the program/service program can use any adopted authority that is being passed to it from a program/ service program higher in the call stack.
This system value has no effect on the following:

Existing programs/service programs created with the USEADPAUT(*YES) attribute. Users are responsible for deciding which existing programs/service programs should be changed to have USEADPAUT(*NO).
Restoring a program/service program that uses adopted authority. These program/service programs can still be restored on your system.
Duplicating a program/service program that uses adopted authority. The USEADPAUT attribute of the existing program/service program is copied to the new object.

The following values can be specified:

*NONE means there is no restriction on who can create, change or update a program/service program to use adopted authority. Any user can create, change or update a program/service program to have the USEADPTAUT(*YES) attribute.
Name means you can specify the name of the authorization list which will control which users can set the USEADPAUT(*YES) attribute. The user needs *USE authority to the authorization list to be able to create, change or update programs/service programs with the USEADPAUT(*YES) attribute. Authority to the authorization list cannot come from adopted authority. That is, if you are running a program that adopts authority, the adopted authority is not used when checking authority to the authorization list.

QUSRLIBL

User part of the library list. Changes made to this system value take effect for jobs started after the change is made.

QUTCOFFSET

Indicates the number of hours (in 24-hour format) and minutes that the current system time is offset from the Coordinated Universal Time (UTC).

+hhmm means that the current system time is hh hours and mm minutes ahead of UTC.
-hhmm means that the current system time is hh hours and mm minutes behind UTC.

This system value must be the same as the offset that is associated with the time zone description specified in the system value QTIMZON. A change to a different time zone description for QTIMZON may result in a different associated offset. The system value QUTCOFFSET will be changed as well to match this new offset. QUTCOFFSET cannot be changed to a value that is different than the offset currently associated with QTIMZON. If an attempt is made to do so, the diagnostic message CPD1687 will be issued.

QVFYOBJRST

Verify object on restore. This system value specifies the policy to be used for object signature verification during a restore operation. This value applies to objects of types: *CMD, *PGM, *SRVPGM, *SQLPKG and *MODULE. It also applies to *STMF objects which contain Java programs. This value also specifies the policy for PTFs applied to the system including Licensed Internal Code fixes. Changes made to this system value take effect immediately. See Verify object on restore for additional information.

QYEAR

Year. Changes made to this system value take effect immediately.
