What's new for V5R4

With each release, you are able to increase the functionality of your system values by using the enhancements to the existing system values and the new system values.

New commands for Save System Information (SAVSYSINF) and Restore System Information (RSTSYSINF)

You can use the SAVSYSINF command to save system values and network attributes rather than having to save the entire system (SAVSYS) each time. You can use the RSTSYSINF command to restore system values and network attributes. You cannot use the RSTSYSINF command while the SAVSYSINF command is running, and it can only be performed within the same operating system release or when restoring a later release. There are special considerations to take into account, regarding system values and the usage of the new save and restore commands, SAVSYSINF and RSTSYSINF. See Save system information for more information about these considerations.

New and changed system values

Several system values are either new or changed for V5R4. To identify the system value changes for V5R4, see the following table:

New system values
Allow jobs to be interrupted to run user-defined exit programs	QALWJOBITP	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.
Produce printer output for job log	QLOGOUTPUT	This system value specifies how the job log will be produced when a job completes.
Changed system values
Activate action auditing	QAUDLVL and QAUDLVL2	A new special value has been added for Attention events (*ATNEVT). Attention events are conditions that require further evaluation to determine the conditions security significance.
Maximum job log size	QJOBMSGQMX	The lower limit on this system value has changed from 8MB to 2MB. The new range is now 2 to 64 MB.
History log file size	QHSTLOGSIZ	The valid range of records has changed from 1 to 65535 to 1 to 10,000,000. There is now also a new value, Daily (*DAILY), which enables you to create a new version of the history log each day.
Locale	QLOCALE	For new systems, or systems that have been completely reinstalled, the initial setting for this value will be a default locale based on the primary NLV installed. For NLV's that do not have a matching locale, the default setting in iSeries™ Navigator is now EN_US while the default value on the character-based interface is /QSYS.LIB/EN_US.LOCALE.
Log software problems detected by the system	QSFWERRLOG	When a software error is detected by the system, the error is evaluated to determine if it should be logged unconditionally, or if the decision to log the error should be deferred to the policy-based Service Monitor.
