SCF Reference Manual for the Kernel Subsystem

For considerations regarding the configuration of OSS persistent processes, see “Considerations
for OSS Persistent Processes” (page 83) and the Open System Services Management and Operations
Guide.
ALTER PROCESS Example
This example alters a generic process to run in processor 4 instead of processor 3:
-> ALTER PROCESS $ZZKRN.MY-OWN-PROCESS, CPU 4
ALTER SUBSYS Command
Use the ALTER SUBSYS command to change one or more system attributes of the Kernel subsystem.
ALTER [ / OUT file-spec / ]
SUBSYS $ZZKRN[ , attribute-spec ]...
SUBSYS $ZZKRN
is the name of the Kernel subsystem manager process. You can omit SUBSYS and $ZZKRN if
you have specified them with an ASSUME command.
attribute-spec
identifies the attribute names and values for the object specified in the command. The attributes
are:
DAYLIGHT_SAVING_TIME { TABLE | USA66 | NONE }
DESTINATION_CONTROL_TABLE { SMALL | MEDIUM }
POWERFAIL_DELAY_TIME { n | RIDETHRUONLY }
RESIDENT_TEMPLATES [[$SYSTEM.]subvol.]filename
SYSTEM_NAME \sysname
SYSTEM_NUMBER n
TIME_ZONE_OFFSET [ + | - ] [h]h[:mm]
TNSMISALIGN { FAIL | NOROUND }
NONRESIDENT_TEMPLATES [[$SYSTEM.]subvol.]filename
TLE_LIMIT n
AUTO_RETRY_ON_ERROR_654 { OFF | ON }
DAYLIGHT_SAVING_TIME { TABLE | USA66 | NONE }
specifies the daylight-saving time algorithm to be used when the system clock is set.
See also the procedure “Changing the System Name or System Number (H-Series RVUs)”
(page 30). Changes to this attribute take effect at the next Manual Reload or Hard Reset of
the system.
TABLE
specifies that a table of DST (daylight-saving time) transitions is to be loaded at system-load
time. To initialize the DST transitions, you use either the ADDDSTTRANSITION command
(documented in the TACL Reference Manual) or the ADDDSTTRANSITION procedure
(documented in the Guardian Procedure Calls Reference Manual).
You also must initialize the DST table with at least one DST transition that is less than the
current date and time, and at least two DST transitions that are greater than the current
date and time before the SETTIME command is entered. For considerations related to use
of a DST table, see the Guardian Procedure Calls Reference Manual.
USA66
specifies that your location follows the rules set by the United States by the Uniform Time
Act of 1966 for daylight-saving time. In the United States, starting from the year 2007,
DST begins at 2:00 AM on the second Sunday in March, when clocks are advanced by
one hour; DST ends at 2:00 AM on the first Sunday in November, when clocks are set
back by one hour.
