Manual
CLASS_SCHEDULE DELETE
The DELETE subcommand deletes a scheduling class from the class
scheduler database file.
Format
CLASS_SCHEDULE DELETE class_name
Parameter
class_name
Specifies the name of the scheduling class. You must specify a class
name with the DELETE command. The maximum length for this name is 16
characters.
Qualifiers
None.
CLASS_SCHEDULE MODIFY
The MODIFY subcommand changes the characteristics of a scheduling class.
Format
CLASS_SCHEDULE MODIFY class_name
Parameter
class_name
Specifies the name of the scheduling class. You must specify a class
name with the MODIFY command. The maximum length for this name is 16
characters.
Qualifiers
/ACCOUNT
Specifies which user is part of this scheduling class. This is part of
a user's SYSUAF record.
The syntax for this qualifier is as follows:
[/ACCOUNT = (name1, name2,...name"n")]
|
/CPULIMIT
Defines the maximum amount of CPU time that this scheduling class can
receive for the specified days and hours.
The syntax for this qualifier is as follows:
/CPULIMIT = ([primary], [h1-h2=time%],[h1=time%],
[,...],[secondary],[h1-h2=time%],[h1=time%],[,...])
|
The h1-h2=time% syntax allows you to specify a range of hours followed
by the maximum amount of CPU time (expressed as a percentage) to be
associated with this set of hours. The first set of hours after the
keyword PRIMARY specifies hours on primary days; the set of hours after
the keyword SECONDARY specifies hours on secondary days. The hours are
inclusive; if you class schedule a given hour, access extends to the
end of that hour.
/PRIMEDAYS
Allows you to define which days are primary days and which days are
secondary days.
The syntax for this qualifier is as follows:
[/PRIMEDAYS = ([no]day[,...])]
|
You specify primary days as MON, TUE, WED, THU, FRI, SAT, and SUN. You
specify secondary days as NOMON, NOTUE, NOWED, NOTHU, NOFRI, NOSAT, and
NOSUN.
The default is MON through FRI and NOSAT and NOSUN. Any days omitted
from the list take their default value. You can use the DCL command,
SET DAY, to override the class definition of primary and secondary days.
/UIC
Specifies which users are part of this scheduling class. This is part
of a user's SYSUAF record.
The syntax for this qualifier is as follows:
[/UIC = (uic1,uic2,...uic"n")]
|
/USERNAME
Specifies which user is part of this scheduling class. This is part of
a user's SYSUAF record.
The syntax for this qualifier is as follows:
[/USERNAME = (name1, name2,...name"n")]
|
/WINDFALL
Specifies that all processes in the scheduling class are eligible for
windfall.
The syntax for this qualifier is as follows:
By enabling windfall, you allow processes in the scheduling class to
receive a "windfall," that is, a small percentage of CPU
time, when the class's allotted CPU time has been depleted and a CPU is
idle. Rather than let the CPU remain idle, you might decide that it is
better to let these processes execute, even if it means giving them
more than their alloted time.
The default value is for windfall to be disabled.
Description
To remove a time restriction, specify the time percentage as "none" for
the particular range of hours.
To remove a name or uic value, you must specify a minus sign in front
of each name or value.
CLASS_SCHEDULE RESUME
The RESUME subcommand complements the suspend command. You use this
command to resume a scheduling class that is currently suspended.
Format
CLASS_SCHEDULE RESUME class_name
Parameter
class_name
Specifies the name of the scheduling class. You must specify a class
name with the RESUME command. The maximum length for this name is 16
characters.
Qualifiers
None.
CLASS_SCHEDULE SHOW
The SHOW subcommand displays the characteristics of a scheduling class.
Format
CLASS_SCHEDULE SHOW [class_name] [/qualifier]
Parameter
class_name
Specifies the name of the scheduling class. You must specify a class
name or the /ALL qualifier with the SHOW command. The maximum length
for the class name is 16 characters.
Qualifiers
/ALL
Displays all scheduling classes. The qualifier must be specified if no
class name is given.
/FULL
Displays all information about this scheduling class.
Description
By default, a limited display of data is shown by the SHOW subcommand.
The default displays the following:
- Name
- Maximum CPU time or times for each range of hours
- Primary days and secondary days
- Windfall settings
CLASS_SCHEDULE SUSPEND
The SUSPEND subcommand suspends the specified scheduling class.
Format
CLASS_SCHEDULE SUSPEND class_name
Parameter
class_name
Specifies the name of the scheduling class. You must specify a class
name with the SUSPEND command. The maximum length for this name is 16
characters.
Qualifiers
None.
Description
When you suspend a scheduling class, all processes that are part of the
scheduling class remain as part of the class but are granted unlimited
CPU time.
CONFIGURATION SET CLUSTER_AUTHORIZATION
Modifies security data in a local area cluster.
Requires SYSPRV privilege.
Format
CONFIGURATION SET CLUSTER_AUTHORIZATION
Parameters
None.
Qualifiers
/GROUP_NUMBER=[n]
Specifies the cluster group number that is recorded in
SYS$SYSTEM:CLUSTER_AUTHORIZE.DAT. A group number uniquely identifies
each local area cluster on a single Ethernet. This number must be in
the range from 1 to 4095 or 61440 to 65535.
/PASSWORD=password
Specifies a password for cluster access. A password consists of 1 to 31
characters, including alphanumeric characters, dollar signs, and
underscores. A password provides a second level of validation to ensure
the integrity of individual clusters on the same Ethernet that
accidentally use identical group numbers. A password also prevents an
intruder who discovers the group number from joining the cluster.
Description
The CONFIGURATION SET CLUSTER_AUTHORIZATION command modifies the group
number and password of a local area cluster, as recorded in
SYS$SYSTEM:CLUSTER_AUTHORIZE.DAT. If your configuration has multiple
system disks, SYSMAN automatically updates each copy of
CLUSTER_AUTHORIZE.DAT, provided the environment is defined as a cluster
(SET ENVIRONMENT/CLUSTER). For more information about
CLUSTER_AUTHORIZE.DAT, see HP OpenVMS Cluster Systems.
Caution
If you change either the group number or the password, you must reboot
the entire cluster.
|
The file CLUSTER_AUTHORIZE.DAT is initialized during execution of
CLUSTER_CONFIG.COM and maintained through SYSMAN. Under normal
conditions, altering records in the CLUSTER_AUTHORIZE.DAT file
interactively is not necessary. To protect the integrity of the cluster
membership use the CONFIGURATION SET CLUSTER_AUTHORIZATION command.
Example
|
SYSMAN> SET ENVIRONMENT/CLUSTER/NODE=NODE21
SYSMAN> SET PROFILE /PRIVILEGES=SYSPRV
SYSMAN> CONFIGURATION SET CLUSTER_AUTHORIZATION/PASSWORD=GILLIAN
%SYSMAN-I-CAFOLDGROUP, existing group will not be changed
%SYSMAN-I-GRPNOCHG, Group number not changed
SYSMAN-I-CAFREBOOT, cluster authorization file updated.
The entire cluster should be rebooted.
|
The CONFIGURATION SET CLUSTER_AUTHORIZATION command in this example
sequence modifies the cluster password. Note that the environment is
defined to be a cluster, and the SYSPRV privilege is established before
entering the CONFIGURATION SET CLUSTER_AUTHORIZATION command.
CONFIGURATION SET TIME
Modifies the current system time.
Requires OPER, LOG_IO, and SYSPRV privileges, and, in a cluster
environment, SYSLCK privilege.
Format
CONFIGURATION SET TIME [time]
Parameters
None.
Qualifiers
None.
Description
The CONFIGURATION SET TIME command enables you to reset the system
time. Specify a time value using the following format:
[dd-mmm-yyyy[:]] [hh:mm:ss.cc]
|
You can also enter a delta time value. For more information about time
formats, see the OpenVMS User's Manual.
In an environment of individual nodes, SYSMAN sets the time to the
specified value on each node. Without a time specification, SYSMAN sets
the time according to the time-of-year clock on each node.
In an OpenVMS Cluster environment, SYSMAN sets the time to the
specified value on each node. If you do not specify a value, SYSMAN
uses the time-of-year clock. In a local cluster, SYSMAN reads the clock
on the node from which you are executing SYSMAN and assigns this value
to all nodes in the cluster. In a remote OpenVMS Cluster, SYSMAN reads
the clock on the target node in the cluster and assigns that value to
all nodes. Note that the time-of-year clock is optional for some
processors; for more information, see your processor handbook.
SYSMAN uses special processing in an OpenVMS Cluster environment to
ensure that all processors in the cluster are set to the same time.
Because of communication and processing delays, it is not possible to
synchronize clocks exactly. However, the variation is typically less
than a few hundredths of a second. If SYSMAN cannot set the time to
within one half second of the specified time, you receive a warning
message that names the node that failed to respond quickly enough.
As a result of slight inaccuracies in each processor clock, times on
various members of a cluster tend to drift apart. The following
procedure synchronizes system times in a cluster environment:
$ SYNCH_CLOCKS:
$ RUN SYS$SYSTEM:SYSMAN
SET ENVIRONMENT/CLUSTER
CONFIGURATION SET TIME
EXIT
$ WAIT 6:00:00
$ GOTO SYNCH_CLOCKS
|
The procedure sets the time on all cluster nodes to the value obtained
from the local time-of-year clock, waits 6 hours, then resets the time
for the cluster.
Example
|
SYSMAN> SET ENVIRONMENT/NODE=(NODE21,NODE22,NODE23)
SYSMAN> SET PROFILE /PRIVILEGE=LOG_IO
SYSMAN> CONFIGURATION SET TIME 12:38:00
|
The CONFIGURATION SET TIME command in this example sequence modifies
the system time on NODE21, NODE22, and NODE23.
CONFIGURATION SHOW CLUSTER_AUTHORIZATION
Displays the group number and multicast address of a local area cluster.
Requires SYSPRV privilege.
Format
CONFIGURATION SHOW CLUSTER_AUTHORIZATION
Parameters
None.
Qualifier
/OUTPUT[=filespec]
Redirects output from SYS$OUTPUT to the specified file. If no file
specification is provided, SYSMAN writes the output to SYSMAN.LIS in
the current directory.
Description
The CONFIGURATION SHOW CLUSTER_AUTHORIZATION command displays the group
number and multicast address, and Ethernet address used to send a
message to all nodes in the cluster. The group number and multicast
address are recorded in SYS$SYSTEM:CLUSTER_AUTHORIZE.DAT during the
CLUSTER_CONFIG dialog.
In a cluster or multinode environment, SYSMAN displays the group number
of the first node and then displays the names of any nodes in the
cluster whose group numbers, passwords, or both, are different.
Example
|
SYSMAN> SET ENVIRONMENT/CLUSTER/NODE=NODE21
.
.
.
SYSMAN> SET PROFILE /PRIVILEGE=SYSPRV
SYSMAN> CONFIGURATION SHOW CLUSTER_AUTHORIZATION
Node NODE23: Cluster group number 65240
Multicast address: AB-00-04-01-F2-FF
|
The CONFIGURATION SHOW CLUSTER_AUTHORIZATION command in this example
displays the group number and multicast address of NODE21. Because the
group number and password on other nodes in the cluster are identical,
no further information is displayed.
CONFIGURATION SHOW TIME
Displays the current date and system time to the nearest hundredth of a
second.
Format
CONFIGURATION SHOW TIME
Parameters
None.
Qualifier
/OUTPUT[=filespec]
Redirects output from SYS$OUTPUT to the specified file. If no file
specification is provided, SYSMAN writes the output to SYSMAN.LIS in
the current directory.
Example
|
SYSMAN> SET ENVIRONMENT/CLUSTER/NODE=NODE21
.
.
.
SYSMAN> CONFIGURATION SHOW TIME
System time on node NODE21: 19-JUN-2002 13:32:19.45
System time on node NODE22: 19-JUN-2002 13:32:27.79
System time on node NODE23: 19-JUN-2002 13:32:58.66
|
The CONFIGURATION SHOW TIME command in this example displays the system
times for all nodes in the cluster.
DEFINE/KEY
Defines a key to execute a SYSMAN command. This enables you to press
the key to enter a command, instead of typing the command name.
Format

string
Specifies the string you want entered when you press the defined key.
For example, you can define string as the SYSMAN command SHOW
ENVIRONMENT or SHOW PROFILE.
Qualifiers
/ECHO (default)
/NOECHO
Specifies whether the command line echoes after you press the defined
key. Note that you cannot define a key using both the /NOECHO and
/NOTERMINATE qualifiers.
/IF_STATE=state_list
/NOIF_STATE
Specifies a list of states, any one of which must be set in order to
enable the specified key definition. If you omit or negate this
qualifier, the current state prevails.
/LOCK_STATE
/NOLOCK_STATE (default)
Retains the state specified by the /SET_STATE qualifier until you use
the /SET_STATE qualifier again to change it.
/SET_STATE
/NOSET_STATE
Associates a state with the key you are defining. A state name can be
any alphanumeric string. If you omit or negate this qualifier, the
current state remains unchanged. You cannot define a key using both the
/SET_STATE and /TERMINATE qualifiers.
/TERMINATE
/NOTERMINATE
Determines whether the specified command string executes when you press
the key. When you use /NOTERMINATE, you must press the Return key to
execute the command string. You cannot define a key using both the
/SET_STATE and /TERMINATE qualifiers.
Description
The DEFINE/KEY command assigns a key to a SYSMAN command. This enables
you to execute the command by pressing the key. You can confirm which
keys you have defined by using the SHOW KEY command.
When you exit from SYSMAN, any SYSMAN key definitions you established
will be lost unless you define them in a SYSMAN initialization file.
(See Section 24.1.2.)
Examples
| #1 |
SYSMAN> DEFINE /KEY PF1 "SHOW PROFILE"
|
This example shows how to define the keypad key PF1 as the SYSMAN
command SHOW PROFILE. To execute the SHOW PROFILE command, press PF1
and then the Return key.
| #2 |
SYSMAN> DEFINE /KEY KP0 /TERMINATE "CONFIGURATION SHOW TIME"
|
This example shows how to define the keypad key 0 as the CONFIGURATION
SHOW TIME command. The /TERMINATE qualifier causes the SYSMAN command
to execute when you press keypad key 0 without having to press Return.
DISKQUOTA ADD
Adds an entry to a disk quota file and initializes the usage count to
zero.
Requires write (W) access to the quota file.
Format
DISKQUOTA ADD owner
Parameter
owner
Specifies the user identification code (UIC) or rights identifier for
which the quota entry is added. You can specify the UIC in numeric or
alphanumeric format. For complete information about UIC specification,
see the HP OpenVMS Guide to System Security.
Rights identifiers are granted with the Authorize utility and use an ID
format rather than a UIC format. For a complete description of rights
identifiers, see the HP OpenVMS Programming Concepts Manual.
When working in nonlocal environments, be careful that the alphanumeric
UIC or rights identifiers that you use are valid for the environment.
Qualifiers
/DEVICE=device-spec
Specifies the location of the quota file. SYSMAN validates the device
specification. You can specify a logical name for device-spec.
If you do, the logical name is translated in the target environment.
Without a device specification, SYSMAN uses the default disk on the
target node. Unless you have set a default device with the SET PROFILE
command, the default disk is the current device on the local node or
the login default device on another node, depending on the established
environment.
/OVERDRAFT=value
Specifies a positive integer that provides an overdraft value for the
specified UIC. If omitted, the overdraft value defaults to the
overdraft value in the entry for [0,0].
/PERMQUOTA=value
Specifies a positive integer that provides the quota for the specified
UIC. If omitted, the permanent quota defaults to the value of the quota
in the entry for [0,0].
Description
The DISKQUOTA ADD command appends individual entries to a quota file on
the specified disk. Note that the quota file must already exist and be
enabled.
Unless you specify the permanent quota and overdraft values, SYSMAN
applies the default values from the UIC entry [0,0]. You adjust UIC
[0,0] with the DISKQUOTA MODIFY command.
Example
|
SYSMAN> SET ENVIRONMENT/NODE=(NODE22,NODE21) (1)
%SYSMAN-I-ENV, Current command environment:
Individual nodes: NODE22,NODE21
Username ALEXIS will be used on nonlocal nodes.
SYSMAN> SET PROFILE /PRIVILEGE=SYSPRV (2)
SYSMAN> DISKQUOTA ADD [MKT,MORSE] /DEVICE=WORK1 -
_SYSMAN> /PERMQUOTA=200 /OVERDRAFT=50 (3)
SYSMAN> DISKQUOTA ADD PAYROLL /DEVICE=WORK1 /PERMQUOTA=1000 (4)
