Manual
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, refer to 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.
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. Refer to the OpenVMS User's Manual for
more information about time formats.
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; refer to your processor handbook for further information.
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-2000 13:32:19.45
System time on node NODE22: 19-JUN-2000 13:32:27.79
System time on node NODE23: 19-JUN-2000 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
DEFINE/KEY key-name string
Parameters

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 21.1.2.)
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,
refer to the OpenVMS Guide to System Security.
Rights identifiers are granted with the Authorize utility and use an ID
format rather than a UIC format. Refer to the OpenVMS Programming Concepts Manual for a
complete description of rights identifiers.
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 - (3)
_SYSMAN> /PERMQUOTA=200 /OVERDRAFT=50
SYSMAN> DISKQUOTA ADD PAYROLL /DEVICE=WORK1 /PERMQUOTA=1000 (4)
|
- Defines the management environment to be
NODE22 and NODE21.
- Adds SYSPRV privilege to the user's current
privileges in order to write to the quota file.
- Adds UIC [MKT,MORSE] to the quota file on the
device named WORK1 on both NODE22 and NODE21, setting the permanent
quota to 200 disk blocks and the overdraft limit to 50 disk blocks, for
an absolute limit of 250 blocks.
If the user name MORSE has a
unique UIC on the system, you can enter the following command:
SYSMAN> DISKQUOTA ADD MORSE
|
- Adds an entry for the rights identifier
PAYROLL. Any user holding the PAYROLL identifier can use this disk
space.
DISKQUOTA CREATE
Creates and enables a quota file for a disk volume that does not
currently contain one.
Requires write (W) access to the volume's master file directory (MFD),
plus one of the following items: SYSPRV privilege, a system UIC, or
ownership of the volume.
Format
DISKQUOTA CREATE
Parameters
None.
Qualifier
/DEVICE=device-spec
Specifies the disk volume on which to create a quota file. SYSMAN
validates the device specification. A logical name may be specified for
device-spec. If so, it 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.
Description
The DISKQUOTA CREATE command creates a quota file for a volume that
does not currently have one.
Only one quota file, [000000]QUOTA.SYS, can be present on any volume or
volume set. As soon as you create a quota file, establish default
values for quotas and overdrafts by adjusting UIC [0,0] with the
DISKQUOTA MODIFY command. When a disk has existing files, use the
DISKQUOTA REBUILD command to have SYSMAN update the quota file to
contain current usage values.
Note
Compaq recommends that you do not create and enable a quota file on the
system disk unless users are allowed to create files on that disk.
|
Example
|
SYSMAN> SHOW ENVIRONMENT
%SYSMAN-I-ENV, Current command environment:
Node NODE24 of local cluster
Username ALEXIS will be used on nonlocal nodes
SYSMAN> DO SHOW DEVICES
.
.
.
SYSMAN> DISKQUOTA CREATE /DEVICE=DJA31:
SYSMAN> DISKQUOTA MODIFY /DEVICE=DJA31: [0,0] -
_SYSMAN> /PERMQUOTA=10000 /OVERDRAFT=100
|
The commands in this example sequence display the characteristics of
the current management environment and verify the device name. Then
they create a quota file on the disk DJA31 and set up default quota
values.
