The DELETE subcommand deletes a scheduling class from the class scheduler database file.
CLASS_SCHEDULE DELETE class_name
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.
None.
The MODIFY subcommand changes the characteristics of a scheduling class.
CLASS_SCHEDULE MODIFY class_name
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.
/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:
[/WINDFALL])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.
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.
The RESUME subcommand complements the suspend command. You use this command to resume a scheduling class that is currently suspended.
CLASS_SCHEDULE RESUME class_name
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.
None.
The SHOW subcommand displays the characteristics of a scheduling class.
CLASS_SCHEDULE SHOW [class_name] [/qualifier]
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.
/ALL
Displays all scheduling classes. The qualifier must be specified if no class name is given./FULL
Displays all information about this scheduling class.
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
The SUSPEND subcommand suspends the specified scheduling class.
CLASS_SCHEDULE SUSPEND class_name
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.
None.
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.
Modifies security data in a local area cluster.Requires SYSPRV privilege.
CONFIGURATION SET CLUSTER_AUTHORIZATION
None.
/GROUP_NUMBER=[n]
Specifies the cluster group number that is recorded in SYS$SYSTEM:CLUSTER_AUTHORIZE.DAT. A group number uniquely identifies each local area cluster on a single Ethernet. This number must be in the range from 1 to 4095 or 61440 to 65535./PASSWORD=password
Specifies a password for cluster access. A password consists of 1 to 31 characters, including alphanumeric characters, dollar signs, and underscores. A password provides a second level of validation to ensure the integrity of individual clusters on the same Ethernet that accidentally use identical group numbers. A password also prevents an intruder who discovers the group number from joining the cluster.
The CONFIGURATION SET CLUSTER_AUTHORIZATION command modifies the group number and password of a local area cluster, as recorded in SYS$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.
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.
Modifies the current system time.Requires OPER, LOG_IO, and SYSPRV privileges, and, in a cluster environment, SYSLCK privilege.
CONFIGURATION SET TIME [time]
None.
None.
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_CLOCKSThe 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.
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.
Displays the group number and multicast address of a local area cluster.Requires SYSPRV privilege.
CONFIGURATION SHOW CLUSTER_AUTHORIZATION
None.
/OUTPUT[=filespec]
Redirects output from SYS$OUTPUT to the specified file. If no file specification is provided, SYSMAN writes the output to SYSMAN.LIS in the current directory.
The CONFIGURATION SHOW CLUSTER_AUTHORIZATION command displays the group number and multicast address, and Ethernet address used to send a message to all nodes in the cluster. The group number and multicast address are recorded in SYS$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.
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.
Displays the current date and system time to the nearest hundredth of a second.
CONFIGURATION SHOW TIME
None.
/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.
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.
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.
DEFINE/KEY key-name string
key-name
Specifies the name of the key you are defining. Use the key names in the following table when defining keys:
Key Name VT100 LK201/LK401 PF1 PF1 PF1 PF2 PF2 PF2 PF3 PF3 PF3 PF4 PF4 PF4 KP0, KP1--KP9 keypad 0--9 keypad 0--9 PERIOD period key period key COMMA comma key comma key MINUS minus key minus key ENTER ENTER key ENTER key UP, DOWN, LEFT, RIGHT arrow keys arrow keys FIND, INSERT_HERE -- Find, Insert Here keys REMOVE, SELECT -- Remove, Select keys PREV_SCREEN -- Previous Screen key NEXT_SCREEN -- Next Screen key HELP, DO -- Help, Do keys F6--F10, F11--F14 -- function keys F17--F20 -- function keys 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.
/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.
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.)
| #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.
Adds an entry to a disk quota file and initializes the usage count to zero.Requires write (W) access to the quota file.
DISKQUOTA ADD owner
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.
/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].
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.
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.
