Requests that SYSMAN read subsequent command input from the specific file or device.

Format

@ filespec

Parameter

filespec

Specifies either the input device or the command procedure you want to execute. The default file type is .COM. You cannot use wildcard characters in the file specification.

Description

Use the execute procedure command to execute a command procedure containing SYSMAN commands. To execute the command procedure, invoke SYSMAN, place the at sign (@) command at the beginning of a command line, then specify the file name of the command procedure.

The command procedure can contain any valid SYSMAN command.

Examples

$ CREATE ENV.COM 
SET ENVIRONMENT 
SHOW PROFILE[Ctrl/Z]
$ RUN SYS$SYSTEM:SYSMAN 
SYSMAN> @ENV.COM
 
%SYSMAN-I-DEFDIR, default directory on node -- SYS$SYSROOT:[SYSMGR] 
%SYSMAN-I-DEFPRIV, default process privileges on node -- 
        CMKRNL 
        CMEXEC 
        SYSNAM 
        .
        .
        .
        GRPPRV 
        READALL 
        SECURITY 
SYSMAN>
      

This example shows how to create a command procedure that sets the SYSMAN environment to the local node, and displays the current profile. These commands execute when you enter the @ENV.COM command.

$ CREATE TIME.COM 
SET ENVIRONMENT/CLUSTER 
CONFIGURATION SHOW TIME[Ctrl/Z] 
$ RUN SYS$SYSTEM:SYSMAN 
SYSMAN> @TIME 
 
System time on node NODE23: 19-JUN-2000 13:32:19.45
System time on node NODE24: 19-JUN-2000 13:32:27.79
System time on node NODE25: 19-JUN-2000 13:32:58.66
      

This example shows how to create and execute a command procedure that shows the current date and time for all the nodes in the cluster.

Adds a new record to the automatic login facility (ALF) database. You can also create records for proxy accounts.

Requires read (R) and write (W) access to the SYSALF database (SYS$SYSTEM:SYSALF.DAT by default).

Format

ALF ADD device user

Parameters

device

Specifies the terminal name or port name that you want to assign to a user name. The parameter device must be a terminal name if you do not specify qualifiers on the command line, and can be either a logical name or an abbreviated device name. This parameter accepts a maximum of 63 characters, including devices for proxy accounts.

user

Specifies the user name of the account that you want to assign to a particular terminal or port.

Qualifiers

/TERMINAL (default)

Checks whether the device name you specified is a terminal on the target system. The parameter device can be a logical name or an abbreviated device name, which SYSMAN translates to a full device name.

/PORT

Checks whether the device name you specified is a valid port. If the port name contains special characters, such as a slash (/), or if it contains lowercase letters that you want to preserve, you must enclose the port name within quotation marks (" ").

Be aware that anything within quotation marks is written literally to the ALF database file. For example, if the actual port name contains uppercase letters as well as special characters, be sure to specify uppercase letters within the quotation marks. Otherwise, a mismatch will occur between the actual port name and what is specified in the SYSALF.DAT file.

/PROXY

Checks that the device name is in the NODE::USERNAME format.

/LOG

Displays the device names and user names as they are added to the ALF database.

Description

You can use the ALF ADD command to associate a terminal or port with a particular user name. This will enable certain users to log in to certain terminals or ports without specifying a user name.

The ALF ADD command adds a new record to the ALF database.

Examples

SYSMAN> ALF ADD TTA3 JBERGERON 
SYSMAN> ALF ADD "MN34C3/LC-1-2" FMARTIN /PORT 
 
      

In this example, the first command assigns terminal TTA3 to user JBERGERON. The second command assigns port MN34C3/LC-1-2 to user FMARTIN.

SYSMAN> ALF ADD VMS:.ZKO.VMSORG.SYSMAN.CLIENT1::SYSTEM FOOBAR
      

In this example, VMS:.ZKO.VMSORG.SYSMAN.CLIENT1::SYSTEM is the value for the device parameter, which is assigned to FOOBAR.

ALF REMOVE

Removes one or more records from the ALF database.

Requires read (R) and write (W) access to the SYSALF database (SYS$SYSTEM:SYSALF.DAT).

Format

ALF REMOVE device

Parameter

device

Specifies the terminal name or port name whose record you want to remove from ALF. The device name is required, even if you use qualifiers with the ALF REMOVE command.

You can use wildcard characters in the terminal name or port name. For example, if you specify the device TTA*, the system removes all records that start with the string TTA. The system does not, however, remove any records that start with the string <nodename>$TTA (where <nodename> is the system's SCSNODE name). To remove records starting with $, you would have to specify $TTA* or use two wildcards: *TTA*.

If you omit wildcard characters and enter a REMOVE command, SYSMAN attempts to match the device name exactly. If more than one record matches the criteria, SYSMAN displays an error message.

Qualifiers

/USERNAME=user

Enables you to remove a record in ALF for a specific user associated with a device. You must also enter the device when you use the /USERNAME qualifier. You can use wildcard characters with the /USERNAME qualifier.

/CONFIRM

Displays a message asking you to verify that you want to remove the record.

/LOG

Displays each device name and user name after it has been removed from the ALF database.

Description

The ALF REMOVE command removes one or more records from the ALF database.

Examples

SYSMAN> ALF REMOVE WORK1/USERNAME=*
      

The command in this example removes the records of the WORK1 device from the ALF datebase for all users. The asterisk (*) replaces user names.

SYSMAN> ALF REMOVE */USERNAME=*
      

The command in this example removes all records from the ALF database. The first asterisk (*) replaces device names; the second asterisk replaces user names.

SYSMAN> ALF REMOVE _TTA3:
SYSMAN> ALF REMOVE */USERNAME=SMITHSON
 
      

In this example, the first command removes the record for terminal TTA3. The second command removes all records (for all devices) assigned to user name SMITHSON.

SYSMAN> ALF REMOVE *TTA*
      

The command in this example removes all records for devices containing the string TTA.

SYSMAN> REMOVE TTA
      

This command produces the following error message:

%SYSMAN-E-ALFWILCRDREQ, more than one record might match - Wildcard or unit number of device required.

For example, the following command issued from a system running OpenVMS Version 6.1 or lower to a system running OpenVMS Version 6.2 produces no error messages and deletes all records that match FOOBAR$TTA:

SYSMAN> SET ENVIRONMENT/NODE=FOOBAR ! FOOBAR runs OpenVMS Version 6.2 %SYSMAN-I-ENV, current command environment: Individual nodes: FOOBAR Username SYSTEM will be used on nonlocal nodes SYSMAN> ALF REMOVE TTA ! Does not produce an error message SYSMAN>

If you issue the same command from a system running OpenVMS Version 6.1 or lower to another system running OpenVMS Version 6.1 or lower, it produces the following error message:

%SYSMAN-I-NODERR, error returned from node FOO -SMI-E-ALFNOMATCH, no records matched search criteria

This is due to incorrect processing of wildcards prior to OpenVMS Version 6.2.

ALF SHOW

Displays one or more records from the ALF database.

Requires read (R) and write (W) access to the SYSALF database (SYS$SYSTEM:SYSALF.DAT).

Format

ALF SHOW [device]

Parameter

[device]

Specifies the terminal name or port name whose record you want to display. You can use wildcard characters in the terminal name or port name. Certain restrictions in wildcard matching of ALF records exist, as shown in the examples section.

Qualifiers

/USERNAME=user

Displays the records held by the specified user. You can use wildcard characters with this qualifier.

/OUTPUT[=filespec]

Directs the output of the command to a file. If you do not include a file specification with this qualifier, SYSMAN writes the output to the file SYSMAN.LIS in your default directory.

Description

The ALF SHOW command displays one or more records in the ALF database.

Examples

SYSMAN> ALF SHOW TTA* /USERNAME=MANESS /OUTPUT=ALF.TXT 
 
      

In this example, the records for all terminals named TTAx that are assigned to user MANESS are selected and directed to the file ALF.TXT.

SYSMAN> ALF SHOW TTA*
      

This command displays only those records that start with the string TTA.

SYSMAN> ALF SHOW TTA
      

This command displays only those records that start with the string <nodename>$TTA.

SYSMAN> ALF SHOW *TTA
      

This command displays records that have device names ending with TTA.

SYSMAN> ALF SHOW *TTA*
      

This command displays all records that contain the string TTA.
