OpenVMS DCL Dictionary
This command connects the user's terminal to the password-protected
service PURSE. The password is BEOR.
SET HOST/RLOGIN
Allows you to log in to a remote host over a TCP/IP connection and
start an interactive terminal session by accessing the RLOGIN
application.
Format
Note
You can specify the IPhostname or the IPaddress, but
not both.
|
Parameter
IPhostname
Specifies the IP host name of the remote host.
IPaddress
Specifies an IP address of the remote host.
Description
The SET HOST/RLOGIN command allows you to log in to a remote host by
invoking RLOGIN client software that runs on your system. Once you
start the terminal session, you can enter commands interactively on the
remote host. The parameter that specifies the remote host is either an
IP host name or an IP address.
Qualifiers
/AUTHENTICATE
Specifies that Kerberos authentication should be used for acquiring
access to the remote node.
/PASSWORD=password
Optional qualifier that specifies the password of the user logging in
to the remote host.
/TERMINAL_TYPE=type
Sets the terminal emulator to one of the following terminal types:
VT100, VT200, VT300, VT400, VT500.
/TRUNCATE_USERNAME
Specifies that the current user name should be truncated to 8
characters before attempting to connect to the remote node. The
qualifier is required for communication with systems that limit the
size of their login names to 8 characters. The /TRUNCATE_USERNAME
qualifier is ignored if /USERNAME is specified.
/USERNAME=username
Specifies the user name for logging in to the remote node. The user
name can be enclosed in quotes to preserve the case of the user name
for case sensitive systems such as UNIX systems. If the /USERNAME
qualifier is not specified, the default is the current user's user name.
Example
|
$ SET HOST/RLOGIN remotehst1
|
This example creates an RLOGIN connection to remote host
remotehst1 over a TCP/IP connection.
SET HOST/TELNET
Connects you to a remote host over a TCP/IP connection by invoking the
TELNET application.
Format
Note
You can specify the IPhostname or the IPaddress, but
not both.
|
Parameter
IPhostname
Specifies the IP host name of the remote host.
IPaddress
Specifies an IP address of the remote host.
Description
The SET HOST/TELNET command allows you to connect to a server on a
remote system by invoking the TELNET client software that runs on your
system. The parameter that specifies the remote host is either an IP
host name or an IP address. Most of the attributes are negotiated with
the remote node. The qualifiers are used only in exception cases (for
example, cases where a remote server does not support a negotiated
parameter but requires a certain characteristic for the connection).
Qualifiers
/AUTHENTICATE
Specifies that Kerberos authentication should be used for acquiring
access to the remote node.
/PORT=port
Specifies the remote TCP port to use. The default is 23.
/TERMINAL_TYPE=type
Sets the terminal emulator to one of the following terminal types:
VT100, VT200, VT300, VT400, VT500.
Example
|
$ SET HOST/TELNET remotehst2
|
This example creates a TELNET connection to remote host
remotehst2 over a TCP/IP connection.
SET HOST/TN3270
Connects you to a remote IBM host over a TCP/IP connection, causing the
local keyboard to emulate an IBM 3279-class terminal keyboard by
invoking the TN3270 terminal emulator.
Format
Note
You can specify the IPhostname or the IPaddress, but
not both.
|
Parameter
IPhostname
Specifies the IP host name of the remote host.
IPaddress
Specifies an IP address of the remote host.
Description
The SET HOST/TN3270 command allows you to connect with a TELNET server
on a remote IBM system by invoking the TN3270 terminal emulator TELNET
client program on the local host. The parameter that specifies the
remote host is either an IP host name or an IP address. The TN3270
client will automatically determine the terminal type (IBM-3278-2,
IBM-3278-3, IBM-3278-4, or IBM-32798-5).
Qualifiers
/AUTHENTICATE
Specifies that Kerberos authentication should be used for acquiring
access to the remote node.
/PORT=port
Specifies the remote TCP port to use. The default is 23.
/TERMINAL_TYPE
Sets the terminal emulator to one of the following terminal types:
VT100, VT200, VT300, VT400, VT500.
Example
|
$ SET HOST/TN3270 remotehst3
|
This example creates a connection to a TELNET server on the remote IBM
system remotehst3 over a TCP/IP connection.
SET KEY
Sets and locks the key definition state for keys defined with the
DEFINE/KEY command.
Format
SET KEY
Description
When you define keypad keys using the DEFINE/KEY command, you can
assign a specific state name to the key definition. If that state is
not set when you press the key, the definition is not processed. Use
the SET KEY command to change the current state to the appropriate
state.
Qualifiers
/LOG (default)
/NOLOG
Controls whether the system displays a message indicating that the key
state has been set.
/STATE=state-name
/NOSTATE
Specifies the name of the state. The state name can be any alphanumeric
string. If you omit the /STATE qualifier or use the /NOSTATE qualifier,
the current state is left unchanged. The default state is DEFAULT.
Example
The SET KEY command in this example sets the key state to the state
EDITING. You can now use the key definitions that were defined for the
state EDITING.
SET LOGINS
Sets the interactive limit (number of interactive users allowed on the
system), or displays the interactive limit and the current number of
interactive users.
Requires OPER (operator) privilege to set the login limit.
Format
SET LOGINS
Parameters
None.
Description
The SET LOGINS command is not retroactive. All users logged in to the
system before you enter the SET LOGINS command are not affected by the
command; however, once the limit you set is reached, no more users can
log in to the system until someone else logs out. Users with the OPER
privilege are not affected by the limit.
If you do not specify a parameter value with the /INTERACTIVE=n
qualifier, the SET LOGINS command displays the following information:
Login quotas - Interactive limit=x, Current interactive value=y
|
The value x represents the current interactive limit, and the
value y represents the number of users currently logged in to
the system.
Qualifier
/INTERACTIVE[=n]
Establishes the number of interactive users allowed to gain access to
the system. If the parameter n is specified, the interactive
limit is set to the value n. If the parameter n is
not specified, the SET LOGINS command displays the current interactive
limit and the number of interactive users.
Examples
| #1 |
$ SET LOGINS/INTERACTIVE=5
%SET-I-INTSET, login interactive limit=5, current interactive value=3
|
In this example, the SET LOGINS command specifies that only five
interactive users can be logged in to the system.
| #2 |
$ SET LOGINS/INTERACTIVE
%SET-I-INTSET, login interactive limit=9, current interactive value=6
|
When the SET LOGINS command is entered without a parameter, as shown in
this example, the /INTERACTIVE qualifier requests that the current
status of the login quotas be displayed. The message returned indicates
that the maximum number of interactive users allowed on the system is 9
and that the number of interactive users currently logged in is 6. No
change is made.
SET MAGTAPE
Defines the default characteristics associated with a specific magnetic
tape device for subsequent file operations.
The SET MAGTAPE command is valid for magnetic tape devices
mounted with foreign volumes.
Format
SET MAGTAPE device-name[:]
Parameter
device-name[:]
Specifies the name of the magnetic tape device for which the
characteristics are to be set. The device must not be currently
allocated to any other user.
Qualifiers
/DENSITY=density-value
Specifies the default density for all write operations on the magnetic
tape device when the volume is mounted as a foreign tape or as an
unlabeled tape.
Valid density values are:

/END_OF_FILE
Writes a tape mark at the current position on the magnetic tape volume.
/FAST_SKIP=option
Allows you to skip by file mark or by record.
Note
This tape positioning qualifier is for use on local SCSI tape drives
only.
|
|
PER_IO (default)
|
Allows a local MK device to use the skip-by-filemarks function. The
tape drive must be able to do a SCSI READ POSITION command and report
blank check at end-of-data. The IO$M_ALLOWFAST function modifier must
be supplied with IO$_SKIPFILE. Otherwise, the tape will skip files
using the skip-by-records function.
|
|
ALWAYS
|
Allows a local MK device to use the skip-by-filemarks function. The
tape drive must be able to support the skip-by-filemarks function, and
no modifications should be needed to the IO$_SKIPFILE function.
|
|
NEVER
|
Specifies that a local MK device skip only by records. If you use a
utility that depends on the semantics of skipping with skip-records,
you may also need to use this option because it causes BACKUP or COPY
to use the previous positioning.
|
/LOG
/NOLOG
Displays information about the operations performed on the magnetic
tape volume.
/LOGSOFT (default)
/NOLOGSOFT
Controls whether soft errors on the specified device are to be logged
in the error log file. Soft errors are errors corrected by the hardware
without software intervention. This qualifier affects only devices that
support hardware error correction, such as the TU78 magnetic tape
drive. When used with other devices, this qualifier has no effect.
/MEDIA_FORMAT=[NO]COMPACTION
Controls whether data records are automatically compacted and blocked
together on a TA90E tape drive. Data compaction and record blocking
increase the amount of data that can be stored on a single tape
cartridge.
Note that once data compaction or noncompaction has been selected for a
given cartridge, that same status applies to the entire cartridge.
/RETENSION
Moves a TZK10 tape cartridge to the end of the tape, and then back to
the beginning of the tape. Use the /RETENSION qualifier on a regular
basis to help maintain the integrity of TZK10 tape cartridges.
The /RETENSION qualifier must be used in conjunction with the /REWIND
or /UNLOAD qualifier. The /RETENSION qualifier completes its action
before /REWIND or /UNLOAD. Use /RETENSION/REWIND when you want the tape
cartridge to remain loaded in the drive. Use /RETENSION/UNLOAD when you
want to unload the tape cartridge after the retension operation.
This qualifier only affects TZK10 tape cartridge drives and has no
effect on non-SCSI drives.
/REWIND
Requests that the volume on the specified device be rewound to the
beginning of the magnetic tape.
/SKIP=option
Requests that the magnetic tape volume be positioned according to any
of the following options:
|
BLOCK:
n
|
Skips the specified number of blocks.
|
|
END_OF_TAPE
|
Positions the volume at the end-of-tape (EOT) mark.
|
|
FILES:
n
|
Skips the specified number of tape marks (not files).
The tape is positioned just past the
nth tape mark. If
n is negative, the tape is still positioned after the
nth tape mark, not before it. If the tape is already
positioned immediately after a tape mark, a skip of -1 results in no
net movement. (The tape moves to the preceding mark, but is then
repositioned to the end of the mark, where it began.) For more
information on tape marks and files, refer to the OpenVMS System Manager's Manual.
|
|
RECORD:
n
|
Skips the specified number of records up to 32767.
|
/UNLOAD
Requests that the volume on the specified device be rewound and
unloaded.
Examples
| #1 |
$ MOUNT MTB1:/FOREIGN
$ SET MAGTAPE MTB1: /DENSITY=800
|
The MOUNT command in this example mounts a foreign tape on the device
MTB1. The SET MAGTAPE command defines the density for writing the
magnetic tape at 800 bpi.
| #2 |
$ MOUNT MTA0:/FOREIGN
$ SET MAGTAPE MTA0:/SKIP=FILES:4
|
The MOUNT command in this example mounts a foreign tape on the device
MTA0; the SET MAGTAPE command directs the magnetic tape position to
skip four files.
SET MESSAGE
Sets the format for system messages or specifies a process level
message file. Lets you override or supplement the system messages.
Format
SET MESSAGE [filespec]
Parameter
filespec
Specifies the name of the process level message file. Messages in this
file supersede messages for the same conditions in the system message
file or in an existing process message file. The file type defaults to
.EXE. The asterisk (*) and the percent sign (%) wildcard characters are
not allowed. If you do not specify this parameter, the qualifiers apply
to the system message file.
Description
The SET MESSAGE command specifies which message fields the OpenVMS
system displays. The message format is as follows:
When a process is created, the default is to display all four message
fields: facility, severity, identification, and text. To control which
fields of a message are displayed, specify the appropriate qualifiers.
For example, to omit the FACILITY field in message displays, specify
SET MESSAGE /NOFACILITY.
By including the SET MESSAGE command in your login command file, you
can select specific portions of the messages for your process.
Use the SET MESSAGE command, also, to override or supplement system
messages. Whenever any software detects an error and invokes the
$GETMSG system service, the message files are searched in the following
order: image message sections first, process-permanent message files
second, and the system message file last. Thus, with the SET MESSAGE
command, you can introduce messages earlier in the searching order; you
can either override or supplement the system messages. (Note that the
new message definitions affect only your process.)
If a process-permanent message file exists when you specify the SET
MESSAGE command with a file specification, the old file is removed and
the new file is added.
The message definitions you specify must result from a successful
compilation with the MESSAGE command. For full details on how to create
your own messages with the Message utility, refer to the OpenVMS Command Definition, Librarian, and Message Utilities Manual.
Qualifiers
/DELETE
Removes any process-permanent message files currently in effect. Do not
specify the filespec parameter with the /DELETE qualifier.
/FACILITY (default)
/NOFACILITY
Formats messages so that the facility name prefix appears.
/IDENTIFICATION (default)
/NOIDENTIFICATION
Formats messages so that the message identification prefix appears.
/SEVERITY (default)
/NOSEVERITY
Formats messages so that the severity level appears.
/TEXT (default)
/NOTEXT
Formats messages so that the message text appears.
Examples
| #1 |
$ TYPE XXX
%TYPE-W-OPENIN, error opening DB1:[MARSHALL]XXX.LIS; as input
-RMS-E-FNF, file not found
.
.
.
$ SET MESSAGE/NOIDENTIFICATION
.
.
.
$ TYPE XXX
%TYPE-W, error opening DB1:[MARSHALL]XXX.LIS; as input
-RMS-E, file not found
|
When the first TYPE command is entered in this example, the error
messages include all fields. Later, the SET MESSAGE command establishes
that the IDENT portion (the abbreviation for the message text) is
omitted in future messages.
The SET MESSAGE command in this example specifies that the message text
in NEWMSG.EXE supplements the existing system messages.
