NAME [Toc] [Back]
dtscp - DTS control program
SYNOPSIS [Toc] [Back]
dtscp
NOTES [Toc] [Back]
With the exception of the following subcommands, this command is
replaced at Revision 1.1 by the dcecp command. This command may be
fully replaced by the dcecp command in a future release of DCE, and
may no longer be supported at that time.
+ exit
+ help
+ quit
DESCRIPTION [Toc] [Back]
This section describes the commands for the DCE Distributed Time
Service (DTS) control program (dtscp). The DTS control program is a
command-line interface that enables you to synchronize, adjust, and
maintain the system clocks in a distributed network. For a detailed
explanation of system clock synchronization and management, see the
OSF DCE Administration Guide.
The DTS control program commands are
+ The advertise command, which configures the DTS server as a
global server
+ The change command, which modifies the epoch and sets the local
time to a new time
+ The create command, which establishes a DTS entity (a clerk or
server)
+ The delete command, which causes DTS to exit on the local node
+ The disable command, which suspends a DTS entity
+ The enable command, which starts a DTS entity
+ The exit command, which ends the dtscp management session and
returns you to the system prompt
+ The help command which invokes the dtscp help service.

+ The quit command, which ends the dtscp management session and
returns you to the system prompt
+ The set command, which modifies characteristics of a DTS entity
+ The show command, which displays characteristics of a DTS entity
+ The synchronize command, which synchronizes the system clock with
the time obtained from DTS servers in the network
+ The unadvertise command, which removes the global server entry
+ The update command, which gradually adjusts the system clock to a
new time
For more information on any of the above dtscp commands, see the
appropriate reference page in this chapter.
You can use control program commands from within the control program
or from the system prompt. To enter DTS commands from within the
control program, first start the control program by entering the dtscp
command. For example:
dtscp
tscp>
At this prompt you can enter any control program command; for example:
tscp> show current time
To leave the control program and return to the system prompt, enter
the exit command.
To enter DTS commands from the system prompt (interactively or in a
command procedure) enter the dtscp command with an internal command of
the control program as the first argument. The control program
executes the command without displaying the control program prompt.
For example, you can enter the synchronize command as follows:
dtscp synchronize
Some dtscp commands have optional arguments or attributes; there may
also be optional variables for the arguments and attributes.
See the following sample command:
tscp> update time 1990-08-03-05:45:28.000+01:00I00.500

Abbreviations [Toc] [Back]
You can enter as few as three characters for each DTS command or
argument; DTS commands and arguments are unique for three characters
or more. For example, rather than entering the command enable set
clock true, you can enter the following abbreviated command:
tscp> ena set clo tru
Attributes [Toc] [Back]
The dtscp set and show commands have several attributes-pieces or sets
of data associated with them. The attribute groups are categorized as
follows:
Characteristics [Toc] [Back]
Set or show the entity's operation.
Counters Show the number of occurrences of an event since the entity
was enabled.
Status Show the current state of the entity. (The DTS entity has
four status attributes.)
Global Servers [Toc] [Back]
Show the global servers known by this DTS entity.
Local Servers [Toc] [Back]
Show the local servers known by this DTS entity.
Individual attributes within each of the previously listed groups are
described in the reference pages for the set and show commands. The
show command also allows you to specify attribute groups.
Time Stamps [Toc] [Back]
All responses to commands contain a timestamp. The following example
shows a typical DTS time display:
1993-03-16-14:29:47.52000-05:00I000.003
The timestamp uses the DTS format that is explained in Chapter 15 of
the OSF DCE Administration Guide-Core Components. In this example,
the year is 1993, the day is March 16, and the time is 14 hours, 29
minutes, and 47.52 seconds. A negative Time Differential Factor (TDF)
of 5 hours and an inaccuracy of 3 milliseconds are included in the

timestamp.
Note: An inaccuracy value of ----- indicates an infinite
inaccuracy. This value appears in time displays before
a node's initial synchronization or after you enter the
change command without specifying an inaccuracy value.
