dtscp(8dts)

Starts the DTS control program

Synopsis

dtscp

Notes
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
This topic 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 - Core Components.

The DTS control program commands are:

· The advertise command configures the DTS server as a global server

· The change command modifies the epoch and sets the local time to a new time

· The create command establishes a DTS entity (a clerk or server)

· The delete command causes DTS to exit on the local node

· The disable command suspends a DTS entity

· The enable command starts a DTS entity

· The exit command ends the dtscp management session and returns you to the system prompt

· The help command invokes the dtscp help service.

· The quit command ends the dtscp management session and returns you to the system prompt

· The set command modifies characteristics of a DTS entity

· The show command displays characteristics of a DTS entity

· The synchronize command synchronizes the system clock with the time obtained from DTS servers in the network

· The unadvertise command removes the global server entry

· The update command gradually adjusts the system clock to a new time

For more information on any of the dtscp commands, see the appropriate command.

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 DTS control program by entering the dtscp command. For example:

$ dtscp
dtscp>

At this prompt you can enter any control program command; for example:

dtscp> 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. For example:

dtscp> update time 1990-08-03-05:45:28.000+01:00I00.500
/ / / /
Command [Argument] Variable
--------
[Attribute]

Abbreviations
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:

dtscp> ena set clo tru

Attributes
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
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.

Global Servers
Show the global servers known by this DTS entity.

Local Servers
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
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 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 I----- 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.
