set(8dts)

Modifies characteristics for the DTS entity.

Synopsis

dtscp set characteristic

Arguments

characteristic
The name and value of one or more characteristics to be modified. Valid values for characteristic are described in the following list. These values are described in more detail in the Description topic.

Description
The set command modifies the characteristics you specify for the DTS entity. The modifiable characteristics and their values are described in the following list.

check interval [relative-time]
Specifies the amount of time between checks for faulty servers. Applicable only for servers that have external time providers.

Default: 0-01:30:00.000
Value: 0-00:00:30.000 10675199-02:48:05.000

courier role [role]
Specifies a server's interaction with the set of global servers.

Default: backup courier

The following values are valid:

backup courier
The local server becomes a courier if none are available on the LAN.

courier
The local server synchronizes with the global set of servers.

noncourier
The local server does not synchronize with the global set of servers.

error tolerance [relative-time]
Specifies the maximum separation allowed between the local clock and the computed time before synchronization becomes abrupt rather than gradual (monotonic).

Default: 0-00:10:00.000
Value: 0-00:00:00.500 10675199-02:48:05.000

global set timeout [relative-time]
Specifies the amount of time the node waits for a response to a global synchronization request before sending another request or declaring a global server to be unavailable. The number of attempts made to reach the server is controlled by the query attempts characteristic.

Default: 0-00:00:15.000
Value: 0-00:00:00.000 0-00:10:00.000

local set timeout [relative-time]
Specifies the amount of time the node waits for a response to a local synchronization request before sending another request or declaring a server to be unavailable. The number of attempts made to reach the server is controlled by the query attempts characteristic.

Note that the local set timeout value controls only the initial contact with a time provider. During this initial contact, the time provider itself determines the timeout value for actually reporting back times. This allows a time provider attached to a slow source like a modem to request that dtsd wait for a longer interval.

Default: 0-00:00:05.000
Value: 0-00:00:00.000 0-00:01:00.000

maximum inaccuracy [relative-time]
Specifies the inaccuracy limit for the node. When the node exceeds the maximum inaccuracy setting, it attempts to synchronize.

Default: 0-00:00:00.100
Value: 0-00:00:00.000 - 10675199-02:48:05.000

query attempts [integer]
Specifies the number of attempts that a node makes to contact a server before the node considers the server unavailable.

Default: 3
Value: 110

server entry name [name]
Specifies a server's CDS entry name; name represents the name of the system or node that is the server's client. The default setting is the recommended value.

Default: /.:/hosts/hostname/dts-entity

server group name [name]
Specifies the name of the security group that DTS uses for authentication checks. DTS clerks and servers do not accept time values from DTS servers that are not included in this group.

server principal name [name]
Specifies a server's principal name for authentication purposes; name represents the name of the system or node that is the server's client. The default setting is the recommended value.

Default: /.:/hosts/hostname/self

servers required [integer]
Specifies the minimum number of servers required for synchronization. Settings of 1 or 2 may cause unreliable computed times.

Default: 1 (clerks) 3 (servers)
Value: 110

synchronization hold down [relative-time]
Specifies the interval a node must wait to synchronize. Also specifies synchronization frequency when a node reaches the value specified by the maximum inaccuracy characteristic.

Clerks:
Default: 0-00:10:00.000
Value: 0-00:00:30.000 01-00:00:00.000

Servers:
Default: 0-00:02:00.000
Value: 0-00:00:30.000 01-00:00:00.000

Privileges Required
You must have w (write) permission on the ACL associated with the DTS entity to execute the command.

Notes
This command is replaced at Revision 1.1 by the dcecp command and may not be provided in future releases of DCE.

The following two commands are obsolete. Use the replacements shown.

set lan timeout
This command is the same as set local set timeout.

set wan timeout
This command is the same as set global set timeout.

Examples

1. The following example shows how to set the check interval characteristic to 30 seconds:

dtscp> set check interval 00-00:00:30.000

2. The following example shows how to set the number of servers required before the entity can synchronize:

dtscp> set servers required 4

3. The following example shows how to set the courier role for a server:

dtscp> set courier role backup courier

4. The following example sets the error tolerance characteristic to seven minutes:

dtscp> set error tolerance 0-00:07:00.000

5. The following example sets the global set timeout characteristic to 45 seconds:

dtscp> set global set timeout 0-00:00:45.000

6. The following example sets the local set timeout characteristic to five seconds:

dtscp> set local set timeout 0-00:00:05.000

7. The following example sets the maximum inaccuracy characteristic to three milliseconds:

dtscp> set maximum inaccuracy 0-00:00:00.300

8. The following example sets the server entry name characteristic to /.:/hosts/orion/dts-entity:

dtscp> set server entry name /.:/hosts/orion/dts-entity

9. The following example sets the server principal name characteristic to /.:/hosts/vega/dts-entity:

dtscp> set server principal name /.:/hosts/vega/dts-entity

10. The following example sets the synchronization hold down characteristic to 15 minutes:

dtscp> set synchronization hold down 0-00:15:00.000
