Configuring the Initial DTS Server
dce_config utility creates the NonStop SQL/MP tables on this subvolume and
registers cdsd with SQL/MP.
After successful completion, dce_config issues this prompt regarding multiple-
LAN configuration:
Create LAN profile so clients and servers can be divided
into profile groups for higher performance in a multi-lan
cell?(n)
where the character shown in parentheses is the default response if you press
Return.
4. Enter y or n as appropriate.
The following actions occur:
•
cds-server principals are added to the security registry.
•
The CDS demons cdsclerk, cdsadv, and cdsd are started.
When the CDS components are operational, the namespace directories and objects
are created, remote procedure call (RPC) entries are added, and security permissions
are set.
The cell is now fully functional, and the Initial Cell Configuration menu is displayed. You
can perform the procedure described in Configuring the Initial DTS Server.
Configuring the Initial DTS Server
You should configure at least one distributed time service (DTS) server (the local
server dtsd demon) in any multiple machine cell. For authenticated RPC
interoperability, machines must be synchronized to within 5 minutes. Running a DTS
server on each machine ensures that the machine times are synchronized.
A DTS server can be either a time server (local, global, or time provider) or a clerk.
Time servers supply time values, and clerks synchronize the time between machines.
A minimum of three DTS servers (a local, a time-provider, and a clerk) is
recommended for a cell with three or more machines. If the cell contains multiple
LANs, at least one DTS server for each LAN should be a global time server.
Although the DTS clerks keep the machines in a cell synchronized, collectively they all
can drift with respect to Coordinated Universal Time (UTC). To ensure that the time is
accurate, attach an external time source to at least one machine in the cell. Configure
a DTS time-provider server on those machines with external time sources. NonStop
DCE supports only one time provider, the null time provider. Configure a DTS null time
provider to start the demon dts_null_provider.
Note. NonStop DCE cdsadv does not start cdsclerk processes.
