2. Select the name of the DNS configuration file by entering the SELECT DNSCONF
command. Include volume and subvolume name with the configuration file
name, as shown in Figure 3-1. The warning statement in this step is nothing to
worry about; the DNS configuration is initialized in step 8 below.
Then select the definition operating mode by entering the SELECT DEFINITION
ON command. This command is very important for completing the initialization
process. When DNSCOM enters definition mode, it responds with a message to
that effect.
3. When DNSCOM creates the DNS database files later in this sequence of steps, it
assigns them by default to the subvolume that was current when you started
DNSCOM. But if you would like the files created in a different subvolume, you
can specify this by entering the VOLUME or CMDVOL command followed by the
RESET DNSFILE * command. In the example, the subvolume $ENGIN2.DNS is
specified.
Note If you anticipate heavy activity against the DNS database, consider spreading these database files on
more than one disk volume. Refer to the Introduction to NonStop System Operations for more information
on capacity management.
4. In the next step, you enter a sequence of commands that requires the keyword
DNS as part of each entry. If you would like to simplify these entries by
eliminating this keyword, enter the ASSUME command and specify DNS as the
default object. DNSCOM prints a message confirming this default.
5. Now you are ready to specify configuration values to be used in step 8, below,
when DNS is actually initialized. DNS uses these values to set the DNS owner
and security and to determine the sizes of various files in the DNS database.
These values indicate the maximum number of domains, subsystem-manager
processes, types, and names to be defined at this node. To specify this set of
values, use as a basis the maximum number of names you plan to define. Then
specify the values by using the SET DNS command as shown in Figure 3-1.
