Configuring a Primary Master Name Server
Resource Limits Options: The server’s usage of many system
resources can be limited. If a specific limit is not supported on a given
operating system, a warning will be issued.
Scaled values are allowed when specifying resource limits. For example,
1G can be used instead of 1073741824 to specify a limit of one gigabyte.
Specifying unlimited requests unlimited use, or the maximum
available amount. default uses the limit that was in effect when the
server was started. Table 3-8 lists the resource options available.
transfer-in number; The maximum number of inbound zone transfers that can be running
concurrently. The default value is 10. Increasing transfer-in
may speed up the coverage of slave zones, but it also may increase
the load on the local system.
transfers-out
number;
This option will be used in the future to limit the number of
concurrent outbound zone transfers. Currently, it is checked for
syntax, but is otherwise ignored.
transfers-per-ns
number;
The maximum number of inbound zone transfers (named-xfer
processes) that can be concurrently transferring from a given remote
nameserver. The default value is 2. Increasing transfers-per-ns
may speed up the convergence of slave zones, but it also may
increase the load on the remote nameserver. The
transfers-per-ns may be overridden on a per-server basis by
using the transfers phrase of the server statement.
