HP-UX IP Address and Client Management Administrator's Guide (October 2009)

Table 1-8 Zone Transfer Options (continued)
DescriptionOption
This option specifies the maximum number of inbound zone transfers
(named-xfer processes) that run concurrently from a given remote
name server. The default value is 2. Increasing the value of
transfers-per-ns speeds up the convergence of slave zones. It
also increases the load on the remote name server.
You can override the transfers-per-ns on a per-server basis by
using the transfers option of the server statement.
transfers-per-ns number;
This option specifies the IPv4 address for inbound zone updates,
which is also the source address for refresh queries and forwarded
dynamic updates. If not set, it defaults to a system-controlled value,
which is usually the address of the interface close to the remote end.
transfer-source
This option is similar to transfer-source, except that zone
transfers are performed using an IPv6 address.
transfer-source-v6
This option specifies whether the name server must use the alternate
transfer sources. This option defaults to no if views are specified;
otherwise, this option defaults to yes (for BIND 8 compatibility).
use-alt-transfer-sourc e
yes_or_no;
Resource Limit Options
Resource limit options enable you to limit the server’s usage of the system resources. If a given
operating system does not support a specific limit, a warning is issue.
You can use scaled values to specify resource limits. For example, you can use 1G instead of
1073741824 to specify a limit of one gigabyte. Specifying unlimited specifies unlimited usage,
or the maximum available amount. default specifies the limit that was in effect when the server
was started.
Table 1-9 describes the resource options available.
Table 1-9 Resource Limit Options
DescriptionOption
This option specifies the maximum size of a core dump. The default value is
default.
coresize size_spec ;
This option specifies the maximum amount of data memory the server uses. The
default value is default.
datasize size-spec ;
This option specifies the maximum number of files the server can open
concurrently. The default value is unlimited.
NOTE: The server cannot set an unlimited value for certain operating systems
and cannot determine the maximum number of open files the kernel can support.
On such systems, specifying unlimited causes the server to use rlim_max for
RLIMIT_NOFILE or the value returned by sysconf(_SC_OPEN_MAX),
depending on which contains the higher value. If the actual kernel limit is larger
than this value, use limit files to specify the limit explicitly.
file size_spec ;
Specifies the maximum amount of stack memory the server can use. The default
value is default.
stacksize size_spec ;
Server Resource Limits
The server resource limit options set limits on the server’s resource consumption that are enforced
internally by the server rather than by the operating system. Table 1-10 describes the server
resource limit options.
