Use
the DOMAINORIGIN statement to specify the domain origin that is appended
to the host name to form the fully qualified domain name of a host.
Syntax
>>-+--------------+--DOMAINORIGIN--origin----------------------><
'-system_name:-'
Parameters
- system_name:
- The name of the system to which this statement applies. See system_name considerations for a complete
description of this parameter.
Requirement: The colon is
required.
- origin
- The domain origin is appended to the host name. This name usually
has imbedded dots.
Guidelines: The values for the domain
name must conform to the following rules:
- Maximum of 249 characters.
- Must contain one or more tokens separated by a period.
- Each token must be at least one character.
- Each token must start with a letter or number.
- Remaining characters in each token must be a letter, number, or
hyphen.
- The length of the host name plus the length of the domain name
must be less than or equal to 254.
Examples
This example appends the domain
origin of BOBS.YOUR.UNCLE to the host name:
DOMAINORIGIN BOBS.YOUR.UNCLE
Usage notes
- No case translation is performed on the domain origin.
- If the resolver is passed a host name that does not contain any
dots (in dotted decimal notation), the domain origin is appended to
the host name. If the host name passed to the resolver contains dots,
the value of the OPTIONS NDOTS:n statement influences how the DOMAINORIGIN
value is used. See OPTIONS statement.
- The DOMAINORIGIN configuration statement must be customized at
each site.
- Additionally, the domain origin can be set from the z/OS® shell environment by exporting the LOCALDOMAIN
environment variable.
>>-export--LOCALDOMAIN=origin----------------------------------><
The setting of the LOCALDOMAIN as an environment
variable overrides any setting for DOMAIN, DOMAINORIGIN, or SEARCH
found in TCPIP.DATA.
