CHGTCPDMN (Change TCP/IP Domain) Command
Purpose
The Change TCP/IP Domain Information command is used to allow the user to
change the host/domain names and server information.
Restrictions: You must have *IOSYSCFG special authority to use this
command.
Optional Parameters
HOSTNAME The hostname of this system. This name should also be
defined in the local host table or at the domain name server.
*SAME: The HOSTNAME value does not change if it was previously
set.
host-name: Specify the host name to be used.
DMNNAME The name of the TCP/IP domain this system is a member of.
*SAME: The DMNNAME value does not change if it was previously set.
domain-name: Specify the domain name to be used.
HOSTSCHPTY Specifies whether to search the domain name server or
the local host table first for host name resolution.
*SAME: The HOSTSCHPTY value does not change if it was previously
set; otherwise, *REMOTE is used.
*REMOTE: Specify *REMOTE to contact a domain name server first.
The local host table is not searched until all attempts to reach a name server
have failed.
*LOCAL: Specify *LOCAL to always search the local host table prior
to contacting a remote name server.
INTNETADR The internet address of the domain name server host. The
dotted decimal form is used. A maximum of three domain name servers can be
specified. If the domain name server is contacted and either if does not
respond, or returns with a non-authoritative response then the next domain name
server in the list will be contacted.
*SAME: The INTNETADR value does not change if it was previously
set.
internet address: Specify the internet address to be
used.
PORT The remote port number used to contact the domain name server
listed in INTNETADR. Care should be taken in changing this value to something
other than port number 53, which is the domain name server well-known port.
*SAME: The PORT value does not change if it was previously set;
otherwise, 53 is used.
port number: Specify the remote port number to be used.
Valid values range from 1 to 65535.
PROTOCOL The protocol used to contact a remote name server. Care
should be taken in changing this value from *UDP, which is the protocol
typically used by domain name servers.
*SAME: The PROTOCOL value does not change if it was previously
set, otherwise, *UDP is used.
*UDP: The User Datagram Protocol is used to communicate with a
domain name server.
*TCP: The Transmission Control Protocol is used to communicate
with a domain name server.
DMNSVRRTY The number of retry attempts that are made to contact
each domain name server listed in INTNETADR, and the number of seconds this
AS/400 waits for a response from each attempt to contact a name server.
Element 1: Number of Retries
*SAME: The number of retries does not change if it was previously
set; otherwise, 2 is used.
number-retries: Specify the number of retries to be attempted.
Valid values range from 0 to 99.
Element 2: Time Interval
*SAME: The time interval does not change if it was previously set;
otherwise, 2 is used.
time-interval: Specify the number of seconds between retries.
Valid values range from 0 to 99. If a number of retries is set, the time
interval should be set to something other than 0.
