chnamsv Command

Edit online

Purpose

Changes TCP/IP-based name service configuration on a host.

Syntax

chnamsv [ -a"Attribute=Value ..." | -A FileName ]

Description

The chnamsv high-level command changes a TCP/IP-based name service configuration on a host. The command changes the /etc/resolv.conf file only. The command does not change the name server database.

If you change the name service configuration for a client, the chnamsv command calls the namerslv low-level command to change the resolv.conf configuration file appropriately.

You could also use the System Management Interface Tool (SMIT) smit namerslv fast path to run this command.

Flags

Examples

  1. To update the named server initialization files, enter the command in the following format:
