Distributed Action Handler 25.4
Distributed Action Handler Help

# Host

The host name or IP address of the child server that the Distributed Action Handler communicates with.

In non-mirror mode, you can also specify a comma-separated list of host names of mirrored child servers to create a child server group.

NOTE: If you are using VDBs, you cannot also use server groups.

IMPORTANT: When you are using GSS authentication, (see GSSServiceName and RequireGSSAuth ) you must set `Host` to a fully qualified domain name (that is, you cannot use `localhost`, an IP address, or a host without the domain name, even if these values resolve to the correct server). Distributed Action Handler retrieves the Kerberos realm from the child server host name.
