>          Issue Type: Feature Request
>          Components: Domain Management

> An EAP customer request:
> Right now, any changes done via the CLI to an active profile are pushed to all instances immediately. Some go life, some at reload only
> While batch mode can be used to bundle a number of changes in one go, there is currently no way to tell individual servers or server-groups when to accept updates or not.
> This proposal is to allow a config switch on servergroup level and on individual server level to accept a configuration change selectively:
> 1. immediate, the current situation, being the default
> 2. at restart only
> 3. at explicit being told so, e.g. when a "reload" is ordered
> Example:
> <server name="server-three" group="other-server-group" updates="immediate">
> the default when the attribute is absent
> <server name="server-three" group="other-server-group" updates="start">
> <server name="server-three" group="other-server-group" updates="explicit">
> The latter could then be triggered with:
> /host=master/server-config=server1:reload
> Similar option could be set on servergroup level, with a similar reload command on that level
