11.4.2 Saving Changes to the Active Configuration
▼
To save changes to the active configuration:
1. Select File
→
Save. The screen displays the Save Type dialog box.
2. Select one of the following options to specify how you want the updates
to be applied to the active configuration:
Wait for servers to become idle
- If a modified server still has active client
connections, the software sets the state of the server to Draining. The server
stops accepting client connections and is not considered available for load
control. (Clients are not directed to the manager system containing the
server unless they explicitly request a resource on that server.) When all
active connections terminate, the configuration is updated and the server is
restarted with the new configuration.
Changes should be made immediately - Each modified server is
immediately terminated and restarted with the new configuration.
In general, when the active configuration is modified and saved, only the
servers that were changed are affected. The primary manager system writes the
new configuration to disk locally and then initiates a distributed save
operation to each active secondary manager. When the distributed save is
complete and the configuration is stored on the active secondary manager
systems, a reply is sent to the SunGMI that initiated the Save command and the
operation is complete.
11.5 Managing an Off-line Configuration
You can use off-line configurations to make changes in an orderly fashion. Off-
line configurations allow you to make a series of updates off-line and then
bring them on-line at a specific time. The following sections describe how to
create and modify off-line configurations and how to activate an off-line
configuration.
