STANDBY
In the STANDBY state, a server has initialized all of its services and applications, can
accept administration commands, and can participate in cluster communication.
However, it does not accept requests from external clients.
The server instance can enter the
STANDBY if:
! It is started in standby mode. Starting a server in STANDBY state is a method of
keeping a server available as a “hot” backup, especially in a high-availability
environment. A server instance started in standby can be quickly brought to the
running state, as necessary to replace a failed server instance. Starting a server
instance in standby mode requires a domain-wide administrative port. For more
information, see “Administration Port Requires SSL” on page 11-9.
You can start a server instance in standby mode using the Start this server in
standby mode command on the Server
Control tab. You can also set a default
startup mode for a server instance on the Server
ConfigurationGeneral tab of
the Administration Console. The process of starting a server in standby mode
consists of the following state transitions:
