The state in which this server should be started. If you specify
STANDBY, you must also enable the domain-wide
administration port.
In the RUNNING
state, a server offers its services
to clients and can operate as a full member of a cluster. In the
ADMIN
state, the server is up and running, but
available only for administration operations, allowing you to
perform server and application-level administration tasks without
risk to running applications. In the STANDBY
state, a
server instance does not process any request; its regular Listen
Port is closed. The Administration Port is open. It only accepts
life cycle commands that transition the server instance to either
the RUNNING
or the SHUTDOWN
state. Other
Administration requests are not accepted. A
STANDBY
server's only purpose is to resume into the
RUNNING
state quickly; it saves server startup
time.
