SHUTDOWN
A server instance enters the shutdown state as a result of a graceful shutdown or forced
shutdown process.
During the graceful shutdown process, a server instance goes through the following
state transitions:
RUNNING→SUSPENDING→STANDBY→SHUTTING DOWN→SHUTDOWN
For more information about the graceful shutdown process, see “Graceful Shutdown”
on page 6-9.
During the forced shutdown process, a server instance goes through the following state
transitions:
any state→STANDBY→SHUTDOWN
For more information about the forced shutdown process, see “Forced Shutdown” on
page 6-13.
FAILED
A server instance enters the FAILED state when one or more critical services become
dysfunctional. When a server instance finds one or more critical subsystems have
failed, the server instance sets its state to
FAILED to indicate that the it cannot reliably
host an application.
To recover from the
FAILED state, a server instance must be shutdown and restarted,
either manually, or automatically with Node Manager, if it is configured on the host
machine. For information about automatic restarts, see “Shutdown Failed Managed
Servers” on page 3-7.
A server instance can only enter the
FAILED state from the RUNNING state:
RUNNING→FAILED
UNKNOWN
If a server instance cannot be contacted, it is considered to be in the UNKNOWN state.
