6 Server Lifecycle

6-4 Configuring and Managing WebLogic Server

Understanding Server State

The following sections describe the key states that a server instance can have, the

processing associated with the state, and how the state fits into a sequence of state

transitions.

SHUTDOWN

In the SHUTDOWN state, a server instance is configured but inactive. A server instance

reaches the

SHUTDOWN state as a result of a graceful shutdown or forced shutdown.

A graceful shutdown can be initiated when the server instance is in the

RUNNING or the

STANDBY state. The graceful shutdown process consists of 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.

A forced shutdown can be initiated from any server state. The forced shutdown process

consists of the following state transitions:

any state→STANDBY→SHUTTING DOWN→SHUTDOWN

For more information about the forced shutdown process, see “Forced Shutdown” on

page 6-13.

For information about issuing stop commands, see “Starting and Stopping Servers” in

Administration Console Online Help.

STARTING

In the STARTING state, a server instance prepares itself to accept requests and perform

application processing. A server instance cannot accept requests while in the

STARTING state.

When a server instance starts itself, it retrieves its configuration data, starts its

kernel-level services, initializes subsystem-level services, deploys applications, and

loads and runs startup classes. For more information about the startup process, see

“Start” on page 6-8.
