restart-instance

Restarts a running Eclipse GlassFish instance

Synopsis

asadmin [asadmin-options] restart-instance [--help]
[--debug={false|true}] instance-name

Description

The restart-instance subcommand restarts a running Eclipse GlassFish instance. This subcommand requires secure shell (SSH) to be configured on the machine where the domain administration server (DAS) is running and on the machine where the instance resides.

SSH is not required if the instance resides on a node of type CONFIG that represents the local host. A node of type CONFIG is not enabled for communication over SSH.

You may run this subcommand from any machine that can contact the DAS.

The subcommand can restart any Eclipse GlassFish instance, regardless of how the instance was created. For example, this subcommand can restart an instance that was created by using the create-local-instance(1) subcommand.

When this subcommand restarts an instance, the DAS synchronizes the instance with changes since the last synchronization as follows:

  • For the config directory, the DAS synchronizes the instance with all changes.

  • For the applications directory and docroot directory, only a change to a top-level subdirectory causes the DAS to synchronize all files under that subdirectory.

    If a file below a top level subdirectory is changed without a change to a file in the top level subdirectory, full synchronization is required. In normal operation, files below the top level subdirectories of these directories are not changed. If an application is deployed and undeployed, full synchronization is not necessary to update the instance with the change.

If different synchronization behavior is required, the instance must be stopped and restarted by using following sequence of subcommands:

  1. stop-instance(1)

  2. start-instance(1)

This subcommand is supported in remote mode only.

Options

asadmin-options

Options for the asadmin utility. For information about these options, see the asadmin(1M) help page.

--help

Displays the help text for the subcommand.

--debug

Specifies whether the instance is restarted with Java Platform Debugger Architecture (JPDA)(https://docs.oracle.com/en/java/javase/17/docs/specs/jpda/jpda.html) debugging enabled. Possible values are as follows:

true

The instance is restarted with JPDA debugging enabled and the port number for JPDA debugging is displayed.

false

The instance is restarted with JPDA debugging disabled.

The default is the current setting of this option for the instance that is being restarted.

Operands

instance-name

The name of the Eclipse GlassFish instance to restart. If the instance is not running, the subcommand displays a warning message and attempts to start the instance.
