5 Administering GlassFish Server Instances
------------------------------------------

A GlassFish Server instance is a single Virtual Machine for the Java
platform (Java Virtual Machine or JVM machine) on a single node in which
GlassFish Server is running. A node defines the host where the GlassFish
Server instance resides. The JVM machine must be compatible with the
Java Platform, Enterprise Edition (Java EE).

GlassFish Server instances form the basis of an application deployment.
An instance is a building block in the clustering, load balancing, and
session persistence features of GlassFish Server. Each instance belongs
to a single domain and has its own directory structure, configuration,
and deployed applications. Every instance contains a reference to a node
that defines the host where the instance resides.

The following topics are addressed here:

* link:#gkrbn[Types of GlassFish Server Instances]
* link:#gkqal[Administering GlassFish Server Instances Centrally]

Types of GlassFish Server Instances
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Each GlassFish Server instance is one of the following types of
instance:

Standalone instance::
  A standalone instance does not share its configuration with any other
  instances or clusters. A standalone instance is created if either of
  the following conditions is met: +
  * No configuration or cluster is specified in the command to create
  the instance.
  * A configuration that is not referenced by any other instances or
  clusters is specified in the command to create the instance. +
  When no configuration or cluster is specified, a copy of the
  `default-config` configuration is created for the instance. The name
  of this configuration is instance-name`-config`, where instance-name
  represents the name of an unclustered server instance.
Shared instance::
  A shared instance shares its configuration with other instances or
  clusters. A shared instance is created if a configuration that is
  referenced by other instances or clusters is specified in the command
  to create the instance.
Clustered instance::
  A clustered instance inherits its configuration from the cluster to
  which the instance belongs and shares its configuration with other
  instances in the cluster. A clustered instance is created if a cluster
  is specified in the command to create the instance. +
  Any instance that is not part of a cluster is considered an
  unclustered server instance. Therefore, standalone instances and
  shared instances are unclustered server instances.

[[gkqal]][[GSHAG00187]][[administering-glassfish-server-instances-centrally]]

Administering GlassFish Server Instances Centrally
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Centralized administration requires the Distributed Component Object
Model (DCOM) remote protocol or secure shell (SSH) to be set up. If DCOM
or SSH is set up, you can administer clustered instances without the
need to log in to hosts where remote instances reside. For information
about setting up DCOM and SSH, see link:ssh-setup.html#gkshg[Enabling
Centralized Administration of GlassFish Server Instances].

Administering GlassFish Server instances centrally involves the
following tasks:

* link:#gkqch[To Create an Instance Centrally]
* link:#gkrcb[To List All Instances in a Domain]
* link:#gkqcw[To Delete an Instance Centrally]
* link:#gkqcj[To Start a Cluster]
* link:#gkqcl[To Stop a Cluster]
* link:#gkqaw[To Start an Individual Instance Centrally]
* link:#gkqaj[To Stop an Individual Instance Centrally]
* link:#gkqcc[To Restart an Individual Instance Centrally]

[[gkqch]][[GSHAG00106]][[to-create-an-instance-centrally]]

To Create an Instance Centrally
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Use the `create-instance` subcommand in remote mode to create a
GlassFish Server instance centrally. Creating an instance adds the
instance to the DAS configuration and creates the instance's files on
the host where the instance resides.

If the instance is a clustered instance that is managed by GMS, system
properties for the instance that relate to GMS must be configured
correctly. To avoid the need to restart the DAS and the instance,
configure an instance's system properties that relate to GMS when you
create the instance. If you change GMS-related system properties for an
existing instance, the DAS and the instance must be restarted to apply
the changes. For information about GMS, see
link:clusters.html#gjfnl[Group Management Service].

[[GSHAG380]]

Before You Begin

Ensure that following prerequisites are met:

* The node where the instance is to reside exists.
* The node where the instance is to reside is either enabled for remote
communication or represents the host on which the DAS is running. For
information about how to create a node that is enabled for remote
communication, see the following sections:

** link:nodes.html#CHDIGBJB[To Create a `DCOM` Node]

** link:nodes.html#gkrnf[To Create an `SSH` Node]
* The user of the DAS can use DCOM or SSH to log in to the host for the
node where the instance is to reside.

If any of these prerequisites is not met, create the instance locally as
explained in link:#gkqbl[To Create an Instance Locally].

If you are adding the instance to a cluster, ensure that the cluster to
which you are adding the instance exists. For information about how to
create a cluster, see link:clusters.html#gkqdm[To Create a Cluster].

If the instance is to reference an existing named configuration, ensure
that the configuration exists. For more information, see
link:named-configurations.html#abdjr[To Create a Named Configuration].

The instance might be a clustered instance that is managed by GMS and
resides on a node that represents a multihome host. In this situation,
ensure that you have the Internet Protocol (IP) address of the network
interface to which GMS binds.

1.  Ensure that the DAS is running. +
Remote subcommands require a running server.
2.  Run the `create-instance` subcommand. +

Administering GlassFish Server Instances Locally
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Local administration does not require DCOM or SSH to be set up. If
neither DCOM nor SSH is set up, you must log in to each host where
remote instances reside and administer the instances individually.

Administering GlassFish Server instances locally involves the following
tasks:

* link:#gkqbl[To Create an Instance Locally]
* link:#gkqed[To Delete an Instance Locally]
* link:#gkqak[To Start an Individual Instance Locally]
* link:#gkqci[To Stop an Individual Instance Locally]
* link:#gkqef[To Restart an Individual Instance Locally]


[width="100%",cols="<100%",]
|=======================================================================
a|
Note:

Even if neither DCOM nor SSH is set up, you can obtain information about
instances in a domain without logging in to each host where remote
instances reside. For instructions, see link:#gkrcb[To List All
Instances in a Domain].

|=======================================================================


[[gkqbl]][[GSHAG00114]][[to-create-an-instance-locally]]

To Create an Instance Locally
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Use the `create-local-instance` subcommand in remote mode to create a
GlassFish Server instance locally. Creating an instance adds the
instance to the DAS configuration and creates the instance's files on
the host where the instance resides.

If the instance is a clustered instance that is managed by GMS, system
properties for the instance that relate to GMS must be configured
correctly. To avoid the need to restart the DAS and the instance,
configure an instance's system properties that relate to GMS when you
create the instance. If you change GMS-related system properties for an
existing instance, the DAS and the instance must be restarted to apply
the changes. For information about GMS, see
link:clusters.html#gjfnl[Group Management Service].

[[GSHAG398]]

Before You Begin

If you plan to specify the node on which the instance is to reside,
ensure that the node exists.


[width="100%",cols="<100%",]
|=======================================================================
a|
Note:

If you create the instance on a host for which no nodes are defined, you
can create the instance without creating a node beforehand. In this
situation, GlassFish Server creates a `CONFIG` node for you. The name of
the node is the unqualified name of the host.

|=======================================================================


For information about how to create a node, see the following sections:

* link:nodes.html#CHDIGBJB[To Create a `DCOM` Node]
* link:nodes.html#gkrnf[To Create an `SSH` Node]
* link:nodes.html#gkrll[To Create a `CONFIG` Node]

If you are adding the instance to a cluster, ensure that the cluster to
which you are adding the instance exists. For information about how to
create a cluster, see link:clusters.html#gkqdm[To Create a Cluster].

If the instance is to reference an existing named configuration, ensure
that the configuration exists. For more information, see
link:named-configurations.html#abdjr[To Create a Named Configuration].

The instance might be a clustered instance that is managed by GMS and
resides on a node that represents a multihome host. In this situation,
ensure that you have the Internet Protocol (IP) address of the network
interface to which GMS binds.

1.  Ensure that the DAS is running. +

Resynchronizing GlassFish Server Instances and the DAS
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Configuration data for a GlassFish Server instance is stored as follows:

* In the repository of the domain administration server (DAS)
* In a cache on the host that is local to the instance

The configuration data in these locations must be synchronized. The
cache is synchronized in the following circumstances:

* Whenever an `asadmin` subcommand is run. For more information, see
"link:../administration-guide/overview.html#GSADG00697[Impact of Configuration Changes]" in GlassFish Server
Open Source Edition Administration Guide.
* When a user uses the administration tools to start or restart an
instance.

[[gksbo]][[GSHAG00267]][[default-synchronization-for-files-and-directories]]

Default Synchronization for Files and Directories
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The `--sync` option of the subcommands for starting an instance controls
the type of synchronization between the DAS and the instance's files
when the instance is started. You can use this option to override the
default synchronization behavior for the files and directories of an
instance. For more information, see link:#gksak[To Resynchronize an
Instance and the DAS Online].

On the DAS, the files and directories of an instance are stored in the
domain-dir directory, where domain-dir is the directory in which a
domain's configuration is stored. The default synchronization behavior
for the files and directories of an instance is as follows:

`applications`::
  This directory contains a subdirectory for each application that is
  deployed to the instance. +
  By default, only a change to an application's top-level directory
  within the application directory causes the DAS to synchronize that
  application's directory. When the DAS resynchronizes the
  `applications` directory, all the application's files and all
  generated content that is related to the application are copied to the
  instance. +
  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 and such files
  should not be changed by users. If an application is deployed and
  undeployed, full synchronization is not necessary to update the
  instance with the change.
`config`::
  This directory contains configuration files for the entire domain. +
  By default, the DAS resynchronizes files that have been modified since
  the last resynchronization only if the `domain.xml` file in this
  directory has been modified. +

[width="100%",cols="<100%",]
|=======================================================================
a|
Note:

If you add a file to the `config` directory of an instance, the file
is deleted when the instance is resynchronized with the DAS. However,
any file that you add to the `config` directory of the DAS is not
deleted when instances and the DAS are resynchronized. By default, any
file that you add to the `config` directory of the DAS is not
resynchronized. If you require any additional configuration files to
be resynchronized, you must specify the files explicitly. For more
information, see link:#gksaz[To Resynchronize Additional Configuration
Files].

|=======================================================================

`config`::
`config/`config-name::
  This directory contains files that are to be shared by all instances
  that reference the named configuration config-name. A config-name
  directory exists for each named configuration in the configuration of
  the DAS. +
  Because the config-name directory contains the subdirectories `lib`
  and `docroot`, this directory might be very large. Therefore, by
  default, only a change to a file or a top-level subdirectory of
  config-name causes the DAS to resynchronize the config-name directory.
`config/domain.xml`::
  This file contains the DAS configuration for the domain to which the
  instance belongs. +
  By default, the DAS resynchronizes this file if it has been modified
  since the last resynchronization. +

[width="100%",cols="<100%",]
|=======================================================================
a|
Note:

A change to the `config/domain.xml` file is required to cause the DAS
to resynchronize an instance's files. If the `config/domain.xml` file
has not changed since the last resynchronization, none of the
instance's files is resynchronized, even if some of these files are
out of date in the cache.

|=======================================================================

`docroot`::
  This directory is the HTTP document root directory. By default, all
  instances in a domain use the same document root directory. To enable
  instances to use a different document root directory, a virtual server
  must be created in which the `docroot` property is set. For more
  information, see the link:../reference-manual/create-virtual-server.html#GSRFM00062[`create-virtual-server`(1)] help
  page. +
  The `docroot` directory might be very large. Therefore, by default,
  only a change to a file or a subdirectory in the top level of the
  `docroot` directory causes the DAS to resynchronize the `docroot`
  directory. The DAS checks files in the top level of the `docroot`
  directory to ensure that changes to the `index.html` file are
  detected. +
  When the DAS resynchronizes the `docroot` directory, all modified
  files and subdirectories at any level are copied to the instance. +
  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.
`generated`::
  This directory contains generated files for Java EE applications and
  modules, for example, EJB stubs, compiled JSP classes, and security
  policy files. Do not modify the contents of this directory. +
  This directory is resynchronized when the `applications` directory is
  resynchronized. Therefore, only directories for applications that are
  deployed to the instance are resynchronized.
`java-web-start`::
  This directory is not resynchronized. It is created and populated as
  required on each instance.
`lib`::
`lib/classes`::
  These directories contain common Java class files or JAR archives and
  ZIP archives for use by applications that are deployed to the entire
  domain. Typically, these directories contain common JDBC drivers and
  other utility libraries that are shared by all applications in the
  domain. +
  The contents of these directories are loaded by the common class
  loader. For more information, see "link:../application-development-guide/class-loaders.html#GSDVG00342[Using the Common
  Class Loader]" in GlassFish Server Open Source Edition Application
  Development Guide. The class loader loads the contents of these
  directories in the following order: +
  1.  `lib/classes`
  2.  `lib/*.jar`
  3.  `lib/*.zip` +
  The `lib` directory also contains the following subdirectories: +
  `applibs`;;
    This directory contains application-specific Java class files or JAR
    archives and ZIP archives for use by applications that are deployed
    to the entire domain.
  `ext`;;
    This directory contains optional packages in JAR archives and ZIP
    archives for use by applications that are deployed to the entire
    domain. These archive files are loaded by using Java extension
    mechanism. For more information, see
    http://download.oracle.com/javase/6/docs/technotes/guides/extensions/extensions.html[Optional
    Packages - An Overview]
    (`http://docs.oracle.com/javase/7/docs/technotes/guides/extensions/extensions.html`). +

[width="100%",cols="<100%",]
|=======================================================================
a|
Note:

Optional packages were formerly known as standard extensions or
extensions.

|=======================================================================

  The `lib` directory and its subdirectories typically contain only a
  small number of files. Therefore, by default, a change to any file in
  these directories causes the DAS to resynchronize the file that
  changed.

Example 5-16 Resynchronizing an Instance and the DAS Online

This example determines that the instance `yml-i1` is stopped and fully
resynchronizes the instance with the DAS. Because neither DCOM nor SSH
is set up, the instance is started locally on the host where the
instance resides. In this example, multiple nodes are defined for the
GlassFish Server installation that is running on the node's host.

To determine whether the instance is stopped, the following command is
run in multimode on the DAS host:

[source,oac_no_warn]
----
asadmin> list-instances yml-i1
yml-i1   not running
Command list-instances executed successfully.
----

To start the instance, the following command is run in single mode on
the host where the instance resides:

[source,oac_no_warn]
----
$ asadmin start-local-instance --node sj01 --sync full yml-i1
Removing all cached state for instance yml-i1.

To Resynchronize Users' Changes to Files
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

A change to the `config/domain.xml` file is required to cause the DAS to
resynchronize instances' files. If other files in the domain directory
are changed without a change to the `config/domain.xml` file, instances
are not resynchronized with these changes.

The following changes are examples of changes to the domain directory
without a change to the `config/domain.xml` file:

* Adding files to the `lib` directory
* Adding certificates to the key store by using the `keytool` command

1.  Change the last modified time of the `config/domain.xml` file. +
Exactly how to change the last modified time depends on the operating
system. For example, on UNIX and Linux systems, you can use the
http://www.oracle.com/pls/topic/lookup?ctx=E18752&id=REFMAN1touch-1[`touch`(1)]
command.

By default, GlassFish Server synchronizes only the following
configuration files:

* `admin-keyfile`
* `cacerts.jks`
* `default-web.xml`
* `domain.xml`
* `domain-passwords`
* `keyfile`
* `keystore.jks`
* `server.policy`
* `sun-acc.xml`
* `wss-server-config-1.0`
* `xml wss-server-config-2.0.xml`

If you require instances in a domain to be resynchronized with
additional configuration files for the domain, you can specify a list of
files to resynchronize.


[width="100%",cols="<100%",]
|=======================================================================
a|
Caution:

If you specify a list of files to resynchronize, you must specify all
the files that the instances require, including the files that GlassFish
Server resynchronizes by default. Any file in the instance's cache that
is not in the list is deleted when the instance is resynchronized with
the DAS.

|=======================================================================


In the `config` directory of the domain, create a plain text file that
is named `config-files` that lists the files to resynchronize.

In the `config-files` file, list each file name on a separate line.

To Prevent Deletion of Application-Generated Files
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

When the DAS resynchronizes an instance's files, the DAS deletes from
the instance's cache any files that are not listed for
resynchronization. If an application creates files in a directory that
the DAS resynchronizes, these files are deleted when the DAS
resynchronizes an instance with the DAS.

Put the files in a subdirectory under the domain directory that is not
defined by GlassFish Server, for example,
`/export/glassfish3/glassfish/domains/domain1/myapp/myfile`.

Resynchronizing an instance and the DAS offline updates the instance's
cache without the need for the instance to be able to communicate with
the DAS. Offline resynchronization is typically required for the
following reasons:

* To reestablish the instance after an upgrade
* To synchronize the instance manually with the DAS when the instance

Migrating EJB Timers
~~~~~~~~~~~~~~~~~~~~

If a GlassFish Server server instance stops or fails abnormally, it may
be desirable to migrate the EJB timers defined for that stopped server
instance to another running server instance.

Automatic timer migration is enabled by default for clustered server
instances that are stopped normally. Automatic timer migration can also
be enabled to handle clustered server instance crashes. In addition,
timers can be migrated manually for stopped or crashed server instances.

* link:#gkvwo[To Enable Automatic EJB Timer Migration for Failed
Clustered Instances]
* link:#abdji[To Migrate EJB Timers Manually]

[[gkvwo]][[GSHAG00126]][[to-enable-automatic-ejb-timer-migration-for-failed-clustered-instances]]

To Enable Automatic EJB Timer Migration for Failed Clustered Instances
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Automatic migration of EJB timers is enabled by default for clustered
server instances that are stopped normally. If the Group Management
Service (GMS) is enabled and a clustered instance is stopped normally,
no further action is required for timer migration to occur. The
procedure in this section is only necessary if you want to enable
automatic timer migration for clustered server instances that have
stopped abnormally.


[width="100%",cols="<100%",]
|=======================================================================
a|
Note:

If the GMS is enabled, the default automatic timer migration cannot be
disabled. To disable automatic timer migration, you must first disable
the GMS. For information about the GMS, see
link:clusters.html#gjfnl[Group Management Service].

|=======================================================================


[[GSHAG415]]

Before You Begin

Automatic EJB timer migration can only be configured for clustered
server instances. Automatic timer migration is not possible for
standalone server instances.

Enable delegated transaction recovery for the cluster.

This enables automatic timer migration for failed server instances in
the cluster.

For instructions on enabling delegated transaction recovery, see
"link:../administration-guide/transactions.html#GSADG00022[Administering Transactions]" in GlassFish Server Open
Source Edition Administration Guide.

[[abdji]][[GSHAG00127]][[to-migrate-ejb-timers-manually]]

To Migrate EJB Timers Manually
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

EJB timers can be migrated manually from a stopped source instance to a
specified target instance in the same cluster if GMS notification is not
enabled. If no target instance is specified, the DAS will attempt to
find a suitable server instance. A migration notification will then be
sent to the selected target server instance.

Note the following restrictions:

* If the source instance is part of a cluster, then the target instance
must also be part of that same cluster.
* It is not possible to migrate timers from a standalone instance to a
clustered instance, or from one cluster to another cluster.
* It is not possible to migrate timers from one standalone instance to
another standalone instance.
* All EJB timers defined for a given instance are migrated with this
procedure. It is not possible to migrate individual timers.

[[GSHAG416]]

Before You Begin

The server instance from which the EJB timers are to be migrated should
not be active during the migration process.
