Description

The create-local-instance subcommand creates a \{product---name} instance on the node that represents the host where the subcommand is run. This subcommand does not require the Distributed Component Object Model (DCOM) remote protocol or secure shell (SSH) to be configured.

You must run this subcommand from the host that is represented by the node where the instance is to reside. To contact the domain administration server (DAS), this subcommand requires the name of the host where the DAS is running. If a nondefault port is used for administration, this subcommand also requires the port number. If you are adding the first instance to a node, you must provide this information through the --host option and the --port option of the asadmin(1M) utility. For the second and later instances, this information is obtained from the DAS properties of the node.

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

A \{product---name} instance requires a reference to the following items:

  • The node that defines the host where the instance resides. The node can be specified in the command to create the instance, but is required only if more than one node exists in the directory where files for nodes are stored. If no node is specified, the behavior of the subcommand depends on the number of existing nodes in the directory where nodes are stored:

    • If no nodes exist, the subcommand creates a node for the instance. The name of the node is the name of the host on which the subcommand is run.

    • If only one node exists, the subcommand creates a reference to the existing node for the instance.

    • If two or more nodes exist, an error occurs.

  • The named configuration that defines the configuration of the instance. The configuration can be specified in the command to create the instance, but is not required. If no configuration is specified for an instance that is not joining a cluster, the subcommand creates a configuration for the instance. An instance that is joining a cluster receives its configuration from its parent cluster.

Each \{product---name} 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.

By default, this subcommand attempts to resolve possible port conflicts for the instance that is being created. The subcommand also assigns ports that are currently not in use and not already assigned to other instances on the same node. The subcommand assigns these ports on the basis of an algorithm that is internal to the subcommand. Use the --systemproperties option to resolve port conflicts for additional instances on the same node. System properties of an instance can be manipulated by using the create-system-properties(1) subcommand and the delete-system-property(1) subcommand.

When creating an instance, the subcommand retrieves the files that are required for secure synchronization with the domain administration server (DAS). The instance is synchronized with the DAS when the instance is started

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.

--node

The name of the node that defines the host where the instance is to be created. The node must be specified only if more than one node exists in the directory where nodes are stored. Otherwise, the node may be omitted. If a node is specified, the node must exist.
If no node is specified, the behavior of the subcommand depends on the number of existing nodes in the directory where nodes are stored:

  • If no nodes exist, the subcommand creates a node for the instance. The name of the node is the name of the host on which the subcommand is run.

  • If only one node exists, the subcommand creates a reference to the existing node for the instance.

  • If two or more nodes exist, an error occurs.

--nodedir

The path to the directory in which the files for instance’s node is to be stored. The default is as-install`/nodes`.

--config

Specifies the named configuration that the instance references. The configuration must exist and must not be named default-config or server-config. Specifying the --config option creates a shared instance.
The --config option and the --cluster option are mutually exclusive. If both options are omitted, a standalone instance is created.

--cluster

Specifies the cluster from which the instance inherits its configuration. Specifying the --cluster option creates a clustered instance.
The --config option and the --cluster option are mutually exclusive. If both options are omitted, a standalone instance is created.

--lbenabled

Specifies whether the instance is enabled for load balancing. Possible values are as follows:

true

The instance is enabled for load balancing (default).
When an instance is enabled for load balancing, a load balancer sends requests to the instance.

false

The instance is disabled for load balancing.
When an instance is disabled for load balancing, a load balancer does not send requests to the instance.

--portbase

Determines the number with which the port assignment should start. An instance uses a certain number of ports that are statically assigned. The portbase value determines where the assignment should start. The values for the ports are calculated as follows:

  • Administration port: portbase + 48

  • HTTP listener port: portbase + 80

  • HTTPS listener port: portbase + 81

  • JMS port: portbase + 76

  • IIOP listener port: portbase + 37

  • Secure IIOP listener port: portbase + 38

  • Secure IIOP with mutual authentication port: portbase + 39

  • JMX port: portbase + 86

  • JPA debugger port: portbase + 9

  • Felix shell service port for OSGi module management: portbase + 66
    When the --portbase option is specified, the output of this subcommand includes a complete list of used ports.

--checkports

Specifies whether to check for the availability of the administration, HTTP, JMS, JMX, and IIOP ports. The default value is true.

--savemasterpassword

Setting this option to true allows the master password to be written to the file system. If the master password is written to the file system, the instance can be started without the need to prompt for the password. If this option is true, the --usemasterpassword option is also true, regardless of the value that is specified on the command line. Because writing the master password to the file system is an insecure practice, the default is false.
The master-password file for an instance is saved in the node directory, not the domain directory. Therefore, this option is required only for the first instance that is created for each node in a domain.

--usemasterpassword

Specifies whether the key store is encrypted with a master password that is built into the system or a user-defined master password.
If false (default), the keystore is encrypted with a well-known password that is built into the system. Encrypting the keystore with a password that is built into the system provides no additional security.
If true, the subcommand obtains the master password from the AS_ADMIN_MASTERPASSWORD entry in the password file or prompts for the master password. The password file is specified in the --passwordfile option of the asadmin(1M)utility.
If the --savemasterpassword option is true, this option is also true, regardless of the value that is specified on the command line.
The master password must be the same for all instances in a domain.

--systemproperties

Defines system properties for the instance. These properties override property definitions for port settings in the instance’s configuration. Predefined port settings must be overridden if, for example, two clustered instances reside on the same host. In this situation, port settings for one instance must be overridden because both instances share the same configuration.
The following properties are available:

ASADMIN_LISTENER_PORT

This property specifies the port number of the HTTP port or HTTPS port through which the DAS connects to the instance to manage the instance. Valid values are 1-65535. On UNIX, creating sockets that listen on ports 1-1024 requires superuser privileges.

HTTP_LISTENER_PORT

This property specifies the port number of the port that is used to listen for HTTP requests. Valid values are 1-65535. On UNIX, creating sockets that listen on ports 1-1024 requires superuser privileges.

HTTP_SSL_LISTENER_PORT

This property specifies the port number of the port that is used to listen for HTTPS requests. Valid values are 1-65535. On UNIX, creating sockets that listen on ports 1-1024 requires superuser privileges.

IIOP_LISTENER_PORT

This property specifies the port number of the port that is used for IIOP connections. Valid values are 1-65535. On UNIX, creating sockets that listen on ports 1-1024 requires superuser privileges.

IIOP_SSL_LISTENER_PORT

This property specifies the port number of the port that is used for secure IIOP connections. Valid values are 1-65535. On UNIX, creating sockets that listen on ports 1-1024 requires superuser privileges.

IIOP_SSL_MUTUALAUTH_PORT

This property specifies the port number of the port that is used for secure IIOP connections with client authentication. Valid values are 1-65535. On UNIX, creating sockets that listen on ports 1-1024 requires superuser privileges.

JAVA_DEBUGGER_PORT

This property specifies the port number of the port that is used for connections to the Java Platform Debugger Architecture (JPDA) (http://www.oracle.com/technetwork/java/javase/tech/jpda-141715.html) debugger. Valid values are 1-65535. On UNIX, creating sockets that listen on ports 1-1024 requires superuser privileges.

JMS_PROVIDER_PORT

This property specifies the port number for the Java Message Service provider. Valid values are 1-65535. On UNIX, creating sockets that listen on ports 1-1024 requires superuser privileges.

JMX_SYSTEM_CONNECTOR_PORT

This property specifies the port number on which the JMX connector listens. Valid values are 1-65535. On UNIX, creating sockets that listen on ports 1-1024 requires superuser privileges.

OSGI_SHELL_TELNET_PORT

Example 2   Creating a Clustered \{product---name} Instance on a Specific Node

This example creates the clustered instance ymli2 on node sj02. The instance is a member of the cluster ymlclust.

The command is run on the host sj02, which is the host that the node sj02 represents. The DAS is running on the host sr04 and uses the default HTTP port for administration. Because no instances exist on the node, the host on which the DAS is running is provided through the --host option of the asadmin utility.
