Description

The list-jvm-options command displays a list of command-line options that are passed to the Java application launcher when the Enterprise Server is started. The list-jvm-options command displays the following options:

• Java system properties. System properties are set through the -D option of the Java application launcher, for example:

  • -Djava.security.manager

  • -Denvironment=Production

• Startup parameters for the Virtual Machine for the Java platform (Java Virtual Machine or JVM machine). [The terms "Java Virtual Machine" and "JVM" mean a Virtual Machine for the Java platform.] Startup parameters are preceded by the dash character (-) , for example:

  • --XX:PermSize=size

  • -Xmx1024m

  • -client

  • -d64

The options are specified through the JVM Options page of the Administration Console or through the following commands:

• create-jvm-options(1)

• delete-jvm-options(1)

This command is supported in remote mode only.

For more information about the Java application launcher, see the reference page for the operating system that you are using:

• Solaris Operating System (Solaris OS) and Linux: java - the Java application launcher

• Windows: java - the Java application launcher

Options

-t --terse

Indicates that any output data must be very concise, typically avoiding human-friendly sentences and favoring well-formatted data for consumption by a script. Default is false.

-e --echo

If set to true, the command-line statement is echoed on the standard output. Default is false.

-I --interactive

If set to true (default), only the required password options are prompted.

-H --host

The machine name where the domain administration server is running. The default value is localhost.

-p --port

The HTTP port or HTTPS port for administration. This port is the port in the URL that you specify in your web browser to manage the domain, for example, http://localhost:4848.

The default port number for administration is 4848.

-s --secure

If set to true, uses SSL/TLS to communicate with the domain administration server.

The default is false.

-u --user

The user name of the authorized administrative user of the domain administration server.

If you have authenticated to a domain by using the asadmin login command, you need not specify the --user option for subsequent operations on the domain.

--passwordfile

Specifies the name, including the full path, of a file that contains the password entries in a specific format.

The entry for a password must have the AS_ADMIN_ prefix followed by the password name in uppercase letters. For example, to specify the password for the domain administration server, use an entry with the following format:

AS_ADMIN_PASSWORD=password

In this example, password is the actual administrator password.

The following other passwords can also be specified:

• AS_ADMIN_MAPPEDPASSWORD

• AS_ADMIN_USERPASSWORD

• AS_ADMIN_ALIASPASSWORD

All remote commands must specify the administration password to authenticate to the domain administration server. The password can be specified by one of the following means:

• Through the --passwordfile option

• Through the asadmin login command

• Interactively at the command prompt

The asadmin login command can be used only to specify the administration password. For other passwords that remote commands require, use the --passwordfile option or specify them at the command prompt.

After authenticating to a domain by using the asadmin login command, you need not specify the administration password through the --passwordfile option for subsequent operations on the domain. However, only the AS_ADMIN_PASSWORD option is not required. You still must provide the other passwords, for example, AS_ADMIN_USERPASSWORD, when required by individual commands, such as update-file-user.

For security reasons, a password that is specified as an environment variable is not read by the asadmin command.

The default value for AS_ADMIN_MASTERPASSWORD is changeit.

--help

Displays the help text for the command.
