## delete-jvm-options

removes one or more options for the Java application launcher

Synopsis

    delete-jvm-options [--help] [--target target] [--profiler={true|false}]
    (jvm-option-name[=jvm-option-value]) [:jvm-option-name[=jvm-option-name]]*

Description

The `delete-jvm-options` subcommand removes one or more command-line options for the Java application launcher. These options are removed from the Java configuration `java—config` element or the profiler `profiler` element of the `domain.xml` file. To see the Java application launcher options that can be deleted, use the list-jvm-options(1) subcommand.

The deletion of some options requires a server restart for changes to become effective. Other options are set immediately in the environment of the domain administration server (DAS) and do not require a restart.

Whether a restart is required depends on the type of option.

- Restart is not required for Java system properties whose names do not start with `-Djava.` or `-Djavax.` (including the trailing period). For example, restart is not required for the following Java system property:

  `-Denvironment=Production`

- Restart is required for the following options:

  - Java system properties whose names start with `-Djava.` or `-Djavax.` (including the trailing period). For example:

    `-Djava.security.manager`

  - Startup parameters for the Java application launcher. For example:

    `-client`

    `-Xmx1024m`

    `-d64`

To restart the DAS, use the restart-domain(1) command.

This subcommand is supported in remote mode only.

Options

`--help`
`-?`

  Displays the help text for the subcommand.

`--target`

  Specifies the target from which you are removing Java application launcher options.

  Valid values are as follows:

  `server`

    Specifies the DAS (default).

  instance-name

    Specifies a GlassFish Server instance.

  cluster-name

    Specifies a cluster.

  configuration-name

    Specifies a named configuration.

`--profiler`

  Indicates whether the Java application launcher options are for the profiler. The option must have been set for a profiler for this option to be true.

Operands

jvm-option-name

  One or more options delimited by a colon (:). The format of the operand depends on the following:

  - If the option has a name and a value, the format is option-name=value.

  - If the option has only a name, the format is option-name. For example, `-Xmx2048m`.

  Note:

  If an option name or option value contains a colon, the backslash (`\`) must be used to escape the colon in the name or value. Other characters might also require an escape character. For more information about escape characters in subcommand options, see the asadmin(1M) man page.

Example 2 Deleting a Java Application Launcher Option From the Profiler

  This example removes a Java application launcher startup parameter for the profiler.
