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.
