set

sets the values of configurable attributes

Synopsis

set [--help] attribute-name=value

Description

The set subcommand uses dotted names to modify the values of one or more configurable attributes.

Attributes from the monitoring hierarchy are read-only, but configuration attributes can be modified. You can use the list(1) subcommand to display the dotted names that represent individual server components and subsystems. For example, a dotted name might be server.applications.web-module. After you discover the particular component or subsystem, you can then use the get subcommand to access the attributes. For more detailed information on dotted names, see the dotted-names(5ASC) help page.

Note:

Characters that have special meaning to the shell or command interpreter, such as * (asterisk), should be quoted or escaped as appropriate to the shell, for example, by enclosing the argument in quotes. In multimode, quotes are needed only for arguments that include spaces, quotes, or backslash.

By modifying attributes, you can enable and disable services, and customize how an existing element functions. An asadmin subcommand is provided to update some elements. For example, update-password-alias. However, to update other elements, you must use the set command. For example, you create a JDBC connection pool by using the create-jdbc-connection-pool subcommand. To change attribute settings later, you use the set command.

Any change made by using the asadmin utility subcommands or the Administration Console are automatically applied to the associated GlassFish Server configuration file.

Options

--help
-?: Displays the help text for the subcommand.

Operands

attribute-name=value: Identifies the full dotted name of the attribute name and its value.
