- the data set that determines how GlassFish Server operates
The configuration of GlassFish Server is the data set that determines how it operates. Parts of this configuration determine the operation of specific parts of GlassFish Server, such as the following:
Services, such as the transaction service
Resources, such as databases
Deployed applications or modules, such as web applications
Clusters and server instances
The term configuration is also used to describe a part of the overall configuration, such as the transaction service configuration or the configuration of a database. In clustered environments, clusters or server instances can share configurations.
Examples of configuration data are port numbers, flags that enable or disable processes, application names, and so on. Most of these data points are name/value pairs, either hard-coded attributes or more flexibly defined properties.
The hierarchical structure of the configuration is explained in the dotted names page. You can view and change most of the GlassFish Server configuration using either the Administration Console or the asadmin utility and its subcommands. To list the structure of all or part of the configuration, use the list subcommand. To view the value of one or more attributes or properties, use the get subcommand. To change the value of an attribute or property, use the set subcommand.
