Administering System Properties

Shared server instances will often need to override attributes defined in their referenced configuration. Any configuration attribute can be overridden through a system property of the corresponding name.

The following topics are addressed here:

• To Create System Properties

• To List System Properties

• To Delete a System Property

To Create System Properties

Use the create-system-properties subcommand in remote mode to create or update one or more system properties of the domain or configuration. Any configuration attribute can be overwritten through a system property of the corresponding name.

1. Ensure that the server is running.

   Remote subcommands require a running server.

2. Create system properties by using the create-system-properties(1) subcommand.

   Information about properties for the subcommand is included in this help page.

Example 2–10 Creating a System Property

This example creates a system property associated with http-listener-port=1088 on localhost.

asadmin> create-system-properties http-listener-port=1088
Command create-system-properties executed successfully.

You can also view the full syntax and options of the subcommand by typing asadmin help create-system-properties at the command line.

To List System Properties

Use the list-system-properties subcommand in remote mode to list the system properties that apply to a domain or configuration.

1. Ensure that the server is running.

   Remote subcommands require a running server.

2. List system properties by using the list-system-properties(1) subcommand.

   The existing system properties are displayed, including predefined properties such as HTTP_LISTENER_PORT and HTTP_SSL_LISTENER_PORT.

Example 2–11 Listing System Properties

This example lists the system properties on host localhost.

asadmin> list-system-properties
http-listener-port=1088
Command list-system-properties executed successfully.

You can also view the full syntax and options of the subcommand by typing asadmin help list-system-properties at the command line.

To Delete a System Property

Use the delete-system-property subcommand in remote mode to delete system properties.

1. Ensure that the server is running.

   Remote subcommands require a running server.

2. List the existing system properties by using the list-system-properties(1) subcommand.

3. Delete the system property by using the delete-system-property(1) subcommand.

4. If necessary, notify users that the system property has been deleted.

Example 2–12 Deleting a System Property

This example deletes a system property named http-listener-port from localhost.

asadmin> delete-system-property http-listener-port
Command delete-system-property executed successfully.
