Specifying Liberty profile bootstrap properties

Bootstrap properties initialize the runtime environment for a particular server. Generally, they are attributes that affect the configuration and initialization of the runtime core.

About this task

Bootstrap properties are set in a text file named bootstrap.properties. This file is not required, so it does not exist unless you create it. You must create this file in the server directory, which also contains the configuration root file server.xml. By default, the server directory is usr/servers/server_name. You can change the server directory as described in Fix Pack 8501 Customizing the Liberty profile environment.

The bootstrap.properties file contains two types of properties:
  • A small, predefined set of initialization properties.
  • Any custom properties that you choose to define. You can then use these custom properties as variables in other configuration files such as server.xml and included files.

If you update the bootstrap.properties file, you must restart the server for the changes to take effect.
