Administer the Liberty profile manually

Overview

server.xml is the primary configuration file.

bootstrap.properties specifies properties that need to be available before the primary configuration is processed. If updated, restart the server with the --clean option for the changes to take effect.

Administer

7. Configure session persistence for the Liberty profile
   
8. Connect to the Liberty profile using JMX

Example

However, the only required configuration element in server.xml is a server definition:

<server/>

Beyond this server definition, you only specify overrides and additions to the default configuration values. For example, to change the transaction timeout value, we specify:

<transactions timeout="30" />

Some attributes can have multiple values. For example, you use a list of values to define the features that are to be provided by the server:

server     < featureManager>
        <feature>servlet-3.0</feature>         <feature>localConnector-1.0</feature>     </featureManager> </server>

See also Add and remove Liberty features.

Where multiple instances of a resource type can be configured, for example applications or data sources, you need only provide the attributes that are unique for the resource. We can let the other attributes use the default values, or override them as needed. Therefore the contents of server.xml can be brief. For example, here is a complete server configuration to run a web application:

server      < featureManager>
         <feature>servlet_3.0</feature>      </featureManager>      <application name="snoop" location="/mywebapps/snoop"war"/> </server>
