Setting custom properties in the WebSphere Application Server Liberty profile

Question & Answer


How do I configure custom properties for the WebSphere Application Server Liberty profile?


There are many custom properties available for the WebSphere Application Server Liberty profile. The elements, attributes and sub-elements that can be configured are available in IBM Documentation pages, in Server configuration you can find any element in table of contents at your left.

If you are working with IBM Support, or resolving an issue independently through the IBM Support Portal, you might also be asked to set a custom property.

WebSphere custom properties for the Liberty profile are set in the server.xml file of the application server.

Note: For the default server instance, the server.xml file is located in the following location:

<liberty install root>/usr/servers/defaultServer/server.xml

For example: To configure the deferServletLoad web container custom property

Description: Defer servlet load and initialization until first request
Data type: boolean
Default value: true
Required: false

Add the following line to the server.xml configuration file:

<webContainer deferServletLoad="false"/>

Note: To configure a Java Virtual Machine custom property, set the property in the jvm.options file.

Customizing the Liberty environment

The server management script searches for jvm.options in two locations: ${wlp.install.dir}/etc/jvm.options and ${server.config.dir}/jvm.options. If both files are present, the options in the ${server.config.dir}/jvm.options file are used.
