我在 OpenLiberty 18.0.0.2 中找不到任何關于嵌入式數據庫的文檔，例如 Payara 或 Wildfly。默認情況下是否有隨 OpenLiberty 一起提供的嵌入式數據庫，還是我必須自己配置 H2 或 Derby DB？現在我正在配置一個 Derby DB，如下所示：<?xml version="1.0" encoding="UTF-8"?><server description="new server">  <featureManager>    <feature>javaee-8.0</feature>  </featureManager>  <quickStartSecurity userName="admin" userPassword="adminpwd" />  <httpEndpoint id="defaultHttpEndpoint" httpPort="9080" httpsPort="9443" />  <applicationManager autoExpand="true" />  <applicationMonitor updateTrigger="mbean" />      <dataSource id="DefaultDataSource">    <jdbcDriver libraryRef="MyJDBCLib" />    <properties.derby.embedded databaseName="myDB" createDatabase="create" />    <containerAuthData user="user1" password="{xor}Oz0vKDtu" />  </dataSource>  <library id="MyJDBCLib">    <file name="/Users/Philip/Tools/openliberty/wlp-18.0.0.2/lib/derby.jar" />  </library></server>這是 OpenLiberty 的正確/常見方法嗎？
