configuration - IBM WebSphere 应用服务器 : What are "environment entries" for?

Question

在 WebSphere Application Server 管理控制台中，下面有一个部分
应用服务器 > server1 > 流程定义 > 环境条目

我不明白环境条目是什么。它们不是系统属性，因为它们是在进程定义 > Java 虚拟机 > 自定义属性中定义的。

那是什么？如何从应用程序中访问它们。

报价http://www-01.ibm.com/support/docview.wss?uid=swg21254153 ，官方描述是；

Environment entries can be used to specify variables not specific to WebSphere Application Server, but are defined by other elements, such as UNIX®, Language Environment® (LE), or third-party vendors, among others. These variables tend to be operating system-specific.

所以它们是特定于操作系统的(即 Windows 的 PATH，AIX 的 LIBPATH，Solaris 的 LD_LIBRARY_PATH)。

对于需要使用的示例案例；引用 http://publib.boulder.ibm.com/infocenter/dmndhelp/v7r0mx/topic/com.ibm.wbit.help.runtime.doc/deploy/topics/rcfglibadapters.html

If a native library is dependent on other native libraries, the dependent libraries must be configured on the LIBPATH of the JVM hosting the application server (rather than on the native path shown in the above figure) in order for that library to load successfully. You should configure an environment entry by selecting Servers > Application Servers > server_name > Java and Process Management > Process Definition > Environment Entries (where server_name is the name of the server; for example, server1). On the Environment Entries page, create a new environment entry to specify the LIBPATH of the JVM.

您可以使用 System.getenv()(不是 System.getProperties()，它返回自定义属性和通用 JVM 参数)访问这些变量。
