提供的全局值是否正确？
步骤1：计算全局值。
WebSpherePortal如何提供缓存信息的全局值？
How WebSphere Portal contributes global values of cache information?
举例来说，我通常会在根元素的属性中包含重要的全局值。
For instance, I often put important global values in attributes on my root element. To make these values globally available in my code, I store them in top-level variables before using them.
您在environments块中设置的值将覆盖全局值。
Values that you set in the environments block will override the global values.
WebSpherePortal中有三个影响与远程缓存中的缓存相关的全局值的全局设置。
There are three global Settings in WebSphere Portal which influence global values relevant for caching in remote caches.
首先，声明一个任何探针都可以使用的全局值(全局名称空间对所有探针都是通用的)，然后将它初始化为0。
First, declare a global value that any probe can use (the global namespace is common to all probes), then initialize it to zero.
但是此时，我们不能计算工作项的状态，因为它可能包含了子工作项，这样我们需要声明两个全局变量，以存储这些值。
But at this moment we cannot calculate the work item status because it may contain sub-work items, so we need to declare two global variables to store these values.
此方法将从全局上下文中获得一个值。
如上文所述，每个会话对于给定的全局变量都具有自己的私有值。
As mentioned before, each session has its own private value of a given global variable.
此外，您不能更改全局变量定义，包括其默认值。
Furthermore, you cannot ALTER the global variable definition at all, including its default value.
使用事件处理程序的索引来从全局输入列表中选择输入值。
Use the event handler’s index to select the input out of the global input list.
全局缺省值的设置与算法将在下文中予以说明。
The Settings and algorithms around global default values are explained later.
全局上下文支持值路径，它直接访问某个对象类型。
The global context supports value pathing, which is direct access into certain object types.
视图可以在谓词中使用该全局变量的值，从而只选择分配给用户所在部门的行。
A view could use the value of this global variable in a predicate to select only those rows for which the user's department is assigned.
然而，更好的方法是使测试类能够直接给方法传入这些全局变量的值。
However, a better approach is to provide a way for the tester class to directly pass in values for these globals that the method can use.
请求验证与否可能会影响全局缺省值。
Global default values may vary upon whether a request is authenticated or not.
在默认小节中，修改希望全局实现的属性的默认值。
In the defaults stanza section, change the default value of the attribute you wish to implement globally, as summarized in the previous section.
在出现问题时，opendir()和readdir()函数都会返回NULL，并且将设置全局变量 errno 的值，以指出所出现的错误。
The opendir() and readdir() functions both return NULL if a problem occurs and the errno global variable is set to indicate what went wrong.
然后，在Actions选项卡上，设置一个全局变量，将它的值设为CICS，然后应用您创建的CICSScreens转换，如图23所示。
Then, on the Actions TAB, set a global variable to CICS and apply the CICSScreens transformation you created, as in Figure 23.
而且，还有一个相关的全局属性值，可以全面开启和关闭并行Portlet呈现功能。
On top of that, there is a global property value that generally turns parallel portlet rendering on and off.
之后，如果需要对表执行任何维护，您所需做的就是修改会话中全局变量的值
Then whenever you want to perform any maintenance in this table, all you have to do is modify the value of the global variable in this session
如果组件不提供任何此类信息，WebSpherePortal将依赖于每个组件的全局缺省值。
In case the components do not provide any of this information, WebSphere Portal relies on global default values for each of the components.
只要Porlet、门户页面或Theme未提供任何缓存信息，就将使用全局缺省值。
Global default values are used whenever a portlet, a portal page, or a theme does not contribute any cache information.
因此，应用程序无法回滚全局变量的值设置。
Hence, an application cannot roll back the setting of the value of a global variable. Note the following.
可以使用SET,SELECTINTO,VALUESinto语句改变全局变量的值。
The value of a global variable can be changed using the SET, SELECT INTO, VALUES INTO statements.
编译器选择的默认评估值是用在特殊注册、全局变量或参数标记的。
The default estimates chosen by the compiler are used for the special registers, global variables, or parameter markers.
检查全局缺省值和全局最大值中说明的算法。
Check the algorithm as explained in global default values and global maximum values.
请参阅全局缺省值与全局最大值，以了解这些值的计算方式及其所基于的设置。
See global default values and global maximum values to find out how these values are calculated and what they are based upon.
服务可以覆盖这些全局默认值。
These global defaults can be overridden by an individual service.
