一个重要的优势在于，它能够配置具有较少物理内存的系统。
One of the key benefits is that it provides the ability to configure systems with less physical memory.
在默认情况下，系统并不为大页面物理内存池分配任何内存。
By default, the system does not allocate any memory to the large page physical memory pool.
由于缺乏为进程定义内存的能力，底层物理内存被过度使用。
Having the ability to sparsely define memory for processes means that the underlying physical memory can be overcommitted.
如果这会显著影响性能，可能应该考虑在池中增加更多物理内存。
If this impacts performance dramatically, it's probably time to add more physical memory to the pool.
开发人员没有检测到这个问题，因为他们的机器有更多的物理内存。
The developers hadn't detected the problem because their machines had more physical memory.
整个物理内存被划分为若干块，这些块称为物理内存块(PMB)。
The whole physical memory is divided into blocks called physical memory blocks (PMB).
映射给客户操作系统的物理内存实际上是映射给这个进程的虚拟内存。
The physical memory that is mapped for the guest operating system is actually virtual memory mapped into the process.
在给定的时刻，“正在使用的”逻辑内存量等于池中的物理内存量。
The logical memory "in use" at a given time is equal to the physical memory in the pool.
消息流程的工作集可能很大，因此，所需的物理内存的数量也可能很大。
The working set of message flows can be substantial and, consequently, so might the amount of physical memory that is required.
我将介绍AIX如何使用虚拟内存来寻址比系统中物理内存更大的内存。
I discuss how AIX USES virtual memory to address more memory than is physically on your system.
因此，增加内存时获得的性能提升源于物理内存的改变，而非其他东西。
Therefore, any throughput gains that occurred when we increased the memory were the result of changes in physical memory and not something else.
存储为大页面的应用程序数据会一直留在物理内存中，直到应用程序终止。
The data of an application that is backed by large pages remains in physical memory until the application completes.
大型物理内存能够改进数据库的可伸缩性，因此最好使用一个64位实例。
Larger physical memory improves the scalability of the database, so using a 64-bit instance is preferable.
系统现在可以全部装入物理内存，而不必借助慢速的基于磁盘的交换空间。
The system is able to fit everything into physical memory without having to resort to slow, disk-based swap space.
将包含该分页的物理内存块标记为空闲，并为其它的分页做好重用的准备。
The physical memory block that contains the page is marked as free and ready for reuse for additional pages.
在这种情况下，所有LPAR的工作集内存需求可以超过池中的物理内存量。
In this scenario, the working set memory requirements of all LPARs can exceed the physical memory in the pool.
结果是您很可能会增加JVM大小(假设您有足够的物理内存用于JVM)。
As a result, you're likely to increase the size of the JVM (assuming you have adequate physical memory for the JVM).
我们将介绍AIX7如何使用虚拟内存来寻址比系统物理内存更大的内存。
We discuss how AIX 7 USES virtual memory to address more memory than is physically on your system.
与其他风格的UNIX一样，AIX也使用虚拟内存结构帮助补充物理内存。
Just like with other forms of UNIX, AIX employs virtual memory structures to help complement physical memory.
答案跟可寻址内存(而不是物理内存)的限制有关，我们在后面会加以讨论。
The answer to this question has to do with the limitation to the addressable memory (as opposed to physical memory), which we will discuss later.
这样的话，如果没有内存争用，一个WPAR可以使用系统的所有物理内存。
In that way, a WPAR would be able to use all of system's physical memory if there was no contention for memory.
从本质上说，任何不会达到其物理内存消耗上限的工作负载都适合配置ams。
Essentially, any workload that is not maximizing its physical memory consumption is an excellent candidate for AMS.
