The following REORG example reorganizes the customer table using the system temporary tablespace TEMPSAPCE1 as a work area to store the intermediate results.
使用空间数据类型，开发人员可以表示使用坐标系统的数据，比如形状、线条或是地图上的点。
The Spatial data type allows developers to represent data that USES a system of coordinates, such as shapes, lines, or points on a map.
现在内核已经使用新系统调用完成更新了，接下来看一下从用户空间应用程序中使用这些系统调用需要执行的操作。
Now that kernel is updated with a few new system calls, let's look at what's necessary to use them from a user-space application.

您可以使用一个（系统可知）布署概要文件,浏览工作空间,或浏览文件系统选择一个概要文件。
You can choose one of the available (system-known) deployed profiles, browse the workspace, or browse the file system to select a profile.
大多数系统甚至允许您在NFS安装的文件系统上使用交换文件，当您没有本地磁盘空间可用时，就可以使用这样的文件系统。
Most systems even let you use swap files on NFS mounted filesystems, which can be used when you have no local disk space available.
这并不意味着系统内核能够肆无忌惮的使用物理内存，系统内核只能使用其管辖的虚拟地址空间所对应的物理内存。
This does not mean the kernel USES that much physical memory, only that it has that portion of address space available to map whatever physical memory it wishes.
持久性预分配如果一个应用程序需要在实际使用磁盘空间之前对它进行分配，大部分文件系统都是通过向未使用的磁盘空间写入0来实现分配。
Persistent preallocation If an application needs to allocate disk space before actually using it, most file systems do so by writing 0s to the not-yet-used disk space.
使用2 - d地图时保持精确度需要理解空间引用系统并合理使用。
Preserving accuracy when using a 2-d map requires understanding spatial reference systems and using them appropriately.
在进程地址空间大于物理内存的系统中，内存泄漏或本机内存过度使用会迫使操作系统提供一些虚拟地址空间。
When running on a system with more process address space than physical memory, a memory leak or excessive use of native memory will force the OS to swap out some of the virtual address space.
例如，一种文件系统可能是以提高速度为目的而优化的，另一种文件系统偏重高效地使用空间，还有一种文件系统偏重于防止数据丢失或损坏。
For example, one file system may be optimized for speed, another for efficient use of space, and yet another for durability against data loss or corruption.
