它具有一个集成的内存管理单元，通常使用与PPE类似的页表查询机制来提供对某个进程地址空间的访问。
It has an integrated memory management unit that is normally used to provide access to the address space of one process by using the same page table lookup as the PPE.
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.
如果您有足够的物理内存和地址空间，您可以允许泄漏继续，但必须在进程地址空间耗尽之前重新启动应用程序。
If you have enough physical memory and address space, you can allow the leak to continue on the basis that you will restart your application before the process address space is exhausted.
有时候，如果一个过程或函数不稳定或者在测试中，那么应该将其定义为FENCED，这样就可以在自己的进程地址空间中运行。
Sometimes, if a procedure or function is unstable or is being tested, it will be defined as FENCED so that it can be run in its own process address space.
注意，每个进程可能在其各自的地址空间中映射共享内存区域到不同地址。
Note that each process can map the Shared memory region to different addresses in their respective address Spaces.
这样，每个进程都获得了自己可以使用的地址空间，可以访问比您物理上安装的内存更多的内存。
This way, each process gets its own address space to play in and can access more memory than you have physically installed.
因为中间件实例是不同的，所以每个租户有自己的操作系统进程(地址空间)。
Since the middleware instance is different, each tenant is allocated its own set of operating system processes (i.e. address space).
在用户空间，注意，由于用户进程出现在单独的地址空间，在它们之间移动数据必须经过某种进程间通信机制。
In user space, note that because user processes appear in separate address Spaces, moving data between them must occur through some form of inter-process communication mechanism.
FENCED或NOT FENCED：这个子句指定例程是否被认为可以在数据库管理器操作环境的进程或地址空间中“安全地”运行。
FENCED or NOT FENCED: This clause specifies whether the routine is considered "safe" to run in the database manager operating environment's process or address space.
某些范围的地址空间是专用于特定的进程的，例如内核。
Certain areas of the address space are limited to specific processes, such as the kernel.
进程地址仍限于32位，以便在不同的内存范围中为各个进程产生地址空间。
The process addresses are still limited to 32 bits, yielding address Spaces for individual processes in differing areas of memory.
每个DB 2代理进程都有其自己的内存地址空间。
进程的虚拟地址空间中的区域可被映射到物理内存、文件或任何其他可寻址存储。
Regions in a process's virtual address space can be mapped to physical memory, to a file, or to any other addressable storage.
如果进程保留内存而没有提交，那么该值就与总地址空间的大小有很大的差别。
This can be quite different from the size of the total address space if the process reserves memory but doesn't commit it.
图6展示了用于一个DB 2代理进程的32位内存地址空间。
Figure 6 shows the 32-bit memory address space for a DB2 agent process.
地址空间并不完全用于单个的进程。
The address space is not entirely devoted to a single process.
在这种体系结构中，对于所有平台，每个进程的地址空间都是2的64次方，或者18,446,744,073GB。
With this architecture, the address space of each process is 2 to the power of 64, or 18,446,744,073 GB, on all platforms.
自由：还没有进程使用这部分地址空间。
Free: the process is not yet using that area of the address space.
使用共享内存对象的进程必须在自己的地址空间中映射对象。
For a process to use a Shared memory object, the process has to map the object in its address space.
这允许进程仅为随时需要的网页指定大的地址空间。
This permits a process to have a massive address space that is defined only for the pages that are needed at any given time.
程序的文本和数据段现在需要写入到mem文件中，这可以使用write系统调用，或者通过将该文件映射到该进程的地址空间中实现。
The program text and data segments now need to get written into the mem file, either using the write system call, or by mapping the file into the process address space.
与此相反，只要用户进程状态发生变化，其映射的地址空间也随即改变。
By contrast, the mapping for the user-mode portion of the address space changes whenever a process switch happens.
与此相反，只要用户进程状态发生变化，其映射的地址空间也随即改变。
By contrast, the mapping for the user-mode portion of the address space changes whenever a process switch happens.
