用特殊的系统调用(即对UNIX内核的请求)分配和释放内存并设置权限；通过一般的读写操作读写内存段中的数据。
Special system calls, or requests to the UNIX kernel, allocate and free the memory and set permissions; common read and write operations put and get data from the region.
您可能会忘了跟踪所有指针（指向这些内存位置），并且某些内存段没有释放，还保持分配给该程序。
You might forget to keep track of all the pointers (pointing to these memory locations), and some of the memory segments are not freed and stay allocated to the program.
具体地址分配的过程也会按照层次化的方式划分，每台主要的电气设备会向其控制器请求一个地址段。
The allocation process is again done in a hierarchical zoned way, with each major application requesting a block of addresses from its controller.
现在，属性术语已经对其段表定义了一个资产分配。
Now, the attribute terms already define an asset assignment to their segment table.
由于shmseg内核参数被设得太低，有些共享内存段不能适当地分配。
Because SHMSEG kernel parameter is set too low, some Shared memory segments could not be allocated properly.
段2预留给堆栈和动态内存分配。
该参数按字节指定系统中可以分配的共享内存段的最大大小。
This parameter specifies the maximum size in bytes of a Shared memory segment which can be allocated on the system.
动态段分配让用户堆或共享内存可以使用额外的段。
Dynamic segment allocation allows the additional segments to be used by user heap or Shared memory.
根据进程的不同，DB 2分配各种不同的段。
There are various segments allocated by DB2 depending on the process.
因此，DB2允许分配的最大共享内存段在象限3 中的大小为1GB，在象限4 中的大小为 0.75GB。
Therefore, the largest shared memory segment, in quadrant 3, that DB2 is allowed to allocate is 1GB; and in quadrant 4 is 0.75GB.
SHMMAX 按字节指定系统上可以分配的最大共享内存段。
The SHMMAX specifies the maximum size in bytes of a shared memory segment which can be allocated on the system.
您无法提前知道所分配的一段区域是怎么对齐的，因此最好的方法就是多分配一点存储空间，并获取其中的一个对齐区域。
You can't tell in advance what alignment an allocated region will have, so your best bet is to allocate a bit of extra storage and get an aligned region within it. Here's one way to do that
段3 （蓝色）被分配给实例共享内存。
例如，模块3使用malloc所分配的一段内存空间可以由模块2释放，因为对malloc和free的调用都是由同一个CRT对象实现的。
For example, a memory chunk allocated with malloc in Module 3 can be freed in Module 2 with free. It is because both malloc and free calls will end up in the same instance of CRT.
如果大型对象均被存于heap的特定段内，那么它们可更容易地被分配；并且，较小的对象无需与它们争夺heap使用。
If the large objects are kept within a certain segment of the heap, they can be more easily allocated; moreover, smaller objects do not need to compete with them to gain heap usage.
shmmax按字节指定了系统中可以分配的最大共享内存段。
The shmmax specifies the maximum size in bytes of a Shared memory segment which can be allocated on the system.
这个连接过程称为映射，它给共享内存段分配每个进程的地址空间中的本地地址。
Annexation is called mapping, where the Shared segment of memory is assigned local addresses in each process 'own address space. Figure 1, Figure 2, Figure 3, and Figure 4 depict the process.
Esid列显示已经分配的内存段
The Esid column displays the memory segments that have been allocated
如果动态段分配调用shmat或mmap，那么其余的段(0x3到0xf)供用户进程使用。
The rest of the segments (0x3 to 0xf) are available for the user process is shmat or mmap is called by dynamic segment allocation.
使用一个称为分页空间预分配的过程，通过将段划分为页面，可以完成这项任务。
It does this by using a process called early allocation of paging space, by partitioning segments into pages.
通过时间段划分和时间的平衡分配，你将会需要一些时间来休息。
By setting boundaries and striking a balance you'll be able to take some much needed time off.
休息后，对这组成员进行另外三个星期的第二阶段的实验，分配给青少年摄入量的钙。
After a break, the groups resumed the experiment for another three weeks, with teens assigned to a different calcium intake level for the second stage.
早期，大型机的管理员，要做这样一些工作- - - - -接收程序执行的请求，给程序分配相应的优先级，然后，分给程序一个运行的时间段。
Early main-frame system administrators had the job of taking program execution requests, assigning them a priority, and giving them a time frame to run.
这样，由于调用者被转入休眠状态，可能需要一段比较长的时间才能完成分配，调用者的需求才能得到满足。
This might take a longer time to complete since the caller is put to sleep in order to satisfy requirements.
对于新手来，简单地说，时间盒就是把时间段分配到一个或一组任务。
For those new to it, time boxing is simply fixing a time period to work on a task or group of tasks.
在其分配的时间段中，它的作用是在时间用完之前跟踪根对象及其引用的对象，并且需要将JV m调回ii段。
In its allotted time period, it manages to trace through the root object as well as the object that it references, before running out of time and needing to schedule the JVM back in section II.
Solaris中另一个与分配数据库共享内存有关的常见问题是由于这样的一个事实导致的，即共享内存段的所有页都是固定在物理ram中的。
Another common problem with allocating database Shared memory on Solaris is due to the fact that all pages of a Shared memory segment are pinned in physical RAM.
