shared memory segment的意思|示意

Communications segment: the Shared memory communications portion, also known as the message portion, is used as a communication mechanism by the client and server processes.

通信段：共享内存通信区，也被称为消息区，被作为客户机和服务器进程的一种通信机制。

This is well under the 1.75gb Shared memory limit, and each database Shared memory segment can safely map contiguously to a quadrant.

这低于1.75 GB的共享内存限制，并且每个数据库共享内存段可以安全地连续映射到一个象限。

Therefore, if you enable ESTORE, make sure it is at least 256mb or else it would not make sense, because a segment of 256mb from the database Shared memory is taken for just managing the ESTORE.

因此，如果启用ESTORE，则应确保它至少是256 MB，否则就不起作用，因为要从数据库共享内存中拿出一个256 MB的段来仅用于管理这个ESTORE。

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.

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。

This program also allows you to display the subsystem Shared memory segment for debugging purposes.

这个程序还允许您为调试目的显示子系统共享内存段。

Finally, in Figure 4, processes a and B can read and write from the Shared memory segment freely.

最后，在图4中，进程a和B可以随意读写共享内存段。
