the shared memory segment的意思|示意

All we know is that the database Shared memory ends at 0xfe002000, because starting at that address is a segment for anonymous memory.

我们只知道，数据库共享内存在0xfe002000结束，因为从这个地址开始的是一个用于匿名内存的段。

The segment starting from 0x10000000 to 0x3fffffff is the instance Shared memory, for a total of 0.75gb.

从0x10000000到0x3fffffff的段是实例共享内存，总共是0.75 GB。

Therefore, the largest shared memory segment, in quadrant 3, that DB2 is allowed to allocate is 1GB; and in quadrant 4 is 0.75GB.

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。

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。

The shmmax specifies the maximum size in bytes of a Shared memory segment which can be allocated on the system.

shmmax按字节指定了系统中可以分配的最大共享内存段。

Note: DB2 will take away one segment from the database Shared memory for each of the following configurations, starting from segment b.

注意：对于下面的每种配置，DB 2将从数据库共享内存中拿出一个段，这个段始于段b。
