instance_memory参数只是设置了实例共享内存的限制。
By default, the starting address of the instance Shared memory is fixed at 0x10000000.
在默认情况下，实例共享内存的起始地址固定于0x10000000。
Same logic applies to the instance Shared memory and the application group Shared memory.
这样的逻辑同样适用于实例共享内存和应用程序组共享内存。
Note that the instance shared memory now starts at 0x12000000 instead of the default address 0x10000000.
注意，实例共享内存现在从0x12000000 开始，而不是从默认地址 0x10000000 开始。

所有3个绿色的段被用于共享内存，包括实例共享内存和数据库共享内存。
If the DB2DBMSADDR register variable is set, then the instance Shared memory will start at the address specified by this variable.
如果设置了DB2DBMSADDR注册表变量，那么实例共享内存将从该变量指定的地址开始。
The following output indicates 42 MB of memory is reserved for the instance shared memory set (10313 pages * 4096 bytes per page)
下面的输出表明有 42MB 的内存被预留给实例共享内存集（10313页 * 4096字节/页）
Note this amount includes both the instance Shared memory and database Shared memory, and their memory segments must be contiguous.
注意这个数量同时还包括实例共享内存和数据库共享内存，并且它们的内存段必须是邻接的。
Since the end address of the instance Shared memory is not fixed, the starting address for the database Shared memory is not fixed either.
因为实例共享内存的结束地址不固定，所以数据库共享内存的起始地址也是不固定的。
Instance Shared memory is allocated when the database manager is started (db2start), and freed when the database manager is stopped (db2stop).
实例共享内存是在数据库管理器启动(db2start)时分配的，并随着数据库管理器的停止(db2stop)而释放。
So far we have discussed the instance Shared memory, the database Shared memory, the application group Shared memory and the agent private memory.
至此，我们已经讨论了实例共享内存、数据库共享内存和应用程序组共享内存以及代理私有内存。
The agent private memory can be increased by moving the instance Shared memory to a higher address by setting the DB2DBMSADDR DB2 registry variable.
我们可以通过设置DB2DBMSADDRDB 2注册表变量，将实例共享内存移到更高的地址，从而增加代理私有内存。
The overflow buffer is used to satisfy peak memory requirements for any heap in the instance Shared memory region whenever a heap exceeds its configured size.
每当某个堆超出了其配置的大小时，便可以使用溢出缓冲区来满足实例共享内存区内任何堆的峰值需求。
The above example showed that although 42 MB is memory is reserved for the instance Shared memory set, only about 21 MB is being used at the time db2mtrk is run.
上面的例子表明，虽然预留给实例共享内存集的内存有42MB，但在db2mtrk运行时只用到了大约21 MB。
Instance Instance Processes and Shared memory; in DB2, it also includes a permanent directory structure.
实例实例进程和共享内存；在DB 2中，它还包含一个永久目录结构。
The Shared memory available per instance, then becomes, 1gb plus whatever space is still available in quadrant 4.
于是，每个实例的可用共享内存就变为1gb加上象限4中仍然可用的空间。
