橙色的那部分(堆),即从0x023f 8000到0x10000000,被用于代理私有内存(~ 220MB)。
We have mentioned that private memory is allocated to a DB2 agent when the agent is "assigned" to perform work.

Within this segment, the db2sysc executables take only a small fraction, the rest is used for agent private memory (200mb +).
在这个段内,db2sysc可执行程序只占用很小的一片内存,剩下的用于代理私有内存(200 MB +)。
It will also allocate a private memory area called PGA, where it stores what is private to the process and to the session.
数据库也会为服务器进程分配私有的内存空间,这块空间叫做PGA(程序全局区),那里存放着私有的进程和会话信息。
The typical consumer of agent private memory is the sort heap memory that is used by the agent to sort rows during query execution.
代理私有内存的常见消费者是排序堆内存,代理在查询执行期间使用这部分内存来对记录行进行排序。
The data/heap region contains dynamically allocated memory and some globally accessible program data (for example, DB2 agent private memory).
data/heap区域包含动态分配的内存和可全局访问的程序数据(例如DB2代理私有内存)。
If you create a joinable thread but forget to join it, its resources or private memory are always kept in the process space and never reclaimed.
如果您创建一个可接合的线程,但是忘记联接它,其资源或私有内存一直保存在进程空间中,从未进行回收再利用。
You can now configure a private memory cache for every CPUVP to decrease the time of server memory allocation on large multiprocessor computers.
现在可以为每个CPUVP配置一个私有内存缓存,以减少大型多处理器计算机上的服务器内存分配时间。
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。
Even though the data segment maps a file, it is a private memory mapping, which means that updates to memory are not reflected in the underlying file.
尽管数据段映射了文件,但这种内存映射是私有的,也就是说,数据段的内存更新不会在其映射的文件中生效。
To understand the difference between Shared and private memory, let's first learn about the DB2 agent processes by quickly reviewing the DB2 process model.
为了理解共享内存与私有内存之间的不同之处,首先让我们通过快速阅读DB 2进程model来了解一下DB 2代理进程。
Even though the data segment maps a file, it is a private memory mapping, which means that updates to memory are not reflected in the underlying file.
尽管数据段映射了一个文件,它是一个私有内存映射,这意味着更新到内存中不反映在底层的文件。
The agent private memory set consist of the following memory pools. Their sizes are specified in the database configuration parameters enclosed in parenthesis.

The application heap size parameter defines the number of private memory pages available to be used by the database manager on behalf of a specific agent or subagent.
应用程序堆大小参数定义了数据库管理器的一个特定代理或子代理所能使用的私有内存页数。
Because each application that attaches to a database requires some private memory to be allocated, allowing a larger number of concurrent applications will use more memory.
