The slot manager runs as a daemon to control the number of token slots provided to applications, and it interacts with applications using a Shared memory region.
应用程序共享内存：这是在应用程序连接到数据库时分配的内存，由处理连接到数据库的客户机所请求的工作的代理使用。
Application Shared memory: This refers to the memory allocated when an application connects to a database and is used by agents that do the work requested by the connected clients.
SHMVP：当应用程序正在使用通信的共享内存方法时，该类将为新连接处理轮询任务。
SHM VP: Handles the task of polling for new connections when the application is using the shared memory method of communication.
真实的应用程序会使用信号量或其他技术控制对共享内存段的读写。
A real application would use semaphores or other techniques to control reading and writing to the Shared segment.
通信区包含本地客户机应用程序的消息缓冲区，这些应用程序使用共享内存与数据库服务器进行通信。
The communications portion contains the message buffers for local client applications that use shared memory to communicate with the database server.
属于相同应用程序组的所有DB 2代理都使用应用程序组共享内存进行通信。
All the DB2 agents belonging to the same application group communicate using the application group Shared memory.
任何其它试图使用子系统的应用程序必须首先附加到共享内存区域并作为API初始化进程的一部分注册，所以pkcsslotd知道应用程序。
Any other applications attempting to use the subsystem must first attach to the Shared memory region and register as part of the API initialization process, so pkcsslotd is aware of the application.
在其他平台上，使用ConstrainedSHMSizeMB减少共享内存，就会自动地增加应用程序的私有空间。
On other platforms, using ConstrainedSHMSizeMB to reduce the Shared memory automatically increases the amount of private data space for the application.
下面，我们将探索这种Linux内存共享方法，以及如何使用该方法提高服务器的内存密度，从而增加其托管其他应用程序或VMs的能力。
Now, let's explore the Linux approach to memory sharing and how you can use it to increase the memory density of a server and therefore increase its ability to host additional applications or VMs.
在当前使用的AIX大内存模型中，ConstrainedSHMSizeMB应该只用来支持需要共享内存的第三方应用程序。
In the currently used AIX large memory model, ConstrainedSHMSizeMB should be used only to support third-party applications that require Shared memory.
随着 HP-UX 10.20内核的更改，可以通过编译应用程序使之使用 SHMEM_MAGIC 内核可执行程序，可以将全局共享内存的限制从 1.75G增加到 2.75GB。
Under HP-UX 10.20 kernel changes, it is possible to increase the global shared memory limit from 1.75G to 2.75GB, by compiling the application to use the SHMEM_MAGIC kernel executable.
如果希望与 HPC和数据库应用程序中常用的共享内存结合使用大页面，还需要设置 v_pnshm值：#vmo-p-o v_pinshm=1。
If you want to use large pages in combination with shared memory, which is often used in HPC and database applications, you will also need to set the v_pnshm value: # vmo -p -o v_pinshm=1.
