这样便迫使DB2将段E用于本地连接，从而为数据库共享内存空出一个段。
This forces DB2 to use segment E for local connections, thus freeing one segment for database shared memory.
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.
如果有用户或应用程序以绑定模式连接(使用共享内存)，操作系统将使用ID和密码对其进行身份验证。
If there are users or applications connecting in bindings mode (using Shared memory), the operating system will authenticate them using an ID and a password.
如果您至少将一个连接配置为IPC共享内存连接，那么在初始化ids时将分配处理器间的通信或消息区。
Inter processor communications or messages portion is allocated during IDS initialization if you configure at least one of your connections as an IPC shared-memory connection.
某个客户机连接到服务器所创建的共享内存区域。
A client can attach the Shared memory region created by the server.
该区的尺寸相当小，可用12kb乘以共享内存通信(NETTYPEipcshm)所需的预期连接数目来计算该尺寸。
The size of this portion is pretty small and can be calculated using 12 kilobytes multiplied by the expected number of connections needed for shared-memory communications (NETTYPE ipcshm).
这个连接过程称为映射，它给共享内存段分配每个进程的地址空间中的本地地址。
Annexation is called mapping, where the Shared segment of memory is assigned local addresses in each process 'own address space. Figure 1, Figure 2, Figure 3, and Figure 4 depict the process.
换句话说，不能激活数据库或连接到数据库，因为没有足够的共享内存来满足请求。
In other words, the database failed to activate or connect because there was not enough Shared memory to meet the request.
数据库共享内存是在数据库被激活或者第一次被连接上的时候分配的。
Database Shared memory is allocated when a database is activated or connected to for the first time.
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.
因为绑定模式连接使用共享内存，所以不存在与网络连接上的传输关联的开销。
Because the bindings mode connection USES Shared memory, there is no overhead associated with transport over a network connection.
数据库共享内存：这是数据库全局内存，是在激活数据库或者第一次连接到数据库时分配的。
Database Shared memory: This refers to the database global memory, which is allocated when the database is activated or connected to for the first time.
每个连接到数据库的应用程序都会被分配内存；因此，正确地配置会影响应用程序共享内存的参数非常重要。
Each application connected to the database has memory allocated to it; therefore accurate configuration of the parameters affecting the application Shared memory becomes crucial.
共享内存是从系统的空闲内存池中分配的，希望访问它的每个进程连接它。
Instead, Shared memory is allocated from the system's free memory pool and is annexed by each process that wants access.
如果数据库是分区的，或者启用了intra - parallel或连接集中器，那么数据库共享内存中有一个段被预留给应用程序组共享内存。
If the database is partitioned, or intra-parallel enabled, or connection concentrator enabled, then one segment is used for Application Group Shared Memory.
shm_open：创建共享内存段或连接到现有的已命名内存段。
Shm_open : Creates a Shared memory region or attaches to an existing, named region.
共享资源包括内存中的数据比如实例或类变量和外部对象比如文件、数据库连接以及网络连接。
Shared resources include in-memory data such as instance or class variables and external objects such as files, database connections, and network connections.
共享资源包括内存中的数据比如实例或类变量和外部对象比如文件、数据库连接以及网络连接。
