扩展DB 2服务器涉及将一个或多个成员添加到现有数据共享组中。
Scaling DB2 servers involves just adding one or more members to existing data sharing group.
Sysplex查询并行(一个DB 2数据共享组中的多用户和多任务)是在DB 2UDBv5中引入的。
CP parallelism (multiple tasks on multiple CPs) was implemented in DB2 V4. Sysplex query parallelism (multiple tasks on multiple members of a DB2 data sharing group) was introduced in DB2 UDB V5.
如果某一个db2子系统停机，或者出于维护的目的暂时离线，那么数据共享组中的其他DB 2子系统就会接管目前离线的数据共享成员的工作负载。
If one DB2 subsystem goes down, or brought off-line for maintenance, other DB2 subsystems in the data sharing group take on the workload of the data sharing member that is now offline.
CP并行可以在db2子系统中为一条查询使用多个任务，而sysplex查询并行这种方法使一个DB 2数据共享组中的所有成员可以一起处理一个查询。
While query CP parallelism used multi-tasking for a query within a DB2 subsystem, this method enables all the members of a DB2 data-sharing group to process a single query.
应用程序组内存集是从数据库共享内存集中分配的。
The application group memory set is allocated from the database Shared memory set.
由于许多原因，用户可能有意选择把产品安装在不同的包组中，即使这些产品有能力共享资源。

其他团队成员可以访问共享文件夹，把服务器概要文件或部署组导入到自己的工作空间中。
Other team members can then go to the Shared folder and import the same Server Profiles or Deployment Groups into their own workspaces.
在备用节点上，可以访问共享的增强型并发卷组，但是只能采用被动只读模式。

一个可用系统是由一组系统级共享资源组成的系统，共同合作提供重要服务。
An available system is one that comprises a set of system-wide, Shared resources that cooperate to provide essential services.
还有使用ACE 实现IPC的其他方法，比如共享内存或UNIX 风格的套接字寻址（ACE_LSOCK*组中的类）。
There are several other ways of initiating IPC using ACE, like shared memory or UNIX-style socket addressing (the ACE_LSOCK* group of classes), which this article does not address.
在这种模式下，多个Power ha节点都可以访问共享卷组，这会加快发生节点故障时的故障转移(磁盘接管)。
In this mode, the Shared volume groups are accessible by multiple PowerHA nodes, which results in faster failover (disk takeover) in the event of a node failure.
KeepandShare- - - Keep and Share是一组文件共享系统。
Keep and Share - Keep and Share is a group file sharing system.
应用程序组共享内存集是： 40000页 *4K/页 = 160MB
The application group shared memory set is: 40000 pages * 4K per page = 160 MB
应用程序组共享内存集没有列出，因为它是从数据库共享内存集中分配的。
Application group Shared memory set is not listed because it is allocated from the database Shared memory set.
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。
So far we have discussed the instance Shared memory, the database Shared memory, the application group Shared memory and the agent private 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。
Same logic applies to the instance Shared memory and the application group Shared memory.
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.
要增强ACL的可管理能力，必须对实体进行分组，然后为这些组提供对不同共享资源的访问权限。
To make ACL storage manageable, entities are grouped, and these groups are then provided permissions on different Shared resources.
它在进行快速数据共享和驱动由数十个数据库24x 7组成的复杂层级时很方便。
It comes in handy for quick data sharing as well as to power complex hierarchies of dozens of databases 24x7.
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.
但他也注意到，之前的网络技术在当时同样也引起了类似的担忧，例如新闻组，web技术和文件共享，这些每一个受带来了网络流量的大幅增加。
But he notes that similar worries arose with previous Internet technologies, such as newsgroups, the web and file-sharing, all of which involved big increases in the amount of network traffic.
在实现时可以对某一服务(或接口方法)进行角色(不同权限组)级的安全设置，从而保证数据共享时数据的安全性。
Some safety setting depended on different roles can be done to some kind of service (or interface method) to ensure the security when the data are Shared.
之所以需要组是为了让属于同一组的用户能够共享资源。
Groups exist mostly so that resources can be Shared between users belonging to the same group.
之所以需要组是为了让属于同一组的用户能够共享资源。
