At this point, the only usable function in the job manager console is the configuration of the job manager server, mail sessions, security, and troubleshooting functions.
事务管理器能够处理资源管理器的灾难性故障非常重要，这样当一个资源管理器出现故障时，其余的仍能继续照常运行。
It is important that the transaction manager is able to handle catastrophic failures of the resource managers, and as such continue operating if one of the resource managers has a failure.
默认情况下，消息是基于队列管理器可用性实现负载平衡的，而不是基于消息使用方应用程序的可用性。
By default, messages are load balanced based on queue manager availability, but they are not load balanced based on the availability of message consumer applications.
本节向您介绍如何测试部署管理器的高可用性。
This section shows you how to test the high availability of the deployment manager.
其他所有命令：这些命令用于启动和停止队列管理器、启动和停止通道、刷新安全性等。
All other commands: these include commands to start and stop the queue manager, start and stop channels, refresh security, and so on.
开关可以禁用特定安全性检查，或者关闭整个队列管理器的全部安全性。
Switches can disable particular security checks, or turn off all security for the entire queue manager.
事务管理器应该在资源管理器可用时，能够检测到其可用性。
The transaction manager should be able to detect the availability of the resource manager as it becomes available.
有了这个新的可用性选项，多实例队列管理器的信息和数据通过网络文件系统协议(NFS)，比如nfsV4，存储在网络存储设备上。
With this new availability option, the messages and data for a multi-instance queue manager are held on networked storage accessed via a network file system (NFS) protocol, such as NFS V4.
设置新队列管理器的安全性或检查现有队列管理器的配置文件时的出发点应该是考虑哪些访问需要保护。 也就是说，哪些人可以发出哪些命令？
The starting point when setting up security for a new queue manager, or reviewing the profiles for an existing queue manager, should be to consider what needs to be secured.
它验证了随机密码管理器符合陆军的安全性、兼容性和可持续性要求。
It verifies that Random Password Manager has met the Army's requirements for security, compatibility, and sustainability.
此外，应用程序使用事务管理器来确保数据交换的可靠性。
In addition, the application USES a transaction manager to ensure the reliability of data exchange.
使用命令资源安全性确保只有队列管理器的管理员能够修改任何种类的SYSTEM资源，如队列和通道。
Use command resource security to ensure that only the queue manager's administrators can modify SYSTEM resources of any kind, such as queues and channels.
如果已经为一个新队列管理器设置了安全性，最好不要定义任何禁用安全性的开关。
If security is being set up for a new queue manager, then it is probably best not to define any switches that disable security.
您可以使用依赖注入来满足进行企业级开发（例如，数据源或事务管理器）所遇到的许多依赖性。
You can use dependency injection to satisfy the many dependencies you run across when you're doing enterprise development, like data sources or transaction managers.
如果开关禁用某种安全类型，对队列管理器的总体安全性会产生什么影响？
If switches disable some type of security, what effect will that have on the security of the queue manager overall?
这一点有助于确保事务管理器的有效性，并且在一定程度上帮助简化应用程序逻辑。
This helps ensure the availability of the transaction manager and, to some extent, can help simplify application logic.
首先编写一个脚本，遍历一组队列管理器，使用MO72收集队列管理器的安全性设置的细节，并将其与目标基准进行比较。
Starting with a script that iterates through a list of queue managers, I use MO72 to gather details of the security Settings on the queue managers and compare these to a target baseline.
当一个EJB组件想访问数据库、消息队列服务器或者其它一些事务性资源时，它需要到资源管理器的连接(通常是使用JNDI)。
When an EJB component wants to access a database, a message queue server, or some other transactional resource, it acquires a connection to the resource manager (usually by using JNDI).
这个视图提供了关于每个托管系统的相关特征的信息，包括其当前的运行状态，以及与WPAR管理器之间的连接性。
This view provides information about the characteristics of each managed system, including its current operational state and connectivity with the WPAR Manager.
即使启用了安全性，部署管理器仍然使用未经过身份验证的协议向节点代理发送配置更新。
Even when security is enabled, the deployment manager continues to communicate configuration updates to the node agents using an unauthenticated protocol.
从而可以提高事件管理器自身的容错性及其可用性。
You therefore increase event manager's own fault tolerance, and hence, its availability.
