测试中央管理器机器的失效切换。
中央管理器机器的名称:ha
在这种情况下,LoadLeveler集群中的其他机器将认为中央管理器机器不再运转。
In such cases, the other machines in the LoadLeveler cluster will believe that the central manager machine is no longer operating.
一组客户机机器从属于某个中央管理器机器的形式,称作是LoadLeveler集群,LoadLeveler集群由配置文件来定义。
A group of client machines reporting to a central manager machine is referred to as a LoadLeveler cluster, and a LoadLeveler cluster is defined by a configuration file.
中央管理器机器(centralmanager machine):中央管理器的角色是,基于作业的需求在LoadLeveler集群中找到将要运行那个作业的一台或多台机器。
Central manager machine: the role of the central manager is to find one or more machines in the LoadLeveler cluster, based on the job's requirements, that will run the job.
ha2作为备份的调度机器和中央管理器。
Ha2 ACTS as a backup scheduling machine and central manager.
可以通过在ha4机器上杀死名为 Loadl_negotiator 的中央管理器进程来测试失效切换。
You can test failover by killing the central manager process called Loadl_negotiator on the ha4 machine.
ha1作为主调度机器和中央管理器。
Ha1 ACTS as a primary scheduling machine and the central manager.
当某个备用中央管理器成为中央管理器时,作业不会丢失,但集群中所有的机器向新的中央管理器汇总这些作业可能需要一会儿的时间。
When an alternate becomes the central manager, jobs will not be lost, but it may take a few minutes for all of the machines in the cluster to check in with the new central manager.
在生产环境中,建议将中央管理器和调度后台程序安排在不同的机器上。
In a production environment, I recommend putting the central manager and scheduling daemon on separate machines.
为了防止中央管理器后台进程在同一台机器被重新启动,您应该将RESTARTS_PER_HOUR设置为0。
To prevent the central manager daemon from being restarted on the same node again, you should set the RESTARTS_PER_HOUR keyword to 0.
