进程检查点机制是在进程正常运行的适当时刻设置检查点，将进程状态保存到稳定存储器中。
Checkpoint facility enables the intermediate state of a running process to be saved to stable storage.
在这种应用中，可以以特定的间隔(检查点)冻结一组相关的进程，然后解冻特定的时间点以回到某个已知状态。
In this application, you could freeze a collection of related processes at specific intervals (checkpoints), then thaw a particular epoch as a way to roll back to a known good state.
在使用WPAR管理器重新部署WPAR时，将为所有的进程设置检查点，然后在目标系统中重新启动，从而对应用程序或者WPAR用户产生最小的影响。
When a WPAR is relocated using WPAR Manager, all processes are checkpointed and then restarted on the target system, with minimal impact on the application or WPAR user.
还有一个secondarynamenode，它不是 namenode的冗余守护进程，而是提供周期检查点和清理任务。
There's also a secondary namenode, which isn't a redundant daemon for the namenode but instead provides period checkpointing and housekeeping tasks.
许多文献已指出检查点开销主要是来自于对进程状态的保存。
Some papers had mentioned that the overhead of checkpoint mainly dues to save the process's state into stable storage.
后台检查点进程已挂起，直到有可用的锁。
Background checkpoint process suspended until locks are available.
通过在广播确认消息中捎带哪些进程产生了新的检查点的信息，使每个进程的检查点序号在所有进程中是一致的。
Through piggybacking the information about which processes have taken new checkpoint in the broadcast message, the checkpoint sequence number of each process is consistent in all processes.
监测代理利用检查点和进程迁移技术来实现对进程的状态监测和故障恢复。
Detection agents make use of checkpoint technology and process migration technology to detect the process state, recovery the process from the fault state.
该策略不会产生多米诺效应且不需要记录任何进程间消息，缩短了进程阻塞消息发送时间，且检查点生成过程中使进程得以同步，因此算法具有较好性能。
The strategy can avoid domino effect and log message between processes, which makes the blocking message-sending time shorter, and synchronizes processes in the process of checkpointing.
着重讨论了检查点和进程迁移两大高可用技术。
We emphasize on the HA technique of Checkpoint and Process Migration.
通过在广播确认消息中捎带哪些进程产生了新的检查点的信息，使每个进程的检查点序号在所有进程中是一致的。
Through piggybacking the information about which processes have taken new checkpoint in the broadcast message, the checkpoint sequence number of each pro...
检查点机制的状态检查操作就是将进程在该运行时刻的用户级寄存器上下文和用户数据段保存到检查点文件中。
Statecheck operation of checkpoint preserves the user register context and user data segment of process checkpointed at this time to checkpoint file.
检查点机制的状态检查操作就是将进程在该运行时刻的用户级寄存器上下文和用户数据段保存到检查点文件中。
Statecheck operation of checkpoint preserves the user register context and user data segment of process checkpointed at this time to checkpoint file.
