Only those images that correspond to a consistent snapshot are written to the checkpoint file, and the row shadows allow the currently executing transactions to run unrestricted during checkpointing. 只有那些与一致性快照相符的镜像被写到检查点文件,行影子使当前执行的事务可以在检查点创建期间不受限制地运行。
If the current checkpoint was invalid, the file system need only step back to the last good checkpoint for a valid file system. 如果当前检查点失效,文件系统只需回滚到上一个有效的检查点,重新获得有效的文件系统。
If a crash occurs, the journal can be used as a checkpoint to recover unsaved information and avoid corrupting file system metadata. 一旦系统发生崩溃,日志文件就会起到一个检查点的作用,用于恢复未保存的信息,防止损坏文件系统元数据。
Each successive save creates a new delta checkpoint, enabling you to track the history of the configuration repository changes at the file level. 每次后续的保存都将创建一个新delta检查点,使您能够在文件级别跟踪配置存储库更改的历史。
A checkpoint file is damaged. 检查点文件被损坏。
If a package is configured to use checkpoints, information about package execution is written to a checkpoint file. 如果包配置为使用检查点,则关于包执行的信息会写入检查点文件中。
The lag between the incremental checkpoint target and the log tail is also limited by90% of the smallest online log file size. 增量检查点和日志末尾之间的间隔被最小在线日志文件大小的90%所限制。
This is also mostly likely to happen to a checkpoint file. 检查点文件很可能也出现这种情况。
The checkpoint file tracks the transaction log entries that have been committed to the database. 检查点文件会跟踪已提交给数据库的事务日志条目。
To successfully restart a package, the package identifier in the checkpoint file and the package must match; otherwise the restart fails. 若要成功重新启动包,检查点文件中的包标识符和包必须匹配,否则重新启动将失败。
A checkpoint file either could not be found or is damaged. 检查点文件可能找不到或被损坏。
This error indicates that a corrupt checkpoint file has been deleted. 此错误指示损坏的检查点文件已删除。
If the checkpoint file exists, the package restarts from the point of the previous execution failure; otherwise, it runs from the start of the package workflow. 如果检查点文件存在,则包从上一次执行失败的点重新启动;如果检查点文件不存在,则包从包工作流的起点开始运行。
Database files have a similar header, and so does the checkpoint file. 数据库文件和检查点文件具有类似的头信息。
If the checkpoint file is not found, the package fails. 如果找不到检查点文件,则包失败。
The transaction log file path and checkpoint file path are specified on the storage group property page and are depended upon by all databases in that storage group. 事务日志文件路径和检查点文件路径在存储组属性页上指定,该存储组中的所有数据库都依赖于这些路径。
You can, however, view the checkpoint file header while databases are mounted. 不过,在装入数据库时您可以查看检查点文件头。
This error indicates that the checkpoint file does not match the transaction log files. 此错误指示检查点文件与事务日志文件不匹配。
This prevents a package from using a checkpoint file written by a different package version. 这样可以防止包使用其他包版本所写的检查点文件。
Removing the checkpoint file will correct this error. 删除检查点文件将更正此错误。
Specifies the name of the checkpoint file. 指定检查点文件的名称。
When the failed package is rerun, the run-time engine uses the checkpoint file to restart the package from the point of failure. 重新运行失败的包时,运行时引擎将使用检查点文件,以便从失败点重新启动包。
In the process of checkpoint, WAL ( Write-Ahead Logging) rule does not permit updating the database before the corresponding log records having been written into the log file. WAL(WriteAheadLogging)是指当执行检查点时,相应的日志记录刷新到稳定存储器前,不允许对数据库做实际的更新。
Novel checkpoint fault-tolerance scheme of metadata in file system 一种新的文件系统元数据的检查点容错策略
This paper describes the implementation and improvement of the service group-based multi-process checkpoint, and adopts a dynamic checkpoint time interval adjustment mechanism. Thus the impact of the checkpoint file on the application process is reduced. 本文提出了基于服务组的多进程检查点的实现方案,采用了一种动态的检查点时间间隔调整机制,从而减小了检查点文件对应用进程的影响。
Supporting Checkpoint Inside the Linux Kernel& Design of CKPT File System Linux中检查点(Checkpoint)的核心支持&ckpt文件系统的设计
Secondly, this thesis introduces the key technology of checkpoint system, such as injecting DLL, intercepting and wrapping API, checkpointing and resuming the state of the opened file etc. 接着介绍了实现检查点系统的关键技术及其原理:DLL的注入,API函数的截获,活动文件的保存和恢复等。
The authors use the checkpoint mechanism of the Linux operating system to interrupt the running process of the Apache server and create Core file which can save the context of the interrupted process of the Apache server. 利用Linux操作系统检查点机制,中断正在运行的Apache服务器进程,进行核心转储产生了Core文件,在这个Core文件中保存被中断进程的上下文。
Additionally, several secondary functions are integrated, including visual analysis, performance prediction, checkpoint setting, job migration, job security. The job definition can be reused, and the file operations are automatic and flexible. 另外还集成了应用程序可视化分析、任务性能预测、检查点设置、任务迁移和任务安全等辅助功能,能够实现任务定义重用和自动灵活的文件操作。
