AWS DMS构建表列表失败

Question

我试图从SQL服务器到Aurora-mysql完全加载，但任务失败了一些错误。我想知道为什么AWS在这方面的描述如此便宜。

  [TASK_MANAGER ]I: Execute Request Task 'LEDGD7DCQS4IBQSXXQF66YPLIU' running full load only with flags fresh start with cdcPosition null and stop_at null (replicationtask.c:702)
    [TASK_MANAGER ]I: Task 'LEDGD7DCQS4IBQSXXQF66YPLIU' running full load only in fresh start mode (replicationtask.c:1239)
    [TASK_MANAGER ]I: Task Id: bdef8ae7-25e8-432c-bf33-06f6fc86e673 (replicationtask.c:3008)
    [TASK_MANAGER ]I: Creating threads for all components (replicationtask.c:1869)
    [TASK_MANAGER ]E: Build tables list failed [1020486] (replicationtask.c:1993)
    [TASK_MANAGER ]E: Task 'LEDGD7DCQS4IBQSXXQF66YPLIU' failed [1020486] (replicationtask.c:3038)
    [TASK_MANAGER ]W: Task 'LEDGD7DCQS4IBQSXXQF66YPLIU' encountered a fatal error (repository.c:4704)
    [TASK_MANAGER ]I: Task Management thread terminated abnormally (replicationtask.c:3645)

为什么“构建表列表失败”我需要检查什么...查看文档，但没有。

Answer 1

'恢复'代替'重启'为我做了工作。

Answer 2

也许尝试将SOURCE_UNLOAD的默认日志记录设置为更精细的级别。这两个都低于默认级别。

LOGGER_SEVERITY_DEBUG - 将调试消息，信息性消息，警告和错误消息写入日志。

LOGGER_SEVERITY_DETAILED_DEBUG - 所有信息都写入日志。

您需要使用CLI创建任务并为此引用自定义任务设置文件。

对于在DMS EndPoint上配置的用户，您可能需要额外的GRANT。

 GRANT SELECT ON FN_DBLOG TO dmstest;
 GRANT VIEW SERVER STATE TO dmstest;
 use msdb;
 GRANT EXECUTE ON MSDB.DBO.SP_STOP_JOB TO dmstest;
 GRANT EXECUTE ON MSDB.DBO.SP_START_JOB TO dmstest;
 GRANT SELECT ON MSDB.DBO.BACKUPSET TO dmstest;
 GRANT SELECT ON MSDB.DBO.BACKUPMEDIAFAMILY TO dmstest;
 GRANT SELECT ON MSDB.DBO.BACKUPFILE TO dmstest;
