Operating system error 32(failed to retrieve text for this error. Reason: 15105)

一台数据库服务器的作业日志备份作业偶尔会冒出几遍备份战败的动静,具体的错误新闻为:

 

 

DATE/TIME:    2018/7/30
12:10:52

 

DESCRIPTION:
BackupDiskFile::CreateMedia: Backup device
‘M:\DB_BACKUP\LOG_BACKUP\xxxx_[2018-07-30_06h03m10_Mon]_logs.TRN’
failed to create. Operating system error 32(failed to retrieve text for
this error. Reason: 15105).

      关于Operating
system error 32,这么些错误代码对应的错误新闻为:

 

     The
process cannot access the file because it is being used by another
process.

 

 

   其实在此之前刚好遭逢过那样的案例,使用AplexSQL
Log去分析事情日志的备份文件,YourSQLDba的事体日志备份的时候,就会赶上上边错误(YourSQLDba_LogBackups事务日志备份会追加到同一个备份文件),不过这么些怎么固定那么些错误呢?其实出现那一个荒唐,一定有连带进程在造访工作日志备份文件,那么只要排查那一个应用或程序即可。刚好近年来布置了AWS的DMS的(DMS简单介绍如下,具体参考官方文档https://docs.aws.amazon.com/zh\_cn/dms/latest/userguide/Welcome.html)

 

 

在最基本级别上,AWS DMS 是 AWS
云中运作复制软件的服务器。您创设源和对象连接以告知 AWS DMS
要开展领取和加载的职分。然后,布置在此服务器上运行以动迁数据的任务。AWS DMS
会成立表和关系的主键 (要是它们在目的上不存在)。倘诺你愿意,则可以优先手动创造目标表。或者,也可以使用 AWS SCT
创设部分或任何目的表、索引、视图、触发器等。

因为DMS有时候会读取事务日志备份文件中的内容,通过DPA监控,刚好找的了那么些DMS的账号,在作业日志备份的光阴点在履行上面SQL语句(如下所示)。那么就是因为那一个进度在读取事务日志备份中内容(跟一般的Replication有点不一致),导致事情日志备份出现Operating
system error 32张冠李戴(The
process cannot access the file because it is being used by another
process)
