ORA-00377: Frequent backups of file string causing write operation to stall

文档解释

ORA-00377: Frequent backups of file string causing write operation to stall

Cause: Backups are occurring too frequently on this file. Each time a new backup is started for a file, any writes which have been previously issued (but not completed) have to be re-issued. If hot backups are started very, very frequently, it is possible that some writes will be re-issued repeatedly and never complete.

Action: Increase the interval between begin hot-backup commands for this file.

ORA-00377，也被称为文件IO写操作超时，是一个基于UNIX系统的通用错误，表明一个或者多个文件写操作试图写入服务器，但是因为某些原因(如磁盘空间不足)超出了操作的超时时间。

官方解释

ORA-00377: “file write operation timed out”失败，表明一个文件操作正在被进行，但是超时。

常见案例

ORA-00377通常出现在做文件系统备份时，导致写操作无法完成。这可能是因为在开始写操作之前，磁盘空间由于将该文件复制到其他目录而耗尽。

正常处理方法及步骤

1. 首先检查硬盘空间是否已经耗尽，如果是，需要删除不必要的文件来释放空间；

2. 接下来，应该检查文件备份的频率是否过高，如果是，应该减少文件备份的频率；

3. 最后，检查服务器上安装的系统和软件是否是最新的，如果不是，应该尽快升级到最新版本。
