ORA-01114: IO error writing block to file string (block # string)

文档解释

ORA-01114: IO error writing block to file string (block # string)

Cause: The device on which the file resides is probably offline. If the file is a temporary file, then it is also possible that the device has run out of space. This could happen because disk space of temporary files is not necessarily allocated at file creation time.

Action: Restore access to the device or remove unnecessary files to free up space.

ORA-01114是一个Oracle错误，表明数据库实例在写入到字段时，无法写入该字段的某个块，称为写块。根据官方文档，是因为实例数据文件必须在磁盘上，但当前没有足够可用的空间可用来满足最低限度的写入空间要求。

常见案例

正常处理方法及步骤

1）检查表空间大小，把它调整到至少一个块比正常文件大小更大的大小。

2）检查正在写入的文件的大小，确认它的大小也至少是一个块的大小更大的大小。

3）检查SGA_MBX_BLOCK_SIZE参数，确保它的大小不小于一个块

4）检查硬盘空间，如果不足，需要增加空间

5）重新启动数据库
