文档解释

ORA-27046: file size is not a multiple of logical block size

Cause: file size as indicated by stat is not correct, additional information indicates which function encountered the error

Action: verify that the file has not been overwritten or truncated

ORA-27046是一个数据库错误代码，它指示文件大小不是块大小的整数倍。例如，假设逻辑块大小为512字节，而文件大小为513字节。换句话说，当文件不能够被按块大小均匀地分割和分配时，就会出现此错误。

官方解释

“ORA-27046：文件大小不是逻辑块大小的整数倍。”

常见案例

该错误常常发生在使用Data Pump导入大量数据时，Data Pump因大文件不能适应当前的逻辑块大小，而报出ORA-27046错误。

一般处理方法及步骤

1. 检查文件大小和逻辑块大小的关系。

2. 修改逻辑块大小以适合文件大小。

3. 再次运行Data Pump导入操作。
