ORA-30375错误是由于物化视图的数据不新鲜时出现的。官方解释如下：

ORA-30375: materialized view cannot be considered fresh

Cause: An attempt was made to create a materialized view with a size limit that would require deleting some rows from its table in order to ensure that its contents is fresh.

Action: Increase the size limit so that the materialized view can always be considered fresh.

一般处理方法及步骤

1. 检查错误的触发原因，是否可能会出现删除视图记录的情况。

2. 如果确定触发原因，则使用alter语句修改物化视图的大小限制。

3. 重新执行物化视图操作，查看是否能正常创建物化视图。
