Java Jasper报告错误：ORA-01555:快照太旧：名称为“的回滚段编号”&引用；太小ORA-22924:快照太旧

当我使用Jasper作为接口时，有时接口调用Jasper并生成报告，然后我们得到如下异常：

在数据库中，没有出现ORA-015555和ORA-22924。我们将undo_保留参数增加到8小时，但仍然存在问题

有没有人以前遇到过这个问题，有什么解决办法

可能您试图一次读取太多LOB。 如果是，那么

尝试重新定义要读取的示例LOB（可能的原因是从具有多个LOB的表\U中选择*。删除该LOB，问题就解决了。）

尝试增加保留区大小（读取）

尝试调整用于保留每列保留数据的默认存储百分比。像

更改表您的LOB表修改LOB（LOB列名称）（PCTVERSION 50）

比如说。

希望这有帮助）

这是一个关于这个问题的非常好的页面：

Oracle使用回滚段存储数据库中更改的数据 交易如果出现以下情况，此数据用于恢复原始数据： 回滚发生在事务中

此外，回滚段中的数据用于保证 阅读一致性。也就是说，一个查询总是看到相同的数据 虽然它可能在查询的中间被修改。

如果回滚段空间不足，则会出现ORA-01555

您使用的是什么Oracle版本？事实上，我认为这个问题与Oracle版本无关。请注意，答案应该是搜索解决方案的终点（而不是另一个参考的中途停留，随着时间的推移，它往往会过时）。请考虑在这里添加一个独立的概要，将链接作为参考。
