Boomi 计时器中的 uCanAccess 错误已取消

Question

我们正在使用 Boomi 在数据库和 MS Access 数据库之间进行集成。我们使用 uCanAccess 作为 JDBC，因此我们可以 read/write MS Access 数据库。

但是，如果我们的初始查询 returns 超过 49 行，我们会收到来自 Boomi 和 uCanAccess 的以下错误。我尝试使用流控制以便一次只处理 10 个文档，但这没有用。同样的错误。我尝试更改批次计数。没有什么。

Test execution of RYN-EMPDATA-BadgeDB completed with errors. Embedded message: Timer already cancelled.

Error Screen Shot

uCanAccess site 带有推荐的 Jackcess 和 HSQLDB 版本的 3.0.6 版本

插入操作成功，但更新操作失败。我们正在使用从访问文件导入的动态更新数据库配置文件。

一些新信息。原来失败来自特定的记录。我认为它在抱怨传递了 NULL 值，但我不能 100%

这是 Java 错误的顶部：

9/6 经过大量测试，问题的原因与获取其中一个字段中包含二进制数据的字段有关。我们没有更新该字段，但出于某种原因，一旦 uCanAccess 命中包含二进制数据（程序存储的照片）的行，它就会失败。

这是尝试通过 uCanAccess 控制台更新相同记录的输出：

    UCanAccess>update badgelisting set firstname="Test", lastname="stuff", active="false" where idnumber=58;

UCanAccess>UCAExc:::3.0.6 null

Answer 1

很多这都归结为时机。如果有人在处理之前就在数据库中，我会得到错误。此外，我不得不将处理过程分解为 30 个项目。然后我必须设置一个进程，在每个运行之后运行一个 compact/repair，因为它使数据库膨胀了大约 30%。

至于 Boomi，写入 AccessDB 应该是一项简单的任务。我不应该为了完成这件事而恢复到 UCanAccess。
