接到客户反馈，致命终止用户把生产NC数据库导出之后，错误在测试库无法成功导入。致命终止在导入过程中遇到错误被终止。错误错误代码是致命终止ORA-7445[kpodpals],由于提供的信息量比较少，刚开始没有头绪，错误这个问题处理起来还是致命终止挺麻烦的。

步骤一：分析跟踪日志信息

通过对跟踪日志的亿华云错误分析，查看问题的致命终止故障点。通过分析跟踪日志，错误查找问题出现的致命终止原因。跟踪日志文件，错误内容具体如下：

步骤二：通过故障代码的分析，查找ORACLE官方相关文档。错误

通过对跟踪日志的网站模板致命终止分析，我们发现ORACLE 报ORA-07445 [kpodpals()+5174]，我们这里就抓住ORA-07445 [kpodpals()+5174]

不放，这种核心错误，一般99%是Oracle的BUG引起，通过Oracle的官方信息，果然发现了一篇文档：
