背景

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。

问题分析

步骤一：分析跟踪日志信息

通过对跟踪日志的错误分析，查看问题的致命终止故障点。通过分析跟踪日志，查找问题出现的原因。跟踪日志文件，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。

通过对跟踪日志的分析，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：
ORA-7445 [kpodpals] During DataPump Import (文档 ID 1096837.1)
