impdp因致命错误终止ORA-7445[kpodpals]
基本要素前天好不容易成功给用户把数据全库导出，今天用户又告知导出的数据无法导入，首先就问用户有什么错误提示，给我的回答是就一个‘作业"SYSTEM"."SYS_IMPORT_FULL_03" 因致命错误于 xxxx elapsed 0 03:01:06 停止’,其他什么提示都没有，信息量太少了，这个处理起来还挺麻烦的。
问题分析
步骤一：首先还是添加跟踪信息
还是得靠自己，还好咱们会点跟踪技巧，具体方法见我之前的文章How to Diagnose Oracle Data Pump-如何给数据泵添加诊断信息，来吧，看下跟踪后的结果orcl_dm00_10856.trc，错误提示的位置如下：
KUPM:13:38:03.378: Log message received from worker DG,KUPC$C_1_20141208103757,KUPC$A_1_103800203000000,MCP,510,Y KUPM:13:38:03.378: . . 导入了 "ZLHIS"."体检套餐计价" 576.4 KB 20817 行 KUPM:13:38:03.378: ****OUT DISPATCH, request type=3031, response type =2041 *** 2014-12-08 13:38:04.392 KUPM:13:38:04.392: Client count is: 1 KUPM:13:38:04.392: In check_workers...

结果非常令人失望，也没什么有价值的错误提示。
步骤二：查看下alert日志
这时候想到查看下alert日志，也许里面能给一些提示，打开日志果然发现了非常有价值的信息，如下：
