这里分析，未发现任何错误，导出程序直接报Segmentation fault终止
原因分析
通过各种方式导入都报类似错误，初步确定是dmp文件异常，而dmp异常有几种可能性：
1.exp程序异常导致dmp文件异常，这里使用tns方式导出，排除该种可能
2.数据库内存出现异常导致dmp文件异常，重启数据库依旧，排除该种可能
3.因为测试过多种平台，版本，本地，远程导入，排除兼容性，远程传输损坏等
4.因为以前正常，突然异常，坏可以exp程序调用包异常，这种故障不能排除
解决方案
鉴于此，通过expcat.sql重新安装相关包，发现执行这个之后，exp导出程序，再imp导入一切正常
执行catexp.sql不影响生产库，只影响exp/imp程序
conn / as sysdba
@?/rdbms/admin/catexp.sql
这里再次提醒我们看到exp导出成功,不能证明imp一定ok,最好通过imp进行导入测试
