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
