上周在使用TTS传输表空间从11.2.0.4到19C， 在最后impdp metadata的环节提示ora-942 结果提示有大量索引没有创建成功，但是查看报错的表实际是存在的， 后来发现这是一个收权问题导致的。后分析这种场景是发生在如一开始给了一个用户如create ANY table/index的系统权限或者dba 角色或是on object上的权限，后来创建了跨SCHEMA的index（indexes and tables differenct owners）或FK 约束时，再后来安全整改收回大权限，就导致了这个问题。 下面验证一下。
创建表空间、用户、表和索引

Note:
我们在两个用户创建了一个表，又分别在对方的表上创建了跨schema的索引和本schema索引，一并排除是按导入schema顺序导致和是否所有索引都有问题。

Note:
这里你会发现导入的数据中少了两个index和table owner不同的索引，相同schema的索引创建成功。当然我expdp的用户anbob是DBA 角色，不存在导入用户的权限不足。
如果u1/u2 用户不收回create any index系统权限再次做相同的测试
这里省略了相同的数据构建部分，只是没有收回create any index权限。

Note:
导入是成功的。
警示：
以后在TTS前需要检查index和table owner不相同的对象，并检查该user是否权限满足，可以临时授予DBA或CREATE ANY INDEX的权限，导入成功后回收权限即可。
