之前的文档：Oracle 异机恢复 - 仅仅恢复业务表空间_rman-06067: recover database required with a backu-CSDN博客
参考文档：
How to Recover From a DROP / TRUNCATE / DELETE TABLE with RMAN (Doc ID 223543.1)
d. Restore of the necessary tablespaces, RESTORE TABLESPACE:
https://docs.oracle.com/en/database/oracle/oracle-database/19/rcmrf/RECOVER.html
Example 3-3 Performing DBPITR with a Backup Control File and Recovery Catalog
本测试，只恢复部分表空间，system、sysaux、undotbs、业务TBS。
和之前的测试，不同的地方，之前的测试，restore所需的表空间，在recover之前，使用重建控制文件的方式，将控制文件中不需要的表空间文件排除掉。
现在的测试方式，restore所需的表空间，在recover之前，不需要重建控制文件，在recover的时候，使用recover database skip forever tablespace XXX ,排除掉不需要recover的database，然后开库。
测试过程
1 restore ctl
2 restore 必须的表空间，指定了until time
3 不需要重新创建控制文件，在recover的时候脚本中排除掉不需要recover的表空间 ，指定until time进行recover
4 禁用触发器，加TEMP表空间
