环境: OEL 5.7 + Oracle 11.2.0.4 1.直接restore到想要恢复的时间点报错:
RMAN> sql "alter session set nls_date_format=''yyyy-mm-dd hh24:mi:ss''"; RMAN> restore database until time '2018-06-26 09:00:00'; Starting restore at 2018-06-27 07:30:04 using channel ORA_DISK_1 using channel ORA_DISK_2 using channel ORA_DISK_3 using channel ORA_DISK_4 using channel ORA_DISK_5 using channel ORA_DISK_6 RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571: =========================================================== RMAN-03002: failure of restore command at 06/27/2018 07:30:04 RMAN-20207: UNTIL TIME or RECOVERY WINDOW is before RESETLOGS time
2.查看incarnation,尝试RESET DATABASE TO INCARNATION也不行:
RMAN> list incarnation; List of Database Incarnations DB Key Inc Key DB Name DB ID STATUS Reset SCN Reset Time ------- ------- -------- ---------------- --- ---------- ---------- 1 1 ORCL 1507617844 PARENT 1 2013-08-24 11:37:30 2 2 ORCL 1507617844 CURRENT 925702 2018-06-26 16:58:31 RMAN> RESET DATABASE TO INCARNATION 1; database reset to incarnation 1 RMAN> restore database until time '2018-06-26 09:00:00'; Starting restore at 2018-06-27 07:30:40 using channel ORA_DISK_1 using channel ORA_DISK_2 using channel ORA_DISK_3 using channel ORA_DISK_4 using channel ORA_DISK_5 using channel ORA_DISK_6 RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571: =========================================================== RMAN-03002: failure of restore command at 06/27/2018 07:30:40 RMAN-06026: some targets not found - aborting restore RMAN-06023: no backup or copy of datafile 4 found to restore RMAN-06023: no backup or copy of datafile 3 found to restore RMAN-06023: no backup or copy of datafile 2 found to restore RMAN-06023: no backup or copy of datafile 1 found to restore RMAN> list backup of database; specification does not match any backup in the repository
此时catalog start with 之前的全备也不认。 思考一下。。 3.恢复一个incarnation之前的控制文件来尝试恢复:

可以成功恢复。
