RMAN> backup database format '/db/backup/data%U' plus archivelog format '/db/backup/arch%U' delete input;
控制文件备份名称/db/backup/data2bsepba0_1_1
最后一个归档日志序号为8的备份名称/db/backup/arch2csepba3_1_1

SQL> alter system archive log current;--9
SQL> alter system archive log current;--10
SQL> alter system archive log current;--11
SQL> alter system archive log current;--12

RMAN> list archivelog all;--有9、10、11、12归档日志

RMAN> list backup;有最后8号归档日志的备份包
SQL> shutdown immediate;

控制文件没有最后一个归档日志备份包，怎么恢复
--通过catalog手工添加
控制文件中没有控制文件备份之后的归档日志，oracle怎么识别新增的归档日志(没有9-12号归档日志)
--oracle会自动根据log_archive_format、log_archive_dest_1参数去寻找sequence为9开始的归档日志
SQL> startup nomount;
RMAN> restore controlfile from '/db/backup/data2bsepba0_1_1';
RMAN> alter database mount;
RMAN> list backup;--没有8号归档日志的备份包
RMAN> catalog backuppiece '/db/backup/arch2csepba3_1_1';--添加8号归档日志的备份包
RMAN> list backup;--有8号归档日志的备份包
RMAN> restore archivelog sequence 8;
RMAN> list archivelog all;--没有9-12归档日志
RMAN> recover database;--会自动找到9-12号日志进行恢复

RMAN> list archivelog all;
