SQL>recover database; 该命令用来对所有数据文件进行恢复，只能使用保存在文件系统上的归档日志及在线日志。使用此类命令的前提是控制文件不可以是还原或重建得来的。 SQL>recover database until sequence XX;--SQL没有这样的写法，会报错ORA-00277: illegal option to the UNTIL recovery flag SEQUENCE
2 SQL>recover database using backup controlfile; 该命令用来对所有数据文件及控制文件进行恢复，只能使用保存在文件系统上的归档日志及在线日志。
三者关于Specify log: {=suggested | filename | AUTO | CANCEL}提示的区别 RMAN不会有这样的提示，所以RMAN>recover database until cancel会报错
SQL>recover database until cancel;会带出如下Specify log: {=suggested | filename | AUTO | CANCEL}信息
SQL>recover database using backup controlfile;会自动带出Specify log: {=suggested | filename | AUTO | CANCEL}信息
输入filename表示输入具体的归档日志进行recover(current redo日志丢失的时候，filename就是对应 current redo日志的路径)，如下案例85提示显示为归档日志，但是current redo日志，所以输入/db/oracle/oradata/PROD1/redo01.log 输入AUTO表示主动recover直到最后一个归档日志 SQL> recover database until cancel; ORA-00279: change 2292679 generated at 07/31/2017 14:26:21 needed for thread 1 ORA-00289: suggestion : /db/oracle/fast_recovery_area/PROD1/archivelog/2017_07_31/o1_mf_1_85_%u_.arc ORA-00280: change 2292679 for thread 1 is in sequence #85
