ORACLE中使用RAMA删除部分日志

1.登陆RAMA并查看相关日志文件
rman
connect target sys/oracle
list archivelog all

2.发现有key从3到16的日志文件，现在我们来删除几个，手工到归档路径删除几个归档日志文件

[root@oracledb ~]# su - oracle[oracle@oracledb ~]$ rm /u01/oracle/oralog/ARC0000000010_0932700493.0001_570d2ccc.log

以上可知，recid=3的文件validation failed for archived log

3.再次查看是否还有已删除日志文件的记录发现依然还存在列表中

RMAN> list archivelog all;List of Archived Log Copies for database with db_unique_name ORCL=====================================================================Key     Thrd Seq     S Low Time           ------- ---- ------- - -------------------3       1    10      X 2017-01-17 07:43:53        Name: /u01/oracle/oralog/ARC0000000010_0932700493.0001_570d2ccc.log4       1    11      A 2017-01-17 07:45:00        Name: /u01/oracle/oralog/ARC0000000011_0932700493.0001_570d2ccc.log5       1    12      A 2017-01-17 08:10:51        Name: /u01/oracle/oralog/ARC0000000012_0932700493.0001_570d2ccc.log6       1    13      A 2017-01-17 08:16:51        Name: /u01/oracle/oralog/ARC0000000013_0932700493.0001_570d2ccc.log7       1    14      A 2017-01-18 01:26:22        Name: /u01/oracle/oralog/ARC0000000014_0932700493.0001_570d2ccc.log8       1    15      A 2017-01-18 07:19:54        Name: /u01/oracle/oralog/ARC0000000015_0932700493.0001_570d2ccc.log9       1    16      A 2017-01-18 21:48:33        Name: /u01/oracle/oralog/ARC0000000016_0932700493.0001_570d2ccc.log10      1    17      A 2017-01-18 21:52:13        Name: /u01/oracle/oralog/ARC0000000017_0932700493.0001_570d2ccc.log11      1    18      A 2017-01-18 21:57:10        Name: /u01/oracle/oralog/ARC0000000018_0932700493.0001_570d2ccc.log12      1    19      A 2017-01-18 22:01:34        Name: /u01/oracle/oralog/ARC0000000019_0932700493.0001_570d2ccc.log13      1    20      A 2017-01-18 22:06:37        Name: /u01/oracle/oralog/ARC0000000020_0932700493.0001_570d2ccc.log14      1    21      A 2017-01-19 06:24:46        Name: /u01/oracle/oralog/ARC0000000021_0932700493.0001_570d2ccc.log15      1    22      A 2017-01-19 06:30:16        Name: /u01/oracle/oralog/ARC0000000022_0932700493.0001_570d2ccc.log16      1    23      A 2017-01-19 06:35:43        Name: /u01/oracle/oralog/ARC0000000023_0932700493.0001_570d2ccc.log

4.执行以下语句删除expired状态的日子文件：

RMAN> delete expired archivelog all;released channel: ORA_DISK_1allocated channel: ORA_DISK_1channel ORA_DISK_1: SID=60 device type=DISKList of Archived Log Copies for database with db_unique_name ORCL=====================================================================Key     Thrd Seq     S Low Time           ------- ---- ------- - -------------------3       1    10      X 2017-01-17 07:43:53        Name: /u01/oracle/oralog/ARC0000000010_0932700493.0001_570d2ccc.logDo you really want to delete the above objects (enter YES or NO)? YESdeleted archived logarchived log file name=/u01/oracle/oralog/ARC0000000010_0932700493.0001_570d2ccc.log RECID=3 STAMP=933493501Deleted 1 EXPIRED objects

注意执行删除时会进行询问，输入YES执行删除.

5.使用list archivelog all;再次查看时发现手工删除的日子文件已消失在此列表中了；
