ORACLE中使用RAMA删除部分日志

Oracle 前端之家
前端之家收集整理的这篇文章主要介绍了ORACLE中使用RAMA删除部分日志，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。

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


  1. [oracle@oracledb ~]$ rman
  2.  
  3. Recovery Manager: Release 11.2.0.4.0 - Production on Fri Jan 20 07:05:17 2017

  7. RMAN> connect target sys/oracle
  8.  
  9. connected to target database: ORCL (DBID=1460481228)
  10.  
  11. RMAN> list archivelog all;
  12.  
  13. using target database control file instead of recovery catalog
  14. List of Archived Log Copies for database with db_unique_name ORCL

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

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

4.执行以下语句删除expired状态的日子文件：

  1. RMAN> delete expired archivelog all;

  15. Do you really want to delete the above objects (enter YES or NO)? YES
  16. deleted archived log
  17. archived log file name=/u01/oracle/oralog/ARC0000000010_0932700493.0001_570d2ccc.log RECID=3 STAMP=933493501
  18. Deleted 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；
