查看alert日志发现,有多处ora-19815,其实日志就提供了解决方法。
又在网上看了一下,感谢http://www.eygle.com/archives/2005/03/oracle10gecieif.html
ORA-19815: WARNING: db_recovery_file_dest_size of 2147483648 bytes is 100.00% used, and has 0 remaining bytes available.
*************************************************************
You have the following choices to free up space from
flash recovery area:
1. Consider changing your RMAN retention policy.
   If you are using dataguard, then consider changing your
   RMAN archivelog deletion policy.
2. Backup files to tertiary device such as tape using the
   RMAN command BACKUP RECOVERY AREA.
3. Add disk space and increase the db_recovery_file_dest_size
   parameter to reflect the new space.
4. Delete unncessary files using the RMAN DELETE command.
   If an OS command was used to delete files, then use
   RMAN CROSSCHECK and DELETE EXPIRED commands.
*************************************************************

这时候实际上flash_recovery_area已经手工释放空间,甚至切换到一个全新的磁盘,仍然无法解决。
连接数据库查询:

Oracle指出,我们可以通过执行以下命令:
RMAN> backup recovery area;


将闪回区的内容备份到第三方介质,也同样可以解决这个问题。
是以为记。
