1.1.1.5 知识点
1.使用CONFIGURE RETENTIONPOLICY TO RECOVERY WINDOW命令。
例如：RMAN>CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 5 DAYS;
我现在的时间是6月11日16:42，如果我设置了上述备份保留策略并进行备份，则该备份在6月16日16:42之后会被标识为废弃。
2.使用CONFIGURE RETENTION POLICYREDUNDANCY命令。
例如：RMAN>CONFIGURE RETENTION POLICYREDUNDANCY 3;
如果进行了上述设置，当完成三次备份后，在做完第四次备份的时候，第一次备份结果将被标识为废弃。ORACLE11G默认的备份保留策略是用该方法设置的，且REDUNDANCY为1。可以使用命令CONFIGURE RETENTION POLICY CLEAR恢复策略为默认值。还可以用命令CONFIGURE RETENTION POLICY TO NONE进行策略设置，此时REPORT OBSOLETE和DELETE OBSOLETE将不把任何备份文件视为废弃。
3.ORACLE备份目录由db_recovery_file_dest参数设置
4.ORACLE备份目录由db_recovery_file_dest_size参数设置
