ora-00257|ora-00257 :归档日志满

解决操作:
登录rman 并记录日志
rman target / d:\log\rman_log.txt
【ora-00257|ora-00257 :归档日志满】进入rman,查看归档状态:list archivelog all;
crosscheck archivelog all;
手工删除7天以前得日志记录:delete archivelog all completed before 'sysdate-1';
备份到指定位置:backup database format 'D:/backup/data/bk_db_%T_%U' plus archivelog format 'D:/backup/log/bk_log_%T_%U';
