碰到一个问题specification does not match any foreign archived log in the repository
原因如下:
因为控制文件最多存储100个归档日志,如果之前,没有部署好清理归档的任务的话,导致旧的归档日志无法被删除.比如2个月之前的归档日志就无法被删除.这样导致目录消耗过大.
检查方法：
list archivelog 'D:ORACLEPRODUCT10.2.0FLASH_RECOVERY_AREAV10203ARCHIVELOG2007_11_13O1_MF_1_6_3MM4NR1W_.ARC';
list archivelog all;
详细查看RMAN-20242 failure at RMAN Backup Archivelog - possible Cause and Solution (文档 ID 1634498.1)
解决方法
方法1:
脚本里加入
catalog start with 'C:APPORACLEARCHIVELOG' noprompt ;
方法2:
及时备份脚本,定时任务清理归档.
1/ windows（如果没有使用管理员用户创建定时任务，那么需要在 定时任务 属性里，选择 安全选项，选择最高权限 执行 ），确保定时任务可以在windows 下正常运行。
2.建议使用administrator 创建定时任务，创建数据库，分c,d 盘。
