我正在开发一个 Oracle11gR2 数据库。数据库处于 DataGuard 模式，即使 dataguard 设置为 DEFER。
我想删除已至少备份 2 次到磁带的所有归档日志。
rman> list archivelog all backed up 2 times to device type sbt_tape;
显示符合条件的归档日志列表
但是，当我稍后尝试运行时
rman> delete force noprompt archivelog all backed up 2 times to device type sbt_tape;
没有文件被删除。
除了设置为 370 天窗口的保留策略外，所有参数均设置为默认值
查看我生成的跟踪，除其他外，显示list命令报告的每个文件的此消息
DBGMISC: Matching archived log has 0 backups
我不知道如何解释。
任何有关如何进一步调查该问题的想法将不胜感激
rman配置如下
using target database control file instead of recovery catalog
