rman恢复异常，归档日志损坏

ALLSTARS_ORACLE

最近生产库表被truncate，生产库通过nbu备份到带库，于是决定通过nbu将数据库在异机进行恢复，恢复过程中，控制文件和数据文件都是可以正常restore的，当开始恢复归档日志并且应用时，总是出现异常，
rman恢复的错误日志如下：

但是这些归档日志确实已经恢复到到了/arch/archlog1的归档存放目录，在生产库我尝试对这些归档进行logmnr，也是可以执行的。
求教各位大神，是否有解决方案


list backup发现此备份有效

这个数据库是每周六一次全备，之后每日增备，我是想恢复到8月11日的上午，使用的是8月11日早上增量备份结束后的控制文件备份集来恢复的控制文件，应该已经包含了这次归档的备份信息
请教大神，我是什么地方搞错了吗



我在使用validate backupset来校验最近2天的备份集时，也是出现错误
RMAN> validate backupset 21013;

using channel ORA_DISK_1
using channel ORA_DISK_2

但是该备份集看起来状态有效

但是我手工掏归档是可以将这些归档日志恢复出来的，并没有说找不到备份集，命令如下：
run
{ allocate channel t1 type 'sbt_tape';
send 'NB_ORA_SERV=RLZY,NB_ORA_CLIENT=hbdb1';
SET ARCHIVELOG DESTINATION TO '/arch/archlog1';
restore archivelog from logseq  83213 until logseq 83215 thread 1  ;
release channel t1;
}
也可以list这个备份集


RMAN> list backupset 20637;

using target database control file instead of recovery catalog

想使用recover指定归档日志进行恢复，也是有错误
