list archivelog all 是列出控制文件中记录的未被rman delete 命令删除的手工删除的日志文件，如果手工删除之后使用list命令对应的日志文件的status为标记为X！
模拟删除日志yangdb_1_192_762800109.log
oracle@rac3:/opt/oracle/yangdb_arch>mv yangdb_1_192_762800109.log /tmp/
crosscheck 命令检查归档日志的信息：
RMAN> crosscheck archivelog all;
released channel: ORA_DISK_1
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=39 device type=DISK
validation failed for archived log
archived log file name=/opt/oracle/yangdb_arch/yangdb_1_192_762800109.log RECID=188 STAMP=770308389
validation succeeded for archived log
archived log file name=/opt/oracle/yangdb_arch/yangdb_1_193_762800109.log RECID=189 STAMP=770308806
validation succeeded for archived log
再次使用list archivelog all; mv掉的日志被标记为X。
