报错如下，原因是存放传过来的归档的目录+HWAREDODG满了，MRP进程无法应用归档，我在手动传了几个归档之后发现不是GAP，select * from V$ARCHIVE_GAP 显示没有GAP。于是就把HWAREDODG下已经应用的归档删掉，
rman target /
rman>select ‘run{‘ from dual
union all
select ‘delete noprompt archivelog until sequence ‘||max(sequence#)||‘ thread ‘||thread#||‘;‘ from v$archived_log where applied=‘YES‘ and name is not null GROUP BY thread#
union all
select ‘}‘ from dual;
删除后归档顺利生成，MRP进程正常应用

Check that the CONTROL_FILE_RECORD_KEEP_TIME initialization
parameter is defined to a value that‘s sufficiently large
enough to maintain adequate log switch information to resolve
archivelog gaps.
