1、删除归档日志
$rman target /
RMAN> list archivelog all;
RMAN>crosscheck archivelog all;
RMAN>change archivelog until logseq=130 thread=1 delete;
或者 RMAN>delete expired archivelog all;
2、取消闪回恢复区
alter system set db_recovery_file_dest='';
3、更改归档日志路径
show parameter db_recover;
archive log list;
alter system set log_archive_dest_1='location=+DATA1' sid='*' scope=both;
