[oracle@oracle-n1 ~]$ sqlplus "/as sysdba"

SQL> shutdown immediate;

2.启动数据库到mount状态

二.查看和修改归档参数

1.修改存放归档路径位置

SQL> alter system set log_archive_dest_1='location=/arp/oraarp/oradata/arpdb/archivelog';

2.查看归档路径位置明细

SQL> show parameter log_archive_dest_1

NAME                                 TYPE        VALUE

------------------------------------ ----------- ------------------------------

log_archive_dest_1                   string      location=/arp/oraarp/oradata/a
