1开归档
[root@db1 ~]# mkdir -p /home/oracle/arch
[root@db1 ~]# chown -R oracle.dba /home/oracle/arch
[root@db1 ~]# chmod -R 755 /home/oracle/arch
同时也在备库上面创建相应的目录存放归档
root@DB ~]# mkdir -p /home/oracle/arch
[root@DB ~]# chown -R oracle.dba /home/oracle/arc
chown: cannot access `/home/oracle/arc': No such file or directory
[root@DB ~]# chown -R oracle.dba /home/oracle/arch
[root@DB ~]# chmod -R 755 /home/oracle/arch
