immediate;
startup mount;
alter database noarchivelog;
alter database open;
shutdown immediate;
再次startup以archive log模式
shutdown immediate;
startup mount;
show parameter log_archive_dest;
alter database archivelog;
archive log list;
alter database open;
如果还不行，则删除一些archlog log
SQL> select group#,sequence# from v$log;
GROUP# SEQUENCE#
---------- ----------
1 62
3 64
2 63
原来是日志组一的一个日志不能归档
SQL> alter database clear unarchived logfile group 1;
alter database open;
最后，也可以指定位置Arch Log, 请按照如下配置
select name from v$datafile;
alter system set log_archive_dest='/opt/app/oracle/oradata/usagedb/arch' scope=spfile
或者修改大小
SQL> alter system set db_recovery_file_dest_size=3G scope=both;
