ORA-00257: archiver error. Connect internal only, until freed.

错误很明显，直接可以跳过告警日志的查看

查看归档日志路径

1.本地登录

sqlplus / as sysdba

2.查看归档日志的位置

已经使用了99.02了

SQL> select sum(percent_space_used)*3/100 from v$flash_recovery_area_usage;

空间使用了2.9706

SUM(PERCENT_SPACE_USED)*3/100
-----------------------------
2.9706

由于归档日志使用的是默认的目录

闪回区flash_recovery_area的db_recovery_file_dest下面

SQL> show parameter db_recover

NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
db_recovery_file_dest string /u01/oracle/fast_recovery_area
db_recovery_file_dest_size big integer 4122M

路径：

[oracle@oracle2 ~]$ ls /u01/oracle/fast_recovery_area/PU/archivelog/
2016_05_17 2016_05_18 2016_05_19

大小

[oracle@oracle2 ~]$ cd /u01/oracle/fast_recovery_area/PU/archivelog/
[oracle@oracle2 archivelog]$ ls |xargs du -sm
506 2016_05_17

506M 2016_05_17
3.5G 2016_05_18
4.0K 2016_05_19

解决办法的

1、加大闪回区的大小（除非你的磁盘空间很大）

SQL> alter system set db_recovery_file_dest_size=8192m;

System altered.

SQL> show parameter db_reco

NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
db_recovery_file_dest string /u01/oracle/fast_recovery_area
db_recovery_file_dest_size big integer 8G

2、转移或者清除归档日志（无论转移或者删除，都要使用rman维护，否则会导致控制文件记录的seq不一致，不释放空间）

这里我们使用转移的方法

mv 2016_05_18/ /u01

root@oracle2 ~]# ls /u01/2016_05_18/ |wc -l
79

一共79个归档日志文件

rman target /

RMAN> crosscheck archivelog all; 检查过期的归档日志

RMAN> delete expired archivelog all; 删除过期的归档日志

Deleted 79 EXPIRED objects 一共79个被删除

SQL> select * from V$FLASH_RECOVERY_AREA_USAGE;

3、修改归档日志的路径

alter system set log_archive_dest_1='location=/u01/archivelog' scope=spfile;
