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

问题现象

使用navicat连接oracle时无法连接上去，提示这个错误

问题原因

归档日志占用空间满了，注意这里分为两个

硬盘空间不足了
硬盘空间足够但是归档日志空间不够了

解决方案

针对第一种情况，拓展本地硬盘空间，或删除之前日志
针对第二种情况，需要设置归档日志大小，或删除归档日志

连接到SQL查询归档状态

操作说明

复制代码

1.查看归档路径
archive log list;
Arcive destination      USE_DB_RECOVERY_FILE_DEST
此参数代表归档存放路径，本地存放为/opt/oracle...，asm为+archdg
当为以上参数时，代表存放到数据闪回区

2.查看闪回区设置
show parameter recover;

db_recovery_file_dest  #表示存放路径
db_recovery_file_dest_size  #表示可以使用的空间大小


3.设置闪回区大小
alter system set db_recovery_file_dest_size=100G scope=both;


4.查看归档空间使用情况
select * from v$flash_recovery_area_usage;


查看闪回区是否开启

select flashback_on from v$database;

开启闪回
SQL>shutdown immediate;
SQL>startup mount;
SQL>alter database archivelog;
SQL> alter database flashback on;

关闭闪回
SQL>shutdown immediate；
SQL>startup mount;
SQL>alter database flashback off;

切换到rman删除归档日志
