Oracle归档日志过多导致磁盘空间不足问题处理

2022-11-22 分类：AI转载阅读(145)

概述

由于Oracle归档日志过多导致系统磁盘空间不足，从而导致无法连接Oracle数据库，执行sql语句报错。

ORA-00257: archiver error. Connect internal only, until freed.
 
SP2-0306: Invalid option.
Usage: CONN[ECT] [{logon|/|proxy} [AS {SYSDBA|SYSOPER|SYSASM}] [edition=value]]
where  ::= [/][@]
       ::= [][/][@]
Enter password:
ERROR:
ORA-01005: null password given; logon denied
 
SP2-0157: unable to CONNECT to ORACLE after 3 attempts, exiting SQL*Plus

解决办法

查看Free_MB空间

[oracle@db1 ~]$ su - grid
Password: grid
[grid@db1 ~]$ asmcmd

删除Free_MB空间

打开控制文件

[oracle@db1 ~]$ sqlplus "/as sysdba"
  startup mount

删除归档

删除一天前的归档

[oracle@db1 ~]$ rman target /
RMAN> delete noprompt archivelog all completed before 'sysdate-1';

修改数据库状态为打开

[oracle@db1 ~]$ sqlplus / as sysdba
SQL>  alter database open;

其他

查看归档日志信息

Oracle归档空间日志文件位置根据Archive destination判断。

[oracle@db2 ~]$  sqlplus / as sysdba
SQL> archive log list;
Database log mode              Archive Mode
Automatic archival             Enabled
Archive destination            /u01/app/oracle/11.2.0.3/dbs/arch
Oldest online log sequence     976392
Next log sequence to archive   976393
Current log sequence           976393
