Oracle错误ORA-03113: end-of-file on communication channel处理办法

Posted 2020-08-09

oracle不能启动了，报错ORA-03113: end-of-file on communication channel （通信通道的文件结尾）

解决办法：

SQL> startup
ORACLE instance started.
 
Total System Global Area 1252663296 bytes
Fixed Size 2227944 bytes
Variable Size 704643352 bytes
Database Buffers 536870912 bytes
Redo Buffers 8921088 bytes
Database mounted.
ORA-03113: end-of-file on communication channel
Process ID: 8117
Session ID: 191 Serial number: 3
网上分析，可能由于昨晚数据库强制关闭，导致文件状态可能不一致，因为正常关闭数据库会同步校验各文件，使得重新启动的时候文件时间点一致。解决方案如下
启动DB
SQL> conn / as sysdba
Connected to an idle instance.
 
SQL> startup mount
ORACLE instance started.

SQL> select * from v$log;
 
    GROUP# THREAD# SEQUENCE# BYTES BLOCKSIZE MEMBERS ARC

SQL> alter database open resetlogs 2;
alter database open resetlogs 2
                              *
ERROR at line 1:
ORA-02288: invalid OPEN mode
恢复数据库
SQL> alter database open resetlogs;
alter database open resetlogs
*
ERROR at line 1:
ORA-01139: RESETLOGS option only valid after an incomplete database recovery
 
 
SQL> recover database until time ‘2016-08-05‘
Media recovery complete.
SQL> alter database open resetlogs;
 
Database altered.
成功。
