oracle联机重做日志文件丢失&&&&Oracle错误ORA-03113: end-of-file on communication channel处理办法

一：　1.  在oracle正常运行过程中，强行删除联机重做数据库，而后强制关闭数据库

SQL> host rm -rf '/u01/oradata/orcl/redo01.log'

SQL> shutdown abort;
ORACLE instance shut down

2.而后重启数据库，出现如下错误

SQL> startup
ORACLE instance started.

Total System Global Area  835104768 bytes
Fixed Size		    2217952 bytes
Variable Size		  528484384 bytes
Database Buffers	  301989888 bytes
Redo Buffers		    2412544 bytes
Database mounted.
ORA-03113: end-of-file on communication channel
Process ID: 12350
Session ID: 1 Serial number: 5

 

此时应以mount方式启动数据库

SQL> startup mount
ORACLE instance started.

Total System Global Area  835104768 bytes
Fixed Size		    2217952 bytes
Variable Size		  528484384 bytes
Database Buffers	  301989888 bytes
Redo Buffers		    2412544 bytes
Database mounted.
SQL> alter database clear logfile group 1;

Database altered.

SQL> alter database open;

 

 

二，　以shutdown abort 形式关闭数据库，而后重启数据库，Oracle错误ORA-03113: end-of-file on communication channel处理办法
