Oracle错误ORA-03113: end-of-file on communication channel处理办法
机器遭遇断电,之后oracle就不能启动了,报错ORA-03113: end-of-file on communication channel (通信通道的文件结尾)
SQL> startup
ORACLE instance started.

ORA-03113: end-of-fileon communication channel

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.
直接reset不成功
SQL> select* from v$log;
SQL> alterdatabase open resetlogs;
alter database open resetlogs
*
ERROR atline 1:
ORA-01139: RESETLOGSoption onlyvalid after an incomplete database recovery
SQL> recover database until time'2013-07-05'
Media recovery complete.
SQL> alterdatabase open resetlogs;
Databasealtered.
成功。
注:如果 alterdatabase open resetlogs;执行提示失败,那么 alter database opennoresetlogs;
