有客户联系我,说数据库故障经过他们一系列恢复之后,现在open库报ORA-01113 ORA-01110错误,咨询我Oracle Recovery Tools恢复工具是否可以解决该问题

alert日志报错

Sat Dec 16 09:10:45 2023
alter database open
Errors in file f:\app\administrator\diag\rdbms\orcl\orcl\trace\orcl_ora_8948.trc:

ORA-01110: 数据文件 1: 'F:\APP\ADMINISTRATOR\ORADATA\ORCL\SYSTEM01.DBF'
ORA-1113 signalled during: alter database open...

其实这个错误不是这个库不能打开的本质,一般遇到这种错误的客户,都是强制拉过库,在拉库的过程中失败,才是导致库不能open的本质原因,比如通过查看相关日志发现拉库的时候报ORA-01555 ORA-00704错

比如还有客户咨询也是ORA-01113 ORA-01110错误,希望通过Oracle Recovery Tools工具来解决该问题,通过咨询客户确认他们其实是在前期恢复中报ORA-600 2662错误

对于一般通过强制拉库启动过程中报ORA-600错误,后面恢复中报ORA-01113 ORA-01110错误无法正常open的库,一般不用Oracle Recovery Tools工具来解决,通过一些恢复技巧就可以解决该问题.如果无法自行解决,可以联系我们进行技术支持,最大限度抢救和数据,减少损失
