  • Oracle备份恢复之断电导致控制文件和日志文件损坏修复

    Oracle数据库遭遇断电遭遇ora-00214、ora-00314、ora-00312错误恢复案例一枚

    1、数据库在17日21:19启动开始报错ora-214错误:

    Tue Jan 17 21:19:10 2017

    alter database mount exclusive

    Tue Jan 17 21:19:13 2017

    ORA-214 signalled during: alter database mount exclusive...

    Dump file d:oracleproduct10.2.0adminorcldumpalert_orcl.log

    2、从控制文件看目前controlfile文件信息如下:

    control_files            = D:ORACLEPRODUCT10.2.0ORADATAORCLCONTROL01.CTL, D:ORACLEPRODUCT10.2.0ORADATAORCLCONTROL02.CTL, D:ORACLEPRODUCT10.2.0ORADATAORCLCONTROL03.CTL

    3、从sqlplus界面看到CONTROL01.CTL的版本号低于CONTROL02.CTL版本号,根据规则、保留高版本CONTROL文件原则尝试重新启动数据库:

    修改参数文件中控制文件信息如下:

    control_files            = D:ORACLEPRODUCT10.2.0ORADATAORCLCONTROL02.CTL, D:ORACLEPRODUCT10.2.0ORADATAORCLCONTROL03.CTL

    尝试重新启动数据库,成功进入mount状态。

    Fri Apr 14 10:28:33 2017

    ALTER DATABASE   MOUNT

    MMNL started with pid=12, OS id=4396

    Fri Apr 14 10:28:37 2017

    Database mounted in Exclusive Mode

    Completed: ALTER DATABASE   MOUNT

    4、继续open数据库,发现报错如下:

    Fri Apr 14 10:28:37 2017

    ALTER DATABASE OPEN

    Fri Apr 14 10:28:38 2017

    Errors in file d:oracleproduct10.2.0adminorcldumporcl_lgwr_5244.trc:

    ORA-00312: online log 1 thread 1: 'D:ORACLEPRODUCT10.2.0ORADATAORCLREDO01.LOG'

    Fri Apr 14 10:28:38 2017

    ORA-00312: online log 1 thread 1: 'D:ORACLEPRODUCT10.2.0ORADATAORCLREDO01.LOG'

    警告日志报错D:ORACLEPRODUCT10.2.0ORADATAORCLREDO01.LOG日志文件损坏。

    5、清空日志组1,成功open数据库:

    Fri Apr 14 10:48:48 2017

    alter database clear logfile group 1

    Fri Apr 14 10:48:48 2017
