ORA-01195: online backup of file 1 needs more recovery to be consistent

问题背景：
客户测试环境启动报错，协助排查处理

5 ORA-01195: online backup of file 1 needs more recovery to be consistent
6 ORA-01110: data file 1: '/data/oracle/oradata/ecology/system01.dbf'

 

原因分析：
2> 数据库恢复的时侯有一个问题：
DB恢复需要这个归档日志文件/data/oracle/flash_recovery_area/ECOLOGY/archivelog/2020_01_14/o1_mf_1_165_%u_.arc，
但是在备份中没有。

 1 SQL> recover database using backup controlfile until cancel;

18 文件 1 的联机备份需要更多的恢复来保持一致性 ORA-01110: 数据文件
19 1: '/data/oracle/oradata/ecology/system01.dbf'

解决过程：
准备使用隐含参数_allow_resetlogs_corruption强制启动DB：
提示：Oracle的隐含参数只应该在测试环境或者在Oracle Support的支持下使用。
设置此参数之后，在数据库Open过程中，Oracle会跳过某些一致性检查，从而使数据库可能跳过不一致状态。

 1 SQL> shutdown immediate;
 2 ORA-01109: database not open

23 ERROR at line 1:

以上强制启动后，产生Ora-600错误了，在预料之中

强制启动

 1 [oracle@oat ecology]$ sqlplus / as sysdba
 2 
 3 SQL*Plus: Release 11.2.0.1.0 Production on Tue Jan 14 13:21:18 2020
 4 Copyright (c) 1982, 2009, Oracle. All rights reserved.
 5 Connected to an idle instance.

 7 SQL> startup force;
 8 ORACLE instance started.

14 Redo Buffers    7360512 bytes
15 Database mounted.
16 Database opened.
17 SQL>

 

现在没问题了，把隐含参数改回默认的：

1 SQL> 
2 SQL> alter system set "_allow_resetlogs_corruption" =false scope=spfile;
4 System altered.

 

关闭测试启动

 1 SQL> shutdown immedaite;
 2 SP2-0717: illegal SHUTDOWN option
 3 SQL> shutdown immediate;
 4 Database closed.
 5 Database dismounted.
 6 ORACLE instance shut down.
 7 
 8 SQL> startup;
 9 ORACLE instance started.
