接手客户故障数据库报错为:ORA-16433

SQL> recover datafile 1;
ORA-00283: recovery session canceled due to errors
ORA-16433: The database or pluggable database must be opened in read/write mode.

这个错误一般是由于之前resetlogs未能正常打开库导致,通过rectl之后,尝试重新打开库,报错为:ORA-600 kcbzib_kcrsds_1

SQL> ALTER DATABASE OPEN;

这个错误一般是scn问题,对于之前版本直接使用隐含参数,event,oradebug进行调整scn即可,但是在12.2版本之后无法使用这些方法修改,处理起来相对麻烦一些，参考以前处理的相关文章:

12C数据库报ORA-600 kcbzib_kcrsds_1故障处理

发表于 2020 年 11 月 30 日 由 惜分飞

有朋友由于主机断电,导致数据库无法启动,需要我们提供恢复支持.通过Oracle数据库异常恢复检查脚本(Oracle Database Recovery Check)检查分析,发现存放在一个磁盘的数据文件scn过小,数据库无法正常open,需要历史redo(已经被覆盖,而且数据库未归档).
20201130202509
20201130202545

对于这种情况,选择强制拉库,然后数据库报ORA-600 kcbzib_kcrsds_1错误
20201130203023
20201130203204
对于此类故障参考以前处理过类似案例:ORA-600 kcbzib_kcrsds_1报错,对数据库scn进行修改(这类错误可以通过PATCH SCN工具快速解决),数据库顺利open

模拟19c数据库redo异常恢复

发表于 2020 年 11 月 16 日 由 惜分飞

对于19c在pdb情况下三种常见故障进行了模拟测试:
模拟19c数据库redo异常恢复
模拟19c数据库pdb undo异常恢复
模拟19c数据库root pdb undo异常恢复
模拟oracle 19c数据库redo丢失的恢复操作,模拟数据库有事务,在没有提交的情况下redo丢失故障

另外一个会话kill数据库并且删除redo

[root@localhost ~]# ps -ef|grep pmon
oracle    38500      1  0 16:08 ?        00:00:00 ora_pmon_ora19c

[root@localhost ~]# kill -9 38500
[root@localhost ~]# ps -ef|grep pmon
root      39042  39009  0 16:11 pts/2    00:00:00 grep --color=auto pmon
[root@localhost ~]# ls -l /u01/app/oracle/oradata/ORA19C/redo*.log
ls: cannot access /u01/app/oracle/oradata/ORA19C/redo*.log: No such file or directory

启动数据库报错ORA-00313 ORA-00312 ORA-27037

因为redo全部丢失只能尝试强制拉库

数据库报ORA-600 kcbzib_kcrsds_1错误是由于在强制拉库过程中文件异常导致,通过对异常文件进行处理数据库open成功

SQL> recover database;
Media recovery complete.
SQL> alter database open;

Database altered.

SQL> 

SQL> alter session set container=pdb;

Session altered.

SQL> alter database open;

SQL> show pdbs;

    CON_ID CON_NAME                       OPEN MODE  RESTRICTED
---------- ------------------------------ ---------- ----------
         2 PDB$SEED                       READ ONLY  NO
         3 PDB                            READ WRITE NO

这个是模拟redo丢失或者损坏故障,在实际的生产故障中可能要比这个复杂很多.
