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,数据库顺利open

记录一次pdb恢复过程中遇到的大量bug

12C版本使用pdb的Oracle数据库,由于在创建index的过程中强制终止,导致业务大量阻塞,然后重启数据库几次之后直接crash,最后直接无法open成功,报ORA-00600 6856

这个错误比较明显是由于ORA-600 6856错误导致数据库在启动的时候无法进行实例恢复,出现这个错误原因是由于客户创建index的过程中强制终止引起Bug 17437634 – ORA-1578 or ORA-600 [6856] transient in-memory corruption on TEMP segment during transaction recovery / ROLLBACK (eg: after Ctrl-C) – superseded (Doc ID 17437634.8),屏蔽该文件实例恢复,cdb启动成功,但是pdb无法正常open

这个错误比较明显是由于ORA-600 kcffo_online_pdb_check:fno_system,数据库未正常检测到pdb的system文件导致该问题,通过对pdb的system文件进行操作,让数据库识别到该文件,然后继续open库

SQL> alter database open;
alter database open

ERROR at line 1:
ORA-00603: ORACLE server session terminated by fatal error
ORA-01092: ORACLE instance terminated. Disconnection forced

Process ID: 224476
Session ID: 13311 Serial number: 59525

该错误是由于数据库在恢复的过程中推了scn,触发了oracle 某种bug导致该问题,通过一些操作之后,数据库可以open,尝试temp表空间增加临时数据文件报ORA-00600 [kcffo_add_tmpf-1] 错误(Bug 29379978 – ORA-00600 [kcffo_add_tmpf-1] when trying to add temp file (Doc ID 29379978.8)).由于该文件无法加入,数据库无法导出
20201115115951


最后没有办法换了思路直接bbed修改文件头,open cdb库,然后open pdb,顺利导出数据.这次的恢复中,深刻的体验到pdb在open过程中的各种bug,实在比较厌烦.
