有一个朋友说他们想把12c的库还原到19c版本中然后进行升级测试,结果在打开库的过程中发现几个错误,让我给帮忙分析下
resetlogs 报ORA-00392 ORA-00312

SQL> alter database open resetlogs upgrade;
alter database open resetlogs upgrade
*
ERROR at line 1:
ORA-00392: log 7 of thread 1 is being cleared, operation not allowed
ORA-00312: online log 7 thread 1: '/DBS1/data/NDBS/onlinelog/redo07_m1.log '
ORA-00312: online log 7 thread 1: '/DBS1/arch/NDBS/onlinelog/redo07_m2.log '

这个错误一般是由于redo状态不对,比如标记为了CLEARING_CURRENT,处理操作

SQL> select group#,status from v$log;

          GROUP# STATUS
---------------- ----------------
               1 CLEARING
               2 CLEARING
               3 CLEARING
               4 CLEARING
              10 CLEARING
               6 CLEARING
               7 CLEARING_CURRENT
               8 CLEARING
               9 CLEARING
               5 CLEARING

10 rows selected.


SQL> alter database clear logfile group 7;

Database altered.

SQL> select group#,status from v$log;

          GROUP# STATUS
---------------- ----------------
               1 CLEARING
               2 CLEARING
               3 CLEARING
               4 CLEARING
              10 CLEARING
               6 CLEARING
               7 CURRENT
               8 CLEARING
               9 CLEARING
               5 CLEARING

10 rows selected.

再次reseltogs报ORA-600 ksvworkmsgalloc: bad reaper错误

SQL> alter database open resetlogs upgrade;
alter database open resetlogs upgrade
*
ERROR at line 1:
ORA-00600: internal error code, arguments: [ksvworkmsgalloc: bad reaper], [0x080010003], [], [], []

这个错误通过查询MOS 发现Open Resetlogs Fail with ORA-00600[ksvworkmsgalloc: bad reaper] (Doc ID 2728106.1)文章中描述,由于non-ASM to ASM环境redo文件在clear的时候触发该问题
