通过这里可以知道数据库在启动的过程中由于无法访问access$表从而出现ORA-00942错误,又是由于该sql是数据库内部调用因为出现ORA-00604错误.
出现该错误的原因是由于:BUG:12733463 – ORA-704, ORA-604 AND ORA-942 ON TABLE ACCESS$ DURING STARTUP
官方提供方法
1. Shutdown (abort) the instance and clean up any OS structures used by the instance.
Eg: Ensure there is no shared memory, semaphores etc.. left lying around
2. Retry the startup.
3. If the error persists try and recover the database or recover from a backup.
惜分飞处理方法
startup upgrade
create table access$
( d_obj# number not null,
order# number not null,
columns raw(126),
types number not null)
storage (initial 10k next 100k maxextents unlimited pctincrease 0)
/
create index i_access1 on
access$(d_obj#, order#)
storage (initial 10k next 100k maxextents unlimited pctincrease 0)
