ORA-00604: 递归 SQL 级别 1 出现错误

ORA-00942: 表或视图不存在

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)
