　　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$
