通过咨询是由于根据某厂商给出来的建议对对oracle的user$的系统默认用户update等操作

通过分析启动过程确认数据库在启动的时候访问lbacsys.lbac$pol表异常

PARSE ERROR #2:len=38 dep=1 uid=0 oct=3 lid=0 tim=37509085805630 err=942
select max(pol#) from lbacsys.lbac$pol

*** 2021-07-28 18:31:15.593
USER (ospid: 3512): terminating the instance due to error 12432

经过修改文件让数据库不在访问该表,数据库启动正常
