一个新安装的12.2RAC环境，后台有日志报错如下：
2021-12-25T10:35:00.405492-05:00
Errors in file /oracle/app/oracle/diag/rdbms/bdcqx/bdcqx1/trace/bdcqx1_j000_16387.trc:
ORA-12012: error on auto execute of job "SYS"."ORA$AT_OS_OPT_SY_118"
ORA-20001: Statistics Advisor: Invalid task name for the current user
ORA-06512: at "SYS.DBMS_STATS", line 47207
ORA-06512: at "SYS.DBMS_STATS_ADVISOR", line 882
ORA-06512: at "SYS.DBMS_STATS_INTERNAL", line 20059
ORA-06512: at "SYS.DBMS_STATS_INTERNAL", line 22201
ORA-06512: at "SYS.DBMS_STATS", line 47197
这是12C的问题，参照MOS文档进行处理即可：
ORA-12012 Error on auto execute of job "SYS"."ORA$AT_OS_OPT_SY_<NN> in 12.2.0 Database version or higher release (like 18c) (Doc ID 2127675.1)
升级到12.2.0.1后数据库自动任务失败报错ORA-20001和ORA-00932 (Doc ID 2504954.1)
