根据错误提示，涉及到一些trace文件，查看以下trace文件信息：
/u01/app/oracle/diag/rdbms/prtestdborcl/prtestdborcl/trace/prtestdborcl_m000_17750.trc
/u01/app/oracle/diag/rdbms/prtestdborcl/prtestdborcl/incident/incdir_193666/prtestdborcl_m000_17750_i193666.trc
从trace文件中查看涉及到系统表wrh$_sql_plan的插入操作，该表涉及AWR报告中的视图：
手工执行一些快照还原一情况，同时查看日志出现上面一样的报错：
SQL> exec dbms_workload_repository.create_snapshot;
BEGIN dbms_workload_repository.create_snapshot; END;

使用ORA-600/ORA-7445/ORA-700 Error Look-up Tool (Doc ID 153788.1)查找具体的报错信息
查看这对应的详细信息
查看对应的详细信息及堆栈信息：
从这里看看命中了Bug 18229901 - ORA-600 [qolhintpivaddsid:1], [25145], [25145 (Doc ID 18229901.8)
建议修改隐含参数：
alter system set "_b_tree_bitmap_plans"=false scope=both;
alter system set "_index_join_enabled"=false scope=both;
修改参数后，仍然报错，查看单个的补丁集：
根据自己的数据库版本查找对应的补丁集
根据readme进行升级补丁集：
进行升级补丁后，执行AWR快照没有问题：
SQL> exec dbms_workload_repository.create_snapshot;
PL/SQL procedure successfully completed.
