一 问题描述

Oracle告警日志有如下报错：

Errors in file /u01/app/oracle/diag/rdbms/yjt/yjt/trace/yjt_m000_3267.trc  (incident=223859):

手动生成快照也报一样的错误：

二 问题排查思路

点击以下网址查看ORA-600错误：https://support.oracle.com/epmos/faces/DocumentDisplay?id=153788.1&_adf.ctrl-state=yy192dbh2_172&_afrLoop=434945599224471

在Error Code First Argument处输入25027：

里面可以查看原因：

块在ASSM元数据L1位图块中标记为已格式化，但对于LOB段，该块儿未格式化。

三 解决办法

根据告警日志，查看当时的trace文件，查找要修复的表：

less /u01/app/oracle/diag/rdbms/yjt/yjt/incident/incdir_223859/yjt_m000_3267_i223859.trc

 这里打算通过以下方式修复：

create table sys.WRH$_SQL_PLAN_bak as select * from sys.WRH$_SQL_PLAN;

drop table sys.WRH$_SQL_PLAN;

#使用sys用户重命名表

rename  WRH$_SQL_PLAN_bak to WRH$_SQL_PLAN;

#手动给该表重建索引（因为create table as select并没有建索引）

alter table WRH$_SQL_PLAN ADD CONSTRAINT "WRH$_SQL_PLAN_PK" PRIMARY KEY ("DBID", "SQL_ID", "PLAN_HASH_VALUE"

, "ID");

重建后可以建快照了。

SQL> exec dbms_workload_repository.create_snapshot;

PL/SQL procedure successfully completed.
