11.2.0.3 下嘗試使用11g health monitor新特性時出現了ORA-00604、ORA-01427， 查詢MOS發現 (Bug 12385172: ORA-01427 WHEN EXECUTING DBMS_HM.RUN_CHECK)，當 DB中存在case when then的function index時會觸發該BUG:

SQL> select * from v$version;

BEGIN dbms_hm.run_check('Dictionary Integrity Check','check-2'); END;

ERROR at line 1:

ORA-00604: error occurred at recursive SQL level 1

ORA-01427: single-row subquery returns more than one row

ORA-06512: at "SYS.DBMS_HM", line 191

ORA-06512: at line 1

可以通過以下腳本找出 DB中case when then類型的函數索引：

-- Determine DDL statements (note: this will take a while to return results!)

set long 100000

exec dbms_metadata.set_transform_param(dbms_metadata.session_transform,'PRETTY',true);

exec dbms_metadata.set_transform_param(dbms_metadata.session_transform,'TABLESPACE',false);

exec dbms_metadata.set_transform_param(dbms_metadata.session_transform,'SEGMENT_ATTRIBUTES',false);

exec dbms_metadata.set_transform_param(dbms_metadata.session_transform,'STORAGE',false);

-- Checking the DDL statement

col DDL form a100 word_wrapped

select dbms_metadata.get_ddl(RTRIM(UPPER(object_type)),
