Runs the specified checker with the given arguments. The run's report will be maintained persistently in database.
dbms_hm.run_check(check_name IN VARCHAR2,
checkname    IN VARCHAR2,
run_name     IN VARCHAR2 := NULL,
timeout      IN NUMBER   := NULL,
input_params IN VARCHAR2 := NULL);

Checkers

DB Structure Integrity Check
Data Block Integrity Check
Dictionary Integrity Check
Redo Integrity Check
Transaction Integrity Check
Undo Segment Integrity Check

Check names and their parameters can be accessed from the gv$hm_check and gv$gm_check_param.
Users can run all checks which are not internal in nature for example:

SELECT name
FROM gv$hm_check
WHERE internal_check = 'N';


which retrieves the list of checks that can be run manually by users.

SELECT name FROM gv$hm_check;

SELECT name FROM gv$hm_check
WHERE internal_check = 'N';

SELECT run_id FROM gv$hm_run;

exec dbms_hm.run_check('Dictionary Integrity Check', 'Run 2', 60);

SELECT run_id, name, check_name, run_mode, status, src_incident, num_incident, error_number
FROM gv$hm_run;

set linesize 121
col description format a40
col damage_description format a40

SELECT finding_id, status, type, description, damage_description
FROM gv$hm_finding
WHERE run_id = 221;

col name format a10
col repair_script format a60

SELECT name, type, rank, status, repair_script
FROM
gv_$hm_recommendation
WHERE run_id = 21
AND fdg_id = 22;
 
RUN_DDE_ACTION

Runs a DDE (user) action for HM checks ... Appears to be for internal usage only
dbms_hm.run_dde_action(
incident_id    IN NUMBER,
directory_name IN VARCHAR2,
check_name     IN VARCHAR2,
run_name       IN VARCHAR2,
timeout        IN NUMBER,
params         IN VARCHAR2)
RETURN BOOLEAN;
SELECT num_incident, check_name, name, timeout
FROM gv$hm_run;
