Get DDL of DBMS Scheduler packages job in Oracle

Create a package before they get the DDL:

SQL> BEGIN
dbms_scheduler.create_job(
job_name => 'Full_Backup'
,job_type => 'backup_script'
,job_action => 'C:\script\rmanbackup.rman'
---,credential_name => 'Windowuser'
,start_date => SYSDATE +1/24/59
,repeat_interval => 'FREQ=DAILY; BYHOUR=9; BYMINUTE=38;'
,enabled => TRUE
,comments => 'Full DB BACKUP'
);
END;
/
PL/SQL procedure successfully completed.


-- We update the Password later
BEGIN
DBMS_SCHEDULER.SET_ATTRIBUTE (
name => 'Full_Backup',
attribute => 'credential_name',
value => 'Windowuser');
END;
/


Getting the DDL of the above Scheduler Package from Oracle database:
1. Get the owner detail

col owner for a8
col job_action for a30
col job_name for a15
col credential_name for a20
select owner,job_name,job_action,credential_name from dba_scheduler_jobs where job_name like 'FULL%';

OWNER    JOB_NAME        JOB_ACTION                     CREDENTIAL_NAME
-------- --------------- ------------------------------ --------------------
SCOTT    FULL_BACKUP     C:\script\rmanbackup.rman      WINDOWUSER

2.Fetch the DDL of the DBMS Scheduler package with DBMS Metadata package

SELECT DBMS_METADATA.get_ddl('PROCOBJ','FULL_BACKUP', 'SCOTT') AS JOB_DDL FROM dual;
