sql - Using DBMS_SCHEDULER.CREATE_JOB within a procedure -

i trying create procedure perform updates on couple tables , schedule procedure run later revert them back. i'm running problem in using dbms_scheduler.create_job. code looks this:

create or replace procedure my_procedure(p_duns in varchar2, p_plus_four in varchar2)  *some variables*  begin  *do stuff*  p_job_action := 'begin run_other_procedure(' || p_vendor_id || ', ' || p_ccrid || ', ' || nvl(to_char(p_inactive_date),'null') || ',' || nvl(to_char(p_end_date),'null')  || '); end;';  dbms_scheduler.create_job(job_name        => 'deactive_vendor_'||to_char(p_ccrid),                       job_type        => 'plsql_block',                       job_action      => p_job_action,                       start_date      => sysdate+1,                       enabled         => true,                       comments        => 'calls plsql once');  end; 

i have verified beginning portion of procedure, when add in create_job i'm getting below error:

error starting @ line : 1 in command - execute my_procedure('140986105', null) error report - ora-27486: insufficient privileges ora-06512: @ "sys.dbms_isched", line 124 ora-06512: @ "sys.dbms_scheduler", line 271 ora-06512: @ "cgext.my_procedure", line 63 ora-06512: @ line 1 27486. 00000 -  "insufficient privileges" *cause:    attempt made perform scheduler operation without            required privileges. *action:   ask sufficiently privileged user perform requested            operation, or grant required privileges proper user(s). 

when pull out create_job , run have no problems.

any thoughts on this?
