Scheduler jobs to refresh table data from SQL server

Question

Hi !
I am planning to have a scheudler job to refresh data from a SQL server database into Oracle. All I do is run several of the below statements. Each of these tables have less than 100 rows. So, it completes in under 20 seconds.
I am wondering if it is a good idea to run it as PL/SQL block as below. Please can someone comment ?
delete from B;                                                 
insert into A select * from AA@choumsq020;                                     
commit;
delete from B;                                            
insert into B select * from BB@choumsq020;                           
commit;
I am planning to run it as below
BEGIN
  DBMS_SCHEDULER.create_schedule (
    job_name        => 'TEST'
    job_type          => 'PLSQL_BLOCK'
    job_action      => 'begin 
               delete from B;                                                 
               insert into A select * from AA@choumsq020;                                     
               commit;
               delete from B;                                            
               insert into B select * from BB@choumsq020;                           
               commit;
               end; '   
    start_date      => SYSTIMESTAMP,
    repeat_interval => 'FREQ=MINUTELY, byminute=15',
    end_date        =>  NULL,
    comments        => 'Repeats every 15 mins, for ever.');
END;
/Am I doing anything wrong here ? I am yet to run it on the database
Thanks.

And use dbms_scheduler.create_job not dbms_scheduler.create_schedule.
Also leave start_date empty (that gets you systimestamp but at the timezone that
usually has a region instead of an absolute offset, like select dbms_scheduler.stime from dual
would report.
