I have a procedure that selects over 8 million records from one table into another. The select can be sorted by subscriber id which is the key on the source table.

This job runs way too long so I'm looking for a way to run the procedure in concurrent jobs.

I'm thinking of using the dbms_jobs package tot kick off maybe 5 - 10 jobs sumiltaniously, but I'm not sure how to handle the process so that it executes the subscriber id's in sequience without processing any of them twice.

Any help will be much appreciated !!

You might not even need to re-event the wheel, Oracle already has a built-in support for parallel execution of queries.

Example :

alter session enable parallel dml;
insert /*+ parallel (emp_big,4,1) */
  into emp_big select * from emp;
alter session disable parallel dml;

For more information have a look here :
