On my test database, Oracle scheduler seems a bit lethargic.

In my case, I am inserting data into 6 different tables ( million plus rows in each table ), these are done as insert into / select from via a stored procedure, I have a package with 6 procedures. In the package I create 6 jobs to do the insertion. At any given point only 4 jobs are running and they seem much slower then if I run these 6 procedures from a SQL Plus command line.

I created a new job class for these jobs and my job_queue_parameter is currently set to 160.

Is there something I can do to make these move faster via the scheduler ?

Thanks

A couple things to look at

- Check DBA_SCHEDULER_RESOURCES to see if any constraints have been placed on the concurrency of scheduler job executions
- How max'd out is your machine? The scheduler proactively looks at load via Resource Manager and will try to avoid over-stressing the machine
