Under WAM / Oracle 9i, jobs scheduled through the Job Manager ran in serial. In 10g, they appear
to run in parallel.
For example, assume we have two scheduled jobs, Job 1 and Job 2, set up to run 15 minutes apart
(Job 2 fifteen minutes after Job 1). Under 9i, if Job 1 took 20 minutes to run in some cases, Job
2 wouldn't start until Job 1 was completed. I.e. the second job would go into a wait-queue of
sorts. Under 10g, under the same conditions, Job 2 begins executing at 15 minutes after Job 1,
regardless of whether Job 1 completed or not.
Because some of our scheduled jobs are set up to be dependent of the results of earlier jobs, the
new behavior under 10g might present some support issues in the future.
