It sounds like you are trying to duplicate what the oracle job scheduler already does for free. If a tool already exists, reinventing it makes for problems down the road.

You will want to consider a daemon running in the background as the oracle user. The process checks the table, say once a minute to look for jobs to start.

But. If a data problem caused the job to fail in the first place, it will continue failing.
Unless a human intervenes to fix the issue.
So, you will need a table with date stamped status flags to indicate:

Code:

Successful completion - completed all jobs in one stream
Forced completion - mark this job stream as complete even though it failed
Failure pending restart - Got fixed please restart, Mr. job controller <- this one does what you asked
Failure - bombed, needs user attention - has sent an email
New job -  added every day/hour/week(?) by cron job to allow daily processing

Status should be indexed by some kind of unique job identifier, so that all New jobs when complete relates to one of the completion status steps. This is how the controller knows what to do. Plus, you can see repeated failures for the same job stream.

You need to add in the steps to the status 'Please restart me', so the daemon knows exactly what to do. Same is true for job properties like user/password/parameters

You also need something to notify users/support when a job bombs.

If you do not know enough to write a daemon, consider a set of shell scripts that are under the control of one master script which runs from crontab every minute or so. You can use the at or batch facility to do the submission.

NAME

       Gtk2::ListItem - wrapper for GtkListItem

DESCRIPTION

       Gtk2::ListItem is the widget used for each item in a Gtk2::List.  Gtk2::List and Gtk2::ListItem are deprecated; use Gtk2::TreeView and a
       Gtk2::ListStore instead.

       Gtk2::ListItem is included in Gtk2-Perl only because Gtk2::Combo contains a Gtk2::List, and Gtk2::Combo's replacement, Gtk2::ComboBox,
       didn't appear in gtk+ until 2.4.0.
