I am trying to create a Scheduler Window that opens when another closes. The Window I have a dependency on is not mine to control and it's scheduler could change. I've read that Fine Manual (Scheduler Admin guide and DMBS_SCHEDULER), but it doesn't look like this is possible. The only solutions that I could think off are ugly:

1) have a check job that runs in my window to check the schedule of the window I need to run after. If that window schedule has changed, I alter the schedule of mine to follow. The problem is that this is always reactive (as well as a hack).

2) create a dummy job in the window I have a dependency on that is set to stop when the window closes and use events from that to trigger my window somehow (TBD). An even worse hack as I don't want to create jobs in that window.

Ideally I want to be able to set a windows schedule as following another window or have the window somehow raise events. Any version past 12.2 in case I've missed something in a later version.

Any ideas?

Many thanks
