Managing several.
WHAT TO AVOID
Scheduling everything at the same time.
Several heavy jobs running simultaneously spikes resource use.
HOW TO STAGGER THEM
Offset the minutes. One at five past, one at twenty past, one at thirty-five past.
DOCUMENTING THEM
What each does, why it exists, what depends on it.
With several, you will not remember.
WHAT TO REVIEW
Jobs for applications you removed Jobs duplicated during a migration Jobs running far more often than needed
THE DUPLICATE PROBLEM
After a migration, jobs are frequently recreated without the old ones being removed.
Check the list.
WHAT SIGNS TO WATCH FOR
Resource usage spiking at regular intervals Disk filling with output The same task running twice
FOR MANY JOBS
Consider whether one job calling a script that decides what to run is simpler.
That is what application schedulers do.
