Case 3: Skip if Busy can be used to omit map instances from starting
The Skip if Busy Option can be used to omit map instances from starting when another instance is in process.
In this case, it might not matter what options you select for work files and log files because map instances always run sequentially.
Note: If you want multiple instances of the same
map to be able to run at the same time, be sure to select unique work
files and unique log file run options. These options create different
work files and log files for each map instance so that one map instance
will not interfere with another. If you do not select these options,
the Launcher will
keep the second instance in a pending state until the first instance
has completed.
