1.8 How to Inactivate the Optimizer Point
Important! Engineers Read This!
Shut the
Optimizer Off First
Use the Optimizer Bar – Select OFF [ENTER] Always shut Profit Optimizer
OFF from the Optimizer Bar before setting the point INACTIVE. Not doing so
has consequences for the current Profit Optimizer, and can have consequences for
other Profit Optimizers on the LCN.
Then Use the
Point Detail Pages
After shutting the optimizer down with the OFF button from any Profit Optimizer
display, call the Point Detail for the main optimizer point and INACTIVATE the
point.
To Restore
Control
To bring Profit Optimizer back on-line, reactivate the optimizer point then either
bring the Optimizer back on-line (WARM/ON).
Why You Need to
Do This
Profit Optimizer manages a 1.2MB workspace to form its optimization matrix.
Only one optimizer can have this space at a time. To control this space, Profit
Optimizer sets an internal flag
Where 1=occupied Ø=available
When an optimizer is running calculations in this space, the flag is set 1. Other
optimizers wanting to run a calculation have to wait for the space to open. On
exit, the flag is set Ø, and the workspace is freed.
Consequences on
Other Optimizers
Caution
If the optimizer you inactivate is occupying the workspace, and the optimizer is
not first shut OFF, the workspace flag is not reset. Other optimizers cannot get
into the workspace, so they cannot run their calculations, and cannot execute.
Execution overlaps begin, and optimization is eventually shed.
To restore optimization when this happens, shut down and restart the AM. If
changes have been made on AM, checkpoint AM before shutting down.
