If you intend to run more than one copy of your application at the same time, you must ensure that you have sufficient Micro Focus Server licenses to cover the number of concurrent users. During an exceptional period, for example, at year end, you might need to run more concurrent copies of your application than usual. You need to purchase sufficient Micro Focus Server licenses to cover this situation. However, to help you cope with unexpected fluctuations in use, and to give you time to purchase additional Micro Focus Server licenses, AppTrack has a built-in limited overdraft facility. This takes into account all the Model 2 licenses installed on the UNIX machine.
AppTrack monitors the usage of license units and when it detects usage in excess of the licensed capacity, updates are made to the file overdraft.log, which is in the directory /var/mfaslmf.
You are allowed to exceed the number of Micro Focus Server licenses you are authorized for (your "licensed capacity") by up to 10%.
You are also allowed to exceed the licensed capacity by more than 10% for up to 10 days. Each day that you exceed your licensed capacity by more than 10% is known as an overdraft day. When an overdraft day occurs it is logged in the overdraft file, and the number of overdraft days remaining is reduced by 1. An email is sent to the systems administrator informing them that an overdraft has occurred, and how many overdraft days they have left. On the eleventh overdraft day, any application requesting an overdraft will fail. You must apply to Micro Focus to increase your licensed capacity, then install the extra licenses. Only when you have the extra capacity installed can the overdraft mechanism be reset.
After 10 consecutive days have elapsed during which no overdrafts occur, the overdraft accumulated so far is reset to zero.
