The overall performance tuning that is done by the system can play a significant role during error recovery scenarios. For example, you might need to change the machine pool if it is too small because it can cause excessive error recovery times.
The automatic performance adjustment function of the system is set to 2 when the system is shipped. The system can automatically adjust the performance of the system based on this value. Automatic adjustment might be a desirable feature, particularly when unexpected loads hit the system. Automatic adjustment can help the system perform better through these peak loads.
You should consider dividing communications users (whether they are remote workstation or APPC communication users) into multiple subsystems. If communications fails, all users who are in a single subsystem might be affected as a result of the communications recovery that is performed on their systems. For more information, see:
