Performance and scalability?
The performance of ALE business processes depends on many factors (type of business process, number of messages, activities running on the distributed systems, hardware, and so on). To obtain detailed information about the performance a sizing procedure is required. The sizing procedure for SAP systems linked via ALE can be divided into two independent steps. In the first step only the activities within one system must be taken into account, in the second step the additional load created by the communication between the systems has to be determined. The total processing capacity (CPU, main memory, disk space and network bandwidth) needed for each individual SAP system can be calculated as the sum of the two steps of the sizing procedure. The reason for choosing this simplified sizing model is the following. The resource consumption of a business transaction depends only little on the fact whether the transaction was executed by an online user, a batch job or an interface program proces
