SAP Web Dispatcher or ICM of kernel version 7.40 or higher required.
This note describes how to tune SAP Web Dispatcher or ICM with kernel release 7.40 or higher for handling a given number of concurrent connections. Supporting a large number of concurrent connections requires memory resources, so it makes sense to configure this number according to needs. However, the impact of this configuration on memory consumption is relatively small (see below), so in general it is better to oversize and waste a bit of memory than to undersize and annoy users by rejecting their connection requests.
