The SAP Web Dispatcher

The SAP Web Dispatcher is required to connect the internet and the SAP system. Read this topic for installation information.

TheSAP Web Dispatcher receives requests from the internet (http/https) and forwards the requests to an ABAP server or Java™ application server. The incoming requests are distributed among the application servers according to their capacity weighting (the amount of dialog work processes for application server ABAP and the amount of server processes for application server Java).

On z/OS® UNIX, you can install the SAP Web Dispatcher exclusively as a stand-alone engine, with its own SAP system identifier (SID). This way it can connect to multiple SAP systems. An own SID ensures that the SAP kernel level of the SAP Web Dispatcher remains independent of the kernel levels of the other SAP systems to which it connects.
