Load Balancing

[Imene1]

To ensurea good balancing two application servers are created and configured with WEBDISPATCHER, in the totally we have 3 application servers ( 1 main server and 2 secondery servers) but the load blancing problem still persists, the requests go directly to the main application server and saturates it.

my question is the following how to resolve the balancing problem and distribute the requests fairly between the 3 application servers?

NB: Version SAP ECC6 EHP7

thanks in advance

Firstly, the WEBDISPATCHER is only used for the HTTP/HTTP connections. For RFC or SAP GUI ones, the Message Server natively handles them (if the LOGON SERVERS groups are configured correctly, TCODE SMLG).

By default, SAP WD uses a Weighted Round Robin strategy by default. But if you see that's not working, you can change it to Load Balancing Using Server Response Times (namely if the servers are very different in performance). Please check this link:
