wdisp/load_balancing_strategy is a SAP Parameter attribute which is used to control SAP Web Dispatcher: Set the load balancing strategy information. This is available within R/3 SAP systems depending on the version and release level.
Below is the standard documentation available and a few details of the attributes values .
You can use this parameter to set the load balancing strategy of the SAP
Web Dispatcher.
Following values are possible:
weighted_round_robin
Static, weighted round robin procedure; that is, the requests are
distributed in turn, in accordance with the server capacity value
(number of dialog processes or J2EE server nodes).
simple_weighted_round_robin
Also a weighted round robin, but with simplified scheduling: Each
server, S_i, with a weighting factor, w_i receives precisely w_i s
uccessive requests, before the next server, S_i+1 is assigned requests.
,,CAUTION
,,The value simple_weighted_round_robin only still exists for reasons of
compatibility. We recommend that ,,you use weighted_round_robin instead.
adaptive
To estimate the current load of a server (determine the "load factor"),
the actual response times to the ping requests sent periodically to each
server are used (instead of fixed predefined capacity values). The
smaller the response time (in milliseconds), the smaller the increment
of the current load factor for each request.
