Parameter
wdisp/load_balancing_strategy
Short text
SAP Web Dispatcher: Set the load balancing strategy.
Parameter Description
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 successive 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.
