Betekenis van Verticaal en Horizontaal Schalen



Agenda



● IBM HTTP Server


● WAS Terminology


● Praktijkcase

● Vragen ?



Lotus Connections topology



EDGE Component

● IBM HTTP Server (IHS) --> Verticaal schalen

Meer threads voor parallelle afhandeling

ThreadsPerChild

ThreadLimit

Meerdere deamon processen

● IHS --> Horizontaal schalen

dmv LoadBalancer

EDGE Component



Agenda



● IBM HTTP Server


● WAS Terminology


● Praktijkcase

● Vragen ?



IBM HTTP Server

● IHS = Apache Webserver

● IHS 6.1.0.23 gebaseerd op Apache v2.0.63

IHS 6.1.0.13 is gebaseerd op apache 2.0.61

● IBM modules ter ondersteuning van WAS

Belangrijkste module is de WAS Plugin

mod_was_ap20_http.dll

Ook ondersteuning voor Apache 2.2
