Using IBM HTTP Server and the WebSphere Plugin to load-balance workload across a non-federated WebSphere Application Server environment
This time around, I have a requirement to deploy IBM HTTP Server (IHS) and the WebSphere Plugin to route traffic to WebSphere Application Server (WAS). So far, so good. However, the difference is that, this time, I'm NOT leveraging the power of WAS Network Deployment ( WAS ND ). There are no clusters here. Equally, the two instances of WAS are completely self-contained. For my proof of concept, I've got a single set of WAS binaries ( I am using WAS 8.5.5.3 ) with a pair of standard profiles, AppSrv01 and AppSrv02. Similarly, I... [More]

Analyzing DataPower Latency Log
A very useful means of analyzing DataPower transaction latencies are the Latency log records (at information level), here an example: ... mpgw (coproc2xform) Latency: 0 17 0 17 20 14 11 20 22 20 22 513 0 20 17 17 [http://9.152.92.61:2223/] Paul Glezen created cool "dpShowLatency" tool, a Mozilla Firefox add-on for analyzing IBM DataPower latency log entries. The add-on is available at: http://pglezen.github.io/dpShowLatency/ This is how the above latency record displayed, after a nice animation finished: ... [More]

Changing the load balancing algorithm for your ODR-generated plugin-cfg.xml file
Users of WebSphere Virtual Enterprise (WVE) can utilize their On Demand Router 's (ODR's) to generate the plugin-cfg.xml file to be used with their WebSphere HTTP Plug-in module installed in an HTTP server such as IHS. But, did you know that you can set custom properties on the ODR to influence the settings used in the plugin-cfg.xml file? Here's how: To change the default plugin-cfg.xml values that the ODR uses simply navigate to Servers > On Demand Routers > on_demand_router > Java and Process Management > Process Definition...
