IceStorm example - configuration

[Bruce]

I am working through the publisher/subscriber example in chapter 25, and I am having a bit of trouble working out exactly what goes in the config_service and config files to get this example working. Can you give me an example of the bare minimum config for this example?

Hi Bruce!

Naturally you can configure your applications however you see fit.

In the example demo/IceStorm/clock, we use the file config_service for IceBox, and the file config for IceStorm, the publisher and the subscriber. If you look closely at config_service, you'll notice that the IceStorm service is configured with the argument --Ice.Config=config, which causes it to load the properties in config.

To be more specific, IceBox requires the following properties in order to load IceStorm:

IceBox.ServiceManager.Endpoints=<sm-endpoints>
IceBox.Service.IceStorm=IceStormService,12:create
IceBox.DBEnvName.IceStorm=<dbdir>

IceStorm requires the following properties:

IceStorm.TopicManager.Endpoints=<icestorm-endpoints>
IceStorm.Publish.Endpoints=default

Publishers and subscribers need a proxy for the TopicManager. In this example they use the following property:

IceStorm.TopicManager.Proxy=IceStorm/TopicManager:<icestorm-endpoints>

Hope that helps,
