Quick Start Guide

The DRO bridges disjoint topic resolution domains by forwarding multicast and/or unicast topic resolution traffic. Before installing and starting a DRO daemon (tnwgd) clear objectives and proper planning are very important. Approach this planning with the consideration that a DRO condenses your network into a single process. You must be clear about the traffic you expect to forward through a DRO. The following highlights some other specifics.
Know your Topic Resolution Domains. See Topic Resolution Domains.
Consider the size and quality of network paths into and out of your DROs. For example, DROs cannot efficiently forward messages from a 1GB path to a 100MB path.
The daemon, umestored, provides persistent store services. To start umestored, perform the following steps:
Create the cache and state directories.
$ mkdir umestored-cache ; mkdir umestored-state
Create a simple umestored XML configuration file or use a sample configuration, ume-example-config.xml. For full details on Persistence, see Ultra Messaging Guide for Persistence.
$ umestored config.xml
