GT 3.9.4 WS MDS Index Service: System Administrator's Guide

Introduction

The Index Service collects information from services and resources (member services) in a virtual organisation, and publishes that information in a centrally accessible place.

Building and Installing

The Index Service is built and installed by default along with the rest of the Globus Toolkit. [TODO: link to toolkit install guide]

Configuring

Information on configuration settings and environment variables can be found in the public interface guide.

For a basic installation, the index service itself does not need any configuration changes from default.

In order for member services to appear in the index, they must be registered using the mds-servicegroup-add tool. This tool should be run as a daemon to maintain registrations. Depending on administration preference, it may be run on the same host as the index, on the same host as a member resource, or on any other host(s).

The aggregation source used to collect data can be changed from default, as detailed in the Public Interface Guide

Deploying

The Index service is deployed into the Globus container by default during the standard toolkit installation.

Testing

The entire content of the default index service in a deployment can be seen by executing the following command, which will dump the entire RP set of the service:

wsrf-query -a -z none -s https://127.0.0.1:8443/wsrf/services/DefaultIndexService /
