Using ORBIT Web based services

ORBIT support services have web based XML interfaces. They all use the same framework and, therefore, have like syntax. The services are accessed using either of the following schemes:

http://<serviceGroup name>:5012/<serviceGroup name>/<service name>?<1st arg>=<arg_1_value>&<2nd_arg>=<arg_2_value>

For instance, to turn on node1-1 using the CMC (from the console of one of the sandboxes or the grid), you would issue the following:

wget -O - "http://cmc:5012/cmc/nodeSetOn?nodes=[1,1]"

The services are location aware and will manipulate the resources for that specific location. For instance, querying the CMC to turn on node1-1 from the console on sb1 will turn on node1-1 on sb1 and not any other resource. Also, it is impossible for users in one location to issue commands for another. For example, it is impossible to turn on nodes on the grid from the console of sb1. One of the obvious advantages of this is experiment scripts/applications need only mention the service name to be portable.

Below is a list of available services and their corresponding arguments.
