    1313=== Using Result Service ===
    14 The console has a result service running on port 5054. On the grid console the service can be accessed from the URL: grid.orbit-lab.org:5054/result. From the console the user can use a non-interactve network downloader (ie. wget) to retrieve results. A web browser (ie. Chrome) can also be used however tunneling to the console will need to be set up.

     14The console has a Result Service running on port 5054. For example on the grid console the service can be accessed at the URL: ''grid.orbit-lab.org:5054/result''. From the console the user can use a non-interactve network downloader (ie. wget) to retrieve results. A web browser (ie. Chrome) on a different machine can also be used however tunneling through the console is required.

     16To view all the services provided use command:

     18nilanjan@console.grid:~$ wget -qO- grid.orbit-lab.org:5054/result | xml_pp
     19}}}
     20
     21The services will be displayed in XML format with a brief description between the ''info'' tags and required argument(s).

     74Listed below are a few example uses of the services for a given Experiment ID (''default_slice-2014-10-20t10.59.11.720-04.00''). Assume all commands are case-sensitive.
     75 1) Dump the contents of the database in sqlite3 text format:
     76{{{
     77nilanjan@console.grid:~$ wget -qO- grid.orbit-lab.org:5054/result/dumpDatabase?expID=default_slice-2014-10-20t10.59.11.720-04.00
     78}}}
     79
     80 2) Print all tables in the contained in the database in XML format:
     81{{{

     97 3) Run a query on a database table and display contents in XML format:
