Initial Setup == === 3.1 Starting the OML Server (if needed) === For this tutorial we have an OML server running on emmy9.casa.umass.edu, which collects the measurement data in an sqlite3 database and at the end of the experiment it pushes the data to IRODS. * Here is how you would have to start an OML server if you wanted to run this on a different machine (OML2.8 is required.) {{{ #!html DO NOT perform this task in the tutorial. }}} This is explained the [OML installation file]. {{{ $ /usr/bin/oml2-server -l 3003 --logfile=/var/log/oml2-server-2.9.log --user=oml2 --group=oml2 -H /usr/share/oml2-server/oml2-server-hook.sh }}} The latest version of OML offers the capability of executing a script after the measurement has finished. In OML terminology this is called a "hook". The hook script we use is attached at the bottom of this wiki page [http://groups.geni.net/geni/attachment/wiki/GIMI-GEC16-Tutorials/GIMI-GEC16-TutorialB/Orchestrate/oml2-server-hook.sh (oml2-server-hook.sh)]. {{{ #!/bin/bash # # Example event hook for the OML server, copying an Sqlite database elsewhere # when the last client has exited. # Copyright 2012-2013 National ICT Australia (NICTA), Australia # # Permission is hereby granted, free of charge, to any person obtaining a copy # of this software and associated documentation files (the "Software"), to deal # in the Software without restriction, including without limitation the rights # to use, copy, modify, merge, publish, distribute, sublicense, and/or sell # copies of the Software, and to permit persons to whom the Software is # furnished to do so, subject to the following conditions: # # The above copyright notice and this permission notice shall be included in # all copies or substantial portions of the Software. # # THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR # IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, # FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
