Setting environment

Setting Saradna ^^^^^^^^^^^^^^^ If sardana is not yet set up run

  $ Pool

• enter a new instance name
• create the new instance

Then wait a while until Pool is started and in a new terminal run

.. code-block:: console

  $ MacroServer

• enter a new instance name
• create the new instance
• connect pool

Next, run Astor and change start-up levels: for Pool to 2, for MacroServer to 3 and restart servers.

Alternatively, terminate Pool and MacroServer in the terminals and run

.. code-block:: console

      $ nxsetup -s Pool -l2

wait until Pool is started and run

.. code-block:: console

      $ nxsetup -s MacroServer -l3

Additionally, one can create dummy devices by running sar_demo in

If the RecoderPath property of MacroServer is not set one can do it by

.. code-block:: console

  $ nxsetup -a /usr/lib/python2.7/dist-packages/sardananxsrecorder

where the path should point the sardananxsrecorder package.
