Setting environment
-------------------

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

.. code-block:: console

$ 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

.. code-block:: console

$ spock

Setting NeXus Servers
^^^^^^^^^^^^^^^^^^^^^

To set up NeXus Servers run

.. code-block:: console

$ nxsetup -x

or

.. code-block:: console

$ nxsetup -x NXSDataWriter
$ nxsetup -x NXSConfigServer
$ nxsetup -x NXSRecSelector

for specific servers.

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.
