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

$ 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

$ nxsetup start Pool -l2

wait until Pool is started and run

$ nxsetup start MacroServer -l3

Additionally, one can create dummy devices by running sar_demo in

$ spock

Setting NeXus Servers

To set up NeXus Servers run

$ nxsetup set


$ nxsetup set NXSDataWriter
$ nxsetup set NXSConfigServer
$ nxsetup set NXSRecSelector

for specific servers.

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

$ nxsetup add-recorder-path /usr/lib/python2.7/dist-packages/sardananxsrecorder

where the path should point the sardananxsrecorder package.
