Instructions to repeat last successful bluesky run

These commands in sequence in a terminal starting from an APS workstation with X11 running.

1. ssh -X bdp@terrier
2. become_bluesky
3. cd ~/qserver/
4. queue-monitor &
   1. ... the GUI starts in its own window
   2. click Connect in the Queue Server box on the Monitor Queue side tab
   3. click on the Edit and Control Queue side tab
   4. In the HISTORY table, find the last completed run and click it
   5. Above the table, click the Copy to Queue button
   6. New item should appear in the QUEUE table
   7. In the Queue section (near top of window), click Start button
   8. Watch things work... Console output will indicate when things are done.

5. qserver-console-monitor
   1. Leave this running in the terminal window. It shows any/all output from the bluesky queueserver.

When the steps to open the RunEngine appear to stall ...

Sometimes, the queueserver stalls while trying to open the RunEngine environment. Have not yet identified the root cause. This is the symptom of a stuck process. To resolve:

• login to bdp@terrier
• become_bluesky
• cd qserver
• export BDP_DEMO=M15
• ./qserver.sh restart

The export step is easily forgotten. This step configures the bluesky devices & plans for the current demo. Use M16 as the value for the BDP M16 milestone in September 2023.
