This "How to" is assuming you are working in the DAQ.
How to Start the DAQ?
Please read the guide : Check the Guide for DAQ
The guide is kind of old, but the essential is there.
How to start the Database program ?
on the HELIOS commander, there is a button "Database" on top of the button "Stop"
How to deal with Buffer alert?
Usually, the buffer is low when there are too many triggers and cannot flush the data to the DAQ.
In many cases, the Database program will check the buffer level, if any VME buffer level is smaller than 300, the ACQ will be stooped for 30 sec and resume automatically.
How to Set Trigger?
anywhere>SetTrigger [VME] [DIG] [Plane]
There are two triggers, called X-Plane and Y-Plane, it has nothing todo with plane or beyond my imagination. .
when IOC switch off, what should I do ?
stop the run, wait for few minutes, start again.
if this keeps happening, reboot the DAQ.
