[subexp-daq] problem when running two DAQs in parallel on one server

[Weber, Guenter Dr.]

Dear Håkan,


thank you very much for the reply. The explanation makes sense.


This is the EB command for the DAQ already running:


../drasi/bin/lwrocmerge \
    --label=EB \
    --port=7000 \
    --merge-mode=event \
    --server=trans \
    --server=stream,flush=1 \
    --buf=size=500Mi \
    --max-ev-size=1Mi \
    --eb-master=rio4l-2 \
    --drasi=rio4l-2 \
    --file-writer \
    "$@"


So, the only difference is the name "rio4l-2" in the old system vs. "rio4l-1" in the new system. And the port number "7000" vs. "8000". If "--server=trans" implicitly assumes a standard port, then this will be the same for both commands.


Is there somewhere an illustration/explanation how exactly LWROCMERGE and M_READ_MEB work together? This would help a lot.







Best greetings

Günter

Possily, your second EB has not started if the first is already running,
the

--server=trans  and  --server=stream,...

lines below use the default ports.  And if already in use by the first
process, it cannot start.  Try to add port=...
