DCS is the only system that defines what is the set DCS is the only system that defines what is the set of commands may be launched by TDAQ and how of commands may be launched by TDAQ and how those commands will be executedthose commands will be executed

DCS developer has to implement command DCS developer has to implement command facilities in PVSS projectfacilities in PVSS project

First setup Online software by command line

source <TDAQ_INST_PATH>/setup.[c]shand set

PVSS_PATH = <Root directory of PVSS installation>

Then copy, perhaps with renaming (do not rename the files for the DDC testing purpose), the database template files into your working directory

cp $TDAQ_INST_PATH/share/data/ddc/ddc_playdaq.data.xml demo-partition.data.xml

cp $TDAQ_INST_PATH/share/data/ddc/ddc_test.data.xml ddc.data.xml
