Cheers, Roman.

@lietava Looks fine, but when are calling these functions? How this is correlated with the ECS SOR/EOR?

I understand this, the question is when exactly this happens wrt the actual data taking. We should be sure that by the time data arrives to the EPN the CCDB object is ready.

@shahor02 :
Global run for CTP starts in two steps Load and Start.
At Start CTP starts to send HB and Physics triggres.
IN the current version it is written at Start. It is possible to move it to Load. There are usually at least seconds between Load and Start.

Earlier we do this, better it is.

ok, then, please, hold this request until I tell you or change it to draft.

@shahor02 , please, pull
