The complete documentation for the DAQ - DCS Communication package may be found at the ATLAS DCS site http://atlas.web.cern.ch/Atlas/GROUPS/DAQTRIG/DCS/DDC/ddc.html
The internal changes of the package w.r.t DDC v. 5.1 of the previous release:
1. New internal interfaces to TDAQ packages: DAL, IS, MRS and RunControl. They follow up moving those packages to use ERS for reporting errors.
2. The elements of the schema of the DDC configuration database, which are not necessary for the DIM based DDC package, are dropped. They are:
- connectDelay and connectRetries attributes of classes DdcCtApplication, DdcDtApplication and DdcMtApplication;
- PollInterval of the class PvssDatapoint;
- PvssEventPort and PvssDataPort of the class PvssWorkstation.
No changes of the DDC functionality or interface. Previously used DDC configuration databases may be used without any changes, though one may see the warnings in the log file concerning omitted attributes removed from the database schema.
