Limiting to the top two levels. Possibility of using only wheels or disks in standalone mode as lower nodes. Introduction of a new level in the hierarchy. This will allows a better partitioning of the system. The two systems are under a single top node as required by the CMS DCS Integration guidelines. The two systems can also work standalone.

/ Joint RPC- Trigger meetingP. Paolucci - I.N.F.N. di Napoli15 RPC DCS Integration Status We were successful in creating a first version of the CMS RPC sub- detector SUPERVISOR component using the tool provided by the JCOP framework. The RPC component contains both Endcap and Barrel trees, but it has been designed has two components that can work on different PCs. We accessed the Configuration DB. We are able to read from and write in it (in a private Oracle DB) using custom scripts with Framework functions. We still need to - know the coordinates of the DB we are going to use for the CC and test the best way to access the DB (different solutions are possible) - finish to prepare the hardware component (march 06) - work on the condition DB - temperature monitoring (waiting for JCOP FW)
