Barrel and Endcap projects are readyTwo PCs running the projects are at 904 Integration with CMS DCS is almost ready, some common problems still to fix

RPC DCS will be ready for May 2006



Next Steps

CMS_RPCSince the last meeting:• The endcap is up to date with the barrel and the two systems are proceeding in parallel• Tests on CPU and RAM usage have brought us to reduce the number of CUs. 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.

• 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)
