Dear all, Currently mysql://clas12reader@clasdb-farm.jlab.org/clas12 is not working. As a consequence, gemc will not work after a module load clas12. As a temporary workaround until the server is fixed you can either: unset CCDB_CONNECTION or export CCDB_CONNECTION=mysql://clas12reader@clasdb.jlab.org/clas12 Best, Mauri
