There is still a cron job that creates 100 copies of ccdb.sqlite on the work disk (gluex@sandd1.jlab.org).
They are chosen by build_scripts/calib_url_chooser.sh when the sqlite command option is specified. Do not know of any official instance where this is being used.
Also there is a reference in MCwrapper, but that appears to be commented out at this point.
At some point, should look at removing these or documenting the use of calib_url_chooser.sh as a way to point to a sqlite file.
