Cold and admin are different (old/new) names for the same state:
the kernel is running/the database software is running;
the dbm can do some things like restoring data/log, some diagnostic 
features and the like, but no sql;

To allow SQL-statements the database has to be in the warm/online-state
as written correctly. 
And from offline (no database software is working) or 
admin/cold-state (database software is running, only restricted functionality)
the db_warm/db_online/restart-command changes the state to online/warm.
