See the documentation for the @UpdateApplicationCatalog system procedure. It updates the schema and stored procedures on a running database.
http://voltdb.com/docs/UsingVoltDB/sysprocupdateappcatalog.php

Note that this capability is available in the Enterprise kit only. For the open source version, you must first take a snapshot (to save your data), shutdown the database, and restart with the new catalog.
