, why these dictionaries are locked, probably because there is no configuration to tell the server user, so the system needs to go to each PDB to query the system fields, just In Pdb_sa, there are some reasons for being stuck (guessing, because of a lack of conditions, so querying these fields is time consuming) WORKAROUND: Provide the complete statement Create User by "123456"
