      When the secondary node applies the onDatabaseMetadataUpdate oplog 'c' entry, it can either call clearDbInfo or setDbInfo, depending on the DDL operation it is reacting to. In order to execute both methods, we need to have acquired the DSS in exclusive mode.

      This ticket aims to investigate whether it is also necessary to acquire the MODE_X lock on the database or a less restrictive mode.
