   By default, DDM allows you to modify the instance parameters in Instance Parameters.

   In special scenarios (such as data migration), if you need to modify more instance parameters, submit a request by choosing Service Tickets > Create Service Ticket in the upper right corner of the management console.

   The following are parameter configuration examples.
