DIM-00019 error

Ensure that you are using an appropriately privileged account when attempting to create the database. This error occurs when the Database Configuration Assistant cannot successfully create the instance and/or service. Review the oradim log and the database alert log (if one exists) for any errors.

You could also attempt to create the service manually using oradim rather than through the DBCA. To find options for the oradim command, simply type

oradim

at the DOS command prompt. You should see some help displayed for how to use oradim. Your command to create the service will look something like this:

oradim -new -sid <sid_name> -intpwd <password> -startmode <auto> 
-pfile d:\orant\database\init<sid_name>.ora
