The name of the geodatabase administrator user.

If you are using PostgreSQL, this value must be sde. If the sde login role does not exist, this tool will create it and grant it superuser status in the database cluster. If the sde login role exists, this tool will grant it superuser status if it does not already have it. The tool also creates an sde schema in the database and grants usage on the schema to public.

If you are using Oracle, the value is sde. If the sde user does not exist in the Oracle database, the tool will create it and grant it the privileges required to create and upgrade a geodatabase and disconnect users from the database. The tool also grants privileges to allow data imports using Oracle Data Pump. If the sde user exists, the tool will grant these same privileges to the existing user.

Creating or upgrading user-schema geodatabases in Oracle is no longer supported.

If you are using SQL Server and specified an sde-schema geodatabase, this value must be sde. The tool will create an sde login, database user, and schema and grant it privileges to create a geodatabase and remove connections from the SQL Server instance. If you specified a dbo schema, do not provide a value for this parameter.
