I'm trying to create a user/schema enterprise geodabase using the Create Enterprise Geodatabase geoprocessing tool. In the tool, the database administrator (DBA) & DBA password are marked as "optional"; however. the documentation states you HAVE to login as DBA ('sys' in Oracle) in order to create a user/schema geodatabase. We are attempting to test replication in Oracle RDS on AWS and do not have access to the "sys" account so I'm not sure if there is a workaround if these are "optional". Is anybody using Oracle RDS in AWS as their enterprise geodatabase? Thank you for any information anyone might have about the possibility of working around this complication in Oracle RDS.
