I have a T class Oracle Standard Edition Two RDS. I am trying to create a read replica for it but the option is missing. I so have the backup retention enabled. Is it not available for this edition of Oracle DB?

I have a couple of questions on AWS RDS service for migrating an oracle 19c server on RHEL with 3 standalone instances and databases:
Can RDS instance support multiple oracle standalone instances/databases or only one instance?
If I have an existing RDS service running in AWS, can I migrate another on-premise oracle database to the RDS database as another oracle schema?
Have not tried it yet.
RDS for Oracle limits one instance to a single database. However you can have multiple schemas in one database.
An account can have up to 40 BYOL type Oracle RDS instances, or up to 10 instances where license is included. You can also increase these limits by contacting AWS support.
See here for more details.
Each RDS instance equals one database. However, you can set up multiple RDS instances, if you want to.
For migrations, please have a look at the Database Migration Service (DMS). Regarding your schema in particular, please check the Schema Conversion Tool which is a part of the DMS.
Sorry I can’t be more specific as the questions are rather vague themselves.
Ok, so this morning it seems that Oracle RAC shows up as an option when creating a RDS Custom. The only problem is that it doesn't show any custom engine versions and it seems it is required to have them. Now I have a couple of Oracle custom CEVs so what gives? If I click in and create a new CEV the only option is Oracle Enterprise Edition. Even if I click in and create it from here it still won't show up when I want to create the Oracle RAC. Is AWS just teasing us or what?
I have an Oracle SE database that we run in Amazon's RDS service as our production database. I am looking for techniques and/or tools to duplicate the database to a developer edition database that the development team can run on their local systems.
You can generate dump file and transfer it to your local/standalone unix system where oracle is installed. and then import dump file data.
You do not have direct access to the RDS instance file system.
There are several data migration solutions.
The first solution using S3 Bucket.
Use DBMS_DATAPUMP to export to DUMP File on the RDS Instance.
Copy Dump File from the RDS instance to Amazon S3 Bucket.
Download the dump file from the S3 cloud to the developer edition database.
Import data from the dump file using expdp on the developer edition database.
The second solution using Database Link between the RDS Instance and the developer edition database.
Create a Database Link on the RDS Instance to the developer edition database.
Use DBMS_DATAPUMP to export to DUMP File on the RDS Instance.
Use DBMS_FILE_TRANSFER to Copy the Dump File from the RDS Instance to the developer edition database.
Import data from the dump file using expdp on the developer edition database.
The third solution using Oracle XE, if you cannot make a db link between the developer edition database and RDS instance.
Use DBMS_DATAPUMP to export to DUMP File on the RDS Instance.
Create a free instance of EC2(1 CPU core, 1G RAM, 30GD HDD ) or a
paid instance with a large disk and CPU.
Install a free database version of the Oracle XE version on EC2
instance.
Create a Database Link on the RDS Instance to the Oracle XE.
Use DBMS_FILE_TRANSFER to Copy the Dump File from the RDS Instance to the Oracle XE.
Copy files from the Oracle XE on EC2 instance via the sftp protocol on your PC.
Copy files from your PC to the developer edition database.
Import data from the dump file using expdp on the developer edition
database.
And other solutions without using DATA PUMP:
Export/Import Using Oracle SQL Developer.
Oracle Original Export/Import Original Utilities
I'm have created the oracle RDS with Bring your own license, But not getting anything? where i can add my existing oracle DB licence to oracle RDS.
I have tried with SQL developer there is no any option for this.
So, Is there any other way to ad the license to Oracle RDS?
Oracle doesn't use software keys. It is only "right to use" (RTU) the software.
I am new to AWS DMS service. Plans are to migrate on-prem Oracle to Redshift. Before going into production environment, currently trying out a test Oracle RDS in AWS which is a small subset of actual database as source. So far have been successful in the bulk load and incremental migration from RDS to Redshift.
When it comes to on-prem oracle , particularly for the incremental load
1) As per document : http://docs.aws.amazon.com/dms/latest/sbs/CHAP_On-PremOracle2Aurora.Steps.ConfigureOracle.html, the on-prem needs to be enabled with supplemental logging. Plans are to use the following two commands.
ALTER DATABASE ADD SUPPLEMENTAL LOG DATA;
ALTER DATABASE ADD SUPPLEMENTAL LOG DATA (PRIMARY KEY) COLUMNS;
The production database has multiple logging locations. Is there any other log settings other than the above two that I should be looking into for DMS to pick up multiple log locations?
2) In the same link given, point 4 says 'Create or configure a database account to be used by AWS DMS.'
Where should I create this user? on-prem oracle or AWS?
How do I configure DMS to use this user?
You need to read this documentation:
https://docs.aws.amazon.com/dms/latest/userguide/CHAP_Source.Oracle.html
For your second question; You need to create a user in the Oracle source database, the section 'Working with a Self-Managed Oracle Database as a Source for AWS DMS' tells you all of the grants you need to give.
For your first question, if you look at the SQL Server documentation;
https://docs.aws.amazon.com/dms/latest/userguide/CHAP_Source.SQLServer.html
It specifies the limitation of; 'SQL Server backup to multiple disks isn't supported. If the backup is defined to write the database backup to multiple files over different disks, AWS DMS can't read the data and the AWS DMS task fails.'
I can't see a similar stipulation in the oracle documentation, first link, I would hazard a guess that DMS is able, in the case of oracle, to determine and cope with multiple logging locations from a configuration value inside the database.
