After creating a Oracle Instance on Amazon RDS I'm trying to import data by following the instructions here for Oracle SQL Developer - Database Copy:
http://aws.amazon.com/articles/Amazon-RDS/4173109646282306
My DB size is approximately 50GBs. It was running fine and I could see the DDL progress, data migration, etc but now it seems like it's stuck on a table that has approximately 350k records. My questions are:
For anyone that has tried DB Copy to Amazon RDS for Oracle, how big is your DB and how long did it take?
Is it safe to kill SQL Developer and restart the process?
Any advice is greatly appreciated!

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.
I have an instance of Oracle on PROD VPC (in AWS) and a postgreSQL on DEV VPC (in AWS). I want to copy all tables from Oracle to postgreSQL. As they are on different VPC, I am currently using the below process:
Using data pump, export the tables from Oracle PROD and import them to Oracle DEV (on DEV VPC)
Use python to extract data from Oracle DEV in CSV format and load them to postgreSQL using COPY
Is there any other efficient way to do this copy? I am trying to copy all work schemas (DDL and data) from source to destination.
Thanks in advance!
You could use VPC peering to get rid of the copy.What is VPC peering
Next, the oracle foreign data wrapper is a marvel to use for this kind of work. It makes your oracle tables accessible from the postgres database and makes copying data a piece of cake. A nice little python script can always help if there are many tables to handle.
I'm trying to write a script that gets the Oracle container databases and their pluggable databases on a given server. I can get these handily enough when the CDB is open - but is there a way to get the PDB's of a closed/stopped container database? The databases are on Windows and I'm writing the script in PowerShell.
Any help would be much appreciated.
There is one scenario where in our target is to migrate oracle database to Azure SQL DB.
Currently I am evaluating multiple options to migrate the existing Oracle Db to the Azure SQL DB, for the same reason I could not decide how to handle this situation where in the source DB i.e. Oracle is having transaction data which is a kind of incremental load.
Should this can be handled with mere replication of DB? or performing some data migration steps would help me ? Here i can think of earlier approach as easier approach where in i need not to worry about the transaction updates happening inside the data.
Considering this which utility i should use to perform this kind of activity?
You can replicate your Oracle database to Azure using Oracle Golden Gate as a way to migrate your Oracle database to Azure SQL. Striim seems to be another good tools to move your database to Azure SQL.
I think you may use the SQL Server Migration Assistant (SSMA) for Oracle.
SQL Server Migration Assistant (SSMA) for Oracle consists of a client application that you use to perform a migration from Oracle to SQL Server and Azure SQL DB. It also contains an extension pack that supports data migration and the use of Oracle system functions in your migrated databases.
SSMA can converts the transaction processing:

Hope this helps!
I need to migrate an existing application's database into oracle RDS database in Amazon Web services.
I have the dump file which is residing on an EC2 instance. The dump has not been taken by me.Also I would like to know how can I take the dump so that it can be imported successfully. The EC2 instance has an oracle regular client.
I have set up the oracle RDS instance in AWS and I am able to connect to the server.
I would like to know how can I import the database dump on RDS.
I am using this command :
imp rdsuser#oracledb FILE=fulldb.dmp TOUSER=rdsuser FROMUSER=SYSTEM log=test.log buffer=100000
Any lead is appreciated.
Also I would like to know what is the best method to import an existing database:
1. to take dump.
2. Or to take the clone of all files of database ( that will require the downtime in the server).
Best strategy is to take dump then import it into RDS . If your DB size is too big then contact AWS guys for help .
