To import data into the RDS oracle database or export data from it, we need to consider the size of the data involved and use a appropriate technique. The Sql Developer tool which we use to connect to AWS RDS oracle instance, can be used for both export and import small volume of data like 20MB or so. But to import data of size in terabytes, we need to use oracle data pump.
After connecting to the AWS RDS Oracle DB, choose tools and Database Export.
The next step asks for the type of export where we decide the export format.
Next we decide on the DB objects to be exported.
We can further decide on the name of the objects to be exported.
We can further decide on the objects attributes to be exported.
Finally we get the summary screen where we can revisit the objects we have choosen.
Clicking finish on the above step will export the DB into a file in choosen format.
Similar to the export steps above we can choose to import the db by using Database Copy command from the Tools menu option.
