How do i copy snaphsot of one RDS instance to another? - amazon-rds

We are in the process of creating new RDS instances with the encryption option enabled. Once new RDS instances are created, we need that to have same data as old ones. We have daily snapshots on all of our RDS instances. Is there a way to copy this RDS snapshot to newly created RDS instance?
One option for me is to take mysqldump of each database in old RDS instance and add it to individual databases in new RDS instance. This is time consuming as each database snapshot comes to 40-50 GB.
Please let me know if there is any easy way to copy that snapshot and put it on new RDS.

An Amazon RDS snapshot contains a complete copy of the data in your RDS instance.
The snapshot can be used to create a new Amazon RDS instance. It will then contain a complete copy of the data from the snapshot. However, note that this process creates a new Amazon RDS instance. It cannot be used to "insert" the data into an existing Amazon RDS instance.
See: Restoring From a DB Snapshot

It may be possible to configure RDS snapshots into a new RDS instance. Assuming that your RDS configuration is the same for both instances and preferably the same region, You can try to launch a new RDS DB onto your second account (instance).
Depending on the configuration and If your RDS Instance is publicly accessible:
Install the appropriate DB management tools onto a PC, and give this PC network access to both RDS instances (security groups and DB user access for read and write)
Using the database management tools to copy the data from one DB to the other DB
(or) Copy data through an EC2 instance as an intermediary:
Launch an EC2 instance configured with appropriate DB server software
Copy the RDS DB Data from your RDS instance up to your EC2 instance
Then launch your new RDS instance into the second account
Configure appropriate access (security groups and DB user access for read and write)
Copy the database data from your EC2 instance to your newly created RDS instance
If the RDS instance and the EC2 instance are in the same availability zone, try passing a bash script to the (linux AMI) EC2 instance as user-data, and the details of data transfer can be handled in the script.

Database migration from AWS Aurora Serverless v1

We have a plan to create a new application, which won't have the same architecture of the current one, and will definitely have some differences in the tables' schemas. Our current application's database is running on a AWS Aurora Serverless v1 cluster, with MySQL 5.7. We need to migrate data from the old application to the new one, making some schema changes in some places.
One solution is to create dumps of the old tables, in an easily readable format like csv, then import the data in the new application, picking the data as needed. This will require writing bespoke code on both applications to export data from one and import it into the other.
Considering that we are in AWS, and we intend to keep using it, choosing Aurora as a database (we'll have to decide whether use a provided solution or go with Serverless v2), is there any service to export data from one Aurora Serverless v1 cluster to another Aurora cluster, making changes along the way?
I know that database snapshots exist, but that's not exacly our goal. We need to migrate data from one database to another, not creating another copy of the first one. I've seen that there is a service, called "AWS Database Migration Service", that's used to migrate data into RDS, but does this service suit our needs, to get data from one Aurora Serverless database, do some changes, and then put it into another RDS database of our choice?
You could use following options to accomplish your goal.
1.- AWS Database Migration Service, this service provide you capabilities to replicate your data and also perform some schema transformation during replication process. You can create selection and transformation rules, the service will execute those rules and apply changes to the target schemas. You could review more details on this link.
https://docs.aws.amazon.com/dms/latest/userguide/CHAP_Tasks.CustomizingTasks.TableMapping.SelectionTransformation.Transformations.html
2.- AWS Glue Studio, it is ETL service that allows you extract, convert and transfer data between source and target databases.

how to transfer/migrate data from Source Oracle DB to aws oracle rds

I have a request to move Source Oracle DB into AWS Oracle RDS. I research on AWS page to find out the solution, but AWS guide very complex such as upload dump file to S3, download file dump...I don't want to do on this way because it very take time. Any one have any solution to move database to AWS Oracle RDS?
My updated: Source Oracle DB is not use any AWS service. It only installed on phycical server.
Please help share any solution/tools can use to migrate
You can use the AWS native Database Migration Service (AWS DMS). Below is the link to the AWS DMS workshop.
https://catalog.us-east-1.prod.workshops.aws/workshops/77bdff4f-2d9e-4d68-99ba-248ea95b3aca/en-US/oracle-oracle/data-migration
In the link, source database is mentioned as AWS RDS, but you can connect to any source database at on-premises or other locations. All you need is connectivity (between source Oracle and AWS target RDS Oracle) along with source database host IP, database port and db user credentials with necessary permissions to pull data from source. Usually for database migrations a direct connect is recommended to avoid data transfer related issues, but can also be done over VPN (can be slow for large migrations)
Start with the pre-requisites (permissions, grants etc.) to prepare the source database for migration as mentioned in the link above.
Other tools to explore would be to use Database native tools, like for Oracle we get Data Pump (export/import), for which we will have to use S3 for dumping the source data and then importing into AWS RDS from S3. This may be ok for one time activity. But for large number of migrations AWS DMS with a stable connectivity is the way to go.
Third option I can think of is use of AWS Snowball, if there is no reliable connectivity between source and AWS for large data transfer. AWS Snowball edge storage can be requested to your db location and hooked up to the network. Dump the database export into the Snowball and ship it back to AWS. They will copy the DB dump to a S3 bucket and from there we can import it into RDS.
Hope that helps...
You can use SQL Developer Tool to copy database from source to AWS Oracle RDS (I am using SQL Developer Tool version 19.2.1.247)
Before migrate you need the below things to prepare/configure on AWS Oracle RDS, to ensure the same with Source Oracle DB
Create the same user who assigned to your schema/database
If Source Oracle DB is using tablespace, you must be create the same tablespace
After prepared, You will do the below steps on SQL Developer Tool
Using admin account to created a connect to Source Oracle DB server.
Using admin account to created a connect to Oracle AWS server.
Go to Tools -> Database Copy...
On Dialog, choose source db and destination db
INFO:If you are using tablespace on source db, you must be choose [Tablespace Copy] like that:
Click Next to continue and waiting to transfer.

How can a java application running within a Fargate container connect to Aurora Postgresql db?

We have a java application running in a Fargate container and this application needs to connect and have limited access to the Aurora Postgesql DB.
How can this java application connect to Aurora Postgres DB?
I thought of creating a user account within the db and assigning policies but I need this to be done using Terraform.
Is my approach right? if yes how do we create a user account in Aurora Postgresql db using Terraform.

Amazon RDS - How to Create new DB using PHP API?

In a SAAS app, written in PHP, how to create a new mysql database in an existing RDS instance?
The documentation for php api here:
http://docs.aws.amazon.com/aws-sdk-php/guide/latest/service-rds.html
doesn't show any such function available under available operations section at the bottom.
How do we do that??
There is no such option provided in RDS API. When you call CreateDBInstance API, you can specify the DBName but that is at the time of creating a new RDS instance. Once you have created the instance, then there is no provision to create a new DB on it.
I would imagine you need to connect via PHP using ODBC (or whatever that PHP supports) to the RDS endpoint and then create a new DB just like you are connecting to a non-RDS remote DB.

Replicate Amazon RDS for non-LIVE support purpose

We have a web application which is hosted on EC2 (Apache in Ubuntu) with MySQL DB in RDS (Multi AZ). We are planning to go for another application instance which will primarily be used by our support team to analyse certain LIVE issues. In order to do this, we would like to have a copy of LIVE DB data in another instance, preferably in another RDS instance. Here is our approach:
Get the latest RDS snapshot
Create a new RDS instance, and copy the RDS snapshot into it
Set up the application configuration to point the DB to the new RDS instance created above
Could you please share your comments on whether this approach is fine, or is there a better approach?
By the way, I checked following stackoverflow questions:
How to copy a database using RDS
Amazon RDS replica
In both these questions, mysqldump is suggested. But in my case the DB size will be huge, and mysqldump might slow down the LIVE performance.
Take a look at AWS read replicas. See http://aws.amazon.com/rds/mysql/#Read_Replica
