Amazon RDS provides different instance types optimized to fit different relational database use cases. You can modify provisioned instances manually from the Amazon RDS console or using an API. When modifications need to be done on a recurring basis, such as scaling an instance up and down during predefined periods of time, you can automate the task using EventBridge Scheduler and Lambda. In this post, we present a solution using Amazon EventBridge Scheduler and AWS Lambda that allows you to schedule a programmatic modification of a DB instance with specific tags.

This post outlines a set of design and tuning strategies for a high-speed purge in an Amazon Relational Database Service (Amazon RDS) for MySQL DB instance and Amazon Aurora MySQL-Compatible Edition DB cluster. Purge is a housekeeping operation in a MySQL database. The InnoDB storage engine relies on it to clean up undo logs and delete-marked table records that are no longer needed for multiversion concurrency control (MVCC) or rollback operations.

Scopely is a global games developer, operator, and publisher with operations across North America, Central America, EMEA, and Asia, and additional studio partners spanning four continents. Over the past year, Scopely has served more than 500 million players with major titles such as “MONOPOLY GO!,” “Stumble Guys,” “MARVEL Strike Force,” “Star Trek Fleet Command,” and “Scrabble GO.” In this post, we showcase how Scopely used CloudBasix to enable migration of “Stumble Guys” high-volume backend transactional databases with minimal downtime from Azure SQL database to Amazon RDS for Server.

Amazon RDS Custom for SQL Server now allows you to directly join your DB instances to the domains of Microsoft Active Directory (AD). In this post, we show how to join RDS Custom DB instances to an AD for Windows Authentication. This applies to AD domains running in a self-managed environment either on premises or Amazon Elastic Compute Cloud (Amazon EC2) and AWS Managed Microsoft AD.

Amazon RDS for Oracle offers ease of operability, maintenance, scalability, and reliability while migrating Oracle workloads to AWS. The read replica in Amazon RDS for Oracle is a physical copy of the primary database that can be set up either in mounted or read-only mode. In mounted mode, the replica instance isn’t open for read operations, however in read-only mode, it allows read operations on the replica instance. During managed Oracle Data Guard Switchover with Oracle RDS for Oracle, the database role reversal takes place between the RDS for Oracle primary database and its replica. Similarly, in case of a disaster, you can promote the read replica to a standalone instance. In both scenarios, the application needs to point to the endpoint of the new primary database to establish connectivity. In this post, we provide guidance to configure the automatic reconnection of the application to a standby database during a disaster recovery incident while using replication with Oracle Data Guard using Oracle services and a TNS names connection alias.

In this post, we discuss how to determine the causes of an INCOMPATIBLE_CREATE state of an RDS Custom instance because of incorrect instance profile permissions.

Amazon RDS for Db2 is the latest addition to the Amazon RDS family of database engines. When it comes to selecting the relational database to migrate data from Db2 for z/OS, RDS for Db2 provides the best compatibility among other relational database management systems (RDBMSs) thereby minimizing the migration effort and timelines. In this post, we outline the migration methodology for converting schema and data from Db2 on z/OS to RDS for Db2.

Amazon Relational Database Service (Amazon RDS) for SQL Server makes it straightforward to set up, operate, and scale SQL Server deployments in the AWS Cloud. The service allows DBAs to focus on high-value tasks such as query optimization, query construction, and schema design rather than time-consuming database administration tasks including provisioning, backups, software patching, monitoring, […]

In this post, we show you an analysis tool which serves as a starting point to your database analysis journey by highlighting specific interdependencies between database objects: object dependencies, object constraints, and trigger references. Through a combination of SQL queries on the source Oracle database dictionary and Excel filters, the solution in this post can capture interdependent database objects for a target schema and generate a visual dependency diagram.
