HAQM RDS Custom for SQL Server now supports Windows Authentication for DB instances

HAQM 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 HAQM Elastic Compute Cloud (HAQM EC2) and AWS Managed Microsoft AD.

Automatic reconnection to HAQM RDS for Oracle read replicas during disaster recovery

HAQM RDS for Oracle offers ease of operability, maintenance, scalability, and reliability while migrating Oracle workloads to AWS. The read replica in HAQM 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.

Migrating tables from IBM Db2 for z/OS to HAQM RDS for Db2

HAQM RDS for Db2 is the latest addition to the HAQM RDS family of database engines.
