AWS and Amazon RDS provide advanced features and architectures that enable graceful migration, high performance, elastic scaling, and high availability for Oracle database workloads. Learn best practices for realizing the benefits of the cloud while reducing costs, by running Oracle on AWS in a variety of single- and multi-instance topologies. This session teaches you to take advantage of features unique to AWS and Amazon RDS to free your databases from the confines of the conventional data center.

13. AWS Database Migration Service best practices
Use dbms_metadata.get_ddl or
SQL Developer for schema
Divide schema DDL into 2 parts
Apply secondary indexes and
triggers after data load
Choose bigger C4 instances
Optimize network path

14. Building fast, scalable

25. Amazon RDS for Oracle I/O best practices
Amazon RDS maximum channel
bandwidth: 1000 Mbps each direction
= ~105MiB/s per direction and ~210MiB/s for a 50%
read/50% write balanced workload
First touch penalty for network-attached
RDS storage
Small general purpose SSD
Storage sizes (~30Gb) deliver low
baseline I/O throughput

26. Building Oracle RAC on AWS

27. RAC on Amazon EC2 would be useful
• Test / dev / non-prod; allow testing to cover RAC-related regression cases
• Scale out and back elastically; a good match for the cloud
• Scale beyond the largest instances
• High-RTO redundancy at the host/instance level; App continuity for near zero downtime
• Test scaling limits; a given workload scales only to n nodes on RAC
• Some applications “require” RAC
• Some customers don’t want to re-engineer everything just to move to AWS
• Customers want it!
