Migration – RDS Planning

• Which Oracle edition should I choose?

• Enterprise Edition, Standard Edition or SE1 (BYOL)

• Optimize cost with Oracle SE1 with license included

• Review RDS Oracle documentation

• User Guide http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Welcome.html

• Common tasks DBA tasks for the Oraclehttp://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Appendix.Oracle.CommonDBATasks.html

Instance Selection

• RDS offers a wide range of instance classes

• Instance types differ on CPU, RAM, network

performance, EBS Optimized

• Base selection on

• Performance

• Cost (will differ based on type and region)

• Region (not all instance types available in all regions)

• Elastically scale instance size up/down

Recommendations

• Take advantage of Data Pump options

• Choose the largest RDS instance. Once the import is

done change the RDS instance to your preferred type

• For the import, only choose single AZ. Once the import is

done you can enable multi-AZ

• P-IOPS will improve import performance

Adopting RDS Oracle SE1

Oracle Enterprise – the data engine for MarketLive sites

•Oracle Enterprise Clusters

• Sun Sparc Clustering

• Multiple Instances

• Multiple Schemas

• Schema per Merchant

•Dataguard Standby

• Offline reporting

• Warm Site Standby

• Disaster Recovery

•Online indexing

•OLTP performance

•Catalog repository

AWS Required Rethinking Deployment of Oracle

•Discovery

• Enterprise features in use

• Alternatives in RDS Oracle SE1

• Migration gaps to SE1

• Learning curve for DBAs

•Deployment changes

• SE1 for cost + flexibility

• Management operations

• Monitoring deployment

• Sync solution

22

Comparing Enterprise and Standard Edition 1

Oracle Enterprise

•Dataguard replication

•Direct access to the OS for

scripting, cron jobs

•Database migration across

license types

•Online indexing

RDS Oracle SE1 at AWS

•RDS snapshots

•Attunity replication

•Jumpbox approach

•RDS console operations

•Attunity moves data from

Enterprise to SE1 seamlessly

•Maintenance required for new

indexes

23

DBA Learning Curve

•Getting over not being able to log into the RDS instance itself

•Workaround for lack of EXPDP, still learning the AWS-way to make

this a smoother process

•Changes in naming conventions, operations practices when

moving from large cluster instance to instance per merchant

deployment

•Re-implementation of some monitoring scripts that are part of

database management practices at MarketLive

•Re-factoring post stored procedure script execution

•Maintenance required for new index creation on large tables

24

Lessons Learned

•Take advantage of the AWS RDS team!

•Give DBAs familiar with Enterprise enough time to work through

the changes in operation required to downshift to SE1 (but don’t

accept that there is a task that “can’t be done”)

•Dig into the features and functions of the RDS console and practice

with it in a test environment so you know what to expect in terms of

time and operation

•Take advantage of RDS Business Support – excellent response and

expertise
