Create Images & Subscribe Define end states for software as Images. Subscribe targets/ groups/pools to the images

Image represents the End-state Definition for Oracle Database 11.2.0.3 on Linux x86_64 + OCT 2013 PSU patch +5 one-off patches


Target (s)

Subscribes to

Software “End State” Gold Image



3 Centralize changes and propagate with ease

Make changes at Image level. Schedule the propagation to the subscribed members.

Software “End State” Image - Versioning

OCT 2013 - OCT PSU + 2 patches Ver. 1

DEC 2013 - Add 5 more patches Ver. 2

* Current / Latest version

JUL 2014 - Jul PSU + couple more patches* Ver. 3*



Database Fleet Maintenance

• Allows emergency, ad-hoc patching.

• Ad-hoc is more an exception than a norm, its tracked as ‘Rogue’

• Reconcile the rouge targets either by rolling the changes to a new version of the image or override it with the latest version.

Rouge Target

Update to new version or rollback to older

Manage Exceptions and Emergencies



Process

1. Pools subscribe to DB and GI images

2. New images automatically get deployed to servers in the pool

3. Self Service users or Admin can choose to migrate DBs over to the new home

Benefits:

– Scale: Subscription based, automated deployment and at mass scale

– Reduced Downtime: Out of place patching and upgrade

– Isolation & Flexibility: Users to move to new software version on their terms

Maintenance as a Self service option. End users can update during their comfortable time periods

Reduced Downtime

Detect the Configuration Pollution

Advisor scans the fleet for configuration variations, provides recommendations to standardize

Abstraction between software and configuration. Replacing updated software for changes reduces or removes downtime.

Automation at Scale

Create Images & Subscribe

Define end states for software as Images. Subscribe databases /groups/pools to the images

Make changes at mass scale. Deploy updated software (minor and major updates) images to the entire pool
