Why people usually don't upgrade?"You need to upgrade now as your release is out of Premier Support

already!!!"

"Upgrading just costs a lot!" "I don't see any benefits by

upgrading to a newer release"

"It will just introduce new bugs and issues"

"I'm happy with the features of Oracle 8i"

"We'll wait for the 2nd release only"

"Application is not certified"

12.1.0.2 as of March 31, 2015– http://tinyurl.com/CertOracleSAP

"The migration of all 16 German Electronic Income Tax databases to Oracle Database 12c in less than 10 months went smooth and fine. We are very satisfied with the performance and the robustness of Oracle Database 12c."

Anticipated Benefits of Consolidation• Reduce capital expenses

– Hardware– Real Estate– Power/Cooling

• Reduce management expenses– Backup/restore– Performance management/monitoring– Patching/upgrade

• Reduce attack surface


Consolidation Options• Data Center Consolidation

– Bring multiple systems into one building

• Virtualization– Run multiple OS instances on a single server

• Database Consolidation– Run multiple databases on a single server

• Schema Consolidation– Run multiple applications in a single database

• Multitenant– Run multiple application databases in a single container

Potential economies of scaleReduced number of network attack points

Isolation & agility for patching, securityHardware utilization may be betterExtra layer of software (including licenses)

Potential server efficiencyLess isolation for patching, security

Higher hardware utilizationNo isolation for tuning, patchingPotential security issues
