3.
Why Oracle 12c
• Oracle Database 12c is designed for the cloud and introduces
Multitenant Architecture with more than 500 new features.
• Multitenant architecture featuring pluggable databases, which makes
it easy to consolidate your databases on to the cloud, deliver high
density of schema based consolidation
• It enables customers to increase utilization of resources, and rapidly
provision and clone database for various purposes by lowering down
of Infrastructure & administrative costs.

4.
Multitenant Architecture
• Multitenant container database can hold many pluggable databases. It
manages many databases as one and retains the isolation, resource
control of each database. This will help to manage both Infrastructure
and human resources effectively.

5.
Managing Many Databases as ONE
• Fewer Backups
– With Oracle 12c, you don’t need to back up each database
separately.
– The new pluggable architecture only requires you to perform a
backup at the multitenant container level. That means you will
have fewer backups to manage as each pluggable database
backup with container.
– You’ll have the flexibility to perform the recovery operation at the
pluggable database level or container level.

6.
Managing Many Databases as ONE
• Fewer Patches and upgrades
– With Oracle 12c, you don’t need to apply a patch, patch set, or
product updates to multiple databases separately.
– All these can be applied at the container level and not at each
individual pluggable database level.
– Consolidating the multiple pluggable databases into a multitenant
contain can reduce the amount of patching and upgrade activities

7.
Managing Many Databases as ONE
• Fewer Standby Databases
– With Oracle 12c, you don’t need to ship and apply redo logs
separately on each standby.
– You can apply the redo logs at container level and every pluggable
database in a container is fully protected from outages and uses
can also use their standby pluggable databases for reporting
purpose

8.
Managing Many Databases as ONE
• Oracle multitenant is fully compatible with existing database options
and features such as Oracle Real Application Cluster, Active Data
Guard, Real Application Testing and Recovery Manager

9.
Advantages of Oracle 12c
Oracle 12c makes easier for customers to take advantage of the cloud
through
• Pluggable Database
• Consolidating Database
• Rapid provisioning and cloning
• Automatic Data compression
• Continuous Business operation
• Comprehensive security & compliance
• Simplify Big Data Analysis
• Resource allocation Controls

10.
Pluggable Database
• The pluggable databases gives the opportunity for consolidation.
• It allows running multiple databases as ONE by shrinking hardware
footprint.
• simplify the management of Oracle Multitenant database creating,
resource management, backup/recovery, problem analysis…etc.

11.
Consolidating Database
• Many pluggable databases into a single multitenant container
database by sharing its memory and background processes
• Reduce patching and upgrade activities by increasing server
virtualization with high density database consolidation per server

12.
Rapid provisioning and cloning
• You can plug and unplug the database and move database rapidly
across the different containers.
• Provides flexibility of creating new patched or upgraded containers
and selectively unplugging database from older container and
plugging database into a new patched or upgraded container.
• In single step you can close a database instantly

13.
Automatic Data compression
• Automatically age out older data and store it on different storage
compression level tiers.
• The Heap map feature in Oracle 12c tracks usage information at row
and segment level, applying policies to automatically move and
compress database objects based on the age and activity of the data.
• Oracle Advanced compression will help to reduce storage
requirements of large OLTP tables or partitions containing “Hot”
frequently updated rows by 2-4x and Oracle Hybrid columnar
compression provides up to 10x compression for “warm” read-only
data and up to 50x compression for “cold” archival data.

14.
Continuous Business operation
• Oracle 12c provides continuous access with Oracle’s Maximum
Availability Architecture.
• For Application Continuity from database failures, it makes better user
experience by enabling transaction replay in a non-disruptive manner
following a recoverable database failure.

15.
Continuous Business operation
In order to prevent and mitigate unplanned down time Oracle 12c offers
many high availability components, here are few:
– Oracle Automatic Storage Management (ASM) : Protects from
Database storage failures
– Oracle Real Application Cluster (RAC) : Protects from Database
server failures
– Oracle Flashback : Protects from human errors & reduce recovery
time
– Oracle Active Data Guard : Protects from site failures and offload
processing
– Oracle Recovery Manager (RMAN) : Comprehensive foundation
for efficient Database backup and recovery
– GoldenGate : Real time data integration and replication

16.
Continuous Business operation
In order to reduce planned downtime, Oracle 12c offers many solutions:
– Online Patching
– Online Redefinition
– Rolling Database Upgrades
– Hardware Maintenance and Migration operations
– Edition Based Redefinition

17.
Comprehensive security &
compliance
Oracle offers multi-layered approach to protect enterprise data from
hackers, other groups intent to steal data and provide customers the
relevant preventative, detective and administrative controls which
includes:
– Transparent encryption of data using Oracle Advanced Security
– Separation of duties and latest privilege preventative controls
using Database Vault
– First line of defense of databases and consolidated audit trails
using Oracle Audit Vault and Database Firewall
– Comprehensive administrative controls such as Enforce password
complexity, Monitoring accounts, Manage privilege entitlements,
tracking and up to date of security patches.

18.
Simplify Big Data Analysis
• Oracle 12c provides comprehensive analytics and data integration in a
single platform that meets Enterprise Business demanding needs.
• It supports wide range of tools including OLAP aggregation, advanced
indexing, partitioning elimination, automatic query transformation
and parallelize database operations.
• Oracle 12c provides
– Oracle Data integrator and Oracle Big data connectors for Big data
integration
– Oracle Database features such as In-Database Graph, In-Database
MapReduce, SQL Pattern Matching, In-Database spatial and open
source R algorithms for In-Database analysis
– Oracle Exadata Machine, Oracle Big Data Appliance, Oracle
Exalytics In-Memory Machine for Big Data Infrastructure

19.
Resource allocation Controls
• Define resource utilization at pluggable database level and pull system
resources when required from low priority applications in a container
by ensuring performance service leave remain consistent.
• Oracle 12c offers Global Data Services (GDS) for automated workload
management solution.

20.
Upgrade path to Oracle 12c
• Oracle 12c provides to enhanced upgrade automation, the pre-
upgrade and post-upgrade steps have been enhanced by providing fix-
up scripts to reduce the manual work.
• Oracle 12c offers two upgrade options to customers, which is
upgrading to new Multitenant architecture or current architecture.
– Customers have a direct upgrade path from Oracle Database 11g
R1/R2 and Oracle 10g R2.
– Customers who are on Oracle 10g R1 and earlier can use tools
such as Data Pump and GoldenGate to migrate data to Oracle 12c.

21.
Upgrade path to Oracle 12c
• Direct upgrade support at Patch set level
• There are various tools available to upgrade or migrate the database,
such as Database Upgrade assistant (DBCA), Command-Line upgrade,
Data Pump Export/Import, Original Export/Import, Transportable
Tablespace.

22.
Oracle Enterprise Manage Cloud
Control
• Oracle Enterprise Manager provides business value by leveraging the
built-in management capabilities for traditional and cloud
environments.
• The key capabilities include:
– Maximum return on IT investment through Oracle engineered
systems with real-time integration
– Business-driven application management provides best service
levels for traditional and cloud applications
– A complete cloud lifecycle management solution allowing you to
quickly set up, manage and support enterprise clouds and
traditional environments
