2. ORACLE-12C
This course is ideal for Database Administrators of small to medium
sized businesses. This Oracle Database 12c: Fundamentals for Developers and
System Administrators course helps you perform basic Oracle Database 12c
administration tasks needed to keep the database operational.

3. ORACLE 12C DBA TOPICS
• Relational Database Model and Installing Oracle database software (12c R1)
• Oracle Database Architecture
• Database storage
• Oracle Networking
• User Administration and Security
• Used Managed (Manual) Backup and Recovery
• RMAN Backup and Recovery
• Oracle database upgrades
• Oracle 12c New Features: Multitenant Architecture
• Oracle Data Movement Utilities
• Oracle Database Performance Tuning

4. ORACLE-12C ARCHITECTURE

5. NEW FEATURES OF ORACLE-12C
1. Pluggable Databases Through Database Consolidation:
Oracle is doing every thing to jump into the cloud bandwagon. With 12C, Oracle
is trying to address the problem of Multitenancy through this feature. There is a radical
change and a major change in the core database architecture through the introduction of
Container Databases also called CBD and Pluggable Databases (PDB).

6. 2. Redaction Policy:
This is one of the top features in Oracle 12C. Data Redaction in simple terms
means, masking of data. You can setup a Data Redaction policy, for example SSN field in a
Employee table can be masked. This is called redaction.
3. Top N Query and Fetch and offset Replacement to Rownum:
With the release of Oracle Database 12c, Oracle has introduced this new SQL
syntax to simplify fetching the first few rows. The new sql syntax "Fetch First X Rows
only" can be used
4. Adaptive Query Optimization and Online Stats Gathering:
With this feature, it helps the optimizer to make runtime adjustments to
execution plan which leads to better stats. For statements like CTAS (Create Table As
Select) and IAS (Insert As Select), the stats is gathered online so that it is available
immediately.

7. 5. Restore a Table easily through RMAN:
Earlier if you had to restore a particular table, you had to do all sorts of things like
restoring a table space and or do Export and Import. The new restore command in
RMAN simplifies this task.
6. Size Limit on Varchar2, NVarchar2, Raw Data Types increased:
The previous limit on these data types was 4K. In 12C, it has been increased to
32,767 bytes. Upto 4K, the data is stored inline. I am sure everyone will be happy
with this small and cute enhancement.

8. DATA BASE STORAGE
Overview
• Oracle Automatic Storage Management simplifies the relationship between database
and storage to ensure the best I/O performance for database workloads while
significantly reducing storage costs and complexity
• Oracle Partitioning enhances database manageability, performance, and availability
for a wide variety of applications by allowing tables, indexes, and index-organized
tables to be subdivided into smaller pieces and managed cost-effectively on different
tiers of storage to improve access performance

9. • Oracle Advanced Compression helps businesses manage data growth more cost-
effectively by automating data-management processes that maximize resource
utilization with compression rates of 2-4x across all types of data and applications to
save disk space and improve query performance
• Oracle Hybrid Columnar Compression differentiates Oracle Exadata Database
Machine and Oracle SAN and NAS storage systems by reducing the size of data
warehousing tables by 10x, and archive tables by 15x, improving performance and
reducing storage costs for primary, standby, and backup databases

10. Benefits
• Manage storage more efficiently
• Reduce overall storage costs
• Optimize storage performance
• Protect against data loss

11. Oracle Virtual Networking
Oracle Virtual Networking products virtualize your SAN and LAN infrastructure by
defining connectivity in software, giving you the flexibility and agility you need for
the cloud. By consolidating your SPARC and x86 systems into a single data center
fabric, you can reduce infrastructure complexity by up to 70% and cut OPEX by up to
50%.

12. Ethernet Networking
Oracle's Sun Ethernet line of networking solutions deliver Ethernet
fabric and connectivity between Oracle's Sun servers, storage, and applications for
the convergence and high performance required in the virtualized data center.

13. InfiniBand Networking
Oracle's InfiniBand network solutions deliver the application isolation
and elasticity you need to consolidate and virtualize enterprise business
applications and cloud computing infrastructures.

14. Storage Networking
For enterprise customers looking for superior I/O connectivity,
Oracle's storage networking solutions offer some of the fastest, most cost-
efficient host bus adapters, switches, directors, and routers on the market today.

15. Backup and Recovery with RMAN
As noted earlier, using RMAN gives you access to several data backup and
recovery techniques and features not available at all with user-managed backup
and recovery. The most noteworthy are:
• Incremental backups, which provide more compact backups (storing only
changed blocks) and faster data file media recovery (reducing the need to
apply redo during data file media recovery)
• Block media recovery, in which a data file with only a small number of corrupt
data blocks can be repaired without being taken offline or restored from
backup

16. • Unused block compression, where RMAN can in some cases skip unused datafile
blocks during backups
• Binary compression, which uses a compression mechanism integrated into the
Oracle database server to reduce the size of backups
• Encrypted backups, which uses encryption capabilities integrated into the Oracle
database to store backups in an encrypted format

17. Files That RMAN Can Back Up
RMAN can back up all database files needed for efficient recovery in the
event of a failure. RMAN supports backing up the following types of files:
• Data files, and image copies of data files
• Control files, and image copies of control files
• Archived redo logs
• The current server parameter file
• Backup pieces, containing other backups created by RMAN
