7. “it enables read-only access to a
physical standby database for
queries, sorting, reporting, webbased access, while continuously
keep applying all changes received
from the primary database.”
ACTIVE DATA GUARD
11G NEW FUNCTIONALITIES

8. “Compresses any type of data
(structured and unstructured data),
as well as network traffic, memory
utilization and inclusive the amount
of data in the process of being
backed up”

OLTP compression – It allows structured and unstructured data
to be compressed on INSERT, UPDATE and DELETE operations.
RMAN Backup Compression - Compress RMAN backups.
Datapump export compression - Compress datapump export
files.
SecureFiles Deduplication - Detect and eliminate duplicate
copies of files stored within the database.
SecureFiles Compression - Compress unstructured file data
within the database.
Network Traffic Compression - Compress Data Guard redo data
as it is sent over the network.

11G NEW FUNCTIONALITIES

10. OLTP Compression
When Loading Data

11. OLTP Compression
When Reading

12. OLTP Compression
When Inserting (Part II)

13. ADVANCED COMPRESSION
11G NEW FUNCTIONALITIES

14. “allows businesses to quickly
adopt new technologies while
eliminating the risks
associated with any change “
“it combines a workload capture and
replay feature with an SQL
performance analyser to help you to
test the changes against real-life
workloads, then it will help you to
fine-tune them before putting them
into production”
RAT
Real Application Testing

15. “ Indexes that are ignored by the
optimizer. Handy for testing without
dropping “
INVISIBLE INDEXES
11G NEW FUNCTIONALITIES

16. “Virtual Private Catalog
and Import Catalog”
“Recovery Advisor”
RMAN> LIST FAILURE;
RMAN> ADVISE FAILURE;
RMAN> REPAIR FAILURE;
<PREVIEW><NOPROMPT>
RMAN
What is New
“Active Database
Duplication”

17. “Multi Section
Backups”
“Tablespace Point
in Time Recovery”
“Duration”
Backup duration 00:30 database;
<minimize time>
<minimize load>
RMAN
Some more cool stuff

18. “Validate Database”
“Archival Backup”
Any time this command detects a
database failure, it initiates a
failure assessment and logs the
failure in the ADR.
RMAN
“Backup Failover to
Non-Flash Recovery
Areas”
Some more stuff

19. “ Configure the DB_ULTRA_SAFE
initialization parameter on both the
primary and standby systems for the
most comprehensive data corruption
prevention and detection.“
DB_ULTRA_SAFE
11G NEW FUNCTIONALITIES

20. DB_ULTRA_SAFE
In the Primary DB

21. DB_ULTRA_SAFE
In the Standby

22. “Read Only Tables”
“Health Monitor”
“Virtual Columns”
“Edition Based
Redefinition”
purely expression-based
and aren't stored on-disk
Enables you to upgrade the
database component of an
application while it is in use,
thereby minimizing or eliminating
down time.
Other Important Stuff
In Oracle 11G
