  • Windows
  • Vmware
  • Virtual Machines running OEL 5.1
  • Firefox, SQLDeveloper, SQLPlus
  • 11g DB running DB control

11g Grid Directions
  • Simplicity - Make the grid as easy as a single
    system
  • Expert system for cross-cluster performance
    diagnostics
  • Zero-configuration node management
  • Quality of service management
  • Seamlessly manage resources across middle-tier,
    database, and storage
  • Policy-based performance and workload management

8
11g Value Proposition
  • Easiest to Manage
  • Highest Quality of Service
  • Highest Performance and Scalability
  • Fault Tolerant
  • Most Secure
  • Best Information
  • Lowest Risk of Change

11g Database Console
  • Objective get familiar with the DB Control UI,
    and navigation through the menus
  • Performance tab
  • Data Movement tab
  • Enterprise Manager, Grid Control, DB Console?!?!

12
Advanced Compression
  • Oracle 9i - compresses data only during bulk load
  • Data warehousing
  • Table compression is now viable for all
    applications
  • Compress during random updates
  • Typical compression ratio of 2x to 3x
  • Database directly reads compressed data bypassing
    decompression overhead
  • Strategy - Compress 10 largest tables in a
    database
  • Reduce table data by half, increase CPU usage 5

Flashback Data Archive
  • Flashback Data Archive
  • Easy, practical way to add time dimension to
    your data
  • For change tracking, auditing, compliance,
  • Query data AS OF any time in the past
  • Efficient storage / retrieval of undo data
  • DFA Vs. Other Flashback Tech
  • Historical data can be accessed from any
    specified duration, far and beyond the undo or
    flashback log data.

Total Recall
21
Flashback Data Archive
  • FBDA process
  • Collects and writes the original data to
    flashback data archive
  • Works Asynchronously
  • Default sleeps for 5min (Changes dynamically
    according to traffic)
  • Flashback Data Archive
  • Based on new data dictionary objects
  • Uses Advanced Compression
  • Uses partitioning in its internal scheme
  • Based upon quota retention policy definitions
    for flashback archive
  • The internal history table is a replica of the
    tracked table with addition timestamp column

Make Change Safe - Realistic Testing with
Database Replay
  • Recreate actual production database workload in
    test environment
  • No test development required
  • Replay workload in test with production timing
  • Analyze fix issues before production

Make Change Safe - Online Upgrades
  • Major online upgrade enhancements
  • Online database upgrades for Data Guard Physical
    Standby
  • Physical Standby is Data Guards high performance
    disaster recovery solution
  • uses new Transient Logical Standby feature for
    online upgrades
  • Online database patching
  • for one-off patches including diagnostic patches

28
Make Change Safe Fault Resolution
  • New facilities to speed fault resolution
  • Automatic Fault Diagnostics
  • New facilities to capture and manage relevant
    information for incidents (faults) to speed
    Support processes
  • Support Workbench
  • Repair Advisors
  • Speed analysis of root cause for faults
  • Advise DBAs on repair strategy

29
Transparent Data Encryption
  • Building on transparent column level encryption
    in Oracle Database 10g Release 2
  • Tablespace level encryption
  • For encrypting entire application data
  • Supports foreign keys and range scan
  • LOB encryption
  • Master Key protection in hardware using PKCS 11
  • Integrates with LogMiner, Logical Standby,
    Streams, Datapump

Oracle SecureFilesConsolidated Secure Management
of Data
  • Many applications have both files and relational
    data
  • e.g. Document Management, Medical, CAD, Imaging
  • SecureFiles breaks the performance barrier that
    has kept file data out of databases
  • Similar to LOBs but much faster, and with more
    capabilities
  • Transparent encryption, compression,
    deduplication, etc.
  • Preserves security, reliability, and scalability
    of database
  • Superset of LOB interfaces for easy migration
    from LOBs
  • Benefits
  • Single security model
  • Single view of data
  • Single management of data
  • High performance

Physical Standby with Real-Time Query
Real-time Queries
Concurrent Real-Time Query
Continuous Redo Shipment and Apply
Primary Database
Physical Standby Database
  • Read-only queries on physical standby concurrent
    with redo apply
  • Supports RAC on primary / standby
  • Queries see transactionally consistent results
  • Immediate appeal to the many users of physical
    standby
  • DR with real time query is unique in the industry
    no idle resources
  • Handles all data types, but not as flexible as
    logical standby
