Commitment to Windows
  • Oracle7 was the first database to ship on Windows
    in 1994
  • Windows Server is a base development platform for
    Oracle
  • Windows Server is a Tier 1, fully supported
    platform for Oracle
  • Focused Engineering and Product management groups
    for Windows-specific integration projects
  • Supported both 32-bit and 64-bit Windows Server
    2003 on day of O/S release

5
Partnering with Microsoft
  • Oracle sponsors Microsoft events
  • (PDC 2003, TechEd 2004, 2005)
  • Microsoft sponsors Oracle events
  • OracleWorld 2004, UKOUG
  • Communication channels open at various levels in
    the organizations

10
Database Architecture
  • Thread model, not a port of Oracles process
    architecture
  • Oracle.exe, 1 process many threads
  • 3GB (32-bit) or 8TB (64-bit) maximum memory per
    database instance. VLM support allows 3GB on
    32-bit.

12
32-bit VLM Support
Memory from AWE calls used for db buffers only.
The amount of AWE memory allocated equals db_bl
ock_size
times db_block_buffers.
Extended memory available for db buffers via AW
E calls
16GB
Oracle operating system process. Normally
limited to 3GB of address space. With VLM,
Oracle can get up to 64GB of database buffers.

13
64-bit
  • Interoperability between 32-bit clients and
    64-bit servers and vice versa
  • Improved performance, availability and
    scalability
  • Timeline
  • 10.1.0.4 available NOW
  • 32-bit to 64-bit upgrade process is simple
  • 32-bit data files are compatible with 64-bit DB
  • No need to recreate the database
  • Full export and import not required
  • Database Upgrade Assistant automates process
  • Transparent migration for end-user applications
  • No changes required to existing client
    applications when running against 64-bit database

14
Database Architecture
  • File I/O
  • Oracle10g supports asynchronous I/O to all types
    of files
  • Logical and physical raw files and partitions are
    fully supported (faster than NTFS)
  • Full 64-bit file I/O internally
  • Maximum file size is 64GB
  • Maximum database size is 4 petabytes

15
Database Architecture
  • Developed for Windows
  • Integration with Performance Monitor
  • Integration with Event Log
  • Integrated with Windows Services
  • 10TB database in production
  • Unlimited scalability on 64-bit

16
New for Oracle10g
  • User-thread support
  • An extension of the thread support already in
    place since Oracle7.
  • Run the database in user-thread mode, which
    employs Oracle-scheduled user-mode threads (or
    fibers) instead of O/S-scheduled threads.
  • For CPU intensive apps, this will provide a
    performance boost and reduce CPU utilization.

17
New for Windows Server 2003
  • Large Page support
  • For instances with large memory requirements,
    large page support can improve performance.
  • NUMA support for memory/scheduling
  • Database intelligently allocates memory and
    schedules threads based on node configuration

18
Automatic Shared Memory Tuning
  • Automatically adapts to workload changes
  • Maximizes memory utilization
  • Single Parameter makes it easier to use
  • Helps eliminate out- of-memory errors
  • Can help improve performance

Stored Procedure Testing
21
Cross-platform Security Integration (Kerberos)
  • With the Oracle Advanced Security Option,
    cross-platform Kerberos support is enabled
  • A Windows client can connect to a non-Windows
    server securely
  • Integrated with Microsoft Key Distribution Center
    (MSKDC)

22
Active Directory Integration
  • Database registration and name resolution
  • Store and resolve connect descriptors through AD
  • Eliminate tnsnames.ora on clients
  • Centralize configuration, reduce administration
  • Enhanced tools support for storing connect
    descriptors
  • Windows Explorer, AD Users and Computers
  • Oracle DB Configuration Assistant, Net Manager,
    Net Configuration Assistant

23
Database Name Resolution
2 - User specifies AD-stored connect string
4- Connection to database is established
Windows Environment
Oracle 10g
3 - Connect string is resolved from ADS via
Oracle Net
1 Admin uses Oracle Net Manager or DBCA to
populate AD connect string data
Microsoft AD
24
Single Sign-on Support (client/server)
  • Windows Native Authentication adapter provides
  • O/S authentication for database users
  • Database lookup of O/S-enabled roles
  • Authentication done via Kerberos
  • With the purchase of the Advanced Security
    Option, single sign-on can be done over SSL as
    well
  • Integrated with Microsoft Certificate Store (MCS)
    for X.509 certificates

25
Single Sign-on Support (three-tier)
  • Oracles mid-tier Single Sign-On server (SSO) is
    also integrated with Windows and Active
    Directory
  • Allows single sign-on support via Web browser
    credentials
  • Windows Authentication Plug-in allows
    interoperability between Oracle iAS (application
    server) and AD

    its inception
  • Oracle is strongly integrated with the Windows
    Server Platform
  • Oracle is a top performing DBMS on Windows Server

  • Oracle is available on all Windows Server
    implementations (all editions, 32-bit, 64-bit

  • Design for (not all 4)
  • Performance
  • Cost
  • Scalability
  • Availability
  • 99.999 is 5 minutes a year
  • 4 hour
  • 30 seconds - 5 minutes
  • Instant ?

Logical Standby Database
  • Managed as a single configuration
  • Primary and standby databases can be Real
    Application Clusters or single-instance Oracle
  • Up to nine standby databases supported in a
    single configuration

Fast-Start Failover
Standby Site

Observer
  • Data Guard in steady state transmitting redo
  • Observer monitoring state of the configuration

37
Fast-Start Failover
Standby Site
Primary Site
Observer
  • Disaster strikes the primary connections lost

38
Fast-Start Failover
Standby Site
Primary Site
Observer
  • Observer primary connection times out
    (timeout threshold configurable)
  • Observer asks target standby if it is ready to
    fail over
  • Observer begins Fast-Start Failover

39
Fast-Start Failover
Primary Site
Observer
  • Target standby automatically becomes new primary

40
Fast-Start Failover
Standby Site
Primary Site
Observer
  • After old primary is repaired, Observer
    re-establishes connection
  • Observer automatically reinstates old primary to
    be a new standby
  • Redo transmission starts from new primary to new
    standby

41
Clustering
  • Fail Safe
  • provides quick node failover
  • high availability solution
  • integrated with Microsoft Cluster Services
    (MSCS)
  • Real Application Clusters (RAC)
  • shared-disk, clustered database
  • availability, scalability, reliability
  • Oracle-provided clusterware
  • Cluster File System (CFS)
  • Oracle-written file system for shared disks
  • one software image can be shared by nodes

42

  • High Availability for solutions deployed on
    Windows clusters
  • Supports Windows Server 2003 (and Windows 2000
    Server and Windows NT Server) clusters

Real Application Clusters
  • RAC is database clustering
  • Shared disk solution
  • One physical database serviced by multiple
    cluster nodes/instances
  • Cluster consists of database nodes, fast cluster
    interconnect, shared disk subsystem
  • Oracle provides integrated clusterware and
    storage management

RAC Licensing
  • RAC is available for 2 Oracle database levels
  • Oracle Standard Edition
  • RAC is Free with SE ( up to 4 CPUs total - 2
    or 4 nodes)
  • Oracle Enterprise Edition ( up to 100 nodes )
  • Minimum licence for an SE/RAC cluster is
  • 3,000 for a 2 node cluster
  • Oracle Hardware Partners have bundled offerings
  • RAC in a box (http//www.dell.com/oracle)

51
Cluster File System
  • Oracle10g Clustered File System (CFS) on Windows
    for easier manageability
  • Support database files on CFS instead of raw
    partitions, which are much harder to manage
  • Put ORACLE_HOME on CFS, providing better single
    system image
  • Implemented as a Windows file system via
    kernel-mode driver
  • Cluster aware installation through the Oracle
    Universal Installer
