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 gt3GB on
  32-bit.

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

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

• Oracle DB Configuration Assistant, Net Manager,
  Net Configuration Assistant

23

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

Observer

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

• 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
