Database Architecture Thread model, not a port of Oracle’s process architecture Oracle. exe, 1 process many threads 3 GB (32 -bit) or 8 TB (64 -bit) maximum memory per database instance. VLM support allows >3 GB on 32 -bit.
32 -bit: VLM Support rest of RAM For O/S, other apps For Kernel 16 GB Windows Server 2003 Memory Limits (32 -bit) Standard Edition: 4 GB Enterprise Edition: 32 GB Datacenter Edition: 64 GB 1 GB SGA 3 GB Code with AWE database threads/ memory
32 -bit: VLM Support rest of RAM Extended memory available for db buffers via AWE calls Memory from AWE calls used for db buffers only. The amount of AWE memory allocated equals db_block_size times db_block_buffers. 16 GB For O/S, other apps For Kernel 1 GB Window on db buffers in AWE SGA mem SGA minus db buffers 3 GB Code Oracle operating system process. Normally limited to 3 GB of address space. With VLM, Oracle can get up to 64 GB of database buffers. with AWE
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
Database Architecture File I/O Oracle 10 g 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 64 GB Maximum database size is 4 petabytes
Database Architecture Developed for Windows Integration with Performance Monitor Integration with Event Log Integrated with Windows Services 10 TB database in production Unlimited scalability on 64 -bit
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
Automatic Shared Memory Tuning Online Users Large Batch Jobs Buffer Cache Automatically adapts to workload changes Buffer Cache Maximizes memory utilization Large Pool Single Parameter makes it easier to use Large Pool SQL Cache Java Pool SGA PGA sort Helps eliminate outof-memory errors Can help improve performance

NET Oracle Explorer Stored Procedure Testing Designers and Wizards Oracle Data Window Automatic Code Generation SQL Query Window PL/SQL Editor Integrated Help System Beta Support for. Net Language Stored Procedures

Cross-platform Security Integration (Kerberos) With the Oracle Advanced Security Option, crossplatform Kerberos support is enabled A Windows client can connect to a non-Windows server securely Integrated with Microsoft Key Distribution Center (MSKDC)
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
Database Name Resolution 2 - User specifies AD-stored connect string 4 - Connection to database is established Windows Environment Oracle 10 g 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
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
Single Sign-on Support (three-tier) Oracle’s 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 i. AS (application server) and AD
User Sign-On to Oracle 1 - User attempts to sign on Oracle 10 g Single Sign-On Windows Environment Oracle Portal Oracle 2 - Oracle Authentication E-Business Suite Release 11 i 4 - Authentication via Windows Plug-in Microsoft Active Directory 3 - User identity confirmed Oracle Internet Directory Delegated Administration Console
Conclusion Oracle has been committed to Windows Server since 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 Itanium, & this year 64 -bit AMD/EM 64 T)

Standby - Data Guard Configuration Standby Site A Primary Site Standby Site B Broker Primary Database Physical Standby Database 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
Oracle Data Guard Architecture Physical Standby Database Sync or Async Redo Shipping Production Database Backup Redo Apply Network Broker Transform Redo to SQL Logical Standby Database SQL Apply Open for Reports Additional Indexes & MVs
Fast-Start Failover Primary Site Standby Site Observer 1. Data Guard in steady state – transmitting redo 2. Observer monitoring state of the configuration
Fast-Start Failover Primary Site Standby Site Observer 1. Disaster strikes the primary – connections lost
Fast-Start Failover Primary Site Standby Site Observer 1. Observer <=> primary connection times out (timeout threshold configurable) 2. Observer asks target standby if it is ready to fail over 3. Observer begins Fast-Start Failover
Fast-Start Failover Primary Site Observer 1. Target standby automatically becomes new primary
Fast-Start Failover Standby Site Primary Site Observer 1. After old primary is repaired, Observer re-establishes connection 2. Observer automatically reinstates old primary to be a new standby 3. Redo transmission starts from new primary to new standby
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
Oracle Fail Safe High Availability for solutions deployed on Windows clusters Supports Windows Server 2003 (and Windows 2000 Server and Windows NT Server) clusters Support for Oracle Database, i. AS, E-Business Suite 11 i, Forms 6 i, and Reports 6 i Provides fast fail over, high availability Supports up to 8 nodes on Windows Server 2003 Integrates with MSCS for resource failover

RAC Licensing RAC is available for 2 Oracle database levels Oracle Standard Edition RAC is Free with SE ( up to 4 CPU’s 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)
Cluster File System Oracle 10 g 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 kernelmode driver Cluster aware installation through the Oracle Universal Installer
