Oracle Database 10g Release 1Simple Windows install

Commitment to Windows

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

Partnering with Microsoft

Oracle sponsors Microsoft events (PDC 2003, TechEd 2004, 2005)

Oracle operating system process. Normally limited to 3GB of address space. With VLM, Oracle can get up to 64GB of database buffers.

For Kernel 1GB

64-bit

Interoperability between 32-bit clients and 64-bit servers and vice versaImproved performance, availability and scalabilityTimeline

10.1.0.4 available NOW

32-bit to 64-bit upgrade process is simple32-bit data files are compatible with 64-bit DBNo need to recreate the databaseFull export and import not required

Database Upgrade Assistant automates processTransparent migration for end-user applications

No changes required to existing client applications when running against 64-bit database


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 internallyMaximum file size is 64GB

Maximum database size is 4 petabytes


Developed for WindowsIntegration with Performance MonitorIntegration with Event LogIntegrated with Windows Services

10TB database in productionUnlimited scalability on 64-bit

New for Windows Server 2003

Large Page supportFor instances with large memory requirements, large page support can improve performance.

NUMA support for memory/schedulingDatabase intelligently allocates memory and schedules threads based on node configuration

Automatically adapts to workload changes

Maximizes memory utilization

Single Parameter makes it easier to use

Helps eliminate out- of-memory errors

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 iAS (application server) and AD

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/EM64T)

RAC Licensing

RAC is available for 2 Oracle database levelsOracle 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 offeringsRAC in a box (http://www.dell.com/oracle)

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
