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
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

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
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 kernelmode driver
Cluster aware installation through the Oracle
Universal Installer
