2. Agenda Oracle’s Commitment to Windows Database Architecture
Volume Shadow Copy Service
Clustering
Active Directory & Security Integration
Transaction Services
Summary

3. 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

4. Partnering with Microsoft
Active beta site for Windows and Volume Shadow Copy Service (VSS)
Oracle sponsors Microsoft events (PDC 2003, TechEd 2004)
Communication channels open at various levels in the organizations
Joint support contacts for customer escalations
Conference calls, briefings, etc.

Summary

6. Database Architecture
Thread model, not a straight port of Oracle’s process architecture
3GB (32-bit) or 8TB (64-bit) maximum memory per database instance. VLM support allows >3GB on 32-bit.
Runs as a Windows service process
No limits on memory, connections, resources except those imposed by the operating system

7. 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

8. Database Architecture
Integration with Performance Monitor
Integration with Event Log
10TB database in production
Unlimited scalability on 64-bit

9. New for Oracle10g User-thread support
An extension of the thread support already in place since Oracle7. Users may now 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.

10. 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

11. 32-bit: VLM Support rest of Windows Server 2003 RAM

Summary

21. VSS Concepts
Volume Shadow Copy Service – framework to create point-in-time volume containing highly consistent data
Shadow copy - volume at a well defined time
Providers - Create/manage shadow copies
Requestors - Application that invoke VSS services
Writers – Application that participates in creation of shadow copies

23. Benefits Transparent integration with Windows Shadow copy service
Automatic online point-in-time copy of Oracle database using VSS requestor
Supports multiple Oracle databases on one machine
No installation or configuration needed, installed and enabled by default along with the Oracle database

24. Oracle VSS Writer Runs as a Windows service process
Co-ordinates with Oracle database instances and VSS requestor
Automated recovery on restores
Zero administration overhead for Oracle VSS writer

25. Features Integrated with Recovery Manager (RMAN)
Internally, uses RMAN for recovery on restored files from VSS shadow copies
Integrated with Flash Recovery Area
Automatic deletion of archived logs that are shadow copied by VSS framework
Integrated with Windows Event Log - record of VSS operations

26. Volume-based Shadow Copies
Writer defines the list of files to be included and excluded
Oracle database files residing on volume will be in appropriate state suitable for shadow copy
For example, data files on volume being shadow copied will be in hot backup mode
Archived logs and data files must be on different volumes

27. Component-based Shadow Copies
Define component hierarchy to support
Data file recovery
Table space recovery
Database recovery
Control file recovery
Allow restoring files to new location
Files are automatically recovered and available for use at the end of restore

28. Writer Component Hierarchy
DBNAME=<database name>
SPFile
ControlFile
AllTableSpaces
ArchivedLogs
RecoveryArea
Tablespace SYSTEM
Tablespace <name1>
ArchiveDest1
ArchiveDest2
ArchiveDestN
Tablespace <nameN>
Datafile components
[Datafile number=<fno>]

29. Recovery Procedure
Select the component from the shadow copy that contain the files to recover
Restore the component
User can choose to restore a file to new location
Oracle VSS writer automatically recover the files and makes it available for use
If a file is not available, check Windows Event Log to resolve the error

30. More Usage Scenarios…
Use component based Transportable shadow copies to
Offload backup to another server
Create a reporting database
Create a copy of the database for testing or quick restore
