Database Edition for Oracle
Sales Presentation
Market Drivers
Faster access to data
• Are you using file systems or raw disk partitions to
Oracle data?
Continuous availability (24x7) of missioncritical Oracle databases
• How much does downtime cost your business in regard
to lost user productivity, reduced company revenue, poor
customer service?
Easier management of increasing data
• Do your DBAs have to learn how to manage raw disk
partitions to gain database performance?
What are the Database Editions?
Integrated storage management
solutions optimized for specific
application areas

Feature Overview
Quick I/O & Cached quick I/O
• Raw device performance with file system
manageability
• Cached Quick I/O for up to 150% performance
improvement over raw devices
VERITAS Volume Manager & VERITAS File
System
• Online disk & file management
• Stripped / Mirrored arrays
• Java-based Storage Administrator GUI
Feature Overview (cont’d)
Storage Checkpoints
 Block-Level Incremental Backup (w/ NetBackup)
 Storage Rollback for immediate “point-in-time”
recovery from “logical errors”

Server
• Allows parallel updates to database files for increased
throughput
• Takes advantage of kernel async I/O (Solaris’ KAIO)
• Oracle handles locking for data integrity
• Simple scripts convert existing files to Quick I/O and
create new database files as Quick I/O files
Eliminates traditional UNIX file system overhead
Cached Quick I/O Overview
Implemented as a buffered read, direct
write solution
• Retains data reliability advantage of direct write
• Gains read-ahead at the File System and memoryto-memory copy performance advantage
Easy online management to turn Cache
on/off for Quick I/O files
• Like Quick I/O, enabled on a per-file basis
Multiple database instances can co-exist
with selective caching for specific datafiles
Cached Quick I/O Outperforms
UFS on 64-bit Solaris 7
Database Edition 2.2 with Cached Quick I/O delivers up to
Six times the performance of UFS using Direct I/O

VERITAS QuickLog
• Improves VERITAS File System Write
performance by exporting intent log
• Updates intent log in parallel with accessing file
data
• Eliminates the seek time between intent log area
and file system data area
• Transparent to end users
• Minimal system administration setup
• Database Edition/HA provides automated
QuickLog failover

Storage Checkpoints
Point-in-time image of database
Storage Checkpoints maintain changed
data blocks as database is being
updated
• Uses efficient copy-on-write technique
• No post-processing needed to scan for
changed data blocks
• Changed data blocks are stored on disk
• Take only seconds to complete
• Take as many as you like!

As the primary file system is updated, the original data is copied to
the Storage Checkpoint before the new data is written. As the primary
file system continues to change, the Storage Checkpoint accumulates
the original data blocks.
and updated again..

Uses of Storage Checkpoints

Storage Rollback
 Faster database recoverability from on-disk backup
image managed by VxDBA utility
Block-Level Incremental Backup
 NetBackup manages Storage Checkpoints and
extracts only the changed blocks
Database Replication Option (available separately)
• Storage Checkpoints allow for database
replication to secondary system to offload
primary server of maintenance tasks

Block-Level Incremental Backup
Back up only changed data blocks
• Virtually eliminates backup windows
• Allows more frequent backup schedules
Enhanced performance
• Significantly lowers CPU and network resource
drain during backups
• Faster recovery from backups (vs. applying
changes in logs)
