Selling the Database Edition for Oracle on HP-UX
November 2000
The NeedKey Customer Concerns
Continuous availability (24x7) of mission-critical Oracle databases• How much does downtime cost your business in regard
to lost user productivity, reduced company revenue, poor customer service?
Faster access to data• Are you using file systems or raw disk partitions to
Oracle data?
Easier management of increasing data• Do your DBAs have to learn how to manage raw disk
partitions to gain database performance?
Building the Solution
What is the customer using, and how does this product fit into their installation?• HP-UX 11.0
– New Installations
– Upgrading OS
• Oracle7.3 or later (inclusive of Oracle8i)– Upgrading database or
– Database can withstand some downtime

manageability• Up to 200% performance improvement over
traditional buffered file system• Cached Quick I/O not available
Protection from disk failures with fault-tolerant storage options
Online administration of database storage
Feature Overview
Storage Checkpoints• Enables Block-Level Incremental Backup• Enables Storage Rollback for immediate
“point-in-time” recovery from on-disk images
VxDBA utility
• Manages Storage Checkpoints and Storage Rollback and monitors file system space
Java-based Storage Administrator GUI• Visual configuration from a single console

Key Differentiator:VERITAS Storage Checkpoints
Point-in-time snapshot 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
Uses of Storage Checkpoints
Storage Rollback: • VxDBA utility manages Storage
Checkpoints for faster database recoverability from on-disk backup image
• Protects from logical errors• What-if analysis
Block-Level Incremental Backup: • NetBackup manages Storage Checkpoints
and extracts only the changed blocks• Virtually eliminates database backup
window
Storage Rollback
Storage Checkpoints are on-disk backup images• Consistent, stable images of a file system at a
particular point in time
Storage Rollback is “restore” from the on-disk backup images or Storage Checkpoints• Copies before-images of data blocks back to the
live file system• Restores without going to tapes
Storage Rollback
Rollback from Storage Checkpoints=
Simply write back changed (blue) blocks to previous state and then apply redo logs to bring database to desired point in time

Database Edition:Block-Level Incremental BackupsBack up only changed data blocks!
Higher data availability• Virtually eliminates backup windows• Allows more frequent backup schedulesBackups contain up-to-date data
Enhanced performance• Significantly lowers CPU and network
resource drain during backups• Faster recovery from backups (less redo logs
to apply)
Requires NetBackup Server engine and database server to be a NetBackup client
VERITAS Storage Administrator
Visual configuration management and performance analysis
• Allows one-step graphical execution of common configuration management steps
