Quick I/O
Breakthrough VERITAS File System interface technologyPresents regular VERITAS File System files to Oracle as raw character devices
• 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 filesEliminates 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 memory-
to-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
Tested configurationincluded:
•Sun UE 10000 (10 CPUs and 6 GB of RAM) •Solaris 7 (64-bit)•DB Edition 2.2 for Oracle•Oracle 8.1.5 (64-bit)•TPC-C scale factor of 200 warehouses
Database Edition 2.2 with Cached Quick I/O delivers up toSix times the performance of UFS using Direct I/O

Storage Checkpoints
Point-in-time image of databaseStorage 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!

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 blocksDatabase Replication Option (available separately)• Storage Checkpoints allow for database
replication to secondary system to offload primary server of maintenance tasks
Storage Rollback
Recover Quickly from Logical Errors On disk point-in-time image of dataOn disk point-in-time image of data Simply write back changed (blue) blocks to previous state
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)
