Quick I/O

Breakthrough VERITAS File System interface technology

Presents 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 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!

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)
