VxVM Resilvering /Mirror for Oracle (SmartSync for RAW, now CFS)
VXFS Snapshots (For quick, consistent, Oracle backups)
QIO (Quick IO for Asynchronous writes)
Cached QIO ( For satisfying File System read-cache requests)
ODM (Asynchronous writes without File System locking)
CVM (Developed by VERITAS for Oracle Parallel Server 8i)
VOS (VERITAS ORACLE SUN, JEC- Joint Escalation Center)
SFRAC for Solaris, AIX, HP-UX
RMAN (NetBackup)
APM (Indepth for Oracle)
Today: Widespread adoption in Oracle deployments on open systems
Ongoing development & integration (Symantec Engineers onsite at
Oracle’s corporate office)

Recent activities with Oracle
• Platform partner
– Onsite, part of Oracle release process
– On-going certifications of SFRAC for Solaris, HP-UX, AIX
– SFCFS for RAC on LINUX (RH, Suse & Oracle Enterprise Linux)
• Includes coverage of Oracle 11g
• Support for ASM with Storage Foundation
– Includes VCS agent for HA ASM failovers (Oracle single instance)
• Symantec will develop a Storage Foundation plug-in for
Oracle Enterprise Manager – to be available by OOW –
11/14/2007 and FREE!
• Oracle supports VCS control of RAC resources
– Mostly for control of the Database instance, Listener and other
resources should still be under CRS control, but can be under VCS if
customer really wants it that way.

Comparison of
Single Instance,
HA, and RAC
Symantec/Veritas and Oracle Together
23
Three Levels of Availability for Oracle
SINGLE INSTANCE
HA /CLUSTERING
RAC ARCHITECTURES
• Manual fail-over
• Automated fail-over
• Highest availability
• Simple set-up
• Active/passive or N+1
• Shared resources
• Hours to restore
• Minutes for fail-over
• Fastest fail-over
Recommended Architectures

Resolving database transactions (replaying redo logs) to recover failed
transactions during fail-over is a necessary step in any HA architecture. Log
replay is likely to account for the bulk of recovery time.

Storage Foundation for Oracle HA
1. Detects fault
2. Gracefully shuts down:
1. Application & database
2. Network resources
3. File system & storage resources
3. Migrates storage to standby
4. Starts resources on standby
5. Redirects traffic to standby

Comparison of Single Instance HA and RAC
• No matter which Oracle availability approach you
select, Symantec/Veritas has the solution:
– Single Instance HA with non clustered VM/FS
• SFOR-HA with VxVM/VxFS
– Single Instance HA with clustered VM/FS
• SFOR-HA with CVM/CFS
– RAC
• SFRAC
• And just to let you know, regarding Disaster Recover
(DR), we have:
– Global Cluster Option (GCO) – extension of VCS
– Veritas Volume Replicator (VVR)

Summary
Symantec/Veritas and Oracle Together

Summary – SFOR/SFRAC value adds
1. Fully supports enterprise IT standardization – it is a complete solution
2. Fully supports any combination of Oracle single instance and RAC environments.
3. Includes DMP which provides the necessary functionality for load balancing and
channel failover of storage resources
4. Includes intelligent storage management, as it has understanding and visibility of
underlying physical disk in enterprise class storage environments such as Hitachi,
EMC, and IBM Shark
5. Offers flexibility and granularity in laying out storage recognizing that dynamically
changing environments will need i/o tuning from time to time.
6. Is a mature product (about 12 years old) that is endorsed for all environments including
large scale ERP such as SAP.
7. Provides an infra-structure that facilitates DBAs, SAs, and Storage Admins working
effectively and efficiently as a team to provide robust infra-structure for mission critical
environments.
8. Provides robust (kernel level) cluster member management and
performance/availability of cluster interconnect and CVM/CFS
9. Because the SFOR/SFRAC suite of products fully supports single instance Oracle as
well as RAC, if you choose to deploy without RAC or with a mix of single instance and
RAC, the very same infrastructure will meet your needs.
10. With the additional capabilities of VVR and GCO, a Highly Available solution can be
architected for your Oracle environment to address not only HA, but DR as well!
