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


24

Three Levels of Availability for Oracle

RAC ARCHITECTURES HA /CLUSTERINGSINGLE INSTANCE

Recommended Architectures

• Manual fail-over

• Simple set-up

• Hours to restore

• Automated fail-over

• Active/passive or N+1

• Minutes for fail-over

• Highest availability

• Shared resources

• Fastest fail-over


25

Database Fail-over: What to Expect

SF RAC(Oracle RAC)

SF CFS HA w/(single instance

Oracle)

SF HA for Oracle (single instance

Oracle)

• Import disk group

• Mount file system

• Start database

• Resolve transactions (replay logs)

• Update IP

• Clients Reconnect



• Start database


• Update IP




• Start database


• Update IP


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

Single Instance Single Instance

SF HA SF 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


28

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


35

Summary – SFOR/SFRAC value adds

1. Fully supports enterprise IT standardization – it is a complete solution2. 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 resources4. 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!
