Symantec/Veritas and Oracle Together Comparison of Single Instance, HA, and RAC Symantec/Veritas and Oracle Together

Three Levels of Availability for Oracle SINGLE INSTANCE HA /CLUSTERING RAC 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 Recommended Architectures Symantec/Veritas and Oracle Together

Database Fail-over: What to Expect SF HA for Oracle (single instance Oracle) SF CFS HA w/ (single instance Oracle) SF RAC (Oracle RAC) Import disk group Mount file system Start database Resolve transactions (replay logs) Update IP Clients Reconnect Import disk group Mount file system Start database Resolve transactions (replay logs) Update IP Clients Reconnect Import disk group Mount file system Start database Resolve transactions (replay logs) Update IP Clients Reconnect 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. Symantec/Veritas and Oracle Together

So for a 3 database workloads you need to have at least 3 Active and 3 Passive nodes. --CRS does not handle OS and hardware failures Solution3: Non RAC Oracle 9i/10g HA solution in standby mode with SF Oracle HA For planned server or instance outages (a.k.a. "maintenance"), RAC is not the very best HA alternative; Databases: 3 Failover time: seconds Performance Overhead: 15-25% Databases: 3 Failover time: minutes Performance Overhead: 0% Databases: 3 Failover: Seconds to minutes Performance Overhead: 0% Symantec/Veritas and Oracle Together

Symantec/Veritas and Oracle Together Storage Foundation for Oracle HA Detects fault Gracefully shuts down: Application & database Network resources File system & storage resources Migrates storage to standby Starts resources on standby Redirects traffic to standby Can my application be clustered? Application must be crash tolerant Can restart to known point after single server crash All data needed to restart stored on disk Does not require shutdown to come back up properly No need for “cluster aware” applications, simply well behaved applications Most enterprise applications are completely cluster capable!

Symantec/Veritas and Oracle Together Summary Symantec/Veritas and Oracle Together

Summary – SFOR/SFRAC value adds Fully supports enterprise IT standardization – it is a complete solution Fully supports any combination of Oracle single instance and RAC environments. Includes DMP which provides the necessary functionality for load balancing and channel failover of storage resources 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 Offers flexibility and granularity in laying out storage recognizing that dynamically changing environments will need i/o tuning from time to time. Is a mature product (about 12 years old) that is endorsed for all environments including large scale ERP such as SAP. 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. Provides robust (kernel level) cluster member management and performance/availability of cluster interconnect and CVM/CFS 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. 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! Symantec/Veritas and Oracle Together
