This document outlines how to run Storage Foundation HA for Oracle Standalone on a single node Oracleenvironment in lieu of Storage Foundation for Oracle (Database Edition)

A user can modify the configuration of the standard Storage Foundation HA for Oracle Standalone to run in asingle node/single instance standard Oracle non-RAC environment.

Background:VERITAS does not support Storage Foundation for Oracle RAC on a Linux platform due to Oracles lack ofsupport on Oracle RAC for implementations using third party clustering solutions. This guide is intended toenable functionalities like ODM, using Storage Foundation HA for Oracle Standalone in a single instance/singlenode Oracle instance environment to be supported by both Oracle and VERITAS for their respective pieces.

What features are available with Storage Foundation for Oracle (Database Edition) thatare not available with Storage Foundation HA for Oracle Standalone?This configuration supporting single instance/single node Oracle RAC does not support the following featuresets

Storage checkpoints Storage mapping

Storage rollback

Flashsnap

Quick I/O

Concurrent I/O

Flashsnap agent for Symmetrix

File System range locking

What services are provided by Storage Foundation HA for Oracle Standalone?This configuration provides File System, Volume Management, and Oracle Data Management support, similar toStorage Foundation for Oracle, but with a limited feature set. In addition, this configuration will support thefollowing features

Boot Drive Management

External Drive Management

Dynamic Multipathing (DMP)

Storage Provisioning Templates

Storage Expert

Configuration Backup and Restore

Online Administration

(64-Bit) File System

History Log

Named Data Streams

Extent based Allocation

Intent Log Resize File Change Log (4.1 only)

Online LUN Resizing

Portable Data Containers (PDC)

SANPoint Control QuickStart

Hardware Assisted E-Copy

RAID Administration

Quality of Storage Service (QoSS)

Database Encapsulation

Support for Oracle 10g Oracle Table Spaces

Oracle Disk Manager (ODM)

SF/HA for single instance can be configured in two ways:1. Cluster installation. Oracle database will run on one node at a time and can be fast failed over to anothernode in case of a failure.

2. Single node installation. Oracle is only running on single node. No Failover will be provided.The following table describes which modules are configured in both cases:

Module Cluster install Single node install

CVM Yes No

CFS Yes No

VCS Yes No

Vxfen Yes No

IPC Yes No

LMX Yes NoOracle Agent Yes No

ODM Yes Yes

GAB Yes No

LLT Yes No

How do the Oracles OCFS services impact this configuration?Oracle OCFS services are not supported in this configuration.

How are the Oracle CRS services impacted by this?Oracle CRS services are not required for single instance configurations, even in an HA environment. CRS

services are required for multiple instance Oracle 10G RAC configurations.

How is ODM impacted by this configuration?The Oracle Disk Manager (ODM) is an API created by Oracle to provide various I/O possibilities for the database.With Storage Foundation for Oracle (Database Edition), VERITAS provides an "ODM Compliant" cluster filesystem and an ODM Library that is linked into Oracle Database Services. Creating an ODM compliant version ofVERITAS File System gave VERITAS the ability to leverage the exceptional performance of Quick I/O (QIO) andalso add additional management features to better support the database administrator. ODM provides directaccess for the database to the underlying storage without passing through the actual file system interface. Thismeans the database sees performance equivalent to using raw devices, while the administrator sees the storageas easy to manage file systems. The intent of this configuration is to leverage the use of ODM within the StorageFoundation for Oracle RAC, but on a single instance/single node. Another key element for this configurationallows for the removal of VERITAS Cluster Server, however, if High Availability failover is desired, it may be left

in. ODM services can also be supported in the HA configuration.

How do I implement this sort of configuration?To implement the Storage Foundations HA for Oracle Standalone in a single instance configuration,

you will need the Storage Foundations for Oracle RAC (SFRAC) installation CD, Oracle RACinstallation CD, and the Red Hat Enterprise Linux Release 4 Update 1 distribution CDs. You should

also refer to the SFORAC 4.1 Hardware Compatibility List (HCL) which can be found athttp://support.veritas.com to verify supported hardware configurations.

How do I license this sort of configuration?Storage Foundation HA for Oracle Standalone is a specific product that addresses a specific deploymentenvironment. To ensure that you run in a supported configuration you need to follow the guidelines set forth in

this document. Please contact your sales person or VERITAS Customer Care for licensing. You should receive license that reflects one of the following skusA18274H-000000 Storage Foundation HA for Oracle Standalone,Linux,per CPU,v4.1,LicenseW18274H-000112 Storage Foundation HA for Oracle Standalone,Linux,per CPU,v4.1 Basic Support, 1 Yr Regional Business Hours

Two types of installations are possible:

1) Installation procedure for a clustered (HA) configuration:

Storage Foundation HA for Oracle Standalone assumes you are implementing the database environment withhigh availability failover.Installing SF/HA for Oracle Standalone------------------------------------------1. Follow install procedure for SFRAC from SFRAC install guide chapters 2 and 3.Note that I/O fencing must be configured with UseFence=SCSI3 attribute in main.cf configuration file for VERITASCluster Server.2. Create system user and group ids as required by Oracle.

3. Create diskgroup, volume and file system mount for Oracle data files. This can either be a shared mount on ashared diskgroup or a private mount on a private diskgroup. Configure necessary VCS resources for thediskgroup and file system mount. Refer to sample configurations in /etc/VRTSvcs/conf/sample_rac and/etc/VRTSvcs/conf/sample_oracle directories.4. Install single instance Oracle database binaries on each node using Oracle installer. A new database can becreated using dbca from one of the nodes.5. Configure Oracle resource for the database instance in a *failover* service group. Note that Oracle instanceshould only be running on one cluster node at a time.!!!Starting an Oracle instance on two or more nodes simultaneously will result in data corruption!!!6. Copy ODM library.

2) Installation procedure for a single node

Storage Foundation HA for Oracle Standalone assumes you are implementing the database environment with outhigh availability failover. If this will be a single node environment (no high availability - VCS), follow theinstallation instructions as documented in Storage Foundation for Oracle RAC Installation and ConfigurationGuide, chapter 2 and 3 with the following changes:
