Applies to:

Oracle Server - Enterprise Edition - Version: 10.2.0.1 to 11.2.0.1.0 - Release: 10.2 to 11.2
Microsoft Windows (32-bit)
Microsoft Windows Itanium (64-bit)
Microsoft Windows x64 (64-bit)

Purpose

The goal of the Oracle Real Application Clusters (RAC) Starter Kit is to provide you with the latest information on generic and platform specific best practices for implementing an Oracle RAC cluster. This document is compiled and provided based on Oracle Support's experience with its global RAC customer base.

This Starter Kit is not meant to replace or supplant the Oracle Documentation set, but rather, it is meant as a supplement to the same. It is imperative that the Oracle Documentation be read, understood, and referenced to provide answers to any questions that may not be clearly addressed by this Starter Kit.

All recommendations should be carefully reviewed by your own operations group and should only be implemented if the potential gain as measured against the associated risk warrants implementation. Risk assessments can only be made with a detailed knowledge of the system, application, and business environment.

As every customer environment is unique, the success of any Oracle Database implementation, including implementations of Oracle RAC, is predicated on a successful test environment. It is thus imperative that any recommendations from this Starter Kit are thoroughly tested and validated using a testing environment that is a replica of the target production environment before being implemented in the production environment to ensure that there is no negative impact associated with the recommendations that are made.

Scope and Application

This article is intended for use by all new (and existing) Oracle RAC implementers.

RAC on Windows Highlighted Recommendations

This is a list of the core best practices and references identified by the RAC Assurance Team relevant to Windows specific RAC implementations. The rest of this chapter provides additional best practices and references from our team.

Note that it is now possible to request one-off patches on Windows Platforms. For detailed information, please review the following article: Note:1122596.1 One off Patch process for the RDBMS bundled patch on Microsoft Windows. Please note that one-off requests (on Windows) are always subject to the discretion of our bug diagnostics and escalations support team.
Disable Anti-Virus software running on cluster nodes before and for the entire duration of the installation Oracle 11gR2 on Windows (be mindful of manual reboots during this time). Anti-Virus software may (of course) be re-enabled following the installation.
Please be aware of the following alert for RAC on Windows customers: Note 1051503.1 : RACG Problem with Windows 10204 Patch 28, 29, 30 and 31 Bundles
Do not set ORACLE_HOME as an environment variable in RAC on Windows environments. If needed (for example, when running opatch) set this variable as needed in a command prompt window.
Install the Oracle Process Manager Daemon (OPMD) to manage the proper startup of Oracle clusterware services. OPMD is available with 10.2.0.3 and 10.2.0.4 patchset installations, but you must issue the command: opmd -install on each node. For 10.2.0.4 and 11gR1, OPMD is automatically configured upon clusterware installation. Reference: Note 358156.1
Workload management services created and configured in the OCR do not register properly with the listener if the instance names were entered into the OCR in UPPER CASE. Reference: Note 731287.1
Windows should be optimized for Memory Usage of Programs not System Caching

Start -> Settings -> Control Panel -> System -> Advanced -> Performance -> Memory Usage: Adjust for best performance of -> Programs instead of System Caching

RAC on Windows Best Practices

Tool/Utility

DHCP Media sensing MUST be disabled - This is a requirement outlined in the RAC installation guide for the Windows platform in the section entitled: Network Hardware Requirements. DHCP Media Sensing is disabled by default on Windows 2003. This change must be manually implemented for Windows 2000. Instructions for implementing this change can be found on the Microsoft support website using the following link: http://support.microsoft.com/default.aspx?scid=kb;en-us;239924

Run Perfmon to monitor CPU, Memory, Network, Disk IO Rates - To aid in troubleshooting, configure Perfmon to monitor these OS statistics and to generate binary log files (.BLG). Instructions for implementing this change can be found on the Microsoft support website using the following link: http://support.microsoft.com/kb/146005

Download and implement Debugging Tools for Windows - It is a good best practice to download and install Debugging Tools for Windows (containing, among others, adplus and windbg) on each node of your RAC on Windows cluster in case those tools are needed while troubleshooting. Instructions for implementing this change can be found on the Microsoft support website using the following link: http://www.microsoft.com/whdc/devtools/debugging/default.mspx

Download and familiarize the DBA team with useful Windows utilities (such as those available through the sysinternals website: http://www.sysinternals.com/ for example: Process Explorer) that can assist in troubleshooting.

Set /USEPMTIMER in the boot.ini. Reference Note 437101.1 EXCESSIVE LMS AND LMD TRACE FILE SIZES GENERATED ON WINDOWS RAC

There is a general requirement for Oracle RAC that the time on all the nodes be the same. If the Windows Time Service is being used, it MUST be configured to prevent the time from being adjusted backwards. Perform the following steps to ensure the time is NOT adjusted backwards using Windows Time Service perform the following steps on each cluster node.

Open a command prompt and type “regedit”.
Within the registry editor locate the HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesW32TimeConfig key.
Set the value for MaxNegPhaseCorrection? to 0 and exit the registry editor.
Open a command prompt and execute the following to put the change into effect:

cmd> W32tm /config /update

With 11gR2 time synchronization can be performed by the Clusterware using CTSSD (Cluster Time Synchronization Services Daemon) or by using the Windows Time Service.

Networking Considerations

After installing Windows Server 2003 Service Pack 2 (SP2) or Windows Server 2003 Scalable Networking Pack (SNP), turn off default SNP features. On a computer that has a TCP/IP Offload-enabled network adapter, you may experience many network-related problems like network adapters consuming lots of nonpaged pool memory or adapters requesting large blocks of contiguous memory causing the computer to stop responding when it tries to free the memory. This problem also affects Windows 2008 operating systems. See My Oracle Support Note:988008.1 and Microsoft article: http://support.microsoft.com/kb/948496/en-us for more details.

SQLNET.AUTHENTICATION_SERVICES=(NONE) will prevent CRS resources from starting. If sqlnet.authentication_services (in the sqlnet.ora file) is set to (NONE) instance startup by CRS fails as "USR_ORA_CONNECT_STR=/ as sysdba" is used when CRS starts up resources as Oracle and without NTS this does not work. Ensure SQLNET.AUTHENTICATION_SERVICES=NTS in all Oracle homes to allow sysdba authentication.

Do not use the names: PUBLIC and PRIVATE (all caps) for your public and interconnect networks (NICs) due to unpublished code defect Bug 6844099. The words public and private themselves may be used, for example: Public and Private are acceptable.

Please note that IPv6 addressing is currently not (yet) supported with RAC. For more information, reference: http://stcontent.oracle.com/content/dav/oracle/Users/Users-K/kant.patel/IPv6/OracleDatabase_IPv6_SOD.pdf

Storage Considerations

It is strongly advised to bring the entire Oracle software stack down in order to complete all disk virus scans for conventional Fat 16/32/NTFFS as well as OCFS file systems. This is because Oracle and the virus scan software use different types of locking which are not compatible. Hence a shared disk for the database configured with OCFS could have 2 nodes virus scanning at the same time and could potentially cause the cluster to crash. We strongly suggest that you virus scan only from one node and only during maintenance windows. OCFS disks that only contain Oracle database datafiles do not need to be virus scanned. OCFS disks that contain any non-database datafiles or database configuration files should be scanned periodically (with the entire Oracle stack down).

Memory Considerations

A good rule of thumb for Oracle RAC on Windows environments is to keep memory allocation under 80%. We recommend shooting for 75% allocated, that is, more than 20-25% free. This will allow for ample memory needed for Windows OS operations (including collection of physical memory dumps if required)
