Chapter 1
Deploying Oracle 11g on AIX 6.1 with IBM DS3400, DS4000 Series, or DS5000 Series Storage Subsystems
Oracle Real Application Clusters (Oracle RAC) supports the deployment of a single database across a cluster of servers, providing excellent fault tolerance, performance, high availability, and scalability. Oracle RACs are growing in importance in a wide range of customer implementations across all industries for transaction processing and data warehousing applications.

This document provides an overview and some tips and techniques in deploying the Oracle RAC 11g Release 1 database with Oracle RAC on the IBM® AIX® operating system using IBM storage subsystems. The database storage is administered using the Oracle Automatic Storage Management (Oracle ASM) feature.

This document summarizes the procedure of creating a simple configuration using a two-node cluster to illustrate the principles of performing this type of implementation. Actual implementations vary in complexity and require significant expertise in all of the technologies involved.

This document is intended to show any deviations from the Oracle installation guide and any enhancements in implementation because of using the DS4800 storage subsystem. This document does not provide a comprehensive reference for installing all of these components. For full implementation instructions, refer to the product documentation for the hardware being used, for the AIX operating system, for the Oracle Database, and for Oracle Clusterware.

Benefits of Oracle RAC 11g Release 1 Database. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Before you install Oracle Database 11g, you must know how to best configure the storage subsystem for enhanced performance. For this information, refer to Best Practices for Running Oracle RAC Databases with ASM on IBM DS4800 Storage Subsystems. Go to:

http://www-03.ibm.com/support/techdocs/atsmastr.nsf/WebIndex/WP101294

Benefits of Oracle RAC 11g Release 1 DatabaseThe reference configuration shows you how to configure these products to work together to achieve numerous benefits. The reference configuration uses Oracle ASM to manage the Oracle RAC 11g Release 1 database storage running under Oracle Clusterware on AIX with an IBM DS4800 1 storage subsystem. The IBM DS4800 storage subsystem is a robust, high-performance storage subsystem that provides a scalable, flexible, and expandable storage foundation upon which to build a highly reliable database system using Oracle RAC.

Oracle RAC offers these benefits:

• High availability – Provides enhanced uptime for database applications.

• Scalability – Expands capacity by adding servers to the cluster.

• Lower computing costs – Uses lower-cost hardware and reduces expenses associated with application downtime.

• Excellent performance – Spreads the database load across multiple cluster members, which lets performance scale with the size of the cluster.

The IBM DS3400™, DS4000™, and DS5000™ storage subsystems offer these benefits, which go hand-in-hand with those of Oracle RAC:

• High availability – The storage subsystem’s fully redundant hardware and redundant array of independent disks (RAID) functionality makes sure that the storage is as available as the RAC database.

• Scalability – You can add additional storage capacity to the storage subsystem while the storage subsystem continues operation.

• Lower costs – Shared storage within a storage area network (SAN) provides reduced cost compared to storage that is local to individual hosts and reduces management expenses associated with administering the storage.

• Excellent performance – The IBM DS3400, DS4000, and DS5000 storage subsystems are among some of the best performing storage subsystems in their class. Their full front-to-back 4-Gb Fibre Channel2 interface architecture provides bandwidth for the most demanding applications.

1.Solution also works with DS3400, DS5000, and other DS4000 models.2.DS3400 has a Fibre Channel host interface with a SAS disk drive interface.

. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Example Configuration

The DS4000 Storage Manager software package configures and manages the fully redundant hardware and high performance architecture with ease. This application provides management in-band from servers to attached storage, or remotely through the ethernet. The storage subsystems offer several premium features that add functionality when used in a database environment. Storage Partitioning feature and the Enhanced Remote Mirroring feature are two of the important features available.

The Storage Partitioning Premium Feature lets you distribute logical drives on the storage subsystem to different hosts in your SAN, associating each logical drive with one particular host or a group of hosts. The logical drives are presented to each host according to the host type for the different operating systems that are running on those hosts. The Storage Partitioning premium feature provides great flexibility in the use of the storage subsystem for storage consolidation.

The Enhanced Remote Mirroring premium feature provides the ability to mirror logical drives between two IBM storage subsystems. This premium feature provides an additional redundant copy of the data that you can use for rapid disaster recovery. You also can use this premium feature to create a copy of live data for test purposes.

Although these premium features are not used in the simple example configuration shown in this document, many opportunities exist to use these premium features in a real-world Oracle implementation. For more information, discuss these premium features with IBM.

Example ConfigurationThe example configuration contains the following equipment:

• 2 IBM with IBM eServer™ pSeries® 630 servers

• AIX 6.1, Technology Level 1, Service Pack 2

• IBM DS4800 storage subsystem

• Oracle Clusterware (CRS) 11.1

• Oracle Database 11.1.0.6.0

The systems are configured as a two-node RAC cluster. ASM is employed to simplify storage management. The AIX MPIO multi-pathing driver was used to provide failover support.

Configuring the HostsYou must configure hosts to function correctly with Oracle RAC. The following steps describe, in general terms, how to prepare the systems for the Oracle installation.

IMPORTANT Refer to Metalink Bulletin 282036.1, Minimum Software Versions and Patches Required to Support Oracle Products on IBM pSeries, for the latest requirements. This bulletin is available to Metalink users at:https://metalink.oracle.com/. Metalink Bulletin 282036.1 is regularly updated, and the information that the bulletin contains supersedes any information found in this paper.

1 Install the AIX operating system if AIX is not already installed.

The example configuration uses AIX 6.1 Level 1.

2 Install additional software packages required for Oracle.

■ bos.adt.base

■ bos.adt.lib

■ bos.adt.libm

■ bos.perf.libperfstat

■ bos.perf.perfstat

■ bos.perf.proctools

■ rsct.basic.rte

■ rsct.compat.clients.rte

■ xlC.aix61.rte:9.0.0.1 (See the previous important note)

■ xlC.rte:9.0.0.1 (See the previous important note)

3 Download and install the updates to the AIX operating system from IBM's website:

http://www-933.ibm.com/support/fixcentral/

The example configuration uses AIX 6.1 Level 1.

4 Configure the network interfaces of the host.

The example configuration requires at least two ethernet interfaces:

■ One for the Oracle public network

■ One for the private network used by Oracle Clusterware


https://metalink.oracle.com/CSP/ui/index.html

http://www14.software.ibm.com/webapp/set2/sas/f/genunix3/aixfixes.html

http://www14.software.ibm.com/webapp/set2/sas/f/genunix3/aixfixes.html

Configuring the Hosts . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Oracle recommends that you put the private interface on a separate network isolated from all other traffic. Use a separate gigabit ethernet switch for the private network.

Consider using additional interfaces for most deployments to provide more flexibility in configuration and higher performance. In the example configuration, the VIP network shares the interface used for the public network. This network is configured later in the installation process using the Vipca utility. Entries for the internet protocol (IP) address, and the public and private networks, are inserted into the /etc/hosts file.

5 Create users and groups.

a Create two groups, dba and oinstall.

b Add a user, Oracle, with the oinstall primary group and with the dba group.

NOTE Make sure that the user ID for the Oracle user and the group numbers for the dba group and the oinstall group are consistent on all nodes.

6 Set the shell soft limits for the Oracle and root users using the smit chuser command.

■ Soft FILE size = -1

■ Soft CPU time = -1

■ Soft DATA segment = -1

■ Soft STACK size = -1

7 Use the smit chgsys command to set the maximum number of processes for each user to at least 2048.

8 Use the /usr/sbin/no -a command to examine the minimum values for the following network tuning parameters.

ipqmaxlen = 512rfc1323 = 1sb_max = 1310720 (2*655360)tcp_recvspace = 65536 tcp_sendspace = 65536 udp_recvspace = 655360 (10 * udp_sendspace, must be less than sb_max)udp_sendspace = 65536

NOTE If you modify these parameters, the method depends on whether the system is in compatibility mode. For specific instructions, refer to the AIX documentation for the no command. If you change the value of the ipqmaxlen parameter, you must restart the system for the change to take effect.

9 Download and install the Open Secure Shell (SSH) package from the IBM web site.

http://www.ibm.com/developerworks/eserver/articles/openssh_updated.html

NOTE OpenSSH also requires OpenSSL, which you can download from the IBM website. This software is cryptographic software and the website requires that you log on to download this type of package.

The example configuration uses OpenSSH. The SSH utility is not required for Oracle to function, however this utility is recommended because the SSH utility provides a more secure method of communication between nodes than does rsh. If SSH is available, Oracle uses SSH. Otherwise, Oracle uses rsh. Configuration of rsh user equivalence is not described in this document.

10 Configure SSH for root login permission.

a Locate the sshd_config (/etc/ssh/sshd_config) file.

b Change the sshd_config file to change PermitRootLogin to yes.

c Use the startsrc -s sshd command to start sshd.

11 Configure SSH for user equivalents for root and oracle on all nodes.

a Log on as root.

b Use these commands to generate the SSH key.

cd ~/.ssh

ssh-keygen -t dsa

cat id_dsa.pub >> authorized_keys

c Copy the authorized_keys file to ~/.ssh file on the next system.

d Repeat step b and step c on each system.

e When all systems have a public key in the file, copy the file back to all of the previous systems so that they all have an identical file.

f Test the SSH function from each system to itself and to each of the other systems by issuing the ssh host1 date command. Make sure that the function completes without using a password.

g Log on as the oracle user and repeat step 11so that Oracle also can perform remote commands without passwords.

NOTE The permissions on both the base user directory and the .ssh directory must restrict write access. If the permissions are not correctly set, OpenSSH refuses to provide access without a password, even if the appropriate public key is in the authorized_keys file.

12 Change the .profile file in the Oracle user’s home directory to set the Oracle user's parameters.

13 Change the .profile file in the root user’s home directory to set the Oracle user's parameters.

Add this entry to the .profile file:

AIXTHREAD_SCOPE=S

14 Synchronize the system time between the hosts in the cluster using any effective method. If an Network Time Protocol (NTP) server is available, use this method to set up xntpd.

a Change the /etc/ntp.conf file to add or change the name or IP address of the NTP servers.

Table 1–1 Oracle User’s Parameters

Parameter to Add Description

umask 022

AIXTHREAD_SCOPE=S An environment variable that directs the system to place user threads within a system-wide scope rather than a process-wide contention scope. This placement provides better performance and more efficientmemory use.

CRS_HOME A unique home directory for Oracle CRS binaries.

ASM_HOME Use this parameter if you want to install separate Oracle binaries for Oracle ASM. This method is preferred if more than one database instance is supported by Oracle ASM.

ORACLE_HOME A unique home for the database binaries.

LD_LIBRARY_PATH The complete pathway is $ORACLE_HOME/lib.

ORACLE_BASE Identifies the Oracle base directory.

ORACLE_SID Identifies the instance.

PATH Include $ORACLE_HOME/bin.

CLASSPATH Include $ORACLE_HOME/jdbc/lib/

<classes files>.

b Add a line server <hostname> for each host.

c Start the service using the smit xntpd command.

The example configuration uses NTP to automatically perform this function.

15 Because some Oracle utilities expect lsattr in the /etc directory and cannot function correctly without a link to lsattr, use the ln -s /usr/sbin/lsattr /etc/lsattr command to add a soft link.

Configuring the IBM Storage Subsystems

IMPORTANT You must know how best to configure the storage for enhanced performance. For this information, refer to Best Practices for Running Oracle RAC Database with ASM on an IBM DS4800 Storage Subsystem. Go to: http://www-03.ibm.com/support/techdocs/atsmastr.nsf/WebIndex/WP101294.

Use the DS4000 Storage Manager application and various AIX system utilities to configure the IBM storage subsystem.

1 Use the DS4000 Storage Manager utility to create logical drives on the storage subsystem that you can share for CRS communication and database storage.

NOTE You also might use additional logical drives for Oracle binaries and similar purposes. However, using logical drives local to one particular system requires the Storage Partitioning premium feature.

Analyze your implementation to determine the appropriate logical drive sizes, wanted RAID levels, and other parameters. The reference configuration uses the following minimal configuration of shared logical drives:

■ One Oracle Cluster Registry (OCR) logical drive (300 MB, RAID 1)

■ One Clusterware voting disk drives (300 MB, RAID 1)

■ One logical drive for Oracle ASM's SPFILE (100 MB, RAID 1)

■ Two logical drives for Oracle ASM data storage (300 GB, RAID 5)

The number and the size of the logical drives created for Oracle ASM storage varies based on the individual implementation, but the sizes used for the OCR disk drives, voting disk drives, and the Oracle ASM SPFILE disk drives in the example configuration are sufficient for any configuration.

In the reference configuration, the Oracle binaries are installed on internal disk drives within each individual server. This configuration uses the JFS2 file system and is mounted as /u01.

2 Configure the shared disk drives in the operating system.

■ After you have created the logical drives on the storage subsystem, and mapped to the servers, the cfgmgr command rescans the AIX system for changes to the physical devices.

■ The lspv command shows the physical devices that AIX has configured.

■ The mpio_get_config -Av command displays LUN numbers, disk drive name, and the associated logical drive names configured on the storage subsystem.

3 If the hdisk names for each logical drive on the storage subsystem that the system can share in the cluster are not identical on all cluster nodes, create new device nodes for each of the logical drives to give them a consistent name across all nodes.

For example, if the logical drive for the first OCR disk drive was hdisk2 on node1 and hdisk3 on node2, you can create a new devnode called /dev/ORA_OCR1 on each host. The new devnode uses the major numbers and the minor numbers that correspond with the same logical drive on each system. Show the major numbers and the minor numbers with the mknod /dev/ORA_OCR1 c <major# of OCR> <minor# of OCR> command to create the new devnode.

Even when the disk drive names correlate on all of the nodes, still create these named device nodes for easier location and administration. Named device nodes were created on the reference configuration for all shared logical drives using the convention /dev/ORA_<use>.

4 Set the reserve_policy attribute for each logical drive that you want to use for shared access for OCR logical drives, voting logical drives, and Oracle ASM logical drives.

For an IBM storage subsystem, reserve_policy=no_reserve is the correct value.

This value lets the nodes share the logical drives instead of permitting the first system that accesses the logical drive to reserve the logical drive for exclusive use. Oracle coordinates the access to the shared logical drives.

NOTE You must perform this operation on the hdisk* device name rather than on the named devnode created in step 4.

a Use the lsattr -E -l hdisk? | grep reserve command to check the policy.

b Use the chdev -l hdisk? -a reserve_policy=no_reserve command to change the policy.

c Repeat step a and step b on each cluster node.

5 Set ownership and permissions on devnodes for use by Oracle.

NOTE If you created new devnodes for the shared logical drives, set the ownership and permissions on the new one that you created, not the original hdisk* devnode.

a Use these commands to set the ownership for each OCR device file:

chown root:oinstall /dev/<devnode>

chmod 640 /dev/<devnode>

b Use these commands to set the ownership and the permission on the voting disk drive and database device files:

chown oracle:dba /dev/<devnode>

chmod 660 /dev/<devnode>

c Repeat step a and step b on each cluster node.

NOTE Do not assign a physical volume identifier (PVID) to hdisks for use with Oracle ASM.

Installing OracleHere are the basic steps for installing Oracle:

• Create directories for Oracle.

• Set up the Oracle user’s profile.

• Install Oracle Clusterware.

• Install and configure Oracle ASM.

• Install the Oracle Database.

• Configure the listener names.

• Create and configure a database.

Creating Directories for OracleAlthough you can create directory structures for Oracle files in many different ways, for ease of support, use a standard directory structure based on the Optimal Flexible Architecture (OFA) guidelines published by Oracle. For more information about the OFA Guidelines, see Appendix D of the Oracle Database Installation Guide 11g Release 1 (11.1) for AIX Based Systems (B32076-03). The example configuration is based on the OFA guidelines.

Follow these two important guidelines when creating directories for Oracle:

• You must separate the Oracle Clusterware home directory from the database home directories.

• If more than one database is serviced by Oracle ASM, create a separate home directory for Oracle ASM. An Oracle ASM home directory lets you modify the Oracle release for Oracle ASM while not changing the release of any of the databases on the same server. The directory tree must be owned by oracle.

Setting Up the Oracle User's Profile1 Before you install the Oracle binaries, set up the Oracle user's .profile.

2 Add or modify entries for ORACLE_HOME, ORACLE_BASE, PATH, LD_LIBRARY_PATH, and similar environment variables to reflect the directories where the Oracle binaries are placed during the Oracle Clusterware installation.

Installing Oracle ClusterwareAs you install the Oracle Clusterware, keep the following important points in mind:

• Because of permission requirements for Oracle CRS, do not make the CRS_HOME path a subdirectory of the Oracle base directory. For more information, refer to Appendix E of the Oracle Clusterware Installation Guide.

• At the end of the installation process, run the root.sh script as the root user and run this script on only one node at a time, not concurrently.

Installing and Configuring ASMBecause a single ASM instance can service many database instances, Oracle recommends that you install ASM in its own home directory. Follow the naming convention of the OFA guidelines for the directory path. As you install and configure Oracle ASM, keep the following important points in mind:

• If the Oracle ASM instance was not correctly created by the Oracle Universal Installer Wizard during installation, use the dbca utility to add the instance and to create the disk groups.

• If you want additional disk groups, create them using the dbca utility.

NOTE For more detailed information on configuring ASM for an Oracle database, refer to Oracle Best Practices for Running Oracle RAC Database with ASM on IBM DS4800 or DS5000 Series Storage Subsystems.

Installing an Oracle DatabaseIf you want a separate database home, use the Oracle Universal Installer to install another database home for a database instance. Select Install Database Software Only at the Create Database page.

Configuring Listener NamesIf your RAC environment contains both an Oracle ASM instance and a database instance, supporting only one listener.ora configuration file for the Oracle ASM and database instances is easier. This environment variable lets the DBA maintain one set of tnsnames.ora, sqlnet.ora, and listener.ora files for the entire environment.

Creating and Configuring a DatabaseUse the Database Configuration Assistant (DBCA) to create a database. For more information, refer to the Oracle documentation about using DBCA. As you create the database, keep the following important points in mind:

• Using DBCA provides you with the capability to create the Oracle ASM disk groups if you choose to use Oracle ASM.

• The best way to configure listener names is to create an environment variable TNS_ADMIN and to assign the variable to the $ORACLE_HOME/network/admin directory of the database instance. For example:

export TNS_ADMIN=$ORACLE_HOME/network/admin

• Using the Flash Recovery Area (FRA) option is highly recommended. A Flash Recovery Area permits the setup of a separate area on the disk drive for flashback capability, an area for the archive logs, a second copy of the multiplexed redo log files, and an area for RMAN backups. Make sure that the FRA is correctly setup to handle the performance of the database and that the FRA contains enough space.

■ Space to hold all of the data for the data retention periods that are set by the database

■ Space for the type of backups to use

■ Space for the number of backups to hold
