Overview

This document applies to Oracle Database 11g R2 running on Red Hat Enterprise Linux 6.x AS x86_64 or Oracle Enterprise Linux 6.x AS x86_64.

Software and Hardware Requirements


Hardware Requirements
  • Oracle requires 1.5 gigabytes (GB) of physical memory.
  • Swap space must be equal to the amount of RAM allocated to the system.
  • Oracle's temporary space (/tmp) must be at least 1 GB in size.
  • A monitor that supports resolution of 1024 x 768 to correctly display the Oracle Universal Installer (OUI)
  • For Dell supported hardware configurations, see the Software Deliverable List (SDL) for each Dell Validated Component at dell.com/oracle.
The following table describes the disk space required for an Oracle installation:

Table 1 : Minimum Disk Space Requirement

Network Requirements
  • It is recommended that you ensure at least one network interface cards for public network.
  • The hostname must follow the RFC 952 standard (www.ietf.org/rfc/rfc952.txt). Hostnames that include an underscore ("_") are not permitted
Operating System Requirements
  • Red Hat Enterprise Linux 6.x AS x86_64
  • Oracle Linux 6.x AS x86_64

Preparing for Oracle Intallation

Attaching to RHN/ULN Repository

NOTE: The documentation provided below discusses how to setup a local yum repository using your operating system installation media. If you would like to connect to the RHN/ULN channels, see the appropriate documentation. For Red Hat see, redhat.com/red_hat_network. For information relating to ULN network see, linux.oracle.com.
This section discusses hosting the repository files from a local filesystem storage. While other options to host repository files exist, they are outside of the scope of this document. It is highly recommended to use local filesystem storage for speed and simplicity of maintenance.
  1. One of the requirements is to have the DVD image mounted either by physical media or by ISO image.
    • To mount the DVD, insert the DVD into the server and it should auto-mount into the /media directory.
    • To mount an ISO image we will need to run the following command as root, substituting the path name of your ISO image for the field myISO.iso:
      mkdir /media/myISO
      mount -o loop myISO.iso /media/myISO
  2. To install and configure the http daemon, configure the machine that will host the repository for all other machines to use the DVD image locally. Create the file /etc/yum.repos.d/local.repo and enter the following:
[local]
name=Local Repository
baseurl=file:///media/myISO/Server
gpgcheck=0
enabled=0

Installing the Dell Validated RPM

Once the Database node is attached to the appropriate yum repository, we will need to install the Dell Validated RPM package. The Dell Validated RPM package automates certain pieces of the installation process required for the installation of Oracle.

The process to install the Dell Validated RPM package is as follows:
  • Download the latest Dell Oracle Deployment tar file from
    http://downloads.dell.com/solutions/enterprise-solution-resources/deployment_guide_rhel6.pdf
    NOTE: The filename will follow the convention: Dell-Oracle-Deployment-OS-version-year-month.tar, for example: Dell-Oracle-Deployment-Lin-EL6-2012-08.tar
  • Copy the Dell Oracle Deployment tar file to a working directory of all your cluster nodes.
  • To go to your working directory, enter the following command:
    # cd </working/directory/path>
  • Untar the Dell-Oracle-Deployment release using the command:
  • # tar zxvf Dell-Oracle-Deployment-o-v-y-m.tar.gz
NOTE: Where, o is the operating system, v is the operating system version, y is the year, and m is the month of the tar release.
  • Change directory to Dell-Oracle-Deployment-o-v-y-m
  • Install the Dell-Oracle-RDBMS-Server-11gR2-Preinstall RPM package on all your cluster nodes using the following command:
    # yum localinstall dell-oracle-rdbms-server-11gR2-preinstall* --nogpgcheck

Installing the Dell Oracle Utilities RPM

The Dell Oracle utilities RPM is designed to do the following Dell and Oracle recommended settings:
  • Create Grid Infrastructure directories, set ownership, and permissions.
  • Create grid user.
  • Create Oracle Database (RDBMS) directories, set ownership, and permissions.
  • Create the Oracle base directories, set ownership, and permissions.
  • Set pam limits within (/etc/pam.d/login).
  • Setup /etc/profile.
  • Set SELinux to Disabled.
  • Install the Dell PowerEdge system component drivers if applicable.
  • Set kernel parameters.
  • Set nproc for grid user within (/etc/security/limits.conf)
The process to install the Dell Oracle utilities RPM is as follows:
  1. Install the Dell oracle utilities RPM package from the Dell-Oracle-Deployment=0-y-m directory the by typing:
    # yum localinstall dell-oracle-utilities* --nogpgcheck
  2. Once the rpm is installed, run the dodeploy script to setup the environment as follows: # dodeploy -g -r 11gR2

    For more information about the Dell oracle utilities RPM and its options, check the man pages using the command: # man 8 dodeploy
NOTE: The Dell-Oracle-Deplyoment tar contains the latest supported drivers provided from our Software Deliverable List (SDL). Consult the README file found within the Dell-Oracle-Deployment tar for installation instructions of the latest drivers.


Oracle Software Binary Location

The Oracle software binaries should be located on the database node. It is important to note that starting with Oracle 11g R2 (11.2.0.3), Oracle Database patch sets are full installation of the Oracle software. For more information on how this impacts future Oracle deployments, see My Oracle Support note: 1189783.1 Important Changes to Oracle Database Patch Sets Starting with 11.2.0.2.

Setting up the Network - Public Network

NOTE: Ensure that the public IP address is a valid and routable IP address.

To configure the public network :

  1. Log in as root.
  2. Edit the network device file /etc/sysconfig/network-scripts/ifcfg-eth#
    where # is the number of the network device:
    NOTE: Ensure that the Gateway address is configured for the public network interface. If the Gateway address is not configured, the Oracle Grid installation may fail.

    DEVICE=eth0

    ONBOOT=yes
    IPADDR=<Public IP Address>
    NETMASK=<Subnet mask>
    BOOTPROTO=static
    HWADDR=<MAC Address>
    SLAVE=no
    GATEWAY=<Gateway Address>
  3. Edit the /etc/sysconfig/network file, and, if necessary, replace localhost.localdomain with the qualified public node name. For example, the command for node :hostname=node.domain.com
  4. Type service network restart to restart the network service.
  5. Type ifconfig to verify that the IP addresses are set correctly.
  6. To check your network configuration, ping the public IP address from a client on the LAN.

Preparing Shared Storage for Oracle Installation

NOTE: In this section, the terms disk(s), volume(s), virtual disk(s), LUN(s) mean the same and are used interchangeably, unless specified otherwise. Similarly, the terms Stripe Element Size and Segment Size both can be used interchangeably.

Oracle Standalone using Oracle ASM requires LUNs for storing Oracle Database files, and Flash Recovery Area (FRA). To ensure high availability it is recommended that you have:

  • At least two shared disks to store your database. Each shared disk should be the same disk speed and size.
  • At least two shared volumes/LUNs or volumes to store your FRA. Ideally, the FRA space should be large enough to copy all of your Oracle datafiles and incremental backups. For more information on optimally sizing your FRA, see My Oracle Support ID 305648.1 section "What should be the size of Flash Recovery Area?"
NOTE: The use of device mapper multipath is recommended for optimal performance and persistent name binding.
NOTE: For more information on attaching shared LUNs/volumes, see the Wiki documentation found at: http://en.community.dell.com/dell-groups/enterprise_solutions/w/oracle_solutions/3-storage.aspx


Partitioning the Shared Disk

This section describes how to use Linux’s native partition utility fdisk to create a single partition on a volume/virtual disk that spans the entire disk.

To use the fdisk utility to create a partition:
  • At the command prompt, type one of the following:
    • #> fdisk –cu /dev/<block_device>
    • #> fdisk –cu /dev/mapper/<multipath_disk>
Where, <block_device> is the name of the block device that you are
creating a partition on. For example, if the block device is /dev/sdb, type: fdisk –cu /dev/sdb

Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0x89058e03.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
The device presents a logical sector size that is smaller than
the physical sector size. Aligning to a physical sector (or optimal
I/O) size boundary is recommended, or performance may be impacted.
  • Command (m for help): n # To create a new partition
  • Command actione extendedp primary partition (1-4):
  • P # To create a primary partition
  • Partition number (1-4): 1
  • First sector (4096-xxxxxx, default 4096):
  • Repeat step 1 for all the disks.
  • Type the following to re-read the partition table and to be able to see the newly created partition(s)
#> partprobe
Or
#> service multipathd restart
Or
#> kpartx –a /dev/mapper/<multipath_disk>
  • Reboot the system if your newly created partition is not displayed properly.

Setting up Permissions for ASM disks using udev rules

Red Hat Enterprise Linux 6/Oracle Linux 6 have the ability to use udev rules to ensure that the system properly manages permissions of device nodes. In this case, we are referring to properly setting permissions for our LUNs/volumes discovered by the OS. It is important to note that udev rules are executed in enumerated order. When creating udev rules for setting permissions, please include the prefix 20- and append .rules to the end of the filename. An example file name is 20-dell_oracle.rules

In order to set udev rules, one must capture the WWIDs of each disk to be used within your ASM device using the scsi_id command.

The command is as follows:

scsi_id --page=0x83 --whitelisted --device=/dev/sdX

where sdX is the name of your block device.

If one must run this command to capture multiple WWIDs, one could use the following for loop to do just that via the shell:

[root@rhel6 ~]# for i in sdb sdc sdd sde; do \ printf "%s %s\n" "$i" \ "$(scsi_id --page=0x83 --whitelisted --device=/dev/$i)"; done

Output:

sdb 360026b900061855e000008a54ea5356a
sdc 360026b9000618571000008b54ea5360b
sdd 360026b900061855e000008a54ea5356a
sde 360026b9000618571000008b54ea5360b

Once the WWIDs have been captured, create a file within the /etc/udev/rules.d/ directory and name it 20-dell_oracle.rules. A separate KERNEL entry must exist for each storage device and will require adding the WWID to the "RESULT==" field.

An example of what needs to be placed in the /etc/udev/rules.d/20-dell_oracle.rules file

#------------------------ start udev rule contents ------------------#

KERNEL=="dm-*", PROGRAM="scsi_id --page=0x83 --whitelisted --device=/dev/%k",RESULT=="360026b9000618571000008b54ea5360b", OWNER:="grid", GROUP:="asmadmin"

KERNEL=="dm-*", PROGRAM="scsi_id --page=0x83 --whitelisted --device=/dev/%k",RESULT=="360026b900061855e000008a54ea5356a", OWNER:="grid", GROUP:="asmadmin"

#-------------------------- end udev rule contents ------------------#

As you can see from the above, the KERNEL command looks at all dm devices, executes the PROGRAM which captures the WWID, if the RESULT of the WWID is matched, appropriately assign the grid user as the OWNER and the asmadmin group as the GROUP.
