Installing Oracle RAC 11.2.0.3, OEL 6.3 and Virtualbox 4.2 with GNS

Linux, Virtualbox Installation

Check the following link for Linux/VirtualBox installation details: http://www.oracle-base.com/articles/11g/oracle-db-11gr2-rac-installation-on-oracle-linux-6-using-virtualbox.php

  • Install Virtualbox Guest Additons
  • Install package : # yum install oracle-rdbms-server-11gR2-preinstall
  • Update the installation: : # yum update
  • Install Wireshark:  # yum install wireshark     # yum install wireshark-gnome
  • Install ASMlib
  • Install cluvfy as user grid – download here and extract files under user grid
  • Extract grid software to folder grid and  install rpm from  folder:  grid/rpm 
# cd /media/sf_kits/Oracle/11.2.0.4/grid/rpm
# rpm -iv cvuqdisk-1.0.9-1.rpm
Preparing packages for installation...
Using default group oinstall to install package
cvuqdisk-1.0.9-1
  • Verify the currrent OS status by running : $ ./bin/cluvfy stage -pre crsinst -n grac41

 

Check OS setting

Install X11 applications like xclock
# yum install xorg-x11-apps

Turn off and disable the firewall IPTables and disable SELinux
# service iptables stop
iptables: Flushing firewall rules:                         [  OK  ]
iptables: Setting chains to policy ACCEPT: filter          [  OK  ]
iptables: Unloading modules:                               [  OK  ]
# chkconfig iptables off
# chkconfig --list iptables
iptables        0:off   1:off   2:off   3:off   4:off   5:off   6:off

Disable SELinux. Open the config file and change the SELINUX variable from enforcing to disabled.
# vim /etc/selinux/config
 # This file controls the state of SELinux on the system.
 # SELINUX= can take one of these three values:
 #     enforcing - SELinux security policy is enforced.
 #     permissive - SELinux prints warnings instead of enforcing.
 #     disabled - No SELinux policy is loaded.
 SELINUX=disabled

DNS Setup including BIND, NTP, DHCP in a LAN   on a separate VirtualBox VM  

Even if you are using a DNS, Oracle recommends to list the public IP, VIP and private addresses

for each node in the hosts file on each node.

Domain:         example.com       Name Server: ns1.example.com            192.168.1.50
RAC Sub-Domain: grid.example.com  Name Server: gns.example.com            192.168.1.55
DHCP Server:    ns1.example.com
NTP  Server:    ns1.example.com
DHCP adresses:  192.168.1.100 ... 192.168.1.254

Configure DNS:

SCAN VIP 1     none        Selected by Oracle Clusterware    GRACE2-scan.grid.example.com    Virtual     Dynamic        DHCP                    GNS
SCAN VIP 2     none        Selected by Oracle Clusterware    GRACE2-scan.grid.example.com    Virtual     Dynamic        DHCP                    GNS
SCAN VIP 3     none        Selected by Oracle Clusterware    GRACE2-scan.grid.example.com    Virtual     Dynamic        DHCP                    GNS

 

Note: the cluster node VIPs and SCANs are obtained via DHCP and if GNS is up all DHCP  adresses should be found with nslookup. If you have problems with zone delegation add your GNS name server to /etc/resolv.conf

Setup User Accounts

NOTE: Oracle recommend different users for the installation of the Grid  Infrastructure (GI) and the Oracle RDBMS home. The GI will be installed in  a separate Oracle base, owned by user ‘grid.’ After the grid install the GI home will be owned by root, and inaccessible to unauthorized users.

Create OS groups using the command below. Enter these commands as the 'root' user:
  #/usr/sbin/groupadd -g 501 oinstall
  #/usr/sbin/groupadd -g 502 dba
  #/usr/sbin/groupadd -g 504 asmadmin
  #/usr/sbin/groupadd -g 506 asmdba
  #/usr/sbin/groupadd -g 507 asmoper

Create the users that will own the Oracle software using the commands:
  #/usr/sbin/useradd -u 501 -g oinstall -G asmadmin,asmdba,asmoper grid
  #/usr/sbin/useradd -u 502 -g oinstall -G dba,asmdba oracle
  $ id
  uid=501(grid) gid=54321(oinstall) groups=54321(oinstall),504(asmadmin),506(asmdba),507(asmoper)
  $ id
  uid=54321(oracle) gid=54321(oinstall) groups=54321(oinstall),501(vboxsf),506(adba),54322(dba)

For the C shell (csh or tcsh), add the following lines to the /etc/csh.login file:
  if ( $USER = "oracle" || $USER = "grid" ) then
  limit maxproc 16384
  limit descriptors 65536
  endif

Modify  /etc/security/limits.conf
  # oracle-rdbms-server-11gR2-preinstall setting for nofile soft limit is 1024
  oracle   soft   nofile    1024
  grid   soft   nofile    1024
  # oracle-rdbms-server-11gR2-preinstall setting for nofile hard limit is 65536
  oracle   hard   nofile    65536
  grid   hard   nofile    65536
  # oracle-rdbms-server-11gR2-preinstall setting for nproc soft limit is 2047
  oracle   soft   nproc    2047
  grid     soft   nproc    2047
  # oracle-rdbms-server-11gR2-preinstall setting for nproc hard limit is 16384
  oracle   hard   nproc    16384
  grid     hard   nproc    16384
  # oracle-rdbms-server-11gR2-preinstall setting for stack soft limit is 10240KB
  oracle   soft   stack    10240
  grid     soft   stack    10240
  # oracle-rdbms-server-11gR2-preinstall setting for stack hard limit is 32768KB
  oracle   hard   stack    32768
  grid     hard   stack    32768

Create Directories:
 - Have a separate ORACLE_BASE for both GRID and RDBMS install !
Create the Oracle Inventory Directory ( needed or 11.2.0.3 will ) 
To create the Oracle Inventory directory, enter the following commands as the root user:
  # mkdir -p /u01/app/oraInventory
  # chown -R grid:oinstall /u01/app/oraInventory

Creating the Oracle Grid Infrastructure Home Directory
To create the Grid Infrastructure home directory, enter the following commands as the root user:
  # mkdir -p /u01/app/grid
  # chown -R grid:oinstall /u01/app/grid
  # chmod -R 775 /u01/app/grid
  # mkdir -p /u01/app/11203/grid
  # chown -R grid:oinstall /u01//app/11203/grid
  # chmod -R 775 /u01/app/11203/grid

Creating the Oracle Base Directory
  To create the Oracle Base directory, enter the following commands as the root user:
  # mkdir -p /u01/app/oracle
  # chown -R oracle:oinstall /u01/app/oracle
  # chmod -R 775 /u01/app/oracle

Creating the Oracle RDBMS Home Directory
  To create the Oracle RDBMS Home directory, enter the following commands as the root user:
  # mkdir -p /u01/app/oracle/product/11203/racdb
  # chown -R oracle:oinstall /u01/app/oracle/product/11203/racdb
  # chmod -R 775 /u01/app/oracle/product/11203/racdb

Add divider=10″ to /boot/grub/grub.conf
Finally, add “divider=10″ to the boot parameters in grub.conf to improve VM performance. 
This is often recommended as a way to reduce host CPU utilization when a VM is idle, but 
it also improves overall guest performance. When I tried my first run-through of this 
process without this parameter enabled, the cluster configuration script bogged down 
terribly, and failed midway through creating the database

Start the "grac2" virtual machine by clicking the "Start" button on the toolbar. Ignore any network errors during the startup.
Log in to the "grac2" virtual machine as the "root" user so we can reconfigure the network settings to match the following.
    hostname: grac2.example.com
    IP Address eth0: 192.168.1.62 (public address)
    Default Gateway eth0: 192.168.1.1 (public address)
    IP Address eth1: 192.168.2.72 (private address)
    Default Gateway eth1: none
Amend the hostname in the "/etc/sysconfig/network" file.
    NETWORKING=yes
    HOSTNAME=grac2.example.com 
Check the MAC address of each of the available network connections. Don't worry that they are listed as "eth2" and "eth3". These are dynamically created connections because the MAC address of the "eth0" and "eth1" connections is incorrect.

# ifconfig -a | grep eth
eth2      Link encap:Ethernet  HWaddr 08:00:27:1F:2E:33  
eth3      Link encap:Ethernet  HWaddr 08:00:27:8E:6D:24  
Edit the "/etc/sysconfig/network-scripts/ifcfg-eth0", amending only the IPADDR and HWADDR settings as follows and deleting the UUID entry. Note, the HWADDR value comes from the "eth2" interface displayed above.
    IPADDR=192.168.1.62
    HWADDR=08:00:27:1F:2E:33 
Edit the "/etc/sysconfig/network-scripts/ifcfg-eth1", amending only the IPADDR and HWADDR settings as follows and deleting the UUID entry. Note, the HWADDR value comes from the "eth3" interface displayed above.
    HWADDR=08:00:27:8E:6D:24
    IPADDR=192.168.2.102

Grid post installation - Ologgerd process cosumes high CPU time
  It had been noticed that after a while, the ologgerd process can consume excessive CPU resource. 
  The ologgerd is part of Oracle Cluster Health Monitor and used by Oracle Support to troubleshoot RAC problems. 
  You can check that by starting top:  (sometime up we see up to 60% WA states ) 
  top - 15:02:38 up 15 min,  6 users,  load average: 3.70, 2.54, 1.78
    Tasks: 215 total,   2 running, 213 sleeping,   0 stopped,   0 zombie
    Cpu(s):  3.6%us,  8.9%sy,  0.0%ni, 55.4%id, 31.4%wa,  0.0%hi,  0.8%si,  0.0%st
    Mem:   3234376k total,  2512568k used,   721808k free,   108508k buffers

     5602 root      RT   0  501m 145m  60m S 48.1  4.6   0:31.29 ologgerd    
If ologgerd process is consuming a lot of CPU, you can stop it by executing:
# crsctl stop resource ora.crf -init
  Now top looks good as IDLE CPU time increases from 55 % to 95 % !
  hrac1: 
    top - 15:07:56 up 20 min,  6 users,  load average: 2.57, 3.33, 2.41

 If you want to disable ologgerd permanently, then execute:
 # crsctl delete resource ora.crf -init

6 thoughts on “Installing Oracle RAC 11.2.0.3, OEL 6.3 and Virtualbox 4.2 with GNS”

  1. [root@ns1 named]# service named restart
    Stopping named: [ OK ]
    Starting named:
    Error in named configuration:
    /etc/named.conf:43: open: /etc/named.rfc1912.zones: file not found
    [FAILED]

  2. Your are right- I had a typo in the above tables.
    Public and Private Interfaces should have a fixed / DNS based address.
    Only VIPs are resolved by GNS ( the GNS VIP is also fixded )

  3. Can you please help me out step by step procedure for configuring DNS Setup on node 1. As i have 2 virtual machine with name rac1 and rac2 , as i am not networking guy, please help me out to resolve this error. I tried most of the stuff appeared in google but i am still not cleared.

    Thanks

    1. Maybe the following article can help [ includes linux RPM install + Network conf ]
      From the above menu select :
      RAC -> RAC Networking -> Setup DNS,NTP,DHCP

      Anyway, for using RAC you really need some level of basic understanding of Networking
