build two node oracle rac 11gr2 11-2-0 3 with gns dns dhcp and haip1(1)

Build two node Oracle RAC 11gR2 11.2.0.3 with GNS (DNS, DHCP)

and HAIP

In the article you will have a look at how to use some Oracle VirtualBox

features to build two node Oracle 11gR2 (11.2.0.3) RAC system on Oracle

Enterprise Linux (OEL 6.1). The setup will implement a role separation with

different users for Oracle RDBMS and Oracle GI that is, user oracle and grid

respectively in order to split the responsibilities between DBAs and storage

administrators. The article will show you how to configure DHCP and a sample

DNS setup for GNS deployment. You will have a glimpse at deploying HAIP

feature allowing up to four private interconnect interfaces.

An overview to Oracle Virtualization solutions can be seen here. You can see

how to use Oracle VM VirtualBox to build a two node Solaris cluster here. For

information related to building a RAC 11gR2 cluster on OEL without GNS click

here.

In the article you will see how to configure Linux in an Oracle VM VirtualBox

Virtual machines, install Oracle GI, Oracle RDBMS and will create a policy

managed database and service.

The following software will be used:

1. Oracle 11gR2 (11.2.0.3) for Linux (x86-64). Patch 10404530. Download from MOS here.

2. Oracle Enterprise Linux OEL 6.1(x86-64). Download from here.

3. Oracle VM VirtualBox 4.1.2. Download from here.

Three virtual machines will be created and used.

1. OEL61A for RAC node oel61a 2. OEL61B for RAC node oel61b 3. OEL61 for DNS and DHCP server

Ideally a DNS server should be on a dedicated physical server not a part of

the cluster. Due to limited resources in this article DNS server will be

configured to meet the prerequisites for GI and RDBMS installation for later

node addition.

Two virtual machines, OEL61A and OEL61B, will be configured for RAC nodes

each with:

4GB RAM 300GB bootable disk (Disk space will be dynamically allocated not

a fixed size pre-allocation) NIC bridged for public interface in RAC with address

192.168.2.21/22 (first IP 192.168.2.21 on oel61a and second IP

192.168.2.22 on node oel61b). These are public interface in RAC.

NIC bridged for private interface in RAC with address 10.10.2.21/22 (first IP 10.10.2.21 on oel61a and second IP

10.10.2.22 on node oel61b). These are private interface in RAC.

NIC bridged for private interface in RAC with address 10.10.5.21/22 (first IP 10.10.5.21 on oel61a and second IP

10.10.5.22 on node oel61b). These are private interface in RAC. NIC bridged for private interface in RAC with address

10.10.10.21/22 (first IP 10.10.10.21 on oel61a and second IP

10.10.10.22 on node oel61b). These are private interface in RAC. 5 10GB attached shared disks for the ASM storage. (Normal

Redundancy ASM disk groups will be deployed).

Virtual machine OEL61 will be configured as follows (I will use it for add

node later on):

4GB RAM

300GB bootable disk (Disk space will be dynamically allocated not a fixed size pre-allocation)

NIC bridged for public interface in RAC with address

192.168.2.11 NIC bridged for private interface in RAC with address



10.10.10.11

The interfaces IP addresses will be as show in the table 1 below.

2. DNS and DHCP Setup Example for Grid Infrastructure GNS [ID 946452.1]

The article will cover the following topics

1. Create an OEL61A VM with OEL 6.1 as guest OS for node oel61a. 2. Configure the OEL61A VM to meet the prerequisites for GI and RAC

11.2.0.3 deployment.

3. Clone OEL61A to OEL61B. 4. Clone OEL61A to OEL61.

5. Set up DNS and DHCP server on OEL61. 6. Install GI 11.2.0.3 on oel61a and oel61b. 7. Install RAC RDBMS 11.2.0.3 on oel61a and oel61b. 8. Create a policy managed database RACDB oel61a and oel61b. 9. Verify database creation and create a service.

Create an OEL61A VM with OEL 6.1 as guest OS for node oel61a

In this section you will look at how to create a guest OEL 6.1 VM

using Oracle VM VirtualBox.

Press the New button on the menu bar and press Next.

Specify the name of the VM and type of the OS and press Next.

Specify the RAM for the OEL61A VM and press Next.

Specify root password and press Next to continue.

Specify create custom layout.

The following list specifies the file systems, and their respective

sizes, that will be created. Create /u01 last with size the remaining

part of the 300GB disk. The approach can be used to create any custom

size. Plan accordingly to have sufficient disk space.

1. / - 10000M 2. /boot - 10000M 3. /home - 10000M 4. /opt - 10000M 5. /tmp - 10000M 6. /usr - 10000M 7. /usr/local - 10000M 8. /var - 10000M 9. swap - 10000M 10. /u01 - the remaining disk space.

Press Create.

You have two options for time synchronization: an operating system configured

network time protocol (NTP), or Oracle Cluster Time Synchronization Service.

Oracle Cluster Time Synchronization Service is designed for organizations

whose cluster servers are unable to access NTP services. If you use NTP, then

the Oracle Cluster Time Synchronization daemon (ctssd) starts up in observer

mode. If you do not have NTP daemons, then ctssd starts up in active mode and

synchronizes time among cluster members without contacting an external time

server. So there are two options:

For enabling the NTP make sure that /etc/sysconfig/ntpd has the line

modified to include -x.

o OPTIONS=-x -u ntp:ntp -p /var/run/ntpd.pid

For disabling the NTP make sure that the NTP service is stopped and disabled for auto-start and there is not configuration file.

o /sbin/service ntpd stop

o chkconfig ntpd off

o mv /etc/ntp.conf to /etc/ntp.conf.org

In the article NTP is disabled.

Right click the VM and select Clone or press CTRL+O. Enter the new name, mark

the check box to reinitialize the MAC address of all network interfaces and

press Next button. Here a new OEL61B VM is created from OEL61A.

Select Full Clone and press Clone.

Wait until the clone succeeds. This procedure creates a full copy of the

original OEL61A including all of the 6 disks from OEL61A. As the intention is

to have the five disks shared across both OEL61A and OEL61B I will drop the

non OEL disks from OEL61B and will re-attach the shared disks to OEL61B.

After dropping the disks from OEL61B I re-attach the shared disks using the

following commands.

E:\vb>type oel61_att1.bat

VBoxManage storageattach OEL61B --storagectl "SATA Controller" --port 1 --

Make sure that you enable named service for auto-start issuing the following

Disable the firewall by issuing the following command on all nodes oel61,

chkconfig iptables off

For production systems it is strongly recommended to adjust the iptables

rules so that you can have access to the DNS server listening on port 53.

Here for simplicity the firewall is disabled.

Solution

1. For PRVE-0453 set RP_FILTER as indicated below on each node of the cluster.

[root@oel61a disks]# for i in /proc/sys/net/ipv4/conf/*/rp_filter ; do

> echo 2 > $i

> done

[root@oel61a disks]#

2. For PRVF-10406 ASM disk needs to be with right permissions and ownership.

3. For PRVF-5636 make sure that nslookup always returns for less than

10s. In the example below it takes 15 secs.

[root@oel61a bin]# time nslookup not-known

There are two types of Virtual IPs

1. Virtual IPs generated by GNS in the 192.168.2.X subnet 2. Virtual IOs generated by HAIP in the 169.254.X.X subnet

As per Note 11gR2 Grid Infrastructure Redundant Interconnect and

ora.cluster_interconnect.haip [ID 1210883.1] HAIP allocates Virtual IPs from

the reserved IPs in the 169.254.X.X subnet for both load balancing and

failover.

Those IPs generated by HAIP can also be seen using oifcfg
