Quickly deploy an Oracle RAC environment using an Oracle VM Template

Quickly deploy an Oracle RAC environment using an Oracle VM Template

Oracle VM templates are pre-packaged and pre-configured virtual machines. In the communication between enterprise-level customers, I often use "simple, fast, and error-free" to deploy applications using Oracle VM templates. The Oracle VM template saves customers several days to weeks of configuration time, which can truly help customers quickly deploy and launch applications. Oracle provides a tool named Deploycluster to quickly deploy the Oracle Database template in the Oracle VM environment. Deploycluster can be used to deploy a single-instance Oracle Database and a multi-node Oracle RAC environment.

There are two deployment methods to quickly deploy the Oracle RAC environment using the Oracle VM template:

• Production-Supported: where the shared disk is configured as physical devices passed through to the guest Oracle VMs.
• Test-Unsupported (not officially supported): where the shared disk is configured as virtual devices

Next I will talk about how to quickly deploy the Oracle RAC environment. Due to the limited lab environment, my deployment method is between the two: no physical hard disk is directly used, however, two Oracle VM servers are used to run RAC instances. The specific process is as follows:

1. Check the necessary software conditions for the Deploycluster tool:

[root@ovm199 ~]# python -V
Python 2.6.6
[root@ovm199 ~]# java -version
java version “1.7.0_45″
OpenJDK Runtime Environment (rhel-2.4.3.3.0.1.el6-x86_64 u45-b15)
OpenJDK 64-Bit Server VM (build 24.45-b08, mixed mode)
[root@ovm199 ~]# rpm -qa | grep bc
…
bc-1.06.95-1.el6.x86_64

2. log on to the Oracle VM Manager and perform the following operations:

• Import the downloaded DBRAC Template
• Modify the basic configurations of the imported template (CPU, memory, and network)
• Create five shared ASM Virtual Disks
• Clone two VMS at a time using the imported Template
• Add five shared ASM disks to two VMS respectively.

3. decompress the Deploycluster Tool

[root@ovm199 ~]# unzip DBRACOVM-Deploycluster-tool.zip

4. Create the netconfig. ini file.

[root@ovm199 deploycluster]# cat netconfig.ini
# Node specific information
NODE1=racnode1
NODE1IP=192.168.1.231
NODE1PRIV=racnode1-priv
NODE1PRIVIP=10.10.10.231
NODE1VIP=racnode1-vip
NODE1VIPIP=192.168.1.233
NODE2=racnode2
NODE2IP=192.168.1.232
NODE2PRIV=racnode2-priv
NODE2PRIVIP=10.10.10.232
NODE2VIP=racnode2-vip
NODE2VIPIP=192.168.1.234
# Common data
PUBADAP=eth0
PUBMASK=255.255.255.0
PUBGW=192.168.1.1
PRIVADAP=eth1
PRIVMASK=255.255.255.0
RACCLUSTERNAME=crs64bitR2
DOMAINNAME=localdomain # May be blank
DNSIP= # Starting from 2013 Templates allows multi value
# 11gR2 specific data
SCANNAME=racnode1-racnode2-scan
SCANIP=192.168.1.235

5. Run the Deploycluster Tool

[root@ovm199 deploycluster]# ./deploycluster.py -u admin -p OracleVM326 -M racnode.0,racnode.1 -N netconfig.ini
