Prev: Prepare Host
Install Linux (e)
- Create VirtualBox VM
- VirtualBox VM Settings
- OS Installation
- Linux Post Installation
- Install VirtualBox Addons
- Configure Bind DNS
- Prepare Linux for Oracle
Next: Create Cluster
- To connect to the new created virtual machine, create a connection in Putty for the new VM called collabn1 with the IP Address of 192.168.78.51.
|On Linux, simply open a terminal; on OS X open a Terminal from Applications->Utilities and enter ssh firstname.lastname@example.org on the commandline. Answer yes to import the host key when you connect to each host for the first time.|
|If there is a Firewall running on the host workstation then you may not be able to push to the RAC node. You either need to disable the firewall or edit the configuration to let the connection through.|
- Optionally, create another connection for collabn2 with the IP Address of 192.168.78.52 that will be created later as a clone of collabn1.
- Click Yes on the Security Alert dialog box.
|If connection fails, verify that Virtual Box Network Configuration step was executed|
|You !!!MUST!!! disable IPTABLES. Many folks missing this step and then DNS does not work|
[root@collabn1 ~]# service iptables stop iptables: Flushing firewall rules: [ OK ] iptables: Setting chains to policy ACCEPT: filter [ OK ] iptables: Unloading modules: [ OK ]
[root@collabn1 ~]# chkconfig iptables off
[root@collabn1 ~]# chkconfig --list iptables iptables 0:off 1:off 2:off 3:off 4:off 5:off 6:off
|Run "mount /dev/cdrom /media/cdrom/" command twice if you got "mount: /dev/sr0 already mounted or /media/cdrom/ busy" running it for the first time|
Run the following commands:
mkdir /media/cdrom mount /dev/cdrom /media/cdrom/ cd /etc/yum.repos.d mkdir /tmp/old.yum.repos.d mv * /tmp/old.yum.repos.d cat <<EOF > ol64.repo [OL64] name=Oracle Linux 6.4 x86_64 baseurl=file:///media//cdrom gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY gpgcheck=1 enabled=1 EOF
|There is also a 12c preinstall package available in Oracle Linux releases 6.6 and later. In that case, you can also install oracle-rdbms-server-12cR1-preinstall|
[root@collabn1 ~]# yum install -y oracle-rdbms-server-11gR2-preinstall .... Transaction Summary ======================================================================== Install 21 Package(s) Upgrade 2 Package(s) Total download size: 43 M ....

|Recent versions of the Unbreakable Enterprise Kernel have support for dtrace and the kernel-uek-devel package. As such if you get a dependency error when running the rpm install command, run the following command first: rpm -ivh /media/cdrom/Packages/libdtrace-ctf-0.4.1-1.x86_64.rpm , and then re-run the first rpm command.|
